How to cleanly and safely uninstall mysql client on RHEL server?
|
On RHEL server, if I remember correctly, I installed mariadb client by running: yum install mariadb Now I want to safely and cleanly uninstall it, how do I do it? I know that this task might be dangerous because uninstalling a software cleanly requires uninstalling its dependencies as well, but other software might be using those dependencies as well. it can be hard to tell which dependencies are still being used and which aren't. I don't want to mess up things on server so I ask here first for correct instruction.

can compiled perl v5.28.0 from src (with gcc 4.8.5) run on RHEL 5.5?
|
My question is about whether if it would be possible to run a compiled perl 5.28.0 from source (with GCC 4.8.5 on CentOS 7) to be able to be used on RHEL 5.5 (Tikanga) where GCC version is lower and so would be the other libs like libc, glibc, etc. Our production environment is running very old perl version (5.8.8) and due to security concerns, it is under heavy lock down, i.e. most of our servers lack make, gcc and related tools and there is no root access available to anyone I was wondering if it would be possible to compile perl from source i.e. latest 5.28.0 with GCC 4.8.5 AND try to use this compiled version on our production servers (with GCC 4.8.2). This will save me tonnes of headaches with slow bureaucracy and I can get going with my project with the new tools. Have not been able to find any discussion or hint about this subject. Can anyone shed some light? Thank you in advance. Update after 2 days: As it seems Perl 5.28 compiled on RHEL7 does not work on RHEL5.5. You will have to compile it on RHEL5.5 and make it relocatable for further usage on any server. So I Downloaded the RHEL 5.5 and CentOS5.5 ISOs and ran into bootable iso related issues. Couldn't make a suitable bootable disk for both rhel 5.5 and centos5.5. rhel5.5 iso was a single dvd image and upon doing file rhel5.5.iso on command prompt, it showed bootable. tried unebootin, rufous iso creator, dd command and created ISOs and tried all of them one by one, but couldn't get it to show boot menu. tried FAT, NTFS FS while making boot disk. Stuck here now. Centos5.5 iso came in 8 pieces of 600mb files. Had to create a single iso image out of it and found some online procedure to do it and made one ISO file. Got boot menu and looked like it worked. But then it got hung up on doing some sort of source media check test and couldn't proceed further. Found a fix related article that you imprint md5sum on iso and it should work but it didn't. Just now found something on grokbase and it mentions a new technique, that could take me forward from the point of failure mentioned in point no.3 above.

Python raw socket frames never received
|
I am using a RHEL6 computer and I try to communicate with a Windows XP computer via RAW sockets. When I receive a specific frame on my RHEL computer, a Python 2 script using RAW sockets processes the frame and changes the following fields before sending it to the Windows computer : Dest MAC Dest IP IP ID Checksum The packet arrives on my Windows XP computer, as I see the packet in Wireshark, but it never reaches the application layer, as the software that needs the packet doesn't react. This is how I create the sent packet : import socket, binascii, optparse s=socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(3)) s.bind(('eth1',0)) while True: result = s.recv(65535) if binascii.hexlify(result[30:34]).decode() == "<WANTED FRAME IP>": result2 = "<DEST_MAC>".decode("hex") + result[6:18] + "<IP_ID>".decode("hex") + result[20:24] + "<CHECKSUM>".decode("hex") + result[26:30] + "<DEST_IP>".decode("hex") + result[34:] s.send(result2) When I try using "classic" socket, the target software correctly receives the packet, but it's not the behavior I want as I have to use RAW sockets to send them. I tried sending with the same code other simples UDP packets, and I got the same behavior as a result, with the packet correctly seen on wireshark but never reaches application layer on my Windows XP. Any idea why my RAW socket packets are not correctly processed by the target?

xsltproc merging xml files not working

git add/stat extremely slow on RHEL
|
We have a large (~15 GB, ~40K files) and old (~5 years with daily updates) git repository full of media content. Recently the RHEL users started to complaint it takes a few minutes to perform such routine operations like add, stat and push. At the same time on Ubuntu we don't encounter any problem. We had a similar issue a year ago. That time the cause was that a few very large (>500 MB each) files were added but now it's not the case. One note that may be important: RHEL users use an old RHEL 6 with official packages only. Could you advise how to beat the issue described?

java processbuilder terminal width
|
So I have a shell script which when executed an executable will display lines as wide as your terminal width. When I execute the script using ProcessBuilder it automatically returns only the first 80 characters. I've tried a variety of things, like adding stty rows 50 cols 132 to the script, or trying to set some environment variables in ProcessBuilder but can't find a way to change the terminal width of the process. Running this on RHEL. ProcessBuilder p = new ProcessBuilder(new String[] {"/bin/ksh", "myscript.ksh"}); BufferedReader br = new BufferedReader(new InputStreamReader(p2.getInputStream())); String line; StringBuffer output = new StringBuffer(); while ((line = br.readLine()) != null) { System.out.println(line); }

I've tried a variety of things, like adding stty rows 50 cols 132 to the script, or trying to set some environment variables in ProcessBuilder but can't find a way to change the terminal width of the process. Running this on RHEL. ProcessBuilder p = new ProcessBuilder(new String[] {"/bin/ksh", "myscript.ksh"}); BufferedReader br = new BufferedReader(new InputStreamReader(p2.getInputStream())); String line; StringBuffer output = new StringBuffer(); while ((line = br.readLine()) != null) { System.out.println(line); }

Environment variable value loses backslash in database.yml
|
On a RHEL 7.2 server I've set up environment variables in /etc/environment similar to this: DB_LOGIN='DOMAIN\username' DB_PASSWORD='password' The file was then referenced as an EnvironmentFile in /etc/systemd/system/httpd.service.d/override.conf. After rebooting the server I can see that the env. var. is set properly (by running the env command). In my Rails environment, I have the following in my database.yml file based on what I learned from Failing to access environment variables within database.yml file : default: &default adapter: sqlserver ... username: <%= ENV['DB_LOGIN'] %> password: <%= ENV['DB_PASSWORD'] %> This setup works fine when executing my rake tasks. Also of note, when I run erb against the database.yml, it looks correct (the backslash is present). However in my Apache/Passenger configuration (httpd-2.4.6-40.el7_2.4.x86_64 and Phusion Passenger 5.1.7), the username loses the backslash (the value is DOMAINusername). I've changed the env var to have two backslashes (DOMAIN\\username) and then it works fine in the Apache/Passenger config, but my rake tasks fail due to the double backslash in the username. Is there a way to have an environment variable value that contains a backslash work in both of these situations? I'm not really looking to use a gem/plugin like Figaro or dotenv. Thanks for any guidance!

Running ASP.NET Core app from Amazon Linux 2 on Docker - Globalization
|
I have my ASP.NET Core app running beautifully (more or less) on microsoft/aspnetcore:2.0-jessie . Now I want to try to get it to deploy to amazonlinux:2 . So far, the biggest hurdle has been libicu . I tried setting Globalization to Invariant, but this caused weird failures in, e.g., mySQL database calls. Here's the relevant step from my Dockerfile: RUN curl -L --http1.1 [URL] --output icu.tgz \ && tar -xf icu.tgz -C / \ && export LD_LIBRARY_PATH=/usr/local/lib \ && rm icu.tgz (SourceForge was down while I was trying to work on this yesterday, which didn't improve matters.) In any case, I still get the message of doom from .NET Core: FailFast: Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support. Any suggestions how to proceed?

