Scary to see how many login attempts there are with the lastb command on a standard Linode server - I'm glad I've got it all locked down with public-key only access!

[@ankersman]

Me too. I was shocked!

[@Felix-ve9hs]

Good documentation and easy to understand log files are absolutely crucial for troubleshooting, using "man *" and "tail -f /var/log/*" for example is something I really miss in the Microsoft world...
