Could you provide a usage example for iperf? Thanks.

Well, I can't use lynx to run a speed test, since I can't find any
reliable html-only speed test websites. Most of them are in flash or
java, which is annoying.

I can't use SCP since all of the computers I have access to (other
than my server) have a very much slower bandwidth, so I wouldn't be
able to truly stress test the bandwidth of my server.

I can't use iperf since that requires a server (faster than mine)
running an iperf server.

I am still pretty stuck on this. Can anyone provide more guidance?
Thanks for the help so far guys.

Install a bittorrent client (rTorrent is very good). Get a popular
linux ISO torrent, or a OpenOffice torrent or something. Open that in
the client, then see what the download speed maxes out to.

Or just wget a large iso, like a Debian DVD or something. But I think
bittorrent would be better because you're not relying on one single
pipe to test your bandwidth (like a ftp/http transfer would use),
you're using many connections.

This covers the download bandwidth test, but I'm interested in testing
upstream as well. I haven't heard any decent solutions to testing
upstream bandwidth.

Maybe this will do:

Except that some ISP's throttle bittorrent downloads assuming they're
illegal music or video transfers.

A fair fight is the result of poor planning.

True, if you have residential or non-dedicated business broadband. Not
true, if your paying for full on dedicated bandwidth. Of course it would
depend on your Service Level Agreement.
