How to get X up and working
Hints for Windows users:
For doing the exercises on our server you must be able to connect to
the server using Secure Shell (SSH) or Putty and tunnel X through the
How to do it? Begin by installing an X-server.
- You need an X-server running to see the unix GUI (grafical interface).
- Any X-server running on your computer will do. If you don't have one, then Xming can be downloaded here.
- And you also need to dowload this.
- You need Xming and Xming-fonts.
- Do a standard install - yes to all.
- When installing Xming Fonts, you will be told that
there already is a Xming folder, and if you want to install on top of
that. The correct answer is YES.
- When you are running this program, a small X will appear in your systray.
X-server must be running if you want to use X (clustalW, nedit, ghostview etc.) on the CBS server.
If it is the first time you are using this, you should make sure that
the configurations on the program that you are connecting to CBS
servers (such as SSH or putty) are suitable to open the X windows.
If you are connecting with SSH:
Edit -> Settings-> Tunneling-> X11 tunneling
Here just enable the X11 tunneling by clicking on the box at the end.
You get an image like this:
Then you say OK and close the application. It asks do you want to save the new settings : YES.
Now if the Xming ( or your X server) is running, open SSH and connect to CBS servers. Try:
nedit file &
on your command line and see if a window pops open to edit that file. (nedit is a text editor tool).
If it does, then you're ready to go!
If you are connecting with Putty:
When you run Putty, the configuration window opens first.
Go to Connection-> SSH -> X11 ( Options controlling SSH X11 forwarding)
Then Enable X11 forwarding.
Connect to CBS and try:
nedit file &
If it does, then it means you're set, and you can go on with your exercises.
