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 220.127.116.11:
$ rsh target ping 18.104.22.168 22.214.171.124 is alive
The example below shows what happens when the host does not respond:
$ rsh target ping 126.96.36.199 no answer from 188.8.131.52
Note that ping does not support any options.
