I am having issues (I think) regarding users. When I look at /etc/passwd there are 4 users that I think I have created along the journey to learning Linux. How do I clear these and then only establish only one for myself? Are there possibly passwords connected to them? One of the four appears to be one I set as a user (Lance) when I installed FC4 but when I try to use it with my user (password) to log into ProFTP I get a login error.
This may be connected to the fact that when I log into Linux as a normal user and then through the console log in as su I can't use commands such as service. I get bash: service: command not found.
