Remote Login Service

Faq / May 10, 2020

The CAEN Linux Login Service allows authorized CAEN Account holders to access special editions of the CAEN Lab Software Environment (CLSE) for Linux over the network. This is the only way to access the CLSE for Linux from off-campus, and is intended to provide the same user interface as CAEN computer labs. The availability of some software may differ from CAEN labs due to vendor license terms, software compatibility, and performance limitations of the system. See the CAEN Software Listings Overview for more information about which software applications are available using this service.

The CAEN Linux Login Service provides different software libraries for individuals who connect from on-campus or off-campus networks.

  • provides access to software that is licensed for use from any network location.
  • provides access to software that is restricted to on-campus use. This service may only be accessed from on-campus networks (excluding U-M VPN networks).
  • provides access to software that requires two-factor authentication with a Duo two-factor option.

Students should obtain information about which software library to use from their instructors.

All services listed above may be accessed using the CAEN VNC client or Secure Shell (SSH).

Appropriate Use of the Linux Login Service

The CAEN Linux Login Service is intended for interactive use and should not be used for long-running CPU, memory, or I/O intensive jobs. Many CAEN Account holders rely on the Linux Login Service and CAEN’s policy is intended to help everyone use this shared resource in a fair and consistent manner, and to prevent a single or small number of individuals from monopolizing it.
