Log into the cluster on a new console, change into the.Next, you open the id_rsa.pub file with a text editor again.This would be more secure, but also means that you have to enter the passphrase at regular intervals. You will be asked whether you want to specify a passphrase.In that case you can either cancel key generation by pressing Ctrl+C and use the existing key pair, or specify another name or path for the new key pair.

The line User is for the username with which you want to login every time. The first line is the name of your shortcut. ![]() To do that, open the file /.ssh/config on your computer (not the cluster!) with a text editor and enter: host omni ![]() You can preconfigure your SSH connection to the cluster so that you do not need to enter the lengthy SSH command above every time. This is only recommended if an application does not work with -X. The difference is that with -Y the connection is treated as “trusted”, meaning fewer security checks are performed. ssh X forwardingįor a connection with X forwarding, i.e. connections that allow opening windows, the SSH connection needs to be started with the -X option: ssh -X the -Y option does mostly the same. In the Linux console you can open an SSH connection with the ssh command.
