All information given is for computer accounts valid for workplaces of the department and maintained by Technical Service, 

Important Note

Because of limited space for user names account names and the linked email addresses can be reissued 9 months after the deletion of the old account. They are therefore not a suitable means of identifying users after the account expires (e.g. for administrative systems) or for authentification (e.g. web applications, mailing lists). Before deleting their account users therefore should cancel all authentifications via this account or the linked email address.


Four different sorts of accounts exist: 

Computer accounts for students of Computer Science degree programs

These students generally receive personal computer accounts at the start of their studies. Requirements are a StudiDB account and at least one registration for an exercise via the StudiDB. Technical Service uses the information in the StudiDB to create computer accounts. The teaching assistants hand out the account information at the start of the winter semester. Furthermore, information on personal computer accounts can be attained at Technical Service (CAP4, 12th floor), showing a valid student's card and ID.

Other personal computer accounts (employees, guests, master students, minor study, change of subject, students without account)

Personal computer accounts for user groups like advanced students without a computer account, who already have a StudiDB account and are registered for at least one current exercise via the StudiDB, new staff members and guests of workgroups who stay for a longer time, the creation of a computer account requires the following steps:

First, the applicant has to fill in a web form. The web form is accessible from each computer with campus network access (e.g. EDUROAM Wifi, VPN). To ensure the privacy of the data, they are transferred via an encrypted http-connection.

Second, the students need to show a valid student's card and ID to Technical Service.

Staff members' authentication is checked with the dean's office.

Guest's authentication is checked with the person responsible of the inviting workgroup.

Only then the computer account is being created by Technical Service.

Exercise accounts

For special courses, like preparatory courses or advanced education for teachers, creating personal computer accounts is too time-consuming; for exams personal computer accounts are not desirable. Staff members in such cases can apply for anonymous exercise accounts via email to account.  

Software and project accounts

You can apply for software or project accounts via email to account. We ask you to provide the following information: 

  • desired login name of the sofware or project account
  • detailed name (gcos) of the software or project account
  • initial quota of the software or project account
  • name and workgroup of the person responsible for this software or project account
  • login name and comuter for the first entry into the .rhosts-fie of the software or project account

​Only staff members of the Department of Computer Science who have a valid personal computer account on one of the computer administered by Technical Service may be responsible for software or project accounts.



All computer accounts are valid for a maximum of one year to simplify the deletion of unnecessary computer accounts. Computer account can be renewed for an additional year at the start of each winter semester. Before the date of re-registration, students and responsible Persons for guests will receive a mail, detailing the renewal process and which deadlines have to be met. Personal computer accounts of students in Bachelor's, Master's and Diploma degree programs of the Department of Computer Science are renewed automatically, if the students have reregistered within the deadlines. All other students personally need to visit Technical Service and present a valid student's card and ID card. Personal computer accounts of staff members are generally prolonged automatically as long as their contracts exists. This does not extend to the guest, software or project accounts. To renew these accounts, please answer the received email. 

Former students and staff members, who want to keep their account after the reregistration date, need to find a Computer Science staff member who will take responsibility for the personal computer account in the future.  


All users, who have a personal computer account on one of the workstations administered by Technical Service, only have a limited amount of memory (quota). To find out, how big your quota is, use the system command 'quota -v'. The resulting output often is a little puzzling to users at first. 

Look at this example: 

rechner{hugo} quota -v
Disk quotas for hugo (uid 450):
Filesystem     usage  quota  limit    timeleft  files  quota  limit    timeleft
/home/user_1       0      1      1                  0      1      1            
/home/hugo       974  30000  33000                150   3000   3300            


The only line interesting to you is the one that spots your own computer account name. In this case, the user 'hugo' has a temporarily exceedable quota of 30MB (quota) of which he only uses 974KB (usage). The limit that may not be exceeded on this computer account is 33MB (limit).

The quota of 'hugo' (here: 30MB) can be exceeded for a maximum of 7 days up to the limit (here: 33MB). After this point no opened file can be closed any more, even if the maximal limit has not yet been reached. Now you first need to delete enough files to let the used memory of the computer account (usage) be lower than the quota.

Note: Logging in directly via a console of a workstation computer will not work any more, if no file can be opened and closed any more in the user's user directory. The remote login to a workstation computer via s-protocols (ssh, slogin) will still be possible.

Raising quota

Before asking Technical Service for additional memory space, take care, that no memory space is wasted to unnecessary saved data. Several automatically generated files can be deleted without any plroblems. These are files that are generated when using TeX (e.g.  '*.aux', '*.log', '*.dvi', '*.ps', etc.) or backup files of editors (e.g. '*.BAK', '*~', etc.). When all unnecessary files have been deleted and memory is still insufficient, you can apply for a higher quota.

If you have a computer account on one of the workstations administered by Technical Service, then send an email to admin, including the following data:



user's first name and surname 

current quota

new quota


Especially the last point is of high importance, because memory space is not endless. Staff members are thus prioritizing the need for additional memory and this is only possible, when knowing the reasons for the application.
