• Examples:
  • pf.conf
  • inet-filter
• Man pages:
  • FreeBSD:
    • fail2ban(1)
    • ifconfig(8)
    • pf.conf(5)
    • pfctl(8)
    • resolv.conf → resolver(5)
  • Debian:
    • fail2ban(1)
    • hostnamectl(1)
    • hosts(5)
    • ip(8)
    • nft(8)
  • CentOS:
    • Unfortunately, the CentOS project has decided to not publish it's manual pages online.
      Your best choice for finding online information about CentOS commands would be the links for Debian above,
      or a project like The Linux man-pages project or Linux man pages @ die.net.
      Keep in mind that paths to files and directories in those documentations
      may differ from those on CentOS.
      Obviously, the CentOS man pages are available at the CentOS command line.
