ping

check if www.google.com is reachable ping www.google.com

stop pinging after 10 seconds ping -w 10 www.google.com

wait 3 seconds between packets ping -i 3 www.google.com

send only 2 packets then stop ping -c 2 www.google.com

send a packet size of 10 bytes instead of the default 56 ping -s 10 www.google.com

Basic Usage

Use the ICMP protocol to check if a host is reachable: ping

By default ping sends 56 bytes in a packet plus 8 bytes of header, for a total of 64 bytes. This can be adjusted with the size (-s) option: ping -s

Use <CTRL>-c to stop ping.

ping

Send ICMP ECHO_REQUEST packets to network hosts.

  • Ping host:

    ping host

  • Ping a host only a specific number of times:

    ping -c count host

  • Ping host, specifying the interval in seconds between requests (default is 1 second):

    ping -i seconds host

  • Ping host without trying to lookup symbolic names for addresses:

    ping -n host

  • Ping host and ring the bell when a packet is received (if your terminal supports it):

    ping -a host

  • Also display a message if no response was received:

    ping -O host

To ping with 15 packets:

ping -c 15

To ping with 15 packets, one every .5 seconds:

ping -c 15 -i .5

To test if a packet size of 1500 bytes is supported (to check the MTU for example):

ping -s 1500 -c 10 -M do
