    Does anyone have any suggestions for software that can run on a server to
    generate network traffic to simulate a large load on switches and routers
    under test.
    Its easy enough to do this for a short period by moving files around etc but
    we could do with something that can run continually without attention.

    What OS?

    For Windows, something like "ping -t -l 8192" should get things warmed
    up; for *nix-like systems, the equivalent would be "ping -s 8192".

    HTH, and don't forget to RTFM.

    2k or 2k3
    Constant pings are ok for testing connectivity , but we could do with a lot
    more load to stress the switches a bit.

    Hehehe , nice idea ,but the switches will be on a separate network for
    testing purposes.

    I know there is software that you can buy to generate simulated traffic ,
    but a free solution would be better.
    At the mo I think a batch file to copy a bunch of files from one machine to
    another then delete them and start again is looking likely

    I've sent you an email. Forward it to everyone on the network and make sure
    they run the attachment. That should do it.

    Wack up the packet size, and run a load of them in parallel?

    :begin
    xcopy //servername/rootshare /e /q /h /y
    goto begin

    .... in a batch file should keep it busy for a while, *and* saves having
    to delete the files each time.

    Microsoft NetMon I think it was called. Comes as standard
    with something like Exchange, purely for that purpose.

    I'll have to go back through some old course notes if
    it's not right, but that sounds familiar.

    Batch file looping, copy large files backward and forward.
    No special software needed.
