Monitor a socket port

[John J. Hughes II]

Is there a way to monitor the amount of data that is sent/received over one
port on a socket? I don't care about the data just the number of bytes.

Depends.
If you want to monitor port over which you are sending / receiving data ,
it's relatively simple. Just count bytes.

If you want monitor port connected with other process you can google about
WinpCap
It comes with handy documentation.

AFAIK to know this you have to write unmanaged software called LSP ( Layered Service Provider ) that will collect traffic data for specific port. LSP is only for sockets, if you want all data from non-socket communications you have to use/write kernel-mode driver.

Well I wrote the program so in concept yes I can just count bytes. The
problem is I start a thread for each socket handle on the port and would
like the cumulative count port rather then the count for the handle on one
thread. I was sort of hoping for an overload of the byte received/sent for
the port.

Thanks for the program name.

Thanks, that gives me a start. I was hoping for something from .NET but the
trace function seems more decated to getting the data then the count of
bytes.

If i were you i'd try with WinPcap.
It's necesesary thing for many port sniffers ( f.e: Ethereal ), that obrain
many data from the ports.