NodeJS fs.unlink() deletes the files but the OS can still find them
|
I am using the following node.js code to delete files that I don't need. fs.unlink(downloadsFolder + '/' + file, function(err){ if (err) throw err; console.log("This file will be deleted." + file) }); When I list my directory, I can verify that the files are gone. However, when I run this command, I can still see them marked as (deleted) and still taking up disk space. dzdo lsof -L | grep -i deleted node 48782 root 600743243 403197165 /mnt/downloads/file_1516312894734.csv (deleted) node 48782 root 14999 403197166 /mnt/downloads/file_1516729327306.csv (deleted) As a temporary thing, I restart the node server to release all those "file handles" and they are gone. Why doesn't fs.unlink() do this automatically?

How to get a dual head configuration running on VirtualBox / RHEL 5.11
|
We have production machines running RedHat RHEL 5.11 / X.org version 7.1.1. The supplier of these machines provides a VirtualBox VM to allow software development on conventional computers, i.e. away from the production floor. I would like to configure this VM for dual head / dual monitor / dual screen usage. Step 1: The VM in VirtualBox Manager is configured for maximum video memory and 2 monitors. Step 2: VirtualBox GuestAdditions are installed, version corresponding to the Virtual Box application. Step 3: /etc/X11/xorg.conf is modified to support 2 devices, 2 screens and 2 monitors, all configured for the vboxvideo driver. The content is shown below: # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "Multihead layout" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "LCD Panel 1600x1200" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Monitor Vendor" ModelName "LCD Panel 1600x1200" EndSection Section "Device" Identifier "Videocard0" Driver "vboxvideo" BusID "PCI:0:2:0" Screen 0 EndSection Section "Device" Identifier "Videocard1" Driver "vboxvideo" BusID "PCI:0:2:1" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1600x1200" "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Videocard1" Monitor "Monitor1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1600x1200" "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection Step 4: reboot the system I expect now that the system is set-up and ready to show two screens on my computer. Alas, it only shows Screen0. Observations: /var/log/Xorg.0.log shows no errors, but a couple of warnings: (WW) VBoxVideo(0): Failed to set up write-combining range (0xe0000000,0x8000000) In the same log file, only the instance VBoxVideo(0) is mentioned; there is no reference to VBoxVideo(1) lspci also shows only one instance of the VBox video driver: 00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter In VB Manager -> View only Virtual Screen 0 is said to be enabled; the other screen is available, but an "enable" option is presented, that appears to do nothing when selected. Everything else I have seen seems to be consistent: the second screen is nowhere found on my RHEL VM. Questions: What is the importance of the warning on write-combining? Is this related to this problem? Is vboxvideo driver / pseudo card a dual head card or should I instantiate a second card? What are the correct magic numbers for the BusID of the second "Device"? Any other recommendation to get this configuration up-n-running?

My installed GCC version is behind my installed Redhat developer toolset version
|
I have been searching for the answer to this for a while. I'm on RHEL 6.x and I am trying to upgrade gcc in order to install a package. Also, I have a super old version of gcc and it's time to upgrade anyway. (For now, let's assume that an OS upgrade is out of the question, so if this DOES require an OS upgrade, the package will have to wait.) I found that the best way to upgrade gcc is by using Redhat Developer Toolset. I look into it, and find that I already have devtoolset-4 installed, which, to my understanding, installs gcc version 5.2.1 with it. Yet, for some reason, my current gcc version is 4.4.7 . Any idea why this would happen?

Problems with using uuencode on RHEL to send mail attachment
|
I have a unique situation where I'm going from an AIX platform to RHEL for a vendor supported application. Within the application, I can send a command (limited to the amount of characters I can send) that will email me results of a print job. To do this in AIX, I'm passing the following command: uuencode temp.txt | mail -s "test" email@address.com This sends standard output to the email as an attachment named temp.txt. Temp.txt doesn't exist on the AIX server. I have downloaded the rpm for uuencode for Linux, but it doesn't work in the same fashion. It sends an email with what looks like garbage (could be missing MIME header). I'm looking for a similar command. To simulate outside of the application, I use the following in AIX: echo "testing mail" | uuencode temp.txt | mail -s "test" email@address.com I know mailx -a <filename> would work if I had a filename, unfortunately I'm working with standard output vs a file. Any help will be appreciated.

To do this in AIX, I'm passing the following command: uuencode temp.txt | mail -s "test" email@address.com This sends standard output to the email as an attachment named temp.txt. Temp.txt doesn't exist on the AIX server. I have downloaded the rpm for uuencode for Linux, but it doesn't work in the same fashion. It sends an email with what looks like garbage (could be missing MIME header). I'm looking for a similar command. To simulate outside of the application, I use the following in AIX: echo "testing mail" | uuencode temp.txt | mail -s "test" email@address.com I know mailx -a <filename> would work if I had a filename, unfortunately I'm working with standard output vs a file. Any help will be appreciated.

QTouchEvent Ubuntu 14.04 vs RHEL 7.4
|
When a touchscreen monitor is pressed, using Qt4.8, viewportEvent(QEvent *event) fires the correct signals ( QEvent::TouchBegin , QEvent::TouchUpdate ) on a PC with Ubuntu 14.04 installed. For the exact same source code compiled on a PC running RHEL 7.4, only mouse events are returned. dmesg and lsusb commands on both PCs return the same results, indicating to me no driver issues. Why would RHEL not return the correct signals in this case? I wish to use multitouch on RHEL PCs.

how to add labels in every docker remote build
|
I have a docker remote server to build all my images, now I need to add labels to every image build in the remote. I know that adding --label label=value works from local but when I call the remote docker I need to add specific labels to all image build in the remote docker. In other words I want to add the OS version and the docker version to every image even if I call from local without any label in the command line I want to do something like: docker -H <remote-docker> build -f ./Dockerfile -t image:version and when I do a docker inspect to the image stored in the remote docker the labels have: Labels: { "os_version": 0.0.1, "docker_version": 1.17.0 } Without I specify --label every time I build in remote docker. Someone know how to add this labels in every build?

Java Compiler keeps saying "error while writing className: className.class (Permission denied)"
|
I'm working on a Tomcat WebApp for my university which enables students to compile their Java codes and see the trace. I'm installing it on a RHEL7 VM. But when I test the compilation function (this one is not implemented by me), the method I'm providing returns this: error while writing className: className.class (Permission denied) Error on line 1 in className.java I'll show you the method I think is generating this: public String compileJavaCode(String javaCode, String javaFileName, File workingDir) throws IOException, TimeoutException{ javax.tools.JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>(); StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null); this.createJavaFile(javaCode, javaFileName, workingDir); JavaFileObject file = new JavaSourceFromString(javaFileName, javaCode); Iterable<? extends JavaFileObject> compilationUnits = Arrays.asList(file); compiler.getTask(null, fileManager, diagnostics, null, null, compilationUnits).call(); String diagn = ""; for ( Diagnostic<? extends JavaFileObject> diagnostic : diagnostics.getDiagnostics()){ diagn+=diagnostic.getMessage(null)+"\n";//E.g. cannot find symbol symbol: variable variablename diagn+="Error on line "+Long.toString(diagnostic.getLineNumber())+" in "+diagnostic.getSource().toUri();//E.g. Error on line 22 in ClassName.java } fileManager.close(); compiler.run(null, null, null, workingDir.getAbsolutePath()+File.separator+javaFileName); return diagn; } Students will see the content of that diagn variable as a result for their code submission. Fun fact is that I manage to get the className.class in the workingDir directory but I keep getting that error from the for cycle above. Could the problem be compiler.getTask(...).call() ? I mean maybe compiler.run is able to generate the .class correctly but the compiler.getTask(...).call() is trying to write the .class somewhere else I don't have permission to write in. P.S. This is a pretty legacy code so please be merciful with it. :) As asked by @Alexander, this is the content of the Java file: public class Sommatore { public int somma(int i, int j) { return i+j; } public int differenza(int i, int j) { return i-j; } }

Docker nginx SELinux (centOS/RHEL) with 403 forbidden access
|
So my Dockerfile runs via docker-compose using: Dockerfile FROM nginx #COPY conf COPY myapp/ /usr/share/nginx/html RUN chmod -R 664 /usr/share/nginx/html RUN chown -R nginx /usr/share/nginx/html RUN chcon -R -t httpd_sys_content_t /usr/share/nginx/html This is on RHEL 6.x, Docker is old 1.7 or something as well. I don't even need "run chmod/chown/chcon" for most environments!! The dockerfile works just fine on windows. However, I still get 403 Forbidden errors whenever nginx tries to access ANY file in /usr/share/nginx/html. What is the correct way to setup nginx in a docker container and avoid these SElinux problems? (SElinux is on "Enforcing") In fact, if you do RUN/CMD ls -l we can see nginx is the user who owns that folder and it has the right permissions! So what the heck is going on?

