Note: Beginning Wednesday October 3, 2018, access to all CAEN remote access services, both Windows Remote Desktop and Linux Login/VNC, will require Duo Two-Factor Authentication at U-M (previously only off-campus access required it).
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.
- login-course.engin.umich.edu provides access to software that is licensed for use from any network location.
- oncampus-course.engin.umich.edu provides access to software that is restricted to on-campus networks (excluding U-M VPN networks).
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).
The CAEN VNC Client
Create a VNC connection and display the full CLSE for Linux login session on your computer’s display using CAEN’s VNC client.
Secure Shell (SSH)
Establish an SSH connection to a Linux login server for a terminal, command-line interface.
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.
To ensure the availability of this service for as many people as possible, CAEN monitors the Linux Login Service to detect when resource-intensive processes are being run. CAEN reserves the right to end any resource-intensive processes running on the service. Repeated violations of this policy may result in CAEN restricting a user’s access to the service.
The University’s high performance computing cluster, Flux, is available for course-related and research use.
