I don't think you can send directly to native syslog protocol. However, with [syslog-ng][1] you can read (and forward) from various sources. I would try to use the `network()`, i.e. tcp source and then simply try `UTL_TCP.WRITE_LINE()` function.
Most likely it will work better with `no-parse` option. Then you can si... |
