There is one really good command in Linux/UNIX called man :-)

man tcpdump

.....
Under Linux:
You must be root or tcpdump must be installed setuid to root
(unless your distribution has a kernel that supports capability
bits such as CAP_NET_RAW and code to allow those capability
bits to be given to particular accounts and to cause those bits
to be set on a user\u2019s initial processes when
they log in, in
which case you must have CAP_NET_RAW in order to capture and
CAP_NET_ADMIN to enumerate network devices with, for example,
the -D flag).
............

i was doing it as "aaron", after su'ing to root, tcpdump works "tcpdump: listening on eth0". i added /usr/sbin/ to my "aaron" path, and now when i run tcpdump it says "tcpdump: no suitable device found" any ideas?

also, is there a nicer graphical sniffer built-into redhat? if not perhaps someone can suggest the best and newest one to download with the most possible decodes for protocols such as h.323 and sip for VoIP

thanks
Aaron

yum install tcpdump

Or he can install it from the CD.... Though there is one question:
Aaron, are you doing it as root, or as a user? I ask that, because users
are frequently set up without /sbin and /usr/sbin in their path.

mark

Of course if you have yum configured.

i type tcpdump and it says "bash: tcpdump: command not found" where
would i go to execute it? also where should i go to check if ethereal

Ethereal might have been in that version as well. I would have to look.
