如何在打开新终端时自动登录ssh服务

Question

I have a vncsession running on server. Now, whenever I open a new terminal, I have to ssh to another server. Till now I have been able to setup ssh such that it doesn't ask for password for this particular server. But I have not been able to automatically do this in new terminal. If I add the ssh command to .tcshrc it goes into recursive loop - ssh into server, execute .tcshrc, ssh to server, so on.

I'm using Linux, cshell, Gnome setup.

Answer 1

You should do a hostname check. Or something else you could recognize the difference between the client and the target. I don't know cshell scripting but in SH you would want to do something like:

# Shell:
if [ $HOSTNAME == "vncserver" ]; then
    ssh $TARGET_BOX;
fi;

# Cshell:
if ( $HOSTNAME == vncserver )
    ssh $TARGET_BOX;
endif

This would enforce that only the svnserver would ssh to the remote system and the remote system won't ssh to itself.

I use ssh-agent and keychain that works like a charm and allows keeping some safety on your servers. Here is another keychain tutorial (sorry, written only in french). Just putting your keychain commands in your bashrc or profile that runs at tty start.
