Rather than get snort to do the redirection, why not have snort log to the local
syslogd (via normal unix sockets instead of IP sockets) and have syslog.conf
redirect the messages to a separate box?
(syslogd can do this easily.. instead of specifying an output file for the
messages you specify @192.168.40.104)
IMO this really the way it should be done anyway. Centralized logging control is
much more flexible than per-application logging control.
You also get the option of logging a duplicate copy locally, should you desire
to do so.
