lsof?

[Keary Suska]

I am not familiar with "lsof", but you can use backticks:

    @array = ` lsof -i | grep <port>`;

Or open a pipe-from:

    open PIPE, "lsof -i | grep <port> |";

Beware of security problems when using these--don't pass any tainted data.
You may also want to install a signal handler for SIGPIPE, which is
triggered when you have a broken pipe. Otherwise, you really don't have any
idea if your pipe attempt failed.
