Testing The Path From A Computer To The Internet; Using Ping On A Macintosh - SMC Networks D3CM1604V Administrator's Manual

Testing the Path from a Computer to the Internet

After verifying that the path between your computer and EMTA is working properly, use the
following procedure to test the path from your computer to the Internet.
To test the path using ping from a Windows PC:
1. From the Windows task bar, click Start and select Run.
2. In the Open field, type cmd and click OK. A DOS command window appears.
3. At the > prompt, type ping -n 10 IPaddress where IPaddress is the IP address of a
remote device (such as your ISP's server) or Web site (such as www.yahoo.com).
4. Press Enter. If the path is working, a reply similar to the one in the previous section
appears. If you do not receive replies:
Confirm that your computer has the IP address of the EMTA listed as the default EMTA.
Ÿ
If your computer's IP address is obtained automatically through DHCP, this information
will not be visible in your computer's Control Panel. Verify that the EMTA's IP address is
shown as the TCP/IP default EMTA.
Check whether your computer's network address (the portion of the IP address specified
Ÿ
by the netmask) is different than the network address of the remote device.
5. When you finish, type exit at the command prompt and press Enter to close the window.

Using Ping on a Macintosh

To ping on a Macintosh:
1. Click on Go > Applications > Utilities.
2. Click on Network Utility, and then click the Ping tab. A page similar to the one in Figure
5-5 appears.
3. In the first field, enter the IP address you want to ping.
4. Using the options below the field, select an unlimited number of pings or send a specific
number of pings.
5. Click the Ping button. If you receive:
reply from..., the destination IP address was contacted successfully.
Ÿ
request timed out, the destination IP address was not contacted successfully.
Ÿ

Ÿ
address. Change your IP address to communicate with the destination address.
