yrlx.cryring.lan

yrlx.cryring.lan is a pool of interactive Debian-based computers inside the Network at the CRYRING cave and its electronics containers. The network is private and largely isolated from the main GSI campus network. It can be accessed remotely through specific proxy hosts. User profiles inside the yrlx pool are roamed and you should find a uniform work environment on any of these computers.

Please be advised:

• Disk access is limited by a (fairly adequate and negotiable) quota.
• We do not create archives or backups of your data. It is entirely up to you to take care of your valuable data. If you or the system loses data, they are gone.
• If your account expires, we will delete your data in time and without further communication.
• Please avoid storing personal data on your account (i.e. passwords, chat protocols, email accounts, calendar data...)

We do our best to track the stable release of Debian with security updates and to keep all systems in sync.
