Since I've experienced the same problem and there was no
response to Peter, I'm trying a repost. Tethereal with the
-a duration: parameter doesn't exit until it captures a
filtered packet. If it did exit, it would be more convenient
than using tcpdump, sleep and pkill to scan ports. Ethereal
does exit even if it doesn't capture a filtered packet when
using "Stop capture after ... seconds." Is there a reason
why the two programs don't function the same way?
Thanks
