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.

Michael.
