tcpdump host <IP-addr-deb-server> and port 4957
This will grab all packets to and from the server, which are to or
from port 4957
If you want traffic in one direction only, you can use "src host" or
"dst host" instead of "host", and/or
"src port" or "dst port" instaed of "port".
You could add -s 0 to ensure you grab entire packets regardless of
size, and -v, -vv or -vvv if you need more details on packets.
