what are your favorite network troubleshooting tools?
I thought I'd add a little data to my first response:
To watch the network in real time with syslog, which puts
messages in /var/log/router.log:
tail -f /var/log/router.log | egrep -vi 'terms|I|do|not|want|to|see|SyncConfigOK|SaveConfigSucceeded|LogFile|etcetera|etcetera'
To look for a problems on router1:
grep -i router1 /var/log/router.log | egrep -vi 'terms|I|do|not|want|to|see' | less
