B.2 Diagnosing Problem using IP Utilities
B.2.1 ping
Ping is a command you can use to check whether your PC can recognize other
computers on your network and the Internet. A ping command sends a message
to the computer you specify. If the computer receives the message, it sends
messages in reply. To use it, you must know the IP address of the computer
with which you are trying to communicate.
On Windows-based computers, you can execute a ping command from the
Start menu. Click the Start button, and then click Run. In the Open text box,
type a statement such as the following: ping 192.168.1.1
Click [OK]. You can substitute any private IP address on your LAN or a
public IP address for an Internet site, if known.
If the target computer receives the message, a Command Prompt window
displays like that shown in Figure B.1.
Figure B.1. Using the ping Utility
If the target computer cannot be located, you will receive the message “Request
timed out.”
Using the ping command, you can test whether the path to the SL6000/SL6300
is working (using the preconfigured default LAN IP address 192.168.1.1) or
another address you assigned.
You can also test whether access to the Internet is working by typing an external
address, such as that for www.yahoo.com (216.115.108.243). If you do not
know the IP address of a particular Internet location, you can use the nslookup
command, as explained in the following section.
From most other IP-enabled operating systems, you can execute the same
command at a command prompt or through a system administration utility.
