Access From Off-Campus

For security reasons direct access to our systems is via SSH (Secure Shell) and is restricted to machines on the University of Leeds network. Note that the machines do not support access by the NoMachine protocol and only provide command-line access.

During the current remote-working time we ask that you AVOID using the VPN to access the HPC systems.  It can become overloaded very quickly and we ask that you avoid using the VPN wherever possible.

We ask that you access ARC through the supported remote-access Linux service. This is a minimal command-line Linux service that can be used as an intermediate (sometimes called a bastion) host to access University services.  In its very most basic sense, you can login to the service and then login again to the service you need. For example (replace username with your IT username):

ssh username@remote-access.leeds.ac.uk

and then when logged in:

ssh username@arc4.leeds.ac.uk

Don’t forget that you’ll need to logout TWICE (one for the HPC service and then again for remote-access).

For more detail on how to configure your ssh:

Take a look at this knowledge based article that gives you more information about how to configure ssh to use this remote-access service via a step-by-step guide.
