Maybe, instead of re-coding the telnet protocol, maybe it is easier to execute ssh (ssh is the encrypted version of telnet)
the good thing about ssh is that it can authenticate with PKI keys. so you don't have to specify a password. Placing the keys in the right directories is all you need to do. It's also a lot safer then telnet (everything, including the passwd is encrypted, bad news for sniffers...) then you just fire the command : ssh username@servername command_to_execute. This you can call easily from java using the System and Runtime classes, so you can even retrieve the return-code from it. more info: www.openssh.org Mike On Wed, 2002-09-04 at 07:57, Pramod Nair wrote: > The TELNET RFC should help you.
