Hello,
If does but then you require X to be running or at least installed on the box you are running ethereal on.
Which I find usually is not the case, if you want to capture local packets you can start up Ethereal, click on start capture and at in / create some filters and then start capturing.
But again ... only works if X is running or installed on the machine. I say installed because you could use XForwarding and run Ethereal on a remote host.
Any ways a lot firewall boxs and routers do not have X.

Hello,
Well for example if you wanted to monitor the traffic on a Linux box (router maybe) I would use tcpdump and then use ethereal to view the traffic.
tcpdump -n -i eth0 -w /tmp/testfile -s 9999 port 110 and host X.X.X.X
-n - do not try and resolve the domain name -i - interface -w - write data to file -s - snap length (length of packet to capture)

Quick question,
How can I use ethereal, or a similar tool to capture pop and smtp traffic going into and out of a specific domain on the internet?
Thanks,
Jesse
