And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

OK this is my problem, since yesterday I have no access to any other web page except google.
This is not cache, because every link I click on the google site works (google native links, not the search results). For any other website either via the search result or by typing the address it gives a "host not found" error.
This happens on all browsers, firefox, links (terminal browser), opera.
Every other computer (3 in total) in my home network works perfectly.
I use a consumer Linksys DSL router (BEFSR41), so there is no fancy firewall nor any other exotic settings like custom IP tables or Access Control Lists.
The 3 other computers all have a static IP address.
The machine that the problem is on is a Asus m6ne laptop.
I use Debian Sarge with a custom 2.6.11-5 kernel
I have tried a static IP address on this laptop as well as using dhcp
(dhcp offers are given by the router within the specified range), both give the same result.
Until yesterday everything worked fine on the school network
For now I have found a unsecured wireless network in my neighborhood which I am using right now.
All the symptoms have the characteristics of a virus, except that this is a linux box and not windows. I checked for rootkits, none were found.
I hope anyone can help me with this.
Thanks in advance
One issue I can think of is that your DNS is screwed up. It already had the google IP on its cache and thats how you are connecting to google.
but it cannot lookup the other web sites ip and hence the problem.
Thanks very much for the quick response
You were right.
The DNS server at my provider was not being resolved properly by the router.
This in combination with DHCP instability of the router was probably the reason for the problems.
I upgraded the firmware of the router, which solved the DHCP thing and it works again.
