Remote Access to MSI Systems
There are a variety of methods available to connect to MSI systems: SSH, NX, VNC and Citrix Receiver. The first two apply to our generally available Lab Queue nodes as well as our HPC systems. The third is limited to GPUT nodes, and the last applies only to Windows systems. Please note that we no longer allow direct access to machines in the SDVL, CGL, BSCL or BMSDL.
On a Mac or Linux system, accessing our lab queue is as simple as (in a terminal):
ssh -X <username>@login.msi.umn.edu isub
Alternatively, replace isub with an SSH directly to one of our HPC systems. For example:
ssh -X <username>@login.msi.umn.edu ssh -X itasca
In both examples <username> is your MSI username and the -X option starts a graphical X-forwarding session. You cannot run software directly on login.msi.umn.edu. An isub or SSH connection to an HPC resource is required. Refer to the isub documentation for additional options.
On Windows, PuTTY can be used for simple terminal commands. For graphical sessions on Windows we recommend NX. Note that running graphical programs with PuTTY is possible, but it requires additional software and configuration.
Background (non-interactive) batch jobs on lab machines are discouraged and should be submitted to the Lab PBS Queues.
For fast, modern graphical connections to MSI resources, we recommend an NX client. The NX workflow is similar to a direct SSH connection, since users must utilize the 'isub' and/or 'ssh' commands above to access MSI lab and HPC resources from the NX node (nx.msi.umn.edu). Software cannot be run directly on the NX node. Refer to the NX Client Configuration guide to start an NX session.
Virtual Network Computing (VNC)
VNC provides users with control of a complete virtual desktop on a remote machine including interactive keyboard and mouse events. MSI utilizes VNC for remote visualization and computing on the GPUT nodes. VNC depends on SSH and isub to initialize sessions. Refer to the GPUT session instructions to get started with TurboVNC and run hardware accelerated graphical applications with VirtualGL.
Files can be transferred to user home directories and/or group project directories on login.msi.umn.edu via scp, sftp, and rsync. When connected with a Remote Desktop client, users may also share local drives with the server. Refer to the File Transfer FAQ for more information, including suggestions for file transfer clients on your operating system.
