Hacking Linux Server is a complex matter, specially because the meaning of hacking is sometimes non-specific. Is it to use computer programs made by other programmers to compromise security on a vulnerable server or platform and not get caught? Well, people generally consider this script kiddioting (kidding + idiotic) and for a very long time I did too, but nowadays if you can go from base line (ground zero, or whatever you want to call it) to actually having full access (UID 0) on a machine and keep it so that a system administrator cannot detect you, then you must at least have some credit and if you were able to create simple scripts to achieve this, you DID hack something, so it’s hacking!
