Telnet functions.

By forbes ·
My telnet sessions sometimes seem to move very slowly. I realize the echo command will echo every character it receives. I was wondering if anybody knows of any tweaks of the telnet protocol that would speed things up a bit. I do utilize bandwidth reservation in my routers which seems to help things. I work in a system where telnet sessions are used frequently.

There's really nothing you can do, what you're describing is plain ole system usage lag. I would suspect that if you logged in via a dumb terminal right next to the machine, you'd experience the same thing.

Not much you can do about it, telnet uses TCP protocol which has a lot of overhead. You must have some slow links. Try ping and see how long it takes to get a response, less than 100ms is good but if it gets over 250ms telnet is going to be very slow. Hope this helps

whether or no this will help depends on a lot of factors, but SSH (http://www.ssh.com/) may be worth a try. Secureshell not only encrypts your data (telnet does send everything - including passwords - as plain text), but also provides an option (-C,i think) to use compression. of course, if it's the computer (either yours or the remote machine) and not the network, this may make things even worse. also bear in mind that ssh requires the installation of a daemon on the remote box, which is not always possible (or desirable).
