FAQ

What changed with the update to Jessie?

Login

I just completed the registration form. How long does it take before I can actually use my login?

Normally until the next day, sometimes a bit longer.

How do I change my password?

Use the command cip-set-password.

How do I change my password for the windows systems?

Use the command cip-set-windows-password on a linux machine.

I have forgotten my password.

Please come by during consultation hours. A new password has to be set with the help of the administrator and this cannot be done via e-mail or phone. You have to appear in person and bring a student and photo id.

How can I change my login-shell?

You can change your login-shell with the program cip-chsh.

How much disk-quota (space) do I have as part of my CIP-login?

Every student has a fixed limit of disk space for his home. You can check how much of this you have in use with the command cip-quota.

If you need more space, there are several possibilities:

I can't logon. If I try a blue screen appears for a second and the logon prompt appears again.

It is very likely that you have too high diskusage. To delete some files it is possible to use the Console of a Linux box. You can access the console by typing Ctrl-Alt-F1. Logon with username and password and you get a shell. Now you can check your diskusage with cip-quota. If you're over diskquota you can delete some files using rm. When you are still over diskquota use ncdu to see your files in the current directory. Use the cursor keys to select the file or folder you want to delete, then press d. To exit ncdu press q. As soon as cip-quota tells you that your're no longer over diskquota you can logout from the console, switch back to the Xwindow system using Ctrl-Alt-F7 and continue your work.

Software

How can I obtain a list of the installed software?

See software.

Audio playback does not work

Make sure source and output device are turned on and set to a high volume in pavucontrol (Multimedia -> PulseAudio Volume Control). In case you can't see any source or output devices, delete ~/.pulse and restart pulseaudio (pkill pulseaudio). Please contact us if there is still no sound.

Eclipse refuses to start or open my workspace

Most likely Eclipse wasn't shut down properly the last time you used it. Back up your data and remove the lock file in your workspace (location of workspace may differ):

cp -rf ~/workspace ~/workspace.bak
rm ~/workspace/.metadata/lock

Mozilla Firefox (or Iceweasel) complains about being alredy started as $PID on $HOST

Unfortunately Firefox doesn't play nice with shared homes over NFS. You can terminate the old instance, so you can open a new one:

ssh login@$HOST
kill $PID

Or you can create a new Profile for each host you're running Firefox simultaneously:

firefox -ProfileManager

Warning: Manually deleting the lock files (.lock, .parentlock) in your Firefox-Profile will most likely break your profile!

Hardware

Is there a possibility to mount usb-sticks and hard drives in the CIP-pool?

After plugging in the stick, it can be mounted with the command cip-mountusb. Do not forget to umount it before disconnecting! This is done with cip-umountusb. Supported file systems are FAT and NTFS.

How can I mount CDs/DVDs in the CIP-pool?

Insert your disk into the drive, then type mount /dev/cdrom or mount /dev/dvd depending on the filesystem on your disk (typically you want /dev/cdrom). If in doubt, try both. The disk will be mounted to /media/cdrom or /media/dvd, respectively. When you're done using the disk, type umount /media/cdrom or umount /media/dvd, followed by eject to open the disk tray.

How can I burn a CD in the CIP-Pool?

The easiest way to burn a CD/DVD is to use the graphical program brasero, which should guide you through the whole process.

Alternatively you can use genisoimage and wodim.

A computer is shut-down, what can I do?

Some machines power-down automatically during evenings and week-ends to save power. You can always start those machines by pressing the power button. As long as you're logged in they won't power down again.
