Hi guys,
i think, that we have found an issue in the config "sshd_config".
The correct way is, to set AllowUsers in the config like this:
> AllowUsers root at 10.10.10.10 user1 at 20.20.20.20 user2 at 30.30.30.30
In our case, users were separated with a comma. Our hoster has not
followed the correct syntax.
After a reload of the ssh service no error was displayed, and the hoster
thought that configuration was correct.
After a reload with the wrong syntax in config file, the service should
issue an error and should not reload!
Server:
Ubuntu 10.04.3 LTS
