2.12.2 Making a Check Using a Loop-Back Address
A loop-back address is returned before it reaches the network PCB; therefore, executing
PING using it will enable a check on the TCP/IP settings made on the machine.
1) Enter the loop-back address (127.0.0.1) in the PING field.
• If ‘NG’ is indicated, check the TCP/IP settings of the machine once again, and execute
PING once again.
• If ‘OK’ is indicated, go to 2.12.3.
2.12.3 Making a Check Using a Local Host Address
The local host address is the IP address of the machine, and executing PING using it will
enable a check on the network PCB (it is retuned after it reaches the network PCB).
1) Enter the IP address of the machine in the PING field.
• If ‘NG’ is indicated, perform the following check/correction, and execute PING once
again:
a. If the IP address of the machine is wrong, check the IP address settings made on the ma-
chine once again, or find out if the IP address assigned to the machine is correct or not
by consulting the user’s system administrator.
b. If the network has faulty connection, check the connector of the network PC for connec-
tion.
c. If the network PCB is faulty, replace the network PCB.
• If ‘OK’ is indicated, suspect a problem in the user’s network environment; report to the
user’s system administrator, and ask for corrective measures.
