rsyslog: Logging to remote server

Now that we've setup the rsyslogd server to accept incoming connections (NOTE: UDP somehow didn't work.  I had to configure rsyslogd to listen to TCP instead); we can now configure the "client" rsyslogd instance to log to a remote server.

In the "client" server, we'll need to edit the same configuration file /etc/rsyslog.conf.  I've added the highlighted lines below:

[...]
###############
#### RULES ####
###############

# Log all messages to this rsyslogd host
*.* @@myhost:514
#
# First some standard log files.  Log by facility.
#
auth,authpriv.*                 /var/log/auth.log
*.*;auth,authpriv.none          -/var/log/syslog
#cron.*                         /var/log/cron.log
[...]

The rest of the config file remains unchanged.  Reload/restart the service once we're done:

myclient:~# /etc/init.d/rsyslog reload
Reloading enhanced syslogd: rsyslogd.

We can now use the logger command to send log messages to the syslog.  Here's what I used:

# logger -t CLIENT_TEST "This is a test to test the test"

The following entry should be logged in myhost /var/log/syslog file:

Dec 12 15:17:52 myhost CLIENT_TEST: This is a test to test the test
