Cant login using ssh; no password prompt

[Mauricio Brunstein]

Hi ben!

Thank you for oyur answer.

The resolv.conf file have this line:

nameserver 192.168.1.1

At this address there is an OpenBSD 3.7 firewall which running a cache
DNS from my provider. When I was using olders versions of ssh from the local
network I had to wait more to the password prompt until I've
configured the /etc/hosts file in the new box. Bun never happened a
situation like this one.

Thank you for all,
Mauro
