[LARTC] Problems at end of slow satelite link

Newbe hoping this is the correct area to post.

I've been reading the LARTC HOWTO, but at 110 pages, I am finding it difficult to know where to start. I hope you may be able to surgest a starting place to a couple of problems I am having.

I am dealing with the slow end of a satelite ADSL. This is 'lumpy', with huge latency (1 to 30 sec), 10% dropped packets, huge but intermittent bursts of packets, and generally a pile of poo. The supplier (BT) is of course no help, so we have to live with what we have.

I have tried limiting the bandwidth with a Tocket Bucket Filter with almost no effect.

What I think I need is to agressivelly schedule SSH and Telnet before all other TCP connections. Others I don't care about. There are I see many scheduling options, can any member surgest how I might atchive this?

The second problem I have is that my connection keeps terminating (Telnet, SSH) with 'Connection closed by foreign host', with no message in logs. Always during streaming of data. Some part of the kernel is getting tired of waiting for the other end to respond, or possible a buffer overflow? Again, if any member may surgest how this can be countered with extream predudice, I would be extreamly greatful.

Regards, Ben Clewett.
