WAN testing with Windows Server 2003

Howdy all,

am trying to run a WAN testing tool (in this case ScriptLogic's TrafficJam, but have seem a similar issue with Solarwinds WAN Killer) which floods a link using either TCP or UDP ports (7 or 9, depending on whether you want one-way or two way traffic.

Issue is, i can't get a Windows host (XP or Server 2003) to respond to TCP 7 - i get errors that the remote host has forcibly disconnected..

I have installed Simple TCP Services in Windows, and also tried running TTCP.exe as well as the non-M$ PCATTCP - both give me BIND errors that the Protocal Family is not suported.

Has anyone every done this? or any known working alternatives?  Am basically testing a QoS implementation, so the idea is i want to flood the link with simple traffic, and then make sure our VoIP etc still still working.

Kudos and 500 points...

The echo server might simply not be implemented on windows.

But for flooding a link you don't need to have the system accept a link just to send a lot of packets.
But flooding is only a small portion of issues with VOIP, packet loss is a different one.

I don't know TrafficJam but this is possibly another tool that can help.

Cheers Noci, will give that tool a go.

Simple TCP Services in Windows is supposed to include Echo

wanem wasn't immediately useful as it's a linux tool and i was looking for a Windows one, but it did lead me to iPerf, which kinda did the trick. Of course, once you start putting WAN accelerators in the way, it all gets a little bit trickier (it told me i was getting 88Mbs our of a 4Mbs link...)
