I'm curious to know what, if anything, appears in /var/log/messages and 
/var/log/secure when you attempt to ssh in, as well as what appears when you 
successfully scp in.

Also, the fact that you're running sshd on a non-standard port implies that 
you've edited /etc/ssh/sshd_config.  Could you try the default sshd_config, just 
for comparison?  It's entirely possible that you're doing something that should 
be valid, but that some other security policy (PAM, SELinux, etc.) doesn't 
correctly handle in the default configuration.
