I've written an extension to systat that allows you to monitor the
traffic through active network interfaces on the system, akin to
netstat -I. I've attached the patch to this e-mail, but it can also be
found at http://arpa.com/~trent/systat-ifstat-current.patch[.tar.gz].
All comments on code, style or functionality are welcome.
Regards,
Trent.
