[Info-vax] SSH access to EISNER (DECUServe) has changed

I have also created a more modern ecdsa host key for SSH on EISNER. The 
old RSA host key is still there, but recent releases of Linux will 
report that the host key has changed, and you can accept the new key or 
continue to override that to use ssh-rsa, as shown on the web page:

https://eisner.decus.org/online/ssh

With the new ecdsa key, you are no longer required to specify 
"-oHostKeyAlgorithm=+ssh-rsa" on Linux, etc.

To show you what to expect, here's what I saw when I connected from a 
Linux box for the first time and did not specify the rsa key:

     hunter at zaius:~$ ssh -p xxxxx goatley at eisner.decus.org
     The authenticity of host 
'[eisner.decus.org]:xxxxx([148.51.202.51]:xxxxx)' can't be established.
     ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
     This key is not known by any other names
     Are you sure you want to continue connecting 
(yes/no/[fingerprint])? yes
     Warning: Permanently added '[eisner.decus.org]:xxxxx' (ECDSA) to 
the list of known hosts.
