SSRL Beamline Computer Frequently Asked Questions


Question 1: How long can my data remain at SSRL?
Your data may remain for 30 days after your departure, but users are responsible for their data and are encouraged to transfer their data and make hard copy before their departure.

Question 2: How can I connect my laptop/pc to SSRL's network?
You no longer need to get an IP address from our Network Specialist. There is a DHCP connection at every beamline. The cable is a red cable with a tag which says type of connection: DHCP.

Question 3: How come I am unable to print from my laptop that is connected via DHCP to any SSRL's printers?
When any laptop or pc is connected via DHCP, the connection is outside SLAC's firewall, therefore you may access only the printers that are on visitor's subnet. For more information on how to access printers on visitors subnet, see the following web page: www-ssrl.slac.stanford.edu/computing/BLCOMP/printers.html.

Question 4: How come I am unable to see SSRL servers on my (mac/apple talk) that is connected via DHCP?
Again, when your mac is connected via DHCP, the connection is outside SLAC's firewall, therefore it is unable to see SSRL's servers.

Question 5: What is the command in VMS to print a file?
The command is: print/queue=queuename filename

Question 6: What is the command in VMS to copy files from one beamline to another?
The command is:
copy/lo s043"b_username password"::$user1:[b_username]*.*;* $user1:[b_username]
The above command copies all the files from s043 under $user1:[b_username] to $user1:[b_username] directory of current system user is logged into.

Question 7: What is the command in VMS to see the contents of a directory?
The command is: dir directoryname, (ex: dir $data:[b_username] this will show all the files that reside in $data:[b_username] directory)
