When you want to use these computers from the outside connect
with ssh to the server numerus.lingfil.uu.se
.
That computer also has shorter aliases you can use, primarily
cl.lingfil.uu.se
.
(If you work here and have one of these computers in your room you can preferably connect to that one instead. Also if you are sitting in one of the computer rooms with a laptop you can connect to the one you have right in front of you. But most of the time avoid connecting to those computers. If someone sits down at that computer they are supposed to have it for themselves.)
ssh
If you have a Unix compatible system like GNU/Linux you will have ssh on it. You can run it as
ssh -Y username@cl.lingfil.uu.se
For graphical programs that create windows to work you need to have
an X.Org X Window System
(or equivalent) running on your computer.
With GNU/Linux you will have that. With macOS take a look at
XQuartz
for that.
The Windows 10 April 2018 update included a preinstalled OpenSSH client.
If you upgraded from an earlier version of Windows 10 you may need to manually enable it. See instructions about that here.
(Before that the most commonly used option for those using Microsoft Windows was to use Putty.)
That gives you a terminal window. To run programs that show
windows the most common server to use is Xming X Server for
Windows.
When I used Xming on a Microsoft Windows laptop in January 2022 I got an error
Then I had to do
(With the ssh client that comes with Putty instead I didn’t need to
do the last thing.) Maybe this will help someone else? /PerUsing Xming
ssh_askpass: posix_spawn: No such file or directory
.
To avoid I had to do mkdir \dev
and
echo x >\dev\tty
(once).
(I got help from here.)set DISPLAY=localhost:0
before doing
ssh -Y
, or otherwise DISPLAY
wouldn't be
set on the other end as well. This way DISPLAY
got a
working value so that graphical programs could be run on the
CLUU computer, showing windows on the laptop.
