Four years ago this month we reported that it was time to get ready for the bigger-scale network addresses called IPv6. In that year, the Internet was reported to have run out of the IPv4 addresses, which was the impetus to create the larger IP numbers. It also seemed like the HP 3000's inability to address IPv6 was going to be one of those sparks to getting migrated off the system.
But despite a lack of resources -- which would have been OpenMPE volunteers -- it looks like IPv6 hasn't hemmed in the 3000 from continued service. Now the open source project called Docker has a new 1.5 release, one that aims to bring these bigger IP addresses to more systems. Open source, of course, means Docker might even be of some help to the 3000s that need to be in control of network addresses.
The IPv6 protocol was among those OpenMPE considered when it applied for its license for MPE/iX source. It was suggested back in 2008 that a contract project might revise the 3000's networking to accommodate the new protocol.
As we surmised four years ago, native support for IPv6 networking hasn't been the deal-breaker some 3000 experts expected. Although HP prepared the 3000 to do DNS service, the vendor didn't build a patch in 2009 to eliminate a security hole in DNS for MPE/iX. That's bedrock technology for Internet protocols, so it would have to be made secure. Much of this kind of routing for 3000 shops takes place on external PC systems today.
Making old dogs do new tricks has been demonstrated on Windows. You can even make an older Windows XP box do IPv6, according to Paul Edwards, a former OpenMPE director who's been a training resource for the 3000 community for decades.
You may have heard the news: the world officially runs out of IPv4 addresses this month. But never fear. IPv6 is here... well, sort of.
Many companies are converting their networks to IPv6 now, and Windows 7 comes with built in support, but what about those who are still using Windows XP? Luckily, it’s easy to install the IPv6 protocol on your XP machine. Here’s how:
1. Click Start | Run
2. Type cmd to open the command prompt window.
3. At the prompt, type netsh and press ENTER
4. Type interface and press ENTER
5. Type ipv6 and press ENTER
6. Type install and press ENTER
This installs IPv6. You can confirm that’s been installed by typing, at the command prompt, ipconfig /all.
You should see an entry under your Local Area Connection that says “Link-local IPv6 Address” and shows a hexadecimal number, separated by colons. That’s your IPv6 address.
Last fall, our contributor and 3000 consultant Brian Edminster said Docker looks like tech that could help put 3000s into the cloud, too. "Docker struck me as an easy mechanism to stand up Linux instances in the cloud -- any number of different clouds, actually," Edminster said. According to a Wiki article Edminster pointed at, Docker is based upon open source software, the sort of solution he's been tracking for MPE users for many years.
Docker is an open-source project that automates the deployment of applications inside software containers, the Wiki article reports, "thus providing an additional layer of abstraction and automation of operating system-level virtualization on Linux. Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting virtual machines."
