Hello, Please forgive me if this is not the place for this type of question, but lead me in the right direction. Recently I had the Idea that in order to learn about security of my computer while on the internet, I decided to learn from those who are also concerned about the security of my system, only in a different perspective. istarted reading about hacking and have seen how easy it would be to get into my own system. I would not be surprised if I have already been hacked on. Any way, on to my question. I recall reading that you can change the names of commands in the shell. For instance you could make ls -l into lsl to simplify things. Well since to hack into a system, you would need to use some basic commands, like ls and cd etc., would you be able to change these commands to a different command (give the command a different name) like cd would become nohack or some other random name. Thus a hacker would not be able to get around in your system because it doesn't know the commands to do so. Now the big question, if you change the commands on your machine, will your machine still recognise the standard commands issued by the other machine to yours? I have a way of expressing a simple idea with too many words for comprehension. Thanks for your patience and help. Ivan
