I have improved the problematic wording somewhat.  I lack the time to rewrite the entire section to be more inclusive of git, hg, bzr, others however.  Patches are always welcome!

Are you talking about this page?

  https://savannah.gnu.org/maintenance/SshAccess/

As you report that is definitely wrong. It is impossible to grep vcs and have it return cvs as it shows.

Thank you for your interest. Would you consider making a documentation patch for it?  Here is a reference.

  https://savannah.gnu.org/maintenance/HowToAdminThisWiki/

Could patches be discussed on the -email is unavailable- mailing list where things are easier to read and reply. Thanks.

Newer ssh gives a direct hint about the exact line that is the mismatched finger and a hint about how to delete it directly.  Is that section even useful anymore?  Should we just delete it?

Offending ECDSA key in /home/rwp/.ssh/known_hosts:91
  remove with:
  ssh-keygen -f "/home/rwp/.ssh/known_hosts" -R foo
ECDSA host key for foo has changed and you have requested strict checking.

Also the name depends upon the exact name you are using to access the ssh:// protocol hostname.  For example it might be cvs but it might be git.  And it might be {cvs,git}.savannah.gnu.org or it might be one of the aliases {cvs,git}.sv.gnu.org.  And where I am listing {cvs,git} there is also bzr, hg, and so forth.  It has many names.

> Also, you may want to include '-Emd5' in that and other 'ssh-keygen -l' commands, because more modern sshs will show unreadable SHA256 fingerprints by default.


Unfortunately -E is a very new option and isn't yet available in most software distribution Stable releases.

In the FAQ page on SshAccess, there is a 'grep vcs.sv.gnu.org', but then the sole output line contians only "cvs", not any "vcs".

Also, you may want to include '-Emd5' in that and other 'ssh-keygen -l' commands, because more modern sshs will show unreadable SHA256 fingerprints by default.

Maybe also change the examples over to use 'git.sv.gnu.org' instead, as that is what most people will be using.

Oh, and as sr #108870 implies, the command 'ssh vcs.savannah.gnu.org' assumes that the username on Savannah and the originating machine are the same, so it would be better to include "username@".
