As a storage admin i have come to a point where i want to run certain scripts from a Linux machine over on an MDS switch, and to do that i had to get a passwordless login into the MDS switch.
To do that i just added my Linux root`s id_dsa.pub key (the user running my scripts) to the MDS admin user`s configuration like this:
On the linux machine: cat /root/.ssh/id_dsa.pub, copy the output.
On the mds switch: username admin sshkey <output from previous command>
Now user admin can login from the root`s user on my linux box without password and since user admin had a password, from other machines the login is using the password.
