ping (1983) command is available in almost all operating systems. The command-line options of the ping utility and its output vary between the numerous implementations. Options may include among others:

  • Count of tests: (-c)[1] (Linux and macOS), (-n Windows)
  • Size of the payload
  • Limits for the number of network hops (TTL) that probes traverse

Timing options:

  • Timeout for exiting: -t (macOS), Linux not implemented.
  • Interval between the requests -i (macOS)
  • Time to wait for a response (-W) miliseconds for macOS and seconds for Linux

Output format:

  1. Review source code of different ping implementation:
  • Use nmap for ping a full subnet: nmap -sn 192.168.0.*
  • Windows:
    • netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow
