I am ssh'ing into a remote server and then su'ing to root.
The problem is that sometimes, I have not paid enough attention to the console message, and I have accidentally typed in the root password at the command prompt (when for example, I had failed to provide the root password correctly the first time - so su prompt went away).
I remember reading somewhere that a history of commands typed at the console is kept somewhere.
I have 3 sub questions
- Where (which folder) is the file stored?
- Can I edit that file and remove the root password from it?
- Being the paranoid person that I am, I wonder if there is a more secure way of logging into my server - other than ssh (or am I being TOO paranoid?)
My server is running a headless Ubuntu 10.0.4
