Accessibility

Most of AMS nodes are accessible (via ssh normally) only from the cern.ch domain. If you're outside this domain you have to log into an externally accessible machine first.

AMS Gateway

• ams.cern.ch aka pcamsf2.cern.ch: SLC5.4, Kernel 2.6.18 SMP64, 4xXeon DualCore CPU 3GHz, 12GB RAM, 4TB Disk space : Web Server, General User Support, lsf Server, AFS server.

  Servers

• pcamss0.cern.ch: SLC5.4 , Kernel 2.6.18, SMP64 2xXeon QuadCore CPU 2.66GHz 12GB RAM, 7TB Disk space, Production server, Fileserver, Primary DataBase server.
• pcamsf4.cern.ch: SLC5.4 , Kernel 2.6.18 SMP64, 2xXeon QuadCore CPU 2.33GHz, 8GB RAM, 4TB Disk space, LTO4 Unit : File server, AFS server, DataBase Backup.
