Couple things...

[Carter Bullard]

Done some testing with your argus.conf file.

Can't find any argus faults using it with your packet files,
on my machines, but there is one issue with the configuration.

Your ARGUS_MONITOR_ID is inappropriate.  You only get 32-bits
for a source id, so the max string you can use is 4 characters
long.  We'll cut it to 4 chars, so I don't think that this
will cause problems, but it is incorrect.

I’ve tried testing normal and reverse keystroke detection between hosts that were in the same data center and dnstroke and snstroke always show up as “0,0” or “,,” (the latter happens more when there are directional issues).  But if I watch a host that I ssh into over the VPN from my home connection, Argus detects keystrokes.

If it works for a slower network connection and not a faster network connection (or maybe I should say lower/higher latency connection), which configuration options should I experiment with to find the right balance?
