I'm currently hand-held by data center technicians with regard to running my servers, but I'm thinking of branching out, and I'm wondering what I need to know.
Some things I understand I should be aware of, but not sure exactly how I should be aware of them:
- Checking log files, specifically security logs
- Keeping my system software, specifically the kernel (and others?) up to date
I'm basically wondering what your favorite little tip which you think every server operator ought to know, but many, if not most, don't.
