Yahoo Instant Messaging


DOES ANYBODY KNOW WHAT PORT NUMBERS YAHOO INSTANT MESSENGER USES AND HOW WOULD I BLOCK THESE PORTS TEMPORARILY USING IPTABLES?

ALSO WHEN I USE NETSTAT -PANTU I SEE THE FOLLOWING:

dabeast@linux:~> netstat -pantu|more
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State

hmm... maybe. I would more reliably installing ethereal and ethereal-gnome, and running a capture on all incoming/outgoing packets on the machine running yahoo messenger. Ethereal is really good about recognizing protocols, it should show you which packets are captured yahoo packets
