I have a server running Debian 6.0 with logcheck installed. Yesterday ago, I received this message: Jan 19 19:15:10 hostname sshd: Authentication tried for root with correct key but not from a permitted host (host=4.red-2-140-77.dynamicip.rima-tde.net, ip=184.108.40.206).

I have the problem that sshd somehow ignores a match block. The configuration of sshd is kind of basic. You can find it here: http://pastebin.com/bNUYhQnx My goal is that every user except root should only be able to login with pubkey authentication. But even with the configuration mentioned above I’m still able to login with a user which is not root only with a password. Version of sshd is: OpenSSH_5.5p1 Debian-6+squeeze2, OpenSSL 0.9.8o 01 Jun [...]Continue Reading »

The simple solution would be to provide my external IP address and forward the incoming traffic from the router to my machine. However, I’m working in a [...]Continue Reading »
