DNS resolves but not able to surf the web

[mrdurex]

I test my DNS server with nslookup and dig tools and resolves any name I put (for example: "dig yahoo.com") and get an answer. But when I open a web explorer, nothing happens, just i'm able to access my server web page so!! I don't know what's wrong.

I have a Fedora Core 7 install and a BIND DNS Server BIND version 9.4.2, under chroot.

Any help?

Do you have it configured as your name server?

 

[mrdurex]

Yes I do! I think so. Meaning what, if has all configuration set up and running.

Because what I got is, all the zones and forward zones too. All configured

Or is it in the client machine?

The client machine has the IP of my DNS server, in the DNS section, so I think everything is setup correctly.

 

[brianinms]

What about trying a lookup from the client?

 

[mrdurex]

From the a Ubuntu client this is the output. Using DIG

And this is with nslookup but in Windows

nslookup on yahoo

C:\Documents and Settings\Usuario>nslookup yahoo.com

*** No se puede encontrar el nombre de servidor para la dirección 192.168.10.100

: Non-existent domain

*** Los servidores predeterminados no están disponibles

Servidor:  UnKnown

Address:  192.168.10.100



Respuesta no autoritativa:

Nombre:  yahoo.com

Addresses:  216.109.112.135, 66.94.234.13

And on My Server

C:\Documents and Settings\Usuario>nslookup fedora.cr4i.int

*** No se puede encontrar el nombre de servidor para la dirección 192.168.10.100

: Non-existent domain

*** Los servidores predeterminados no están disponibles

Servidor:  UnKnown

Address:  192.168.10.100



Nombre:  fedora.cr4i.int

Address:  192.168.10.100

So I don't know what is happing is everything looking good

What do you think.

 

[lhuegele]

Are you able to access websites by their IP address? If not, then it looks like you have an issue that is not related to DNS.

 

[mrdurex]

No I can not access website by their IP. So what do you think It would be???

 

[mrdurex]

Here is an output

C:\Documents and Settings\Usuario>ping 69.147.114.210

You don't have the correct default gateway on the workstation perhaps.

 

[mrdurex]

ok thanks i'm going to check, but the gateway it's good so I don't know.

Thanks anyway!

 

[lhuegele]

It could be many things - you could have a bad port on your switch - you could have a short connection between your switch and the location of the machine, but the problem is sounds like a network connectivity issue.

The wrong gateway setting would also cause a problem.

Good luck,
