Hi,
You might try setting the HOSTALIASES environment variable to point to a file that maps short names to FQDN's. See the hostname(7) and gethostbyname(3) man pages for more detail. However, in my experience this only works if nscd is not running, and I don't know if it would address your particular use case.

I have an ssh login on a hosting service where the hostname of the

qnhjuc5h8w3s@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
So when I connect I get a very long "<name>'s password:" which I find
rather distracting, not to mention that it doesn't really tell me what
I'm logging into.
I know I can set alternative (shorter) host names by using 'Host'
sections in my ssh config file so that I can 'ssh <shorter name> to
connect but is there any way of adding alias 'HostName' entries?
I know I could add shorter names to /etc/hosts but this would only
work where I have root access and is less easy to manage. I have a
common/shared ssh config file that I use across most of my systems and
thus a change to that would be the nicest way to do it, if it's
possible.
