nam-shub-01 upgraded to RHEL8

Nam-shub-01 has been upgraded to RHEL8. As this machine has a lot of special features, there may be things we and the automated systems have overlooked in the upgrade, so please let us know about any outstanding changes.

One thing worth nothing though is that the host key you encounter when you ssh to the machine has indeed changed. This is a security precaution, so when you now try to access nam-shub-01 from non-UiO machines, you may see something like the following:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
51:82:00:1c:7e:6f:ac:ac:de:f1:53:08:1c:7d:55:68.
Please contact your system administrator.
Add correct host key in /Users/terjekv/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/terjekv/.ssh/known_hosts:12
RSA host key for 129.240.75.227 has changed and you have requested strict checking.
Host key verification failed.

To resolve this issue, run:

ssh-keygen -R nam-shub-01

And

ssh-keygen -R 129.240.75.227

In the terminal that you are using to access nam-shub-01.
