What problems exactly?  Do you get past looking the site up, or does it
hang once the site has been contacted?  Some ISPs don't carry some sites
in their DNS's, so you can't connect to them without playing around a
bit.

Pinging a site just times the flow of a little packet of data to that
site and back again.  It gives an idea of how slow the route is, and
whether or not the site is actually responding (or even there).

The hostname is the sitename you'll be familiar with.  The host address
is the IP address which uniquely identifies the site on the internet.
When you use any site name, it is looked up on a Domain Name Server
(DNS) to get the IP address.  If your service provider's DNS doesn't
have an entry for a site then your application can't get the IP address
and won't be able to connect.

Packet size is the size of the little 'test bundle' bounced off the site
you specified above.  64 bytes is usually used.  Send interval is how
often this packet is thrown at the site.  1000ms is 1 second, so the
above site is pinged with 64 bytes once a second.  The program is
listening for the return of those packets and is timing them.


>Number of Packets Sent: 7
>Number of Packets Received: 0
>Percentage of Packets Lost: 100%

Your ping program sent 7 packets and got none back so there was 100%
loss.  In this case it means that there is no connection available
between you and that site.  You should get x packets sent and all x of
them received after so-many milliseconds.

>Total Trip Stats:  99999 Minimum / 0 Average / 0 Maximum

This shows the quickest return time (Min), the longest return time (Max)
and the average of all 7.  The 99999 shouldn't really be there - it
suggests a minimum return time of 100 seconds.  Probably the way the
program does its maths doesn't work quite right for zero times, etc.

Does your provider have a support line?  You should ring this if so.  It
may be a modem setting.  I'm afraid I don't really know what it is.  You
should be able to see your own provider via ping.  Get onto them and ask
for support.

Chris
