Try looking at iptraf (net-analyzer/iptraf). It's a curses based interface to watch your network interfaces. The traffic monitor will show traffic flow for each different connection, and the interface statistics will show how much total traffic is going in and out on each interface, including real-time kb/sec data. As long as you keep track of what IPs your torture streams are on, you should be able to see how each stream is going. -- Eric Bliss systems design and integration, CreativeCow.Net -- gentoo-user@gentoo.org mailing list
