ChorusOS 4.0 Network Administration Guide


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

$ rsh target ping is alive

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

$ rsh target ping
no answer from

Note that ping does not support any options.
