Linux Servers

What are lxnsrv servers and who can use these machines?

The lnxsrv servers refers to a group of machines that may be used by non-EE classes. You need to be on the UCLA network to connect to these servers. If you are connecting from off-campus please login to the campus VPN server first.

  • If you login to lnxsrv.seas.ucla.edu, you will be logged into one of the machines that belong to lnxsrv servers.
  • You may use individual hostname if you want, but we recommend using lnxsrv.seas.ucla.edu because that will help with load balancing and system maintenance.
  • You need your SEAS account to access these machines, and you should be enrolled in one of the classes that are allowed to access lnxsrv servers.
  • You MUST be on the UCLA network in order to use the lnxsrv machines.