Authenticating SSH between CentOS & Cisco appliances
|
I am new to scripting, so please forgive this question. Having done extensive research am not able to find a suitable solution. Currently I have a Python script which is required to SSH from CentOS into Cisco (and other) firewall appliances. Once logged in, certain actions are carried out. Currently, we are storing our username and password in a plaintext file and calling that file when the Python script requires it. However, if the CentOS server is compromised, the attacker now has access to the plaintext credentials to the firewall and would be able to get the IP address from the Python script. I have looked at using SSH-Agent as a means of bypassing passwords, however, if the CentOS server is compromised won't the attacker still be able to access the firewall through the Python script? Really, I am looking for a way to protect the firewall from unauthorized access, should the CentOS server be compromised. I have also considered using obfuscation but doesn't seem suitable. Wondering what options I have here. Sorry for my bad english.

Carbon-cache fails to start with no error
|
Trying to install Graphite on CentOS 7, I'm met with this curious situation. When trying to start carbon-cache via service, it will report OK Starting carbon-cache (via systemctl): [ OK ] When checking its status, however I get FAILED: Usage: bin/carbon-cache.py {start|stop|restart|status} [FAILED] (Yes, failed is on another line). Carbon-cache log doesn't show anything - it doesn't even write to it. Any ideas of what might have gone wrong?

When can keytool and java directory be different
|
Can anyone please suggest me a scenario such that the which java and which keytool gives me two different directories(Results). I have done a lot of google but all of them say that the keytool and the jre dir are the same so both the above commands will give the same result. Any help will be much appreciated.

Upgrading Python on RHEL 7
|
TL;DR How do I get Python 2.7.9+ on RHEL 7? I'm using Ansible for configuration management of a RHEL 7 server. I've run into a number of cases where an Ansible module (or whatever action it was trying to perform) requires Python 2.7.9+, but RHEL 7 (tested on 7.1 and 7.3) only come with Python 2.7.5. I see a few options: Installing through a different package repository. I was looking around for an easy way to upgrade though yum , but couldn't find one. Is there a repository that has Python 2.7.9+? Sub-question: Is there a site to search for a given version of a given package, and then find out what repository(s) it exists in? Installing Python 2.7.9+ from source. I tried to do this, but I apparently couldn't get the compilation to pick up system libraries like zlib, so a bunch of the Ansible modules ended up failing when using it as the ansible_python_interpreter . Possible that I could spend more time and get that working. Use Python 3. Ansible has experimental Python 3 support , but I'm worried about the unknown stability of this. Any advice on the easiest path forward? I'm relatively new to system administration, so very possible there's a straightforward solution I'm missing. Thanks!

What is the greylist.txt in a kmod rpm package
|
Many device driver appear as a kmod-<drivername> rpm package in CentOS/RHEL, and there is always a greylist.txt in these package, with some kernel symbol as its contents. Here are an example: [root@localhost download]# rpm -ql kmod-qed /etc/depmod.d/qed.conf /lib/modules/3.10.0-327.36.2.el7.x86_64 /lib/modules/3.10.0-327.36.2.el7.x86_64/extra /lib/modules/3.10.0-327.36.2.el7.x86_64/extra/qed /lib/modules/3.10.0-327.36.2.el7.x86_64/extra/qed/qed.ko /usr/share/doc/kmod-qed/greylist.txt [root@localhost download]# cat /usr/share/doc/kmod-qed/greylist.txt bitmap_clear bitmap_set __fentry__ ioremap_wc pci_enable_msi_range pci_enable_msix_range pci_ioremap_bar pci_is_pcie pci_read_config_byte pci_read_config_word pci_save_state release_firmware request_firmware __smp_mb__after_atomic __stack_chk_fail synchronize_irq tasklet_init __tasklet_schedule vzalloc x86_dma_fallback_dev zlib_inflate zlib_inflateEnd zlib_inflateInit2 zlib_inflate_workspacesize I guess it must have something to do with the kernel ABI whitelist, but what exactly is the purpose of this greylist file? and how was it generated while packaging the kmod rpm. Thanks.

Simulating RISCV on RHEL5 -- Missing libmpc-devel
|
My goal is to simulate RISCV in VCS on RHEL 5.11. I am following the lowRISC tagged memory tutorial, environment setup guide: [URL] The apt-get commands are substituted with yum and equivalent packages, per the GNU toolchain repo readme: [URL] sudo yum install autoconf automake libmpc-devel mpfr-devel gmp-devel gawk bison flex texinfo patchutils gcc gcc-c++ The libmpc-devel package cannot be found, and I cannot build GCC for RISCV without it. I believe this package can be found for RHEL6, but I do not have VCS available on a RHEL6 machine. Is there a workaround for this issue -- e.g. can I build GCC for RISCV on another machine, then do compilation and simulation on different boxes?

Upgrading Python package in Redhat Software Collections (RHSCL)
|
I'm using SCL to manage different versions of Python on a machine, but I'm having trouble updating and installing packages at the SCL level. I am trying to upgrade pip. First I tried scl enable python27 'pip install -U pip' but I do not have permissions to touch the SCL python site-packages. Then I run sudo scl enable python27 'pip install -U pip' this completes successfully. However, this happens: $ scl enable python27 pip --version Traceback (most recent call last): File "/opt/rh/python27/root/usr/bin/pip", line 7, in <module> from pip import main ImportError: No module named pip. $ sudo scl enable python27 pip --version works, however. Upon further inspection, it looked like the site-packages/pip directory was created with the wrong permissions. What is the recommended way to manage parts of an SCL install that require root?

Bash Script that gets a count of running processes and then emails if over a certain threshold
|
I am trying to create a script to grab the current number of running processes and the if that number is over 1000 then send me an email. I am trying to do this in a bash script that I will just use a cron job to call it. The code I am using is below and I am sure I just have something out of place and just need another set of eyes. PCOUNT=$(cat /proc/loadavg|awk '{print $4}'|awk -F/ '{print $2}') if [$PCOUNT > 100]; then mail -s "Process Count" email@example.com fi

egrep working differently on SunOS and RHEL

I've an egrep statement(as a part of a script) purpose of which is to check for any characters other than ASCII characters 0-9, a-z, A-Z, space, enter, newline .

