[TBD]Tips to troubleshoot tcp connection between two processes

Get which tcp connection is established

Look at server machine.

First, If you don't know which server tcp port connection is happening, then get diff of "netstat -ap" before and after connection.

So, now I know the server port number, then execute "netstat -ap | grep https" (assume https port-443 is used).

$ netstat -ap | grep https

tcp 0 0 *:https *:* LISTEN 32167/abcd

Here 32167 is Process ID.

$ ps ax | grep 32167

32167 pts/6 S 0:00 abcd
