Maybe you could set up TC (Linux Bandwidth Management and Traffic
Control). Should be able to allow you restrict traffic to any speed you
like.

Out of curiousity: why simulate? How difficult is it to test with a real
dial-up connection?

It's been a few years, but IIRC Shunra is rather expensive.

To save you a bit of Googling, here are a few URLs from my old
bookmarks.  I cannot recommend any of these because I have not looked at
this stuff for ages (ages in internet time, but still...). Hope this
will help you get started. I don't remember whether any of these will
let you simulate the bandwidth of a dial-up connection (I think NIST Net
does). They may let you play with latency, packet loss, maybe jitter (I
doubt the latter). Some of them may have a different purpose, e.g.
protocol debugging, and will not be suitable. I don't remember which is
which, though I suspect NIST Net is closer to what you need than the
others.
