Linux Environment Settings


All users have storage quotas on /afs filesystem. If you encounter problems, verify first if you exceeded your quota:

fs lq ~

Namely, home folders are being backed up, therefore having large amounts of data there is not desirable.

Large amounts of data can be stored on /afs/<project> (eg. /afs/

Project folders will be created upon request.

Locations for applications installs and project configurations that do need backing up, should be at /afs/<projekt> (eg. /afs/

If you need a private scratch space, you can use /afs/<username> (eg. /afs/

This location is also created upon request.

Zaščita v AFS


All subfolders in your home folder are readable by users. If you want to protect a certain folder, use the following:

fs setacl system:authuser none

while located in eg. /afs/

Apart from this, we also recommend updating your passwords from trivial (weather phenomena, music groups, etc.) into something more complex.

AFS tokens

Access to AFS from your login sessions lasts only 25 hours, after that, your token expires. If that happens, eg. overnight, use the following:



First command will ask you for password, while the second one will renew your token.

Screensavers renew AFS tokens automatically.


If you delete a file or folder by mistake, or if you modify it beyond recognition, the old version is accessible at

  • /afs/<username> (eg. /afs/

This folder is a copy of your home folder from previous day and gets updated with current version overnight. Backup to another location is also generated weekly, the oldest copy being 5 weeks old.
