Hi, i want to filter by spesific protocols our network. How can i do this?

Can you be more specific?

In general, you can use BPF to filter packets.

yes, now I want to filter our network traffic for SMPP, I'm doing research this for two days but I can not find anything about it.

Can you give some pcap file example?

I don't know SMPP so well, if it is on specific ports, for example, you can just filter these ports.

SMPP pcap file example is here, and SMPP dont have spesific ports so i cant filter ports.

It seems that SMPP is recognized by a specified port (even if it's not globally known).


As it says in the Wireshark page:

You cannot directly filter SMPP protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.


I don't know this protocol well, if you know it better and know how to recognize whether a packet is SMPP or not, we can figure out how to do it in Pcap.Net.

I don't know how Wireshark filters SMPP in the display filter, maybe you can find out how Wireshark does it.
