Which site is a port connected to ?

[Craig Lister]

Is it at all possible to monitor a port, and when there is a connection made
to a remote server by some other 3rd party app, my app could report that the
socket is connected, and can report the IP address that the port is
connected to ?

That's the dirty way of doing it, but I guess I can pipe the output to a
file, and then do some work on the file to achieve the desired outcome. But
... how do I execute a dos command from c#? (Basic question.. I know...)

using System.Diagnostics;

....

Process p = new Process();

p.StartInfo.FileName = "netstat";
p.StartInfo.Arguments = "-a";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.Start();

string output = p.StandardOutput.ReadToEnd();

// do something with output.

Thank you very much for that!

Is it possible to hide the DOS PROMPT window that pops up ?

Try
p.StartInvo.CreateNoWindow = false;

Can't recall if that works for the console or not, but its worth a shot. <na*******@gmail.com> wrote in message

Thanks for that!

p.StartInfo.CreateNoWindow = true;

worked like a charm!
