Oops... One More Time...
Ralf,
I reviewed the setup on the Linksys and it looks like it's still right.
I ran "tcpdump -X proto 2" as root for about 2 minutes today and
produced a 76 Kb text file. (The same command on a RH8 box here produced
nothing in and hour.)
I'm sure that the list doesn't need the full text of the tcpdump, but
I'll include a snip at the end of this message. If anybody wants to look
at the file, I'd be happy to e-mail it privately.
(BTW, man -t tcpdump > tcpdump.ps makes a 17 page (paper) document that
should keep me busy for days.<g>)
Thanks for your help,
Cliff
sorry for the e-mail word wrap.
