Figuring out network connection and cluster access
In this issue we discuss how to get the cluster online, and how to access the cluster
-
The plan is to do things in steps
- First we only need rudimentary access, at that level we only need to be able to connect our laptops to the router and ssh from there
-
At some point it could be ideal to put the cluster behind login.uib and then we'd need to configure ssh differently
-
But there are "unknown unknowns" so it is not known which final solution is viable and most optimal
-
We could end up with more or less the current setup as the final setup, a bit more polished of course, but we can't know for sure yet
-
For instance when a user wants to start from scratch, s/he needs to format the sd cards and possibly connect to the router/switch with a cable, it all depends on what we can achieve
-
PXE booting is possible for instance, it would be cool to try it out, but it requires some fiddling to make it work, and fiddling is fragile
