On Linux Using ssh-keygen On a linux operating system, generate your public/private key pair using the ssh-keygen command, as follows: $ ssh-keygen -t rsa -b 2048 -C "me@somewhere.ac.uk" -f ~/.ssh/id_rsa_jasmin The above command will ask you to enter a passphrase to protect your SSH key. It is a requirement for access to JASMIN machines that you use a passphrase. The output should look something like: Generating public/private rsa key pair. Enter passphrase (empty for no passphrase): <ADD PASSPHRASE HERE> Enter same passphrase again: <REPEAT PASSPHRASE HERE> Your identification has been saved in /home/users/meuser/.ssh/id_rsa_jasmin. Your public key has been saved in /home/users/meuser/.ssh/id_rsa_jasmin.pub. The key fingerprint is: 74:14:95:8a:31:73:cc:5c:af:be:91:04:01:c2:39:0b me@somewhere.ac.uk Running this command will generate two files in your $HOME/.ssh/ directory: id_rsa_jasmin - the private key (which should have permission "400", i.e. readable only by you) id_rsa_jasmin.pub - the public key It is now possible to move your public key file (id_rsa_jasmin.pub) to another machine so that you can use it to login. In some computing environments this is done by appending the public key file to the authorized_keys file in the $HOME/.ssh directory on the server you wish to login to. Please do not attempt to do this for JASMIN servers, however, as this process is managed automatically and any manual entries will be over-written. In order to login to JASMIN servers you need to provide CEDA with a copy of your public key file (id_rsa_jasmin.pub). Please see instructions for registering your SSH key here.