Why don't my QIcons show in my QMenu when I run my PyQt application as root?
|
I have a PyQt4 application I am working on and I have an issue that I can't seem to solve. I have a bunch of QActions that have a valid QIcon set. These QActions are on a QToolBar, as well as a QMenu. The QIcons show on the QToolBar and the QMenu just fine when run as a normal user, but if I run the application with sudo or when logged in as root, the QIcons show on the QToolBar, but not in the QMenu. I am running this on RHEL 6.7 and have checked permissions of all my files. Any idea what might be happening?

invalid UTF8 string when i use QJsonDocument::fromJson
|
In the latest version of Ubuntu, code by qt creator. Qt version is qt 5.41. When I use QJsonDocument :: fromJson create json objects, json object is created successfully. Code is as follows: #include <QJsonDocument> #include <QDebug> int main(int argc,char **argv){ QString str = "{\"chinese\":\"china 中国\"}"; QJsonDocument json; QJsonParseError error; json = QJsonDocument::fromJson(str.toUtf8(),&error); qDebug()<<json.toJson(); //In Rhel5 Result:NULL qDebug()<<error.errorString(); //In Rhel5 Result:invalid UTF8 string" str = "{\"english\":\"china english\"}"; json = QJsonDocument::fromJson(str.toUtf8(),&error); qDebug()<<json.toJson(); //In Rhel5 Result successful : // { // "english": "china english" // } qDebug()<<error.errorString();//In Rhel5 Result:no error occurred"" return 0; } However, when the exact same code to run on rhel5 , I got a description of the error: invalid UTF8 string. On rhel5 , compiled qt5 library functions, so you can execute programs on qt5 rhel5. When json string is in English, rhel5 run properly, correct json string. In addition, rhel5 support utf-8 encoded.

Build and install Rabbitmq on RHEL
|
I need to install rabbimtmq cluster on one of our campus cluster where i don't have root access. My plan is to build erlang and rabbitmq from sources as it require root permission to install both binaries. I download erlang version 18.2 and built on RHEL node. Then i try to install rabbimq 3.6.0 sources but it fails with following error. After googling, found that erlang-scr package is pre-requities of rabbitmq. How can i provide that? (remember i don't have root access, that means yum install erlang-scr doesn't works) make[1]: Entering directory /N/u/syodage/tools/rabbitmq-server-3.6.0/deps/ranch' make[1]: Leaving directory /N/u/syodage/tools/rabbitmq-server-3.6.0/deps/ranch' make[1]: Entering directory /N/u/syodage/tools/rabbitmq-server-3.6.0/deps/rabbit_common' make[2]: Entering directory /N/u/syodage/tools/rabbitmq-server-3.6.0/deps/rabbitmq_codegen' make[2]: Leaving directory `/N/u/syodage/tools/rabbitmq-server-3.6.0/deps/rabbitmq_codegen' ERLC app_utils.erl credit_flow.erl gen_server2.erl mirrored_supervisor.erl mochijson2.erl pmon.erl priority_queue.erl rabbit_amqqueue.erl rabbit_auth_mechanism.erl rabbit_authn_backend.erl rabbit_authz_backend.erl rabbit_backing_queue.erl rabbit_basic.erl rabbit_binary_generator.erl rabbit_binary_parser.erl rabbit_channel.erl rabbit_channel_interceptor.erl rabbit_command_assembler.erl rabbit_control_misc.erl rabbit_data_coercion.erl rabbit_event.erl rabbit_exchange_decorator.erl rabbit_exchange_type.erl rabbit_framing_amqp_0_8.erl rabbit_framing_amqp_0_9_1.erl rabbit_heartbeat.erl rabbit_misc.erl rabbit_msg_store_index.erl rabbit_net.erl rabbit_networking.erl rabbit_nodes.erl rabbit_password_hashing.erl rabbit_policy_validator.erl rabbit_queue_collector.erl rabbit_queue_decorator.erl rabbit_queue_master_locator.erl rabbit_reader.erl rabbit_runtime_parameter.erl rabbit_writer.erl ssl_compat.erl supervisor2.erl time_compat.erl src/rabbit_net.erl:27: can't find include lib "ssl/src/ssl_api.hrl" make[2]: *** [ebin/rabbit_common.app] Error 1

Segmentation fault in mono using pinvoke on liblvm2app.so
|
I'm trying to write a c# program in mono to get information about the vgs (volume groups), lvs (logical volumes) and pvs (physical volumes). I'm using a centOS7 system. To get information about lvm, an API is defined ( [URL] ). The example program in c++ works perfectly ( [URL] ) with the API linked above. But i'm having trouble, using pinvoke for the API calls from my c# program. I have managed to get version data. Therefore i assume, pinvoking the library is possible. lvm2app.h Wrapper class: public class liblvm2wrapper { [DllImport ("liblvm2app.so")] public static extern IntPtr lvm_init (IntPtr system_dir); [DllImport ("liblvm2app.so")] public static extern IntPtr lvm_errmsg (IntPtr libh); [DllImport ("liblvm2app.so", CharSet = CharSet.Ansi)] public static extern IntPtr lvm_library_get_version (); [DllImport ("liblvm2app.so", CharSet = CharSet.Ansi)] public static extern IntPtr lvm_vg_open(IntPtr libh, [MarshalAs (UnmanagedType.LPStr)]string vgname, [MarshalAs (UnmanagedType.LPStr)]string mode, int flags); [DllImport ("liblvm2app.so")] public static extern void lvm_quit (IntPtr libh); } Main class Program { static void Main(string[] args) { IntPtr lvmHandle = liblvm2.lvm_init(IntPtr.Zero); if(lvmHandle == IntPtr.Zero) return; IntPtr versionPtr = liblvm2wrapper.lvm_library_get_version(); string version = Marshal.PtrToStringAnsi(versionPtr); // works // segFault occurs at the next line of code, if the name describes an existing vg // bash: line 1: 43812 Segmentation fault (core dumped) '/usr/bin/mono' --debug --debugger-agent=transport=dt_socket,address=127.0.0.1:51779 "home/user/Documents/test/bin/x64/Debug/test.exe" IntPtr vgHandle = liblvm2wrapper.lvm_vg_open(lvmHandle , "volume_group", "r", 0); if(vgHandle == IntPtr.Zero) { // if the string ("volume_group") passed to the function lvm_vg_open does not describe ane existing volume group, an empty pointer is returned and a valid error message is obtained calling the function below (lvm_errmsg) Console.WriteLine(Marshal.PtrToStringAnsi(liblvm2wrapper.lvm_errmsg(lvmHandle))); } liblvm2wrapper.lvm_quit(lvmHandle); } } From what i have heard, segmentation faults should be analized using gdb.

System V message queue sends are very slow with selinux
|
My System V message queue sends have slowed down significantly with selinux enabled. With selinux disabled my test program can do 1000 sends (msgsnd) in about 1,500 microseconds. With selinux enabled it takes about 25,000 microseconds to do 1,000 sends. Is there anything I can do to speed up this up? unsigned long long gettime() { struct timeval gtime; unsigned long long usecs; gettimeofday (>ime,NULL); usecs = (((unsigned long long)gtime.tv_sec) * 1000000) + gtime.tv_usec; return usecs; } key_t keyval = 102715; int qid; if((qid = msgget( keyval, IPC_CREAT | 0660 )) == -1) { printf("msgget failed\n"); return -1; } printf("qid = %d\n",qid); struct XmitMsg { long mtype; int data1; int data2; } msg; struct XmitMsg xmitmsg; xmitmsg.mtype=1; xmitmsg.data1=10; xmitmsg.data2=20; int length = sizeof(struct XmitMsg) - sizeof(long); unsigned long long beforeTime=gettime(); for (int i=0; i<1000; i++) { int result = msgsnd( qid, &xmitmsg, length, 0); if (result != 0 ) printf("result=%d\n",result); } unsigned long long afterTime=gettime(); printf("time diff=%llu\n",afterTime-beforeTime);

Kickstart configurations -- ignoredisk and bootloader usage
|
From the Red Hat website, I found the following link ( Red Hat website ) shows the expression to ignoredisk. ignoredisk_option From my understanding, if i set this option to ignoredisk --only-use=sda The image will be deployed and installed on to the sda drive on the client host. 1.If I expect to have this image to be installed on the sdb , then I just changed sda to sdb , is this correct ? 2. bootloader --append=" crashkernel=auto" --location=mbr --boot-drive=sdb For the bootload boot-drive, I should also change it to sdb if I expect the system to be installed onto sdb , is this correct? Thanks

Compiling graph-tool on RHEL
|
I need to use Python's graph-tool on a RHEL6 server. The system administrator has not been able to install the boost library from a repository that he trusts (or whatever), so has installed it at /usr/local/boost_1_59_0/ Inside are two directories, boost/ and libs/ which I am taking to be the header and libs directories. I downloaded the source: wget [URL] And unpacking that, I tried: env CPPFLAGS='-I/home/foo/sw/include' LDFLAGS='-L/home/foo/sw/lib/' ./configure but that didn't give any different result than "./configure" by itself. It says: checking for boostlib >= 1.53.0... configure: error: We could not detect the boost libraries (version 1.53 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in . See [URL] for more documentation.

