Jeffs,

The pcap_log plugin might be what you're looking for.  It lets you
save traffic to a pcap file using BPF syntax for filtering.  The
filter option must be enclosed in quotes if it contains a space.
Here's a simple example:

msf > load pcap_log
[-] No interface given
usage: load pcap_log iface=<iface> [path=<logpath>]
[prefix=<logprefix>] [filter="<filter>"]
[-] Failed to load plugin from
/home/egypt/svn/framework3/trunk/plugins/pcap_log: No interface
specified
msf > load pcap_log iface=eth1 filter="host 192.168.1.1"
[*] Logs in /tmp/msf3-session_2009-04-07_00-14-03.pcap
[*] Starting capture thread on interface eth1
[*] Successfully loaded plugin: pcap_log

Hope this helped,
egypt

Got it.

I see now that the filter uses Berkeley packet filtering syntax.? Good.? Is
the screen output saved anywhere for later use or is it just existing for
the session on the screen.? Can it be dumped do you think?

Thanks.

It seems to sniff http by default and I'm having difficulty killing
it.  Keeps saying type exit to exit but there is no prompt and I have
to either ctr-c kill it with many attempts or kill -9 it.

What is the syntax for filtering?  Anything I put in there just seems
to default to sniffing http traffic...


The kill bug is something we should look into; there are a few other
cases where that happens and its really annoying. The test/capture
module just sniffs http, thats it, its meant be an example you can
customize and not necessarily a useful module on its own.
