The ChorusOS implementation of ping(1M), a basic tool for checking whether a network connection is working or not, requests an ICMP ECHO_RESPONSE from the specified host and simply displays "host is alive" if the host responds within 20 seconds.
The following example uses the ping utility to check the connection with the system having IP address 184.108.40.206:
$ rsh target ping 220.127.116.11 18.104.22.168 is alive
The example below shows what happens when the host does not respond:
$ rsh target ping 22.214.171.124 no answer from 126.96.36.199
Note that ping does not support any options.
