I've just released a GPL tool that allows you to capture and view the
log files generated by the linksys BEFSR family of routers/firewalls
on Linux. I did a google groups search and saw a couple of people on
this group looking for such a tool so I thought I'd let you all know
it exits.
You can find it at
http://link-n-log.sourceforge.net/
It captures all the alerts to a database and then allows you to view
and sort them. You can also do DNS lookups on any host in the logs
and do port lookups on any port. Hope somebody finds it useful.
