OK, I have traffic logs and alerts working now - here are the current
findings:
1) Steve's suggestion below ("set firewall log-self") may have been
the turning point, surely it's good to see what packets were dropped
whose destination address was the firewall itself, in any case.
2) The Netscreen is now sending logs. There are 2 significant
revelations:
A) The documentation says it will send traffic logs every 24 hours,
or when the log fills up. As it turns out, it does *not* send logs
every 24 hours, I have only seen them when the log fills up. (all
this is under ScreenOS 3.03r3)
B) The Netscreen buffers alarms for 10 minutes, ie if you get a new
alarm 2 minutes after the first, it will buffer that alarm and send
it with a batch 10 minutes after the last alarm. (this is not in the
documentation)
3) It's critical that you have a manually-entered static-route for
any host or network that you plan to send management traffic either
to or from the Netscreen, EVEN IF this host or network is connected
directly to one of the Netscreen's interfaces. (however this was not
my current problem, it had already been done on this box)
I don't know why Bruce gets traffic reports but no alarms. My only
guess is either A) he doesn't have a proper policy setup with alarms
enabled. (or it's configured but all relevant traffic is matching a
policy 'higher up' in the list and never becoming associated with the
policy which has alarms configured) or B) the configuration command
"set admin mail alert" has not been set.
I hope the summary above comes in handy for some of you, and thanks
for all your suggestions.
Phil
