Network security outline

• Outside world
• The internet, SLAC-VISITOR wi-fi network, etc.
• SLAC network
• VPN
• SSH bastion hosts
• Proxy
• FastX
• Citrix
• SLAC computers
• https://sites.slac.stanford.edu/remote-tool-kit/connecting-slac-networks-remotely
• Controls network
• mcclogin -> facet-srv01
• Controls computers

FastX (demo)

• https://fastx3.slac.stanford.edu:3300
• https://confluence.slac.stanford.edu/display/SCSPub/FastX
• Don’t store anything on a FastX machine that you can’t lose!
• NoMachine
• https://confluence.slac.stanford.edu/display/SCSPub/NoMachine
• Browser-based available; desktop client preferred

Unix / Linux command line basics (demo)

• ssh – connecting to remote systems
• cd, ls, mkdir, cp, mv, rm – basic navigation of file system
• cat, nano, vim – read and edit files
• scp, rsync – moving files between remote systems

Windows users may find PuTTY (SSH client) or Cygwin (~Unix emulator) useful. Virtual machines are also easy to set up

FACET specific computing

• https://confluence.slac.stanford.edu/display/FACET/Remote+access+to+facethome+and+facet-srv01
• Follow steps to have your account granted access to facet-srv01
• facethome is a hub for FACET controls
• Get to controls network (e.g. FastX, ssh mcclogin, ssh fphysics@facet-srv01)
• Launch facethome
• Experiment data (https://confluence.slac.stanford.edu/display/FACET/Data+Retrieval)
• Initially saved to FACET NAS (controls network only)
• Uploaded daily to SLAC central /nfs/slac/g/facetdata/nas/
• Your home directory is synced between, e.g. centos7 and mcclogin, but not facet-srv01�
