Not finding debian.org with router attached


Hello,
I'm using Debian6, Mint13 and others with a Tenda W306R router meant to just a switch, with wireless disabled. Non of my web browsers will access debian.org via the router but will when connected directly to the modem. There seem to be no problems with any other sites and this problem is quite new. I have reset the router to factory settings but did not help. Have Debian included new security? Is my router falty and how would I tell?

Fred.

Hi,

I probably comes from your router.
Check the is no filter on debian.org IP address.
Have you tried to access directly to debian.org via the IP address ?
You can get the IP address thanks to the "ping debian.org" command.
If it is working with the IP address you probably have a DNS issue.

Can you post the result of the below commands (from a terminal)?
ipconfig /all
cat /etc/resolv.conf

Regards

Shefla,
the results are as follows:


sudo: ipconfig: command not found

the same with ifconfig were,

/all: error fetching interface information: Device not found

the second command gave,

cat: /etc/resolv.conf: No such file or directory

Hope that helps, thanks.

Roy.

Have you launched you commands from a terminal as root (su - root) ?

shefla,
yes, but as sudo not 'sudo su'.
Tried 'ping debian.org' and got '128.31.0.51' plus some more. When I put that address (numbers only) in the address bar it came up with "senfl.debian.org" web site, which appears to be for developers. Maybe it is a DNS issue? Any ideas?

Fred.

Hi Fred,

sudo gives you error maybe because these commands are not part of the /etc/sudoers configuration file.

Could you please try to launch a root session with one of the below command from a terminal ?
> su - root
or
> sudo bash

And then issue below commands:
> ipconfig /all
> cat /etc/resolv.conf

Regards

Try to add the below line at the very beginning of the /etc/resolv.conf file:
nameserver 208.67.222.222
save your changes

Then try to go to debian.org again.

freelinuxtutorials,
I have n't changed /etc/resolv.conf as yet but did try some of your suggestions prior to doing this as I am always reluctant to change this type of file. If it adds any clarity the result on another mechince connected to the same router were:


patti@patti-HP-Compaq-nc6220-PU982ET-ABU ~ $ ping -c5 128.31.0.51
PING 128.31.0.51 (128.31.0.51) 56(84) bytes of data.
64 bytes from 128.31.0.51: icmp_req=1 ttl=50 time=124 ms
64 bytes from 128.31.0.51: icmp_req=2 ttl=50 time=128 ms

Non-authoritative answer:

Name: debian.org
Address: 86.59.118.148

patti@patti-HP-Compaq-nc6220-PU982ET-ABU ~ $


If this helps?

Fred.

Shefla,
sorry for the hesitancy but how would putting "nameserver 208.67.222.222" at the top of this file resolve the problem on 'fred@debian-upna' and why? My understanding of ip addressing is very limited but the above looks like a temporary address that you are writing into a configuration file, would that be the same on another computer (unix based)on the same router?

Fred.

I did try (eventually) putting 'nameserver 208.67.222.222' at the top of the /etc/resolv.conf file by way of gedit but it only generated a long error file in another gedit window. It had no effect on accessing debian.org but left internet access as before.

Roy.
