Re: my traffic not captured

Ohhh, I see what I did. It was a network byte-ordering problem. I wanted it to connect to port 2022 (07e6 hex), but it was switching the bytes around such that I was actually connecting to port 58887 (e607 hex). My eye had been skipping right past the captured packets because I assumed they were for some other protocol!

Thanks for you the help, Guy and Anne.

(I am relatively new to using email lists such as this- will Anne also get this message, or do I have to reply specifically to her email in order for her to see it?)

I am writing a program that makes use of Windows Sockets, and I thought I might use Wireshark to watch the traffic go back and forth across my network. However, the Shark doesn't seem to capture the packets generated by my program. I send data from the client computer to the server computer using a regular TCP connection onto port 2022 of the server. I know the server is receiving the information, because it is able to print it on the screen. Wireshark seems to be capturing other data just fine, such as HTTP traffic on port 80, and VNC traffic (I use that to fiddle with my server so I don't have to walk back and forth between my computers).

Is it capturing other traffic *between the client and server in question*?
