WinSCP from external
When connection to the HPC from an external connection you have to go via central.aber.ac.uk, even when using the VPN, however if you want to connect with a graphical file manager this becomes more complex.
To do this we need to 'tunnel' through central to get to bert. This can be done using WinSCP.
You will need to create a new site in WinSCP as per normal, configure this to bert like normal
Hostname: bert.ibers.aber.ac.uk Username: Your uni login Password: Your uni password Port Num: 22
Then in the advanced settings (got at by click the Advanced button), click on the Tunnel option in the side menu.
Tick connect through SSH tunnel, and then fill in the form with the follow details
Hostname: central.aber.ac.uk Username: Your uni login Password: Your uni password Port Num: 22
You should then be able to access your data on bert.
