Hi Richard

apt-get install ssh

Then it should just work (I think Ubuntu includes ssh-server as well as the client). You would "ssh ip_of_server" from another linux box, or run something like putty "putty ip_of_server" from a windows machine.

The configuration would be stored in /etc/ssh/sshd_config (at least on debian, and I believe ubuntu is similar)

Out of the box it should be reasonably secure (ubuntu not having a root account especially)

Hi

I have jumped to 16.10. And surprisingly you answered my next question! How do I install and use ssh on a nix box please? I have installed and also set up a static IP address. Now just need to know how to connect to it!

Thanks for the help and sorry for taking the fun away. I have been given another laptop. I might go through the same process and after breaking it - come and learn how to rebuild then!

Glad to hear it, although you did kind of miss out on all of the "fun"
of fixing what would have ultimately been a relatively minor problem.

For your own sanity I hugely recommend installing SSH and assigning (I'm
presuming this is your main PC) it a static IP address so you if
something like this happens again you can always remote into it without
having to check the DHCP leases on your router to find out where it is
on the network. Outside of specialist corporate scenarios I struggle to
think of a reason why one wouldn't want SSH on their *nix machines, it's
completely invaluable!

sudo apt install openssh-* -y

There are many different ways to assign a static IP (via NetworkManager,
WICD, /etc/network/interfaces) but a quick google will let you choose
whichever suits you.

Did you stick with 16.04 for LTS or jump to 16.10?

Cheers

FYI

ssh username@xxxxxxxxxxxxx -X

will allow you to run X11 things remotely (you need a good connection) like say synaptic and the GUI will appear on your machine (if running a desktop) - this can be really handy.

SSH X forwarding can be abysmally slow .. I'd recommend VNC over X forwarding any day. x11vnc is the package to show the existing desktop, whereas vnc-server will create a remote X server, rather than the actual X desktop on the target machine :) You can use ssvnc if you need to wrap it through SSH (ie creates a tunnel for encrypted connections) but I have found this a bit tricky with x11vnc on occasions - YMMV and all that. You can of course ssh and tunnel the VNC port manually if you're over an insecure (Eg. internet) link and not your own personal LAN. Enjoy!

X forwarding tends to work ok on you house wifi setup - and more importantly works seems to work without messing about trying to set up a desktop on a headless server!
