Re: [OSL | CCIE_RS] how to use iperf with GNS3
Just out of curiosity, why would you want to use iperf in GNS3? I don't think it makes a lot of sense to do 'throughput' testing on these virtual boxes :-) The throughput of a Dynamips router is very low. -- Regards, Rick Mur CCIE2 #21946 (RS / Service Provider) Sr. Support Engineer – IPexpert, Inc.

Re: [OSL | CCIE_RS] how to use iperf with GNS3
I was thinking the same thing actually... The only real reason I can think of would be to see if your QoS is doing its job and seeing via iPerf what traffic was being dropped/shaped.

Re: [OSL | CCIE_RS] how to use iperf with GNS3
I think it's to just test the technology. And to see how iperf is working ... I mean isn't that the whole point of Dynamips/GNS3? To just see if it works and learn the technology? You also do not use Dynamips or GNS3 equipment to route production traffic (just because it's possible) -- Regards, Iwan Hoogendoorn CCIE #13084 (RS / Security / SP) Sr. Support Engineer – IPexpert, Inc.

In case you do not have version 2.04 here is a reference to it: http://www.networkedmediatank.com/showthread.php?tid=8096 Did you place iperf at the root of your C: drive? go to the direcotry where you downloaded it or add it to the path.
