there is mutch simpler way to block sshd - just force sshd to ask password in login time, now create connection and let ssh to wait for password.... no one can login with ssh (with or without password) during this wait time.... tested with 1.2.17
Can anyone confirm this? I wasn't able to reproduce this on either 1.2.14 or 1.2.17. I ssh'ed to a host and left that session at the password prompt, and after that I was still able to ssh into that box, both from localhost and from a remote host. A quick ps reveals that a new sshd gets spawned for every connection.
