# Simple Syslog Server
Basic syslog server written in Java. All received messages are written to *stdout* or optionally forwarded to another syslog server.
All received messages are written to *stdout* and optionally forwarded to another syslog server.
The syslog server is able to listen on UDP and/or TCP and parses syslog messages in either RFC5424 or RFC3164 (BSD) format.
The default syslog port (514) requires you to run syslogd as root / administrator.
If you do not wish to do so, you can choose a port number (with the -p flag) above 1024.
If you do not wish to do so, you can choose a port number (with the *-p* or *--port* flag) above 1024.

### Examples
Listening on a non-standard syslog port:
```
java -jar /path/to/syslogd-x.y.z-all.jar --port 1514
```
or, if installed as a *deb* or *rpm* package:
```
/opt/syslogd/bin/syslogd --port 1514
```
Listening on the standard syslog port (requires root privileges) and forwarding messages on to another log-system on a non-standard port.
```
java -jar /path/to/syslogd-x.y.z-all.jar --forward remotehost:1514
```
If you don't want any output locally (only forwarding), you can use the ```--no-stdout``` flag.
## Notes
Syslog messages from AIX (and IBM Power Virtual I/O Servers) can be troublesome with some logging solutions. These can be received with
syslogd and optionally forwarded on to Graylog, Splunk or other logging solutions.
