Have you seen: http://wanem.sourceforge.net/ It's basically a bootable CD that can be used to emulate a wan. Various packet loss, rtt settings can be simulated. Basically boot and run. I have used iut for testing performance of a web application over lossy networks. It works well for me and means I can use any random box I have easily since I can return to normal state just by booting the box without the live cd in the drive. -- -- rouilj John Rouillard System Administrator Renesys Corporation 603-244-9084 (cell) 603-643-9300 x 111 ------------------------------------------------------------------------------ Come build with us!
