Hello Michael,

I'd like to take a step back and ask you to check few things in order, so
we'll have better understanding of what's going on.

First,
On our servers I see there is one ssh public key configured for you. Please
double-check on your computer that the fingerprint matches the following:
    e8:[...]:72:b7 
using
    ssh-keygen -l -f ~/.ssh/id_rsa.pub


Second,
Read-only CVS connections to savannah do not use SSH at all (that is, using
anonymous cvs in pserver mode listening on tcp port 2401).
So I'm not sure what exactly is and isn't working.

Third,
Because we are in the middle of transitioning to new servers for savannah,
there are actually few different hosts that provide SSH access.

Can you please try to connect with SSH to the following two hosts:

    $ host vcs.savannah.gnu.org
    vcs.savannah.gnu.org has address 208.118.235.72
    $ ssh address@hidden

and

    $ host vcs0.savannah.gnu.org
    vcs0.savannah.gnu.org has address 208.118.235.201
    $ ssh address@hidden
 
And tell us what are the results ?

If your SSH key is working, you should see the following message from both
servers:

     Interactive shell login is not possible for security reasons.
     VCS commands are allowed.
     Last login: Wed Dec 28 04:58:11 2016 from X.X.X.X
     You tried to execute: 
     Sorry, you are not allowed to execute that command.
     Connection to vcs.savannah.gnu.org closed.

If you SSH key is not working, then on 'vcs' you should see immediately
the message "Permission denied (publickey).",
but on 'vcs0' you will be asked for a password (which will never be
accepted).

To emphasize:
if you are asked for a password, it means you key is not working - password
logins to savannah's SSH are not supported.


Lastly,
You've mentioned you have been using 'scp' to store files on
'download.savannah.gnu.org' and you've been using a password to login - can
you confirm this is what you meant, and it has worked for you in the past?
I'm very surprised to hear this is working - password-based SSH logins should
not be working on any savannah server.

regards,
 - assaf
