connect to remote server

[watergrinder]

Could anybody tell how to connect to a different server and execute commands? Let's say I have a
script on server A. I also need to gather same statistics on server b . Can I connect to the other
server? Can I also execute commands like SQLPLUS etc..?
Thanks in advance.

You may consider rlogin, telnet, and depending or your *nix flavor either remsh or rcmd or rsh.

A sophisticated way is executing the remote command via ssh, because it is encrypted and password-protected.
Previously you must of course install and configure openssh. If properly setup, no password needs to be typed in, because
public keys can be exchanged and copied into ~/.ssh/authorized_keys (if open-ssh is used). If you don't need this comfort, you don't even have to do that, but you'll be asked for the ssh-keyword when issuing the commands.

Assuming ssh is correct configured, a remote command could look like: " # ssh -l root 192.168.2.1 df -k " and you get the result on your terminal.
That's it.

telnet and the "r -commands (rsh etc) shouldn't be used for security-reasons, because everything is transmitted in clear text.

Hope this helps.
