I tried connecting to my new installed Ubuntu 12 server via SSH and I was asked for my password. (I had used "myusername@ipadress" to connect)
After entering the right password a few times (with no luck; access denied) I started getting an error directly telling me that the connection was refused without asking me for a password anymore.
It seems like I have managed to blacklist myself. It has been like this for about 2 hours now, is there a quick solution for this?
