Read: SSH

FastX

• https://fastx3.slac.stanford.edu:3300/ (webbrowser)
• If the resolution is not high enough, e.g., to open camera monitors: turn off smart scaling and increase the resolution

  Image Modified

• Using fastx3 webinterface behind a firewall:
  • connect via ssh first via local port forwarding: ssh smeuren@fastx3.slac.stanford.edu -L 33000:localhost:3300
  • connect to localhost:33000 in your local browser (port 33000 is arbitrary, it just has to be consistent)

NoMachine

• Read here: NoMachine

Connecting to the SLAC network via ssh

• ssh smeuren@fastx3.slac.stanford.edu -Y
• ssh smeuren@centos7.slac.stanford.edu -Y
• ssh smeuren@rhel6-64.slac.stanford.edu -Y

...

Login via ssh without password

1. 1. Generate a key on

...

1. 1. your local computer (default options, empty passphrase):

...

1. 1. "ssh-keygen -t rsa

...

1. 1. "

   2. Find the folder where the "authorized_keys" folder is located on the remote server:

   3. Let the server know that you are authorized to login without password:
      
      • cat /home/seb/

...

1. 1. • .ssh/id_rsa.pub | ssh

...

1. 1. • smeuren@fastx3.slac.stanford.edu 'cat >> /home/smeuren/.ssh/authorized_keys'
      • Note that you need to change username / servername and the location of "authorized_keys" (pwd when you log into the server should help; see step b)
      • login without password

ssh with port tunnel

• • creating a port tunnel to the FACET control server: ssh fphysics@facet-srv01 -Y -R 42000:e320pi:42000

    (note difference between local and remote port forwarding, i.e., direction: server on remote or server on local -L / -R)

Get access to the control server

• get an fphysics account: Remote access to facethome and facet-srv01

• after you have access: follow instructions given directly after login to create your personal profile

Troubleshooting

• Read: SSH
• In case your login fails: test "klist". If there is nothing, do kinit
  
  
  
  
• If you don't have write access to your AFS filesystem or you have some issues with ssh-keys that cannot be read: aklog. After this, klist should read similar to this:

Various Tricks

Screen capture on control computer

...

from cluster to control server:
smeuren@mcclogin $ scp -r /afs/slac.stanford.edu/u/gu/smeuren/ "filename" fphysics@facet-srv01:/home/fphysics/smeuren/

Facet-II elog

http://physics-elog.slac.stanford.edu/facetelog/index.jsp

...

• ssh to mcclogin (-Y), ssh to, e.g., fastx3
• run firefox there
