Can a router deny access to computers running linux?
« on: May 17, 2014, 09:14:05 AM »
Hi all,
I have a strange problem that makes me think that a router can deny access to the internet for computers running Linux.
Is that really possible???
I have, with 3 different computers (2 laptops and 1 desktop), tried to access the internet. When in Windows (XP and 7) there is no problem, in Linux (and I did try many different distros) I get an ip adress from the router and can ping the beast but cannot go on the internet.
The same laptops, running the same OSes do fine in another office with another router. Also no problem at home with adsl modem/router.

Then I did another test.
I configured a Windows XP box to run Internet Connection Sharing. One network card to the problematic router, the other network card connected to my laptops/ destop running Linux. In that configuration, no problem at all to surf on the internet!

So I am 100pc sure that it is not a laptop/desktop configuration problem.
I do not (yet) know the brand of router. I know it is a router purchases from the ISP (vdsl line).

What do you think, does that exists, routers discriminating Linux in favor of Windows?    :confused:

It may not be the router blocking but poor DNS design.

When your computer gets an IP from the router it normally gets the router IP for DNS. And if the DNS is setup in a way that only works with Windows then pinging an IP will work but a domain name will fail.

So instead try setting your dns on your machines to googles instead of the routers.

8.8.8.8
8.8.4.4

And see if that helps :wink:

Hi Shane,

Thank you very much for your reply. I tried to access the web via the google dns and also some other open dns but to no avail.
It must be something else.
I am out of the office for 3 weeks as of tomorrow so testing will have to wait I am afraid.
But I will post again as soon as I tackle the problem anew.
Thanks again

Ron