Compiling graph-tool on RHEL I need to use Python's graph-tool on a RHEL6 server. The system administrator has not been able to install the boost library from a repository that he trusts (or whatever), so has installed it at /usr/local/boost_1_59_0/ Inside are two directories, boost/ and libs/ which I am taking to be the header and libs directories. I downloaded the source: wget [URL] And unpacking that, I tried: env CPPFLAGS='-I/home/foo/sw/include' LDFLAGS='-L/home/foo/sw/lib/' ./configure but that didn't give any different result than "./configure" by itself. It says: checking for boostlib >= 1.53.0... configure: error: We could not detect the boost libraries (version 1.53 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option.

RHEL6 installed wrong version of rpmforge
|
I installed the wrong version of rpmforge for el7. Then I ran an update which installed this package on my system python-crypto-2.6.1-1.el7.rf.x86_64 Notice the el7 but I am on rhel6. I then realized and removed the wrong repository and installed the right one for el6. $ rpm -qa | grep rpmfor rpmforge-release-0.5.2-2.el6.rf.x86_64 But the above process has broken the update process, which I know I could work around using --skip-broken option. How do I downgrade for the above mentioned package. I tried to uninstall and install it back again but I get this error: Error: Trying to remove "c4ebpl", which is protected It shows me some protected packages which can't be removed. Update process using sudo yum update gives me this error: Error: Package: python-crypto-2.6.1-1.el7.rf.x86_64 (rpmforge) Requires: libgmp.so.10()(64bit) Error: Package: python-crypto-2.6.1-1.el7.rf.x86_64 (rpmforge) Requires: libc.so.6(GLIBC_2.14)(64bit) Error: Package: python-crypto-2.6.1-1.el7.rf.x86_64 (rpmforge) Requires: python(abi) = 2.7 Installed: python-2.6.6-52.el6.x86_64 (@el66/$releasever) python(abi) = 2.6 Error: Package: python-crypto-2.6.1-1.el7.rf.x86_64 (rpmforge) Requires: libpython2.7.so.1.0()(64bit) You could try using --skip-broken to work around the problem Would anyone know how to downgrade to the original packages? Is there a way to do a factory reset? Or do I need to re-install linux again? Some things I tried: I deleted the python-crypto.x86_64 package using this command sudo rpm --nodeps -e python-crypto.x86_64 And the update went through.

how to restrict specific hosts from connecting to pgbouncer?
|
I am running my postgres-9.2 on 6432 port and pgbouncer on 5432 port. Few of my colleagues client machines have the firewall connection permissions on 5432 port on server machine. But as a DB admin, I wanted to restrict some IP addresses from accessing the database. But, though I block in the pg_hba.conf file, since the pgbouncer port is allowed, they are able to access. I can block at the OS firewall level but I don't want to take the help of my system administrator. So, is there any way to restrict and deny IP addresses from accessing the pgbouncer as we generally do through pg_hba.conf for the postgresql. Please suggest.

Cannot open display while running X Apps as another user
|
I am currently using X11RDP to connect to a RHEL 6.5 endpoint , as root user. All X apps work fine, and directed properly to the right display (say 11.0). Now if I switch to another user ( su - user1 ), then I try to open any X app (say xterm) it will be unable to open the display (even though it is also 11.0). I do not believe the problem to be with xauth (magic cookies, etc), or the DISPLAY environment variable not being set correctly, or allowing connection with xhost + ; but rather something with XRDP . Any help would be appreciated.

'pecl install ibm_db2' can't find library
|
I'm trying to install ibm_db2 through pecl: pecl install ibm_db2 Then when it asks for an install dir, I have tried various places only to have the same result. It goes through a bunch of checks etc., then tries to 'make' and gets an error: /usr/bin/ld: skipping incompatible /home/db2inst1/sqllib/lib32//libdb2.so when searching for -ldb2 /usr/bin/ld: cannot find -ldb2 It always looks there for the libraries. And they exist, because when I execute: locate libdb2.so It displays: /opt/ibm/db2/V10.1/lib32/libdb2.so /opt/ibm/db2/V10.1/lib32/libdb2.so.1 /opt/ibm/db2/V10.1/lib64/libdb2.so /opt/ibm/db2/V10.1/lib64/libdb2.so.1 But they're in /opt/ibm. I was looking at this link: pecl instal ibm_db2 fails , it seems like it's something to do with the headers/libraries being configured incorrectly? I am currently running RHEL 6.6.

HTML/CSS/JS desktop application runtime for RHEL6
|
I have a software user interface built with node-webkit, which works great for most platforms. However, on RedHat Linux 6 OS Chromium is not supported, and node.js requires some hacky methods that I shouldn't be allowed to automate for other companies' nodes. This is because RHEL6 has locked glibc version to 2.12 and the gtk version to 2.18 . Basically, I'd really like to avoid having to build an entire new UI (in a different language than HTML/CSS/JS) just for RHEL6 users. Is there a desktop runtime such as node-webkit for RHEL6 that I could use as a base for the front end of my software?

Can I specify how often a non-delivery report will get sent for a mail on the mail queue
|
BACKGROUND: I am running exim4 on RHEL 6.6. I have sent a message and it currently resides on exims mail queue and will continue to be there for at least 5 days. I believe a Non-Delivery report will be sent to me once every 24 hours telling me that my mail has not been sent. Can I ask exim to send a Non-Delivery Report to me once every 6 hours instead of once every 24 hours? So in a 24 hour period I would like to receive 4 non-delivery reports from my exim server telling me my mail is undelivered. Is it possible to do this? Any links or information surrounding this topic would be appreciated.

libfaketime and java on RHEL 5 / RHEL 6
|
In order to test java-code with date / time set into the past or future I want to try libfaketime (currently we just adjust the system clock, but it causes much trouble like non working kerberos, etc). I try with this small test program: $ cat time.java import java.util.*; class TimeTest { public static void main(String[] s) { long timeInMillis = System.currentTimeMillis(); Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(timeInMillis); java.util.Date date = cal.getTime(); System.out.println("Date: " + date); } } And executes this: LD_ASSUME_KERNEL=2.6.18 LD_PRELOAD=/usr/lib64/libfaketime.so.1 FAKETIME="-15d" /opt/IBM/WebSphere/AppServer/java_1.7_64/bin/java TimeTest Invalid clock_id for clock_gettime: -172402[root@myhost ~]# But as you can see I just get an error message. The test is performed on a RHEL 6.5 server, kernel 2.6.32-431 and libfaketime 0.9.6 Do you have any suggestions how I can solve this? I'm also interested in hearing your experiences with libfaketime and java on RHEL. I have also reported this issue at: [URL] Best reagards, Erling

Strtotime giving different results
|
So I have a dev box running CentOs6.5 and a server running RHEL 7 if I do the date command from both boxes I get "Mon Sep 8 09:36:50 MDT 2014" from php if I do echo time(); from both I get 1410190731 within 20seconds of each other. but if I do strtotime('Sep 8 2014 08:17:00:153AM'); on both boxes I get 1410185820 on CentOS and 1410164220 on RHEL7 What could cause such a time difference on strtotime() and how can I fix it? Thanks!

