Always use the short hostname for ssh/rsync, either the generic names blogin, glogin or the specific names like blogin5, glogin2, etc. This allows the usage of the direct intersite connection HLRN Link, which ich much faster then the internet connection, which is used, when you access the nodes of the other site by the hostnames b/glogin.hlrn.de.

  • configuration files
  • source code and executables
• limited disk space
