-====== Frequently Asked Questions ====== 
-===== General ===== 
  
-===== Networking ===== 
-==== HowTo move my mail from PINE to IMAP ====

- 
-==== 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.

-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// 
-

-==== 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.
