PING User Commands
ping [OPTIONS] [ADDRESS]
ping [OPTIONS] [HOST]
PING is used to test the ability to communicate with a specific HOST over
the IP network (Internet). A small packet is transmitted to a destination
which, if it is configured to do so, will reply. The round trip time is
displayed. A HOST may be specified by IP ADDRESS or Domain Name.
By default PING will make 4 communication attempts. This number may
be specified by COUNT.
By Default PING sends a communication every 1 second. This interval
may be specified by MILLIS in milliseconds (1 sec = 1000 milliseconds).
The Time To Live (TTL) specifies "how far" a packet is allowed to
travel. This is in hops and by the standards each router handling
the packet counts as a step. By default TTL is 128. Using a limited
TTL allows you to probe only the local network neighborhood.
After a packet is transmitted the JNIOR waits for a response. By
default if there is not response in 5 seconds the target is declared
unreachable. This timeout period can be specified in milliseconds.
This option validates the JNIOR network configuration. This PINGs
all of the configured addresses for the Gateway, DNS servers, Mail
Server, NTP Server, and SYSLOG Server. This also checks access to
the INTEG website at www.integpg.com which is just a simple way to
confirm access to the Internet.
The Flood option can be used to test communications reliability.
This continually PINGs the target. A "twirly" is displayed (a
sequence of characters / - \ | mimicking rotation). If a response
is lost the twirly is replaced with a period '.' and the test
continues. This provides a feeling for reliability as periods
appear or do not appear during the test. A Ctrl-C key combination
terminates the activity and reports statistics.
The standard implementation of a network stack supports ICMP (Internet
Control Message Protocol) which includes the PING service. Sites wishing
to limit their visibility may disable PING responses.
