What do you get when you run sshd from openssh-5.9p1 in debug mode (ie
"/path/to/your/sshd -ddd -p 2022")?  You won't even need to connect to
it.

On fedora, I get:


debug2: load_server_config: filename /usr/local/etc/sshd_config
debug2: load_server_config: done config len = 435

which indicates it's working as expected here.

Are you sure you don't still have the old sshd or something else
listening on port 22?  immediately before starting the sshd, do you get
any "LISTEN" states from "lsof -i :22" ?
