What terminal-based network speed tests are available?

I'm looking to find a way to test my internet speed at home through ssh. Does anyone know a terminal app that can give me calculations similar info to speedtest.net?

It would also be really cool if there was something that would do tests based on common internet ports too (i.e. web, torrent, etc) so you can see if you're getting throttled by your ISP.

You may use nload (Install nload) for this purpose. Sample output:

You can install nload by this command:

sudo apt-get install nload

Also available in software center.

Update Nov 2016: I discontinued it. Please use another provider i.e. Init7 with http://speedtest.init7.net/10GB.dat

Original answer:

There is also this easy "speedtest":

wget -O/dev/null speedtest.pixelwolf.ch

This gives you the current speed and it is available up to 100 megabits per second.
