Verifying network connections

At times, you will need to verify if a dome or computer is being recognized (communicating) with the network.
A simple way to do this is to PING (Packet InterNet Groper) it. Pinging a dome or computer tells you if its
domain name or IP address is accessible. The ping command sends a message to the address and waits for a
reply. If the reply returns without an error message, then you know to look elsewhere for the cause of the
problem that you are troubleshooting.
To verify that a dome or computer is being recognized by pinging it:
1. At the computer's desktop, click Start, click Run, type command, and click OK.
2. Obtain the dome's or computer's IP address (Figure 30) by typing ipconfig (no space) in the black
DOS window at the C:\> prompt and pressing Enter.

3. Ping the dome or computer (Figure 31 on page 55) by typing ping yourIPaddress at the C:\>
prompt and pressing Enter.
In ping -l 1500 yourIPaddress, the -l is a hyphen and lowercase L and the 1500 is the
standard packet size used by GE Security products.
If the dome's or computer's Internet connections are correct, all packets contained in the message will
show as having been sent and received (Figure 31 on page 55). If you are troubleshooting a specific
issue, return to
If an error message is returned, first check the address that is programmed for the dome. If that wasn't
the error, then have your system administrator check the network connection to the dome.
