-At [[mail:pine|this]] page you can find the solution.
-==== I need to Scan something ====

-If you want to write a bunch of files or an ISO image to a CD-ROM or to a Dvd-Rom you can use the workstation [[http://plan.epfl.ch/?room=INR015|lthcpc24.epfl.ch]]. To write a Cd-Rom or a Dvd-Rom just login in the workstation, insert your Cd-R or Dvd-R and select the image/directory you want burn on the optical drive. The burner is wuit fast, so the operation will tak at most 20 minutes.
-<note>
-You can use Cd-R, Cd-Rw, Dvd-R, Dvd-Rw, Dvd+R, Dvd+Rw

-===== Unix and Linux =====
-Your home directory is named: ///home/YourLoginName//
-\\
-====  Shells and Environment Customization ====
-By default, you have a bourne shell (bash), meaning you can also type: //cd ~SomeLoginName// (eg: ~deatrich ) to reach your homedir.
-The bash shell has many features, read the man page for more help.
-\\
-If you want to modify your environment, then you typically need to edit your //.bash_profile// and/or your //.bashrc// file. For instance, suppose you want to add an alias to ...:
- $ alias 'lstime=ls -latr'
-This line means that every time you insert in the command line the command //lstime//, the bash will execute the more complex command //ls -lart//
-(not yet complete)
-==== How to run several X-Servers simultaneously ====
-Have you ever wondered why Linux has 6 different virtual text-terminals but only one graphic-terminal? In fact, Linux has also 6 graphic terminals, it just uses only one by default.
-When you start your X-Server with the command "startx", the system assumes, you want to send the graphical output to the first graphic-terminal, which you can access by pressing Ctrl-Alt-F7.
-  "startx -- :0"
-is normally the same as just "startx", it puts the graphics to the first graphic-terminal
-  "startx -- :1"
-starts another X-Server with its output to the second graphic-terminal
-  "startx -- :2"
-starts another X-Server with its output to the third graphic-terminal
-... so we can run upto 6 different X-Servers simultaneously!
-You probably already knew, that you can switch between the text-terminals with the combination Alt- and the F1 to F6 keys.
-Parallel you can switch between the graphic-terminals with Ctrl-Alt- and F7 to F12.
-==== How to connect to a remote X-Server, i.e. control it ====
-Have you noticed that, when you open an X-Server on your box, the system will open the port 7000 (thats the standard)? So it seems possible to connect to this port and trasmit the graphic data over a network(i.e. the internet). For this to be possible you have to do the following configuration steps:
-  - On the server:
-     - Allowing the server to send data to your client :
-       "xhost +[ip]" whereas [ip] is the IP of the client
-  - On the client:
-     - Setting the server output to the remote X-Client:
-     "export DISPLAY="[ip]:0" whereas [ip] is the IP of the client
-After doing this all programs that use X which are executed on the server will be visible and controllable on the client. The CPU time used by the program, however, will be the server one's.
-Thats pretty much it. I hope that wasn't too cryptic. Have fun.
-===== Mac =====
-===== Windows =====
-=== Why can't I run Windows OS on my my workstation ? ===
-Because it sucks and it would require too much of our time to setup, fix, upgrade, keep away from viruses, etc.
