Hi hpchong7,

in /etc/syslog.conf file of machine A, comment all lines and all these two lines

*.*    @IP_ADDRESS_OF_B
*.*    @IP_ADDRESS_OF_C

This will cause the log messages at A to be sent to B and C ... No messages would be recoreded at A .. If you want to store messages on A too, then do not comment out the existing lines... just add the above two lines

restart syslogd on all three machines with -r option

/etc/init.d/syslog stop
/sbin/syslogd -r
/sbin/klogd

Cheers!

try to look for
syslog-ng (http://www.balabit.hu/products/syslog-ng/)
Also look at nsyslogd too(http://coombs.anu.edu.au/~avalon/nsyslog.html
on your logging system
============================
Logging to network is done like this.
On remote machine run syslog with option -r to make it listen for messages incomming from network. Make sure that /etc/services on both machines contains entry for syslog's port. It should look like this:

syslog     514/udp

Then replace syslog.conf on local machine with one looking like this:

*.*     @remote

This will instruct local syslog to send all logs to syslog on remote.

On remote machine setup your syslog.conf in the way you like.
(all logs in one file, or separate files for mail, warn, kern...).

And read 'man syslog' again

In this case it's not necessary to look for any alternative syslog programs. The standard syslog that comes with pretty much any Linux distribution is more than capable of supporting this use case.
