Get inside the university networks¶

One cannot connect to all UPPMAX clusters everywhere around the world. Instead, one needs to get inside the university networks first. This page described how to get inside the university networks, or, to use more precise language, to obtain a SUNET Internet Protocol ('IP') address.

There are these ways to do this:

Physically move inside SUNET
Use a VPN (a 'virtual private network')
Use an HPC cluster within SUNET

Each of these three ways are described below.

Physically move inside SUNET¶

To connect to all UPPMAX clusters, one must be inside SUNET.

All Swedish university buildings are within SUNET. Hence, working from a University building is a non-technical solution to get direct access to Bianca.

Use a virtual private network¶

Install VPN client for Ubuntu and Uppsala university

To connect to all UPPMAX clusters, one must be inside SUNET.

A virtual private network (VPN) allows one to access all UPPMAX clusters indirectly: your computer connects to the VPN within SUNET, where that VPN accesses your favorite UPPMAX cluster.

To be able to use a VPN to get inside of SUNET:

For Uppsala University: go to this page
For Lund University: go to this page
For other Swedish universities, search their websites to get the required VPN credentials.

Use an HPC cluster within SUNET¶

To connect to all UPPMAX clusters, one must be inside SUNET.

An HPC cluster within SUNET (for example, Rackham) allows one to access all other clusters: your computer connects to the HPC cluster within SUNET, after which one accesses all other clusters.

However, when using this method, one can only use the console environments (i.e. no remote desktop environment).
