Using packet sniffer and sending it a server that is listening on ETH0

RouterOS General

Hey guys, I am using the Mikrotik Packet sniffer and I aim it towards a Centos server that is running tcpdump on the interface and listening on 37008. Everything is capturing just fine but when I open the pcap file on my desktop to analyze it, every packet is in UDP format. Is there a way to have the actual protocols of the packets?


Thanks,
Bumbaa

Yes, you need a special tool that you run on the server to unpack those UDP packets.
It is called trafr and can be found on the software download page.

I get this error while trying to run it

./trafr

./trafr: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

Anyhow, thanks I’ll look into it.

You probably need to install some extra package e.g. 32-bit C library.
