while i telnet the host, response with:
login: -h for super-user only.
then connection closed by foreign host.

It may be due to incorrect settings in any of /etc/login.* (login.defs, login.allow,...)

Check them, they're almost always full of comments to guide you, so there should be no problem.

If that doesn't help, you'll have to be a bit more precise.
