capturing network transaction, open source
 

Hi group,

I know what I am looking for but don't know what to call it.
I want an open source solution that will allow me to capture
traffic to a print server and save it in separate files. I
picture a SBC ( Raspberry Pi 2 ). TCPdump does not look like
the answer?

Anybody know what I can use?

Thanks for your time.

tcpdump (and wireshark) are specifically for capturing network traffic packets. It has many flags so you can get as much or as little as you want.

Is your question really about network traffic or are you trying to capture what is actually being printed? If it is the latter tcpdump is probably not the best tool.

Yes, I am attempting to capture what is being printed. I could write a simple network proxy tool, but I would like to use something that is Open Source just for the support issues.
