Hello all,

 

I'd like to get started using OpenSSH, which I've installed via UnMENU; however I'm having a hard time finding a good guide for beginners to get it up and running. Upon install it advised me to ensure several usernames had strong passwords (nobody, root, etc) how do I change these passwords? A bit confused at the moment and any help would be appreciated!

 

Thanks!

The root password is set in the web GUI. nobody has /bin/false as a shell and can't be used for a login so the password is not that important. Look in the /etc/passwd file for the other logins and make sure they have /bin/false as a shell. I'd bet they do.

unless you are running a very different version of unRAID than me, or a very current version, I'll bet they do not.

 

Try logging into your server as shutdown, or halt, or sync, or operator.

 

See what happens.

Only name to login is 'root' ...

Okay so I think I have the logins pretty well locked down; now I'm trying to login using keys in lieu of passwords. I generated a public/private key on my Android phone and copied it to my server, then run the following command

 

cat .ssh/[KeyNAME].pub | ssh [username]@[server] 'cat >> .ssh/authorized_keys'

 

this works until I reboot, how do I get this to persist?

 

I've also tried to change the default port my modifying sshdconfig in /boot/custom/etc/ssh, but no dice. Am I modifying the wrong file?

 

Thanks!

Put the key on the flash drive and then copy it into place in the go file.
