You can also use cbq. But htb is easier to configure. Or go for the 2.4.20
kernel. That has htb support.

You can configure a protected channel with a minimum bandwidth.

Have you tried screen? If you start screen, you get a virtual console. You
can work in it like you normally do, but if your session is terminated, you
can reconnect to the same screen session with "screen -r". Very handy if you
have a faulty connection :)
