KI 2346 Immediate shutdown of SSH access to linux client machines

Unfortunately, we have to make an immediate change which means that all ssh accesses on linux-client machines will be shut down with immediate effect.

We will of course open up the possibility for those who own the machine to be able to use ssh for their own machine.

Make an issue in hjelb.uib.no, using this link, then we will prioritize these users; https://hjelp.uib.no/tas/public/ssp/content/serviceflow?unid=6340ffecbfb84640b1a3dcd0cbb73285&openedFromService=true

We apologize for the inconvenience this may cause.
