When I log into a Linux computer, I either cannot run software (e.g. command not found), the top bar/desktop is missing, or am automatically logged out. Why?
There are a few issues that can cause this behavior:
- When you are over your AFS storage quota, Linux cannot write necessary session information to your home directory. Visit this page for tips on reducing your AFS quota usage.
- If there is a problem with your Linux dotfiles (i.e. account configuration files), your session may not be able to start properly. You can reset them by logging into a CAEN login server using SSH, and typing the following command:
/usr/caen/bin/redotThis will rename your old dotfiles to .dotfile.old or .dotfile.older, and copy the standard dotfiles into your home directory. The next time you log into a Linux computer, your environment will use the CAEN default settings; as if you were logging into a CAEN Linux computer for the first time.
- Many software applications are restricted based on an individuals role at the College and/or where they are located when attempting to run software. Refer to our online Software Restrictions for Linux Users page for more information.
