Interactive Linux servers

Login to GSI

• We provide a number of interactive Linux computers that can be used to login using SSH (read SSH Usage for more details).
  • If you use lx-pool.gsi.de or one of the other pools listed below for login, it will direct you to a pool of machines and distribute users homogeneously among them (load-balancing).
• In addition, the Linux desktop computers are provided for interactive use, too - either directly or also via SSH.

Purpose

• Users can access their home-directories on all interactive machines, as well as central file systems like /d/ (data storage) or /s/ (global scratch space).
  • These are the NFS based file systems.
• External access for all users from outside the GSI network is provided by a dedicated pool of interactive machines (lx-pool).
• Access to the HPC computing cluster (BatchFarm) and the Lustre file-system is provided by pools that are not directly available from outside GSI.
