confusion about installing/using git; how to undo
- by dan
I'm very new to ubuntu so I'm sure this is a dumb question.
I wanted to install some source code that was on git. Don't really know what that means, I've never used git before, but I figured it was time to learn so I first installed git. Next I tried to clone the git directory of the software I want to install. I got a message saying "the authenticity of IP:IP:IP:IP can't be established". I went ahead and ended up with another message saying warning such and such will be added to known hosts. I went ahead and it said something about hanging up on the connection.
After searching the internet for awhile I realized I didn't need git to install the software but now I have it installed and have added some host to some file or another. I'm concerned I've created some security issues I need to fix.
I know this is stupid but can anyone help me undo what I've done, or better understand what I've done. Did adding a git project open up my system? Beyond that can anyone tell me how git works. Everything I've found assumes I know stuff that I don't yet.
Thanks.
Dan
