 Posted: Tue Dec 07, 2004 5:06 am Post subject: Ping Command Question |
 |
|
G'Day All,
Just a general question. Not really posing any issue with my site, but i am just curious. Everyone is able to view my site fine, which is the best thing. The interesting thing is that when i use the ping command to ping my site (ping www.joeysfc.com), it cannot resolve it, all packets are lost. Does this mean anything? Just curious why it wouldnt be able too. One thing that may be is because i have a script that forwards requests based on URLs, that is, if a url is www.joeysfc.com, it forwards to the page htdocs/joeysfc/index.php, and so forth with other URLs. Would this stop me from being able to ping my address???
Cheers
Mick Koch

Not being able to resolve means that you don't have (properly configed) DNS record for it or you have misconfiged the machine the you try to ping from, but you wouldn't be able to ping any URL then.
If you can resolve if but is get "request timed out" you might take a look at the router/firewall on the server which is likely configed to ignore pings.

Script based forwarding will not affect any ping request as the script-engine will have to read with what URL you want to "enter" the server.
Ping only send a package to an IP address and gets a reply back.
That is unless you have a router/firewall running which ignores ping requests (IP port 7) |

Ah i see, yes the you are correct. It does come up with Request Time Out for all four packets. So in order to allow a ping, i would need to open port 7 on my router?
Thanks for your help.

That depends, if you can ping www.nai.com successfull then you need to open port 7.
Its an normal option in most routers/firewalls, block WAN/ICMP/ECHO requests.
So it might be best to check out the options in your router/firewall before open port 7 the brute way.
If you can't ping www.nai.com then you might need to take a look at your router/firewall from the location are pinging from.
Some routers/firewalls have the option to block everything that you don't explictly open.
Companies normally use that: block everything except 21, 25, 80 and 110. |