Ubuntu to RHEL C++ cross-compilation (64bits)
|
Not exactly sure where this question belongs, let me know if I should move it. Here is the issue; over the past years I have a put together a relatively large personal codebase in C++11 that I'm using for work, but my workplace runs supposedly the latest version of RHEL on their cluster, which runs gcc 4.4.7, which supports C++11 only partially. I have battled to get a decent compiler installed, but apparently there is no easy way of making this happen, so instead I am wondering whether it would be possible to cross-compile C++11 sources on my own desktop, and export the executable on the cluster at my workplace. I just don't know where to start in order to do that: Is it possible (and how) to cross-compile C++11 sources from Ubuntu to RHEL? Since I am at it, is it possible to rebuild gcc 4.8 or a suitable libstdc++ (or libc++ ) entirely from Ubuntu to an rpm package compatible with RHEL? (Note: I would preferably use clang (3.4) to compile on my desktop, but gcc (4.8) would be fine too.)

RPM spec scripting compliance and how to test it
|
I maintain some spec files for rpms on rhel5 and rhel6, but I always struggle with more complex testing within the spec file. Often I resign writing the config logic in a perl or bash script that is executed within the rpm upon installation. Now I struggle with this simple not equal test, I believed the scripting logic was close to bash, but at least some work for bash. If I remove that if test it all works. echo "verifying base:%{smm_public_base} against %{smm_public}"; # if smm_public is not the same as smm_public_base we must sublink if [ %{smm_public_base} -ne %{smm_public} ]; then echo "smm_public_base:%{smm_public_base} is not the same as smm_public:%{smm_public} so we need to soflink it" if [ -L %{smm_public_base ]; then rm -rf %{smm_public_base} fi ln -s %{smm_public} %{smm_public_base} || : fi I've tried: if [ %{smm_public_base} != %{smm_public} ]; then and if [ "%{smm_public_base}" != "%{smm_public}" ]; then Those give errors like this verifying base:/opt/s3public against /opt/app/s3public /var/tmp/rpm-tmp.29711: line 60: syntax error: unexpected end of file error: %post(secana_smm2_SEB_PROD-r250-225.x86_64) scriptlet failed, exit status 2 So I've been searching for a primer on how to write scripting logic within a spec file, but found very little except for simple testing in the Fedora RPM guide Anyone having some best practices here. Opensuse says look at a redhat package. Thanks

CVE-2011-1092 on Centos / PCI DSS compliance
|
A security scan of a client's site flagged up the fact that, since they were running PHP 5.3.3, they were vulnerable to CVE-2011-1092 (fixed in 5.3.6 and above). Normally I'd say that backporting would have dealt with this, as their PHP has been backported over the years to 5.3.27, but there's no indication in the changelog that this specific CVE has been addressed. Looking at [URL] and [URL] indicates expressly that this issue hasn't been addressed in the version of PHP shipped with RHEL and Centos, because RHEL don't think it's a security issue. That leaves the client with a dilemma - their PCI DSS compliance scanner company (Trustwave) won't accept RHEL's statement of "this is not a security issue", saying "Visiting [the RHEL page linked to above] appears to show that RedHat has not addressed CVE-2011-1092. Since this finding affects PCI DSS Compliance, it does need to be confirmed to have been addressed in some fashion." Does anyone have any suggestions how to proceed on this? Is it possible to address the issue directly by patching the files in some way? Thanks in advance, for any suggestions.

How to use an older version of glibc, for Python script to work on REHL 3, using PyInstaller on CentOS6
|
I have a RHEL3 server with Python 2.2! I need to run some scripts on that machine using 2.6 Python. So I also have a CentOS 6 with Python 2.6. I wrote the code and used PyInstaller to give me a single executable. That works on the CentOS machine. However, on the REHL3 I get this error " /lib/tls/libc.so.6: version GLIBC_2.4' not found /lib/tls/libc.so.6: version GLIBC_2.3.4' not found " Understandable, as it's old vs new. I tried using PyInstaller on CentOS 3 but there were dependencies and yum doesn't work and generally CentOS 3 is dead. I thought I could install GLIBC 2.4 and 2.3.4 on CentOS 6 in a different directory. That could work, but I wouldn't know how to use PyInstaller to use that library. Then I thought, could I chroot? What are your ideas on this, as I am out of them!

python regex doesnt match when run from cron
|
I'm having difficulty getting a regex to match when the job is run from cron. When I run it from the cmd line it works just fine. I have some output from an ssh session that I need to parse for some CPU data. parts = \x1b[7mlines 24-46 \x1b[27m\x1b[K\r\x1b[KCPU 9 parts = \x1b[7mlines 25-47 \x1b[27m\x1b[K\r\x1b[K Utilization: 57% parts = Peak Utilization Last Hour: 100% at 2014/04/09 07:07:12 parts = Avg. Utilization Last Hour: 67% parts = parts = \x1b[7mlines 48-70 \x1b[27m\x1b[K\r\x1b[K parts = \x1b[7mlines 49-71 \x1b[27m\x1b[K\r\x1b[KCPU 14 parts = Utilization: 46% The sample above just has the problem output. Call it "sshoutput" I need to remove \x1b[7mlines X-X \x1b[27m\x1b[K\r\x1b[K from an lines that contain it. This formats the output correctly for the parsing function that I made. regex used: \\x1b\[7mlines [0-9]*-[0-9]* \\x1b\[27m\\x1b\[K\\r\\x1b\[K Code that removes the problem characters: ansi_char = re.compile('\\x1b\[7mlines [0-9]*-[0-9]* \\x1b\[27m\\x1b\[K\\r\\x1b\[K') def strip_ansi(with_ansi): return ansi_char.sub('', with_ansi) strip_ansi(sshoutput.before) This is part of a larger script. When I run it from the prompt, it runs fine and creates the output with all data and correct formatting. When cron runs it, all the lines with the ansi crap dont get matched and some CPU data goes missing. The output is formatted correctly but do to some CPU lines not getting the ansi characters stripped, the data gets shifted and is incorrect. I've been researching issues with cron and environment variables. the cron locale is POSIX and mine is en_US.UTF-8. I thought maybe this had somethign to do with how the regex would be handled. there are tons of jobs in the crontab file and i cant do something globally. I did try this: */1 **** export LANG=en_US.UTF-8; /pathtomyscript/myscript.py Is there something else I could try in the crontab file, or can my regex be changed? Thanks for any help/suggestions that the community may provide. PS, im also a linux nub (RHEL 5.9) and python nub (Python 2.7). I know enough to be dangerous :)

