sshdcond is a package created by namezero111111
that introduces access lists and control over ssh connections.
I did some fixes and improvements before publishing first release to be sure it will be easy to use by everyone.
With this package you can, for example, deny tcp port forwarding via ssh.
To understand better what you can configure/restrict and how sshd options works, take a look on http://www.manpagez.com/man/5/sshd_config/
