I recently setup openssh on an Ubuntu machine. The only type of authentication was using strong passwords (no public key authentication). Now by the looks of my auth files in the /var/log directory, my ssh server has been accessed repeatedly. I have no idea how to find out what was done during these sessions. My first thought was to reformat the drive but I have a lot of time into setting up my current dual-boot setup.

I need from some linux ninjas advice on the best course of action.