I have some output from an ssh session that I need to parse for some CPU data. parts = \x1b[7mlines 24-46 \x1b[27m\x1b[K\r\x1b[KCPU 9 parts = \x1b[7mlines 25-47 \x1b[27m\x1b[K\r\x1b[K Utilization: 57% parts = Peak Utilization Last Hour: 100% at 2014/04/09 07:07:12 parts = Avg. Utilization Last Hour: 67% parts = parts = \x1b[7mlines 48-70 \x1b[27m\x1b[K\r\x1b[K parts = \x1b[7mlines 49-71 \x1b[27m\x1b[K\r\x1b[KCPU 14 parts = Utilization: 46% The sample above just has the problem output. Call it "sshoutput" I need to remove \x1b[7mlines X-X \x1b[27m\x1b[K\r\x1b[K from an lines that contain it. This formats the output correctly for the parsing function that I made. regex used: \\x1b\[7mlines [0-9]*-[0-9]* \\x1b\[27m\\x1b\[K\\r\\x1b\[K Code that removes the problem characters: ansi_char = re.compile('\\x1b\[7mlines [0-9]*-[0-9]* \\x1b\[27m\\x1b\[K\\r\\x1b\[K') def strip_ansi(with_ansi): return ansi_char.sub('', with_ansi) strip_ansi(sshoutput.before) This is part of a larger script. When I run it from the prompt, it runs fine and creates the output with all data and correct formatting. When cron runs it, all the lines with the ansi crap dont get matched and some CPU data goes missing. The output is formatted correctly but do to some CPU lines not getting the ansi characters stripped, the data gets shifted and is incorrect. I've been researching issues with cron and environment variables. the cron locale is POSIX and mine is en_US.UTF-8. I thought maybe this had somethign to do with how the regex would be handled. there are tons of jobs in the crontab file and i cant do something globally. I did try this: */1 **** export LANG=en_US.UTF-8; /pathtomyscript/myscript.py Is there something else I could try in the crontab file, or can my regex be changed? Thanks for any help/suggestions that the community may provide. PS, im also a linux nub (RHEL 5.9) and python nub (Python 2.7). I know enough to be dangerous :)

What is the largest buffer size for ioctl?
|
I am using ioctl() to read data from a block device (scsi.) I have noticed that when I read 1024 sectors, ioctl finishes without a problem. When I read 2048 , after a few long moments it returns ENOMEM ( errno=12 ) which is not even listed on the list of possible errors (see [URL] ) I have tripple checked that I am passing proper buffer size, so this cannot be the case - no buffer overrun. How can I learn the largest buffer size to be read using ioctl then? Edit 1 Some additional information may become helpful: Enterprise Linux Enterprise Linux Server release 5.3 (Carthage) Red Hat Enterprise Linux Server release 5.3 (Tikanga) 2.6.18-128.el5

Redhat: php53-common conflicts with php-common
|
In Redhat 5.10, when I do yum update, I got php53-common conflicts with php-common. Currently, (I have cli php 5.3.3 installed) There is a solution for centos: [URL] , but I am not sure I can use it in redhat. I did a yum update --skip-broken , but still no help. Update : A non-working-for-me-solution : [URL] Update 1 : I try to remove php53-common, then many dependent php53 packages (e.g. php53-cli, php53-bcmath, etc) will be removed as well. Do I need to install php-cli, php-bcmath, etc individually?

Cloudstack:KVM:: Snapshot stuck in Creating Status forever.

Everytime I try to chown a file from root it will be nobody:nobody on the nfs server. It's working as root but it's not working with anything else. I'm on Red Hat Enterprise Linux 6.4. I use these settings in /etc/exports (This server is on internal network only) /storage *(rw,async,no_all_squash,no_root_squash,anonuid=99,anongid=99) Can you help me? I alredy spend a complete day to try fix it. Best Wishes, Thomas

JBoss 5.1 - TopicConnection.createTopicSession hangs sometimes
|
TopicConnection.createTopicSession hangs sometimes in one env and it is working fine in another env. Env: JBoss5.1, jdk1.6.0_45, RHEL 5.8, Dell VM-ware The below is the code. TopicConnectionFactory _factory = (TopicConnectionFactory)context.lookup("java:JmsXA"); TopicConnection _connection = _factory.createTopicConnection(); TopicSession _session = _connection.createTopicSession(false, 1); --This is the place where it hangs. Topic _topic = (Topic)context.lookup(s); TopicPublisher _publisher = _session.createPublisher(_topic); _connection.start(); I feel that it could be some server configuration related issue. Kindly provide your suggestion.

Spool to CSV with SQL*Plus and then convert the CSV to PDF
|
I have a SQL that spools some results to a CSV file which then gets e-mailed out to customers. The way that Microsoft Excel (usually the end users default application for opening CSV files) is slightly confusing for some end users in that the columns usually need to be made larger (otherwise #'s are shown etc.) before it can be printed. Is it possible to spool straight to a PDF file, or to convert the CSV to an easier to read PDF before e-mailing out? I searched online for a command-line tool to convert a CSV to a PDF but come up blank. This is generated on a Red Hat Enterprise Linux server without a RHN subscription so something with a lot of dependencies would be a nightmare to install.

PHP - is this PHP or CentOS, Red hat enterprise linux bug? When doing php://output it fails to output under Red hat linux but works in other OS

I have this excel file creator libraries ( [URL] ) which is working in my Ubuntu to make xlsx files. But when putting this working version, in main server ( CentOS and RHEL 6.4 ) cause the file not to be shown via $objWriter->save('php://output'); and also do not throw any error in log files. Simply fails to create the file and dump in the browser. (trying under ZF1 , PHP5) $objPHPExcel = new PHPExcel(); ..... $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); ob_end_clean(); $objWriter->save('php://output');

ssh2 not working for suse
|
I am trying to ssh from RHEL to SLES machine. I am using PHP function ssh2 to achieve that. Authentication is not happening even after passing correct username and password. But the same code is working fine for RHEL->RHEL. I am able to ssh to the SLES machine from RHEL terminal. But using ssh2 it is not happening. <?php if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist"); // log in at ip on port 22 if(!($con = ssh2_connect(ip, 22))){ echo "fail: unable to establish connection\n"; } else { // try to authenticate with username root, password password if(!ssh2_auth_password($con, "root", "password")) { echo "fail: unable to authenticate\n"; } else { // allright, we're in! echo "okay: logged in...\n"; // execute a command if (!($stream = ssh2_exec($con, 'date' ))) { echo "fail: unable to execute command\n"; } else { // collect returning data from command //echo "in else"; stream_set_blocking($stream, true); $data = ""; while ($buf = fread($stream,4096)) { $data .= $buf; } echo $data; fclose($stream); } } } ?> I am getting the output "fail:unable to authenticate". Why is it happening that way? Any solution to it?

Possible to create a single source RPM which is compatible with RHEL5 and RHEL6?
|
I need to create a single source RPM which can be used on both RHEL5 and RHEL6 OSes. Starting with RHEL6, Redhat switched to sha256 for the checksum. I know that I can create a rpm using either sha1 or sha256 but there is no way for rpm on either release to select a checksum algo. AFAIK, one can't even tell rpm to ignore the checksum. So, is it possible to create a single RPM which is usable on both RHEL5 and RHEL6, and use the stock rpm command (ie, I don't want to have to use cpio to extract).

Curl and Browser are serving different versions of file
|
I have a wsdl(essentially an xml) file on the server. Now when i access this file from the browser I get the latest version however when i use curl or wget to get this file i get a version which is older. Another interesting thing which happens is that even on deleting the file the curl is still able to get the file but the browser correctly gets a 404. I am not sure why this is happening when the protocol to get the file in both the cases is http and i see the request coming correctly in the apache access logs. However the file being served in both the cases are different. I am using apache webserver on a RHEL machine. Any pointers why this could happen.

HP-UX and RHEL ping difference
|
I have these two commands for different environments.. for HP-UX: "ping someaddress 10" for RHEL: "ping someaddress -c 10" Im Porting an application from HP-UX to RHEL and i cant tell if these two commands have same results since, I dont have a HP-UX system. I have read the HP-UX manual ( [URL] ) but still it doesn't help since no options were specified in the command. Any idea?

