Question

Computer networks

There was a need to intercept packets of only one program. How. Wireshark to do it, or what tools to do it?

Answer 1

One program always accesses a specific host on a specific port, also from a specific host and port. Put filters on the port and address.

Answer 2

If the protocol is HTTP, then Fiddler is more convenient, and Wireshark has a lot.
