Updated ssh Key maybe needed by new Debian (was: Re: rsync support)

Marco (and anyone else with ssh access): You may need an updated ssh keypair which is stronger or more modern - whatever is needed by default by current latest debian bookworm. 



If your logins are still not working apparently because of invalid key type, please send me a new public key which uses a current encryption method such as e.g. ed25519 and I will add to your .ssh/authorized_keys.

Yep.



I just noted that I cannot ssh to http://common-lisp.net anymore (offending key).



Can you point me to the instructions to fix this?


Moreover: I have already set up http://gitlab.common-lisp.net with 2FA, but now, it gets me to the "Explore/Projects".  Would it be possible to point to the personal pages instead?



Thanks

It appears the script assumes an rsync daemon listening on TCP port

support this trivially with much improved security properties.



Thanks for the suggestion.

I set this up many years ago so I cannot be absolutely certain but I
suspect that I used rsync the way I did because that is the method that
was documented at the time.



Likewise, I set up a monthly cronjob to backup cmucl and other
      things I have onhttp://c-l.net. Probably been doing this ever since
      rsync was available.

I am open to doing something different if there are viable options
available.



Me too, as long as I don’t have to provide myhttp://c-l.net credentials.
      Some passwordless ssh would be fine. Or other scheme.
