Have you found 'tools' to assist removing delay from the typical connection, especially as it relates to ssh?
actually, i think the problem you are seeing is moreso related to the asymetric nature of the connection (i think you were referring to directway which is a "one-way" satelite feed). i generally only use such connections for front-ending a squid server. the problem is that the round trip routing of your packets gets pretty diverse. when you type the packets go out the modem, across a terrestrial network to the uplink, then back down over satelite. not much can be done to make that better. if you "own" the network, there are some tunneling things you can do to make things appear to be less asymetric, which might help, but if you are an end-user, you'll just have to tough it out. alternately, configure your router/etc to use the IP of your dial-up connection for ssh/telnet, instead of the IP of the downlink. this will make your telnet/ssh work using only the dial-up connection, which will eliminate the asymetric routing. (ie. interactive traffic uses the dial-up addr, "bulk" services use the downlink). -- [ Jim Mercer jim@reptiles.org +1 416 410-5633 ] [ I want to live forever, or die trying. ]
Actually, it's a two-way connection, and I sent you a private e-mail, but hey, in front of 10k folks is cool.... :>

hmmm, ok, my bad. if it is two-way, then the telnet/ssh buffering shouldn't be that bad. at least in my opinion. i use ssh over (two-way) satelite connections all the time, and usually don't have much trouble unless the link is full.

i figured my response might be informative to others in a similar (albeit mis-interpreted) situation.
