simplify ssh config #11

Closed schloett closed 1 year ago

schloett commented 1 year ago

It seems that on some systems/version, the options for Host g1-*.ikim.uk-essen.de c*.ikim.uk-essen.de slurmq.ikim.uk-essen.de aren't applied after resolving the hostname via Host g1-? c? c?? slurmq. Hence I moved the inside Host g1-? c? c?? slurmq and removed the rest => shorter config and advanced users will adapt it to their needs anyway.

The downside is that you can't use the fully-qualified name anymore. I'm not against that, but we'll need to adapt other parts of the documentation, e.g. instead of

ssh -v $USERNAME@login.ikim.uk-essen.de

it's just

ssh -v $USERNAME@ikim

Could you do a text search for .ikim.uk-essen.de across the docs?

schloett commented 1 year ago

Ah right, hadn't thought of that. Not being able to use the fully qualified name anymore would probably cause only more confusion... What about keeping both Host directives and duplicate the options? Could that cause another issue that I'm missing?

enasca commented 1 year ago

I don't mind if we delete the section with the fully qualified name. Since this is just a recommended setup to get started, there's merit in keeping it simple, so I would avoid duplication. I don't see any significant disadvantages in keeping short names only.

schloett commented 1 year ago

I adapted the rest of the page to short names only and checked all other pages for occurrences of fully qualified names (found none).
