Ho to use tcpdump

Jojo Castro — Thu, 21 May 2009 04:28:17 GMT

Hi all,

We are currently some link problem between our front end connecting to our host via port.

Here is the set-up

10.144.10.134 – connects to 10.121.55.76:21920 and 10.121.55.79:21920

10.144.10.152 – connects to 10.121.55.76:21921 and 10.121.55.79:21921

10.144.10.181 – connects to 10.121.55.76:21922 and 10.121.55.79:20922

For example i want to see the status of 10.144.10.134 connection to 10.121.55.76 using port 21920, how does tcpdump helps?

What is the syntax?

Thanks!
