Internet connection problem, possibly DNS [solved]

[jigarzon]

Hi !

I m having trouble when browsing with firefox... it shows me this message:

 

"www.***.com could not be found. Please check the name and try again".

 

The curious thing is that Konqueror works ok, and Mozilla (which I uninstalled before installing firefox) too...

 

If I enter an IP address instead of the site name, i have no problems, so i think its the DNS config that is wrong...

 

Thanks for any help!!

You could try to see if ping works:

 

ping www.***.com

 

This also uses DNS.

 

Assuiming you get an IP address automagically, you might also want to look at /var/lib/dhcp. This contains a number of "dhclient-*.leases" files (one for each network interface you have). Here's a lump out of one of mine:

 

lease {
 interface "wlan0";
 fixed-address 192.168.1.100;
 option subnet-mask 255.255.255.0;
 option routers 192.168.1.1;
 option dhcp-lease-time 599940;
 option dhcp-message-type 5;
 option domain-name-servers 194.168.8.100,194.168.4.100;
 option dhcp-server-identifier 192.168.1.1;
 renew 4 2005/3/3 15:14:57;
 rebind 1 2005/3/7 00:01:05;
 expire 1 2005/3/7 20:50:58;
}

 

As you can see, this includes the IP addresses of your domain name servers, which may be useful.

What's in your /etc/resolv.conf ?

Thanks for your reply...

I made a "ping www.yahoo.com" and It worked ok...

 

I also opened the dhclient-eth1.leases file and it has the following content:

lease {
 interface "eth1";
 fixed-address 24.232.80.68;
 option subnet-mask 255.255.255.0;
 option dhcp-lease-time 12924;
 option routers 24.232.80.1;
 option dhcp-message-type 5;
 option dhcp-server-identifier 24.232.0.69;
 option domain-name-servers 200.49.156.3,200.49.159.69,200.49.156.4,24.232.0.69;
 option dhcp-renewal-time 6462;
 option dhcp-rebinding-time 11308;
 option broadcast-address 255.255.255.255;
 option host-name "pentium4";
 renew 5 2005/6/3 10:00:38;
 rebind 5 2005/6/3 11:29:29;
 expire 5 2005/6/3 11:56:25;
}

 

Now I think its not a net configuration problem, but firefoxs..

This is my /etc/resolv.conf file...

 

nameserver 200.49.156.3
nameserver 200.49.159.69
nameserver 200.49.156.4
nameserver 24.232.0.69

Those ips where given by my ISP

Long-shot, but you could try switching off IPv6 in firefox:

 

search for ipv6 in about:config and you'll find the correct key.

I ve already tried :(:(

[jigarzon]

I solved it! :D

It has nothing to do with net configuration or DNS... I downloaded these libs:

- libnspr4-1.0.2-6

- libnss3-1.0.2-6

installed them, restarted firefox and done...!!

 

 

Thanks for your replies

Thats very odd, are you using a mandrake packaged firefox?