Curl error 77 on 64bit machine

When I run a 32-bit binary on 64-bit RHEL6.2, I get the following output from Curl with return value 0f 77, * About to connect() to 10.30.10.164 port 443 (#0) * Trying 10.30.10.164... * connected * Connected to 10.30.10.164 (10.30.10.164) port 443 (#0) * Initializing NSS with certpath: /etc/pki/nssdb * Unable to initialize NSS database * NSS error -5977 * Closing connection #0 * Problem with the SSL CA cert (path? access rights?) I did a little research and found that nss library has problems . My requirement is to run a 32bit binary on 64-bit machine that uses libcurl dynamic library. Anybody has any workaround to achieve this on RHEL 6.2 x64 machine? I can provide more details on request.. Language : C Platform : Linux (RHEL 6.2 x64) Thanx in advance :)

rpmbuild differences in RHEL 5.7 and RHEL 6.1
|
I'm trying to build an RPM using rpmbuild, which would work for both RHEL 5.7 machines and RHEL 6.1 machines, and I'm having some trouble understanding how to structure my rpmbuild/SOURCE directory. According to what I understood, if my package name is XXX, than I need to prepare rpmbuild/SOURCE/XXX.tar.gz, a tarball which contains: 1. A directory named XXX; 2. In it, all the directories and files I'm installing should be ordered as if their paths are relative to the root directory (i.e. /) For instance, if I want to install a file called foo.sh to /tmp/XXXdir/, I need to have rpmbuild/SOURCE/XXX.tar.gz contain XXX/tpm/xxxdir/foo.sh This is what I understood and this is what works when I install my RPM on my RHEL 5.7 machine (i.e. in the example above the file is installaed to /tmp/XXXdir/foo.sh). However, on an RHEL 6.1 machine I get the undesired behaviour of having my files installed to a newly created /XXX directory, and from there I get the same tree structure I wanted for / (i.e. in the example above I get the file at /XXX/tmp/XXXdir/foo.sh). Any idea why this happenes? Perhaps I've got it wrong and my rpmbuild/SOURCE structure is not as it should be? Any insights would be very helpful. Thanks a lot in advance, Lior

How to cheat *.so library into using missing @GLIBC_2.6 function?
|
I need to run relatively new package on not-so-new RHEL 5.6. I have 3rd party library ( lib3rdparty.so ) which is compiled against glibc 2.6 while RHEL 5.6 have only 2.5 installed. But in the library there is only a couple of references to sched_getcpu@@GLIBC_2.6 . I've checked it like this readelf -s lib3rdparty.so | egrep "@GLIBC_2.[6-9]" to find references to something newer than GLIBC_2.5 which is installed. The output is 0 FUNC GLOBAL DEFAULT UND sched_getcpu@GLIBC_2.6 (62) 0 FUNC GLOBAL DEFAULT UND sched_getcpu@@GLIBC_2.6 So, I have only one function from GLIBC_2.6 . Now I want to make library think, that I have this function. For that purpose I forged small library ( libcheat.so ) like it mentioned here . Now I have libcheat.so file which, if run through readelf , will show this string: 10 FUNC GLOBAL DEFAULT 11 sched_getcpu@@GLIBC_2.6 With this library I managed to succesfully build executable which is dynamically linked with lib3rdparty.so . Without this library I can't build anything, because ld can't find reference to sched_getcpu . But the problem is with running this file: when I try to run it I have a following error: ./hello_world: version `GLIBC_2.6' not found (required by ./lib3rdparty.so) So, I believe there is one last step to make it work, but I don't know what to do. I've tried to use /etc/ld.conf.preload and exporting LD_LIBRARY_PATH so it would point to my library to load before others. But it won't run. Tried to run it through strace but have no meaningful output. Any ideas?

Will app built with gcc 4.x on CentOS/RHEL 4.8 run on completely un-updated CentOS/RHEL 4?
|
We have a commercial application that we build on 32-bit CentOS 4.8 (equivalent to Red Hat Enterprise Linux (RHEL) 4 update 8. The default gcc compiler is at 3.4.6 We are able to run our binary on both 32- and 64-bit CentOS/RHEL 4 and 5 including completely un-updated RHEL 4. THE QUESTION: If we update to a newer gcc 4 version, will the binary still run on a completely un-updated RHEL 4 The newest gcc appears to be 4.5.1 and 4.4.5 (And yes there are customers who install the intial version, run on an isolated network with no Internet access, and NEVER update from the as-shipped version.) This issue has arisen because we are now porting to 64-bit FreeBSD 8.1 for amd64 and the default gcc there is gcc 4.2.1

The default gcc compiler is at 3.4.6 We are able to run our binary on both 32- and 64-bit CentOS/RHEL 4 and 5 including completely un-updated RHEL 4. THE QUESTION: If we update to a newer gcc 4 version, will the binary still run on a completely un-updated RHEL 4 The newest gcc appears to be 4.5.1 and 4.4.5 (And yes there are customers who install the intial version, run on an isolated network with no Internet access, and NEVER update from the as-shipped version.) This issue has arisen because we are now porting to 64-bit FreeBSD 8.1 for amd64 and the default gcc there is gcc 4.2.1

`df' unexpected' checking for diskspace inside a function using a while loop bash script
|
I am getting an issue where if I call this function below, I get the error line 89: syntax error at line 117: 'df' unexpected . If I take the code out of the function it works fine. Is there any reason for the error above? This is a bash script on RHEL. function testr{ df -H | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while read output; do usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1) partition=$(echo $output | awk '{ print $2 }') (.. Sends alert via mail after) done }

cx_Oracle.DatabaseError: ORA-12592: TNS:bad packet
|
I am writing a Flask API, and am seeing a lot of failures when load testing. Looking at the uwsgi logs, I am seeing something which looks a little nasty, which is: cx_Oracle.DatabaseError: ORA-12592: TNS:bad packet The oracle connection is working, as I am not seeing a complete failure, but this does seem to be what is terminating the http rest call prematurely in most cases. What is causing this? I am using RHEL, with cx_Oracle 7.23, connecting to 12C database. I am using the Oracle thin client. Exception on /api/read/maa [GET] Traceback (most recent call last): File "/ariel/anaconda3/lib/python3.7/site-packages/flask/app.py", line 2447, in wsgi_app response = self.full_dispatch_request() File "/ariel/anaconda3/lib/python3.7/site-packages/flask/app.py", line 1952, in full_dispatch_request rv = self.handle_user_exception(e) File "/ariel/anaconda3/lib/python3.7/site-packages/flask/app.py", line 1821, in handle_user_exception reraise(exc_type, exc_value, tb) File "/ariel/anaconda3/lib/python3.7/site-packages/flask/_compat.py", line 39, in reraise raise value File "/ariel/anaconda3/lib/python3.7/site-packages/flask/app.py", line 1950, in full_dispatch_request rv = self.dispatch_request() File "/ariel/anaconda3/lib/python3.7/site-packages/flask/app.py", line 1936, in dispatch_request return self.view_functions[rule.endpoint](**req.view_args) File "/ariel/anaconda3/lib/python3.7/site-packages/connexion/decorators/decorator.py", line 48, in wrapper response = function(request) File "/ariel/anaconda3/lib/python3.7/site-packages/connexion/decorators/uri_parsing.py", line 144, in wrapper response = function(request) File "/ariel/anaconda3/lib/python3.7/site-packages/connexion/decorators/validation.py", line 384, in wrapper return function(request) File "/ariel/anaconda3/lib/python3.7/site-packages/connexion/decorators/parameter.py", line 121, in wrapper return function(**kwargs) File "./registrations.py", line 58, in read_maa_non_passive for row in cursor_ariel.fetchall(): cx_Oracle.DatabaseError: ORA-12592: TNS:bad packet Getting data and status code ----UPDATE--------- All my problems went away when I stopped connection pooling in cx_Oracle. I originally had a single connection to oracle shared across the Flask application. This have me failures in stress testing. So I tried to be clever and use SessionPooling and acquire connections and release them at each service call. Finally I went back to "bad practice" and create a completely new connection to Oracle for every single function call (api endpoint), and I now get 100% success rate across stress testing in Locust, even for the larger response calls which are 30mb json payloads.
