Dear All
I have put tcpdump trace on port 4957 on my CentOS server , as the following :
#tcpdump port 4957
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 ?
Thank you

Thank you
tcpdump -i ethX -p -s 0 -w /path/to/4957.trace.pcap port 4957
After finishing the trace you can load the saved pcap file into wireshark for a detailed analysis.
