PING
Test a network connection - if successful, ping returns the ip
address.
syntax PING [options] destination_host options -w timeout Timeout in milliseconds to wait for each reply. -i TTL Time To Live. -v TOS Type Of Service. -a Resolve addresses to hostnames. -n count Number of echo requests to send. -t Ping the destination host until interrupted. -l size Send buffer size. -f Set Don't Fragment flag in packet. -r count Record route for count hops. -s count Timestamp for count hops. -j host-list Loose source route along host-list. -k host-list Strict source route along host-list. destination_host The name of the remote host
A response of "Request timed out" means there was no response
to the ping attempt in the default time period of one second.
If the latency of the response is more than one second. Use the -w option on
the ping command to increase the time-out. For example, to allow responses within
five seconds, use ping -w 5000.
A successful PING does NOT always return an %errorlevel% == 0
Therefore to reliably detect a successful ping - pipe the output into FIND
and look for the text "TTL"
Note that "Reply" in the output of PING does not always indicate a positive
response. You may receive a message from a router such as: Reply from 192.168.1.254:
Destination Net Unreachable.
Four steps to test an IP connection with ping:
1) Ping the loopback address to verify that TCP/IP is installed and configured
correctly on the local computer.
PING 127.0.0.1
2) Ping the IP address of the local computer to verify that it was added to
the network correctly.
PING IP_address_of_local_host
3) Ping the IP address of the default gateway to verify that the default gateway
is functioning and that you can communicate with a local host on the local network.
PING IP_address_of_default_gateway
4) Ping the IP address of a remote host to verify that you can communicate through
a router.
PING IP_address_of_remote_host
Examples
PING -n 1 -w 7500 Server_06 PING -w 7500 MyHost |find "TTL=" && ECHO MyHost found PING -w 7500 MyHost |find "TTL=" || ECHO MyHost not found PING -n 5 -w 7500 www.microsoft.com PING -n 5 -w 7500 microsoft.com
PING stands for Packet InterNet Groper
