Some time ago I suggested having sshd listen to a different port than 22. I was criticized that this was just a workaround and
didn't really fix the problem at a deeper level, but it worked for me. It's been over a year now and I can not remember having had
one hit since. Before I changed the port I had tens of thousands of hits every single day...
