I'm having problems accessing ssh for the following version , installed
on Solaris 8
OpenSSH_4.2p1, OpenSSL 0.9.8 05 Jul 2005
When i ssh in from my LAN
it does not give me any problems. However when i set up a NAT from an
to this ip and i perform ssh to this external ip, i get the following
error in putty client log
2005-10-10 17:19:27 Keyboard-interactive authentication
also, i get "access denied" from the console and any passwords for any
user account fails.
In addition, 1 thing funny is that i noticed there is this message when
i login via external ip:

Here's my sshd config below, is there anything that i've done wrong here?
# Don't read ~/.rhosts and ~/.shosts files
# Uncomment if you don't trust ~/.ssh/known_hosts for

# For this to work you will also need host keys in

I also added tcp wrappers though, i'm not sure if that's the reason why
the whole thing is failing though cos i can still ssh in without any
As in, i get the prompt except authentication fails when i type in the
Any ssh experts out there who can shed light on this problem? Or is
there some setting i need to set in my firewall to allow other ports
