ping

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.

Example 6-5 Checking a Connection with ping

The following example uses the ping utility to check the connection with the system having IP address 129.157.197.1:

$ rsh target ping 129.157.197.1
129.157.197.1 is alive

The example below shows what happens when the host does not respond:

$ rsh target ping 129.157.197.44
no answer from 129.157.197.44

Note that ping does not support any options.
