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
If you need more space, there are several possibilities:
/proj/ciptmp: temporary storage provided by us with some restrictions, see
sshfs: if you have storage on an SSH-accessible machine, you can import it. See
man sshfsfor details and note the mountpoint must be accessible by
root, i.e. can not be in your home or another NFS mount.
- bring an external harddisk or USB drive
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
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
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
Ctrl-Alt-F7 and continue your work.
How can I obtain a list of the installed software?
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 (
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
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:
Warning: Manually deleting the lock files (.lock, .parentlock) in your Firefox-Profile will most likely break your profile!
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
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
/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/dvd, respectively. When you're done using the disk, type
umount /media/dvd, followed by
eject to open the disk
How can I burn a CD in the CIP-Pool?
The easiest way to burn a CD/DVD is to use the graphical program
