Hi!

I've installed a new box with FreeBSD 6.0 (workbench) and cant login
to it by means of ssh from the internal or external network. The box
is installed from the release version, and worked fine using the
console. I also had accessed other hosts form there using ssh. I did
not patch the box in any way, is just the 6.0 release version. I can
not login to that box form a local OpenBSD 3.7 box, a 5.4 box (as
shown below) or using putty 0.57 from the Internet (the putty window
closes after some time without asking me for a password) .

Anybody have and idea of what could be happening?

Thank you in advance,
Mauro

Form a 5.4 Box,

I issue the following command:
