Sorry for the amazing delay in response, work is a little busy tonight for some odd reason...
Ok, so where were we, ah yes, SSH
SSH is done across a network not on the same system you are trying to connect to, well not normally. I am not sure if ssh'ing to the box you are on is a working function, mainly because you are already secure because there is NO network between you and the box.
When you SSH from a shell to a shell (from one linux box to another) you should try to use the following syntax/format:
ssh -l username box-ip
SO for a box with an ip of 18.104.22.168 that needs to be connected to:
ssh -l username 22.214.171.124
Where username is the username you want to login as.
If you are going to be ssh'ing from a windoze drive, open up a browser pointed at www.google.com
and type it "putty" and click "I'm feeling lucky" Hopefully you'll be on the Putty page which is a windoze SSH client. The only file you need is the single putty.exe file (I prefer the development version it's better).
Then, open up the file, and enter the hostname of the computer you are trying to connect to. Again, if there is not hostname you can do this via IP, but you will need to know the IP of the machine you are trying to connect to (you can get that from the machine by typing:
And it will show you the IP in one of the lines there. You will usually need to be root when typing that, and possibly with full path:
After you get the IP, go to the machine you'll be using SSH from (not the server, but the client) and try again, using the IP you just got.
If SSH is not running on the server (the machine you want to ssh into) then you'll need to either install it, or simply start it. You should consult some documentation from your distro on doing that since there are too many variables to address them all.
