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 separated from the main GSI computer networks and can be accessed only through a limited number of proxy hosts. User profiles inside the yrlx pool are roamed and you should find a equivalent work environment on any of these computers.

Please be advised:
  • The pool is still largely in development. Apologies in advance, should you observe any hiccups!
  • We do not create backups of your data. This is entirely your own responsiblity!
  • Should you be missing essential software, please let us know.
  • Disk access is limited by a (failry adequate) quota.
We do our best to track the stable release of Debian and to keep all systems in sync.

SSH Fingerprints

The SSH host keys for all computers belonging to the yrlx pool have been signed. If you add the following CA public certificate to your ~/.ssh/known_hosts file, the host keys will be verified without asking you for fingerprint checking. Please make sure you save this one-line-entry.
@cert-authority *.cryring.lan,atppc025.gsi.de ssh-rsa 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 michael@atppc025

The added benefit of the above certificate is, it reduces the clutter in your .ssh/known-hosts file.
