wget: unable to resolve host address `slackbuilds.org'

when i tried connecting with firefox to access google, I got the following error.

Address Not Found

Firefox can't find the server at www.google.com.

The browser could not find the host server for the provided address.

* Did you make a mistake when typing the domain? (e.g. "ww.mozilla.org" instead of "www.mozilla.org")
* Are you certain this domain address exists? Its registration may have expired.
* Are you unable to browse other sites? Check your network connection and DNS server settings.
* Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

CAN SOMEONE PLEASE HELP ME OUT.

First try the command:

ping 208.77.188.166

It should display something like:

PING 208.77.188.166 (208.77.188.166) 56(84) bytes of data.
64 bytes from 208.77.188.166: icmp_seq=1 ttl=54 time=195 ms
64 bytes from 208.77.188.166: icmp_seq=2 ttl=54 time=187 ms
64 bytes from 208.77.188.166: icmp_seq=3 ttl=54 time=193 ms

Then try the command:

ping www.example.com

It should display something like:

PING www.example.com (208.77.188.166) 56(84) bytes of data.
64 bytes from www.example.com (208.77.188.166): icmp_seq=1 ttl=54 time=192 ms
64 bytes from www.example.com (208.77.188.166): icmp_seq=2 ttl=54 time=189 ms
64 bytes from www.example.com (208.77.188.166): icmp_seq=3 ttl=54 time=195 ms

If the first command works and the second command displays the error it means that you haven't valid DNS server registered in the file /etc/resolv.conf and you should add to that file something like:

nameserver 208.67.222.222
nameserver 208.67.220.220

On the page http://wiki.linuxquestions.org/wiki/Wvdial I found such tip:

Quote:

In Slackware 10, I noticed wvdial wrote DNS configuration on /etc/ppp/resolv.conf while reading /etc/resolv.conf. This prevented DNS from working. Copying /etc/ppp/resolv.conf on /etc/resolv.conf solved the problem.

You can also check your routing table:

route

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
isp             *               255.255.255.255 UH    0      0        0 ppp0
localnet        *               255.255.255.0   U     0      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         *               0.0.0.0         U     0      0        0 ppp0

If default doesn't point ppp0 use two commands:

route del default
route add default ppp0

@ w1k0

The post #2 you did helped me out a lot. Was true: I had to edit resolv.conf because there was no DNS address there.So, thanks.

We are facing the same issue with WVdail on yocto . WVdail up command works get the IP address after successful connection but ping or any internet-based task in not working. We think that we have an DNS issue can you provide us how to check if we have DNS setup correctly

You need to open your own thread for your own question; past that, this thread has been closed for TWELVE YEARS. Additionally, the solution to this is already posted in this thread...did you read/understand/follow those instructions?
