Dear All<br>
I have put tcpdump trace on port 4957 on my CentOS server , as the following :<br>
#tcpdump port 4957<br>
I want to obtain the payload data to see what is realy being exchanged between my CentOS server and the outside network element . Can you please let me know how I can modify my command ?<br>
Thank you<br><div class="hm">
