1918: ping (Acronis Linux Command)

Sends ICMP ECHO_REQUEST to a network host

The ping command uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or a gateway. ECHO_REQUEST datagrams (pings) have an IP and ICMP header followed by a struct timeval and then an arbitrary number of pad bytes used to fill out the packet.

Syntax:

  • ping [OPTION]... host

Options:

  • -c COUNT Send only COUNT pings
  • -s SIZE Send SIZE data bytes in packets (default=56)
  • -q Quiet mode, only displays output at start and when finished

Example:

$ ping localhost
localhost is alive!
