Disclaimer
The information on Frank Line Tech is provided for general and educational purposes.

Technical guides and commands
Most of what's here involves running commands, editing configuration, and changing security settings on systems you control. Those actions carry real risk: a firewall rule can lock you out, a config change can take a service down, and a hardening step that suits one setup can break another.
Everything published here is tested before it goes out, usually on a throwaway server. That's not a guarantee it's safe on yours. Before running anything from this site on a system you care about: understand what a command does, have a backup you've actually restored from, and where you can, try it somewhere disposable first. You run these steps at your own risk, and Frank Line Tech isn't liable for damage, data loss, downtime, or lockouts that result.
None of this is professional security, legal, or financial advice. For a system where the stakes are high, get advice specific to your situation.

Affiliate links
Some posts contain affiliate links, and a purchase made through one may earn a commission at no extra cost to you. Recommendations are based on actually using the thing, and the affiliate arrangement never changes what gets recommended. Full detail is on the affiliate disclosure page.
