One more suggestion; if I understand correctly, you want to tail -f a logfile,
but you only want to see certain events; perhaps this is what you need:
tail -f /path/to/some/logfile | grep certain_event

Thanks for email. Actually, I want to be able to see the message in context of
whats around it as I am still learning about iptables and /var/log/messages. I
tried a grep and it was even harder to see if anything was happening as I could
do an action which I knew would leave a message right then and there.
To be honest, now that I found out that the problem with ssh from F16 to Cygwin
was POM on the Windows side (and notice I am not limiting to just Cygwin
(smile)), it has become "not so important". But some of the suggestions look
worth looking at as I've wanted a way to get debug messages out of iptables into
a file other than /var/log/messages as I try to learn more about usign iptables.
From part of my firewall startup, a few LOG calls wehich might help.
# LOG and REJECT anything which looks like a probe
iptables -N PROBE
iptables -A PROBE -j LOG --log-level debug --log-prefix PROBE:
iptables -A PROBE -j REJECT --reject-with icmp-host-unreachable
