ssh instability

Hello.
I have a problem with ssh client:
I have a server hosted at my job, and when I connect through ssh from my job workstation, there is no problem, but when I try to connect from my home, ssh shell is not quite responsive, and sometime I lost connection.

I have a quite good bandwith at my job (600 KB/s) and at home I have a low connection cable (15 KB/s) but normally I think it should be enough.

Is somebody experienced the same problem???

thanks for answers

What is the average latency between your home connection and your job connection?

Approximately it can be about 3 seconds when it is very slow and more sometimes.

Bitch to your isp (not that they will do anything) they are probably optimizing for d/l and not for interactivity (3 seconds is just far too long). There are some things you can do to make your end a little more interactive but it is limited in effectiveness.

If you look at this you might get some ideas on how you could shape your traffic to make it more resposive on your end up I would not be terribly optimistic.

it shouldnt matter if you are on dsl or on cable, these optimizations are for adjusting priorities internally before they hit the modem. I would warn you though that they may not help at all (unless you are saturating your own connection)

Ok, thanks for the tip.
It's a weird way, but I thinks that's could work.

Try using the compression in ssh?

ssh -XC user@host

The X is for X11 forwarding.. great fun!

I use this when I am at home on my dialup, and it is much more responsive.
