1.) It uses either TCP or UDP (you get to choose) so as long as the network can route standard IP traffic, it will work. On the server, do `iperf -s`. On the client, do `iperf -c WWW.XXX.YYY.ZZZ` (where WWW.XXX.YYY.ZZZ is the server's IP). `iperf --help` gives you all the options. 2.) Depend

Re: [Iperf-users] Help understanding results from a single TCP session

You were getting more bandwidth than expected because Linux (and other OSes) will automatically increase the TCP window size. Google for tcp_moderate_rcvbuf, for example. One way to actually get the window sizes you expect is to use the -w argument to iperf. Note that linux will double what you

You need a scope ID for IPv6 link local addresses. Something like "fe80::216:17ff:feba:59e0%eth1". Iperf might be able to grok scope IDs, or not. If not, use any address but link local. Cheers, Marc 2009/6/19 senthil kumar > > Hi, > > I want the exact command for generating UDP/IPv6, TCP/IPv6
