how to let the remote server continuously run while I shut down local telnet client

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

I hereby accuse Joe Beanfish of stating:

This is exactly what you want. Install screen, then when you want to start a resumeable session, type "screen" first to enter screen's virtual terminal. Then use is as if you were using your normal command line.

You can "detach" the screen session at any time by pressing ^A (the screen escape key) and then D (for Detach). Screen and any processes started within it continue running in the background. You can log out and they will keep going.

When you want to reattach the screen session later, simply execute "screen -r". Much like the fg-bg commands, you can have multiple sessions going at once, so -r takes a numeric argument indicating the session number.

Since a screen session can only be attached in one place at a time, screen also allows you to forcibly detach a session of yours that is running on some other terminal by using "screen -d". This is useful for resuming your session if your connection drops before you have a chance to gracefully detach your session.

Two things screen cannot do: - sessions cannot persist across reboots (it's not a virtual machine or anything!) - cannot detach-reattach X windows

So if you're doing this in a GUI, screen is not going to work for you, but if this is a CLI process, it's exactly what you want.

Note that screen also does nifty things like splitting terminals into Emacs-esque "windows" and such. Read its man page.
