How
to perform a ping?
Here's how to perform a ping:
- In Windows
2000/NT, click on the Start button (usually located in lower-left
corner). If you're on Unix, skip to step 3.
- Select Programs
-> MS-DOS Prompt (may be called Command Prompt in Windows NT).
- At the prompt,
type ping domainname.com.
This will send 5 ping packets to the address specified, such as
domainname or ipnumberofserver.
A successful ping to www.yahoo.com would look like:

C:\> ping www.yahoo.com |

A ping with problems would hang at the "PING ....: 56 data
bytes" line. Either there is a network problem or the address
itself is down. Give the ping a few seconds to return packets. Poor
network conditions
will slow responses or make responses impossible. Given enough time,
you may see error messages like "Host is down" or "No
route to host". That means the host is unreachable at the
present time. You may also want to perform a traceroute,
as outlined in the previous FAQ.
