SSH error slow login debug1: An invalid name was supplied Cannot determine realm for numeric host address - Solution

debug1: An invalid name was supplied
Cannot determine realm for numeric host address

debug1: Local version string SSH-2.0-OpenSSH_4.3p2 Debian-9etch3
debug1: An invalid name was supplied
Cannot determine realm for numeric host address

debug1: An invalid name was supplied
A parameter was malformed
Validation error

Solution, disable auth from the ssh client (this is a client side error)

vi /etc/ssh/ssh_config
GSSAPIAuthentication no


Or at  the commandline you can add this flag but it's best to permanently make the problem go away like above:

ssh -o "GSSAPIAuthentication no" user@host

After this you should be able to login instantly almost.
