====== Most important tools ======
  - brain, brain, brain -- I couldn’t stress it out further or "a fool with a tool is still a fool"
  - fundamentals, you have to certain about network and system fundamentals
  - listen to your client
  - [[sysadmin:lookatyourlogs|LookAtYourLogs]]
  - ping
  - telnet
  - traceroute
  - nmap
  - nessus
  - perl

There is no magic problem solving tool. Most of the time i use very simple tools and fundamental know how.
