Resolving slackbuilds.org... failed: Temporary failure in name resolution.
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.
