In OSX 10.6.xx (Snow Leopard) users who use the Terminal application to SSH into remote servers might experience that the backspace key works as the delete key in some applications (VI, Nano, Pico etc) I have not heard of this happening in any other OS or application, so an easy way to fix this in Terminal configuration on your Mac.

Go to Terminal preferences, select the Advanced tab, and check “Delete sends Ctrl-H”. That’s all it takes to get the “delete” key to work correctly in all applications used in your SSH sessions.
