SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? 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.

I've got a computer running WinXP, with a USB ADSL modem. I want to share this connection with a Linux box (currently Suse 8.2).
I've got them connected via a crossover cable, run the network wizard on XP which has set up IP 192.168.0.1 & netmask 255.255.255.0. On the linux box I've set IP/proxy options as 192.168.0.2 everywhere this is an option in Yast.
I can ping the linux box from XP, but not vice versa. I presume I'm missing something, but don't know what to do now. Any suggestions?
OK, so I half solved the problem - I couldn't ping the linux box because it was going onto standby
Anyway, I can ping both ways - but I can't access the internet from the linux box. Everything seems to be set up OK on the XP one, and the static IP on linux is set to 192.168.0.2, with 192.168.0.1 as the proxy and defailt gateway. I've manually entered my ISP's DNS servers.
I've now removed all proxy entries (guess I was trying too many things )....I can ping any IP from the linux box, but neither Konqueror nor Mozilla download any page - in both cases they halt with the status bar reading "waiting for reply", or similar.

Try: <http://126.96.36.199> - this is the IP address of one of the Google servers. If you try this and get Google, you may have a name resolution (DNS) problem.
That worked - but at a glacial pace. So now I wonder if the problem isn't a physical one with the equipment I've got. How can I test that the network between the two boxes is running cleanly, beyond pinging, before I think of buying new kit? And if that's not the problem, what should I do with the DNS issue (at the moment, the XP box is getting the DNS address automatically, and I've set the Linux DNS as 192.168.0.1 - is this correct?)
Changing to the external DNS doesn't help. And the thread that PEACEDOG linked to isn't dealing with the same problem - there it was getting the crossover working to ping both ways.
However, I've run pings for half an hour each way across my crossover, and I'm getting a packet loss of 40-50%, which I'm guessing could be my problem - if so, is there any possible explanation for this, other than hardware?
Um, what's the brand of network card on the Linux box? I had a similar problem a couple of years ago with DLink cards using the via-rhine.o driver. Under heavy traffic, packets started vanishing. Put the NIC in a Windoze machine, no problems. Then I just started using cards with Realtek chipsets and have never had a NIC problem since (touch wood!).
