I am frustrated with my lack of progress in learning about, and using Linux. The main reason for this is because I've had so much trouble trying to figure out how to keep my system fully patched! I've got a fresh install of RH 9.0, and would just like to know exactly where to go / what to do, in order to get it completely up to date with patches/updates. I need to do this before I start spending time on my system, because I am a paranoid security freak.

I read _seemingly_ conflicting things everywhere I turn -- RHN is free, RHN is not free, RHN is free as a demo, but not for EOL'd RH 9.0, use YUM, use APT, etc. etc. etc.

Please , someone suggest to me the best way for me to get this machine patched, and keep it patched going forward! Obviously, my Linux knowledge is elementary at best, so please, keep it simple (if possible). ; )

Extremely grateful for your assistance,
bert
