LUV hardware library
by Russell Coker 16 Jan '13

Firstly should I bring it to the BBQ? Next we need more stuff. The absolute best thing for the hardware library is RAM. This is because adding RAM is a really quick and easy way of making an old system usable again and also because RAM is small and light. ECC RAM for servers would be good too, but please label it really clearly (otherwise it will be mistaken for broken non-ECC RAM and discarded). The minimum speed of RAM that's useful would be DDR-333 AKA PC-2700 and the minimum size is 512M DIMMs, adding small DIMMs isn't a good option because motherboards don't have enough sockets. RAM that is DDR2-533 AKA PC2-4200 or faster is extremely useful, there's a heap of old Core2 Duo and Pentium-D systems out there that can be useful again with some of that. Laptop RAM is REALLY useful, not only because of old laptops needing an upgrade but because printers often take laptop RAM. PCIe expansion cards would be good. PCIe has been out for long enough that surely someone has some old stuff that they don't use. A collection of spare PCIe video cards would be handy and PCIe Ethernet cards would be really good. USB flash storage sticks are also useful and small. If you have some 32M and 64M sticks that you don't use then please donate them (after securely erasing them). One use for those is for MP3 files for car music systems which often don't have a suitable UI for changing albums other than removing one USB stick and inserting another. The Kia Cerato is one vehicle that really benefits from such use. SATA disks are useful. Probably a couple of 40G disks for systems that don't need much storage would be handy to have and some disks >100G for more serious use. As 3TiB disks are cheap nowadays there should be some unused 300G disks out there. SAS disks are really useful as some servers don't work properly with SATA disks. Even small disks can be good, a pair of 36G SAS disks can make for a really useful server. Note that I won't be bringing a lot of disks to meetings. So anyone who wants disks should email me a day or two before the meeting with a request. The same goes for DVD drives. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Yep, another small ISP I've heard of, Smelly Black Dog, offers native IPv6 on their ADSL services. Looks like they only offer a /64 but that should get you by. (At the moment where I work, I'm doing dynamic /56's, and will do static /56's once I teach our customer database to speak IPv6.)

Good practice or not, I'd say very few (this list would be an unrepresentative sample, skewing estimates very much higher than reality). Segmented networks can be a pain for non technical users with today's plug and play (pray?) devices which expect to find each other on the same LAN segment. 73 de VK3JED / VK3IRL http://vkradio.com

Yep, cloned VMs can certainly cause duplicate MAC addresses on their virtual Ethernet interfaces. Haven't had that issue, because I run VMware, and it is good at detecting when you've moved or copied a VM, and recommends you to say "I copied this VM" if you're not sure. I was debugging the MAC address issue over 10 years ago on a mostly Windows network. We had some IP, as well as Novell IPX/SPX, and a couple of Linux boxes, mostly (all?) in the DMZ, which wouldn't have helped with the troubleshooting. I had to logically deduce what was going on, and duplicate MAC addresses ended up being the only logical possibility (which was proved), after checking that the (Windows) DHCP server was working correctly and ruling out other possibilities. 73 de VK3JED / VK3IRL http://vkradio.com

Shouldn't be, but I have seen duplicate MAC addresses in the real world.

Agree, the reasoning is very circular. I'm not convinced either, and I'm sure usage changes down the track will see changes in addressing and routing policies, just as happened with IPv4 over the years. 73 de VK3JED / VK3IRL http://vkradio.com

I purchased sometime back a pair of OCZ 128g Vertex 4 drives under a recommendation from a salesman of long aquantence. While once installed the drive works OK, the first drive installed did some __EXTREMELY__ strange stuff on start up. Effectively delaying the boot up by minutes. Had to switch the system off twice to get it working. So the second drive has been dumped so if anyone wants it to play with you are quite welcome to it. I have since gone with IBM SSD drives although Samsung are getting some good writeups one review saying they actual make there own SSD chips unlike allmost every one else. Lindsay

Telstra Business Broadband (was Internet Direct) says it's >coming soon for their ADSL tails, but it's been that way for a while. Yep, would have thought someone other than Internode would be offering IPv6 by now. Internode IPv6 is rock solid. Only times I notice IPv6 is either if I can be bothered checking what IP I'm connecting to, or when something screwy happens. Had a good one last week. Several people complained a site wasn't working, but I never had any issues. Turned out the site was IPv6 capable, but there was a DNS screwup with the IPv4 RRs, so only IPv4 users were affected, and I had no issues. :-D > > 2.

If my server was part of a money making concern, I'd go this route, but it isn't. At this stage, SixXS via New Caledonia looks like the best of a bad lot for me. :) Latency isn't too severe (35-40 mS from Adelaide and 50 ish mS from my DSL connection here), and their PoP is lightly loaded (6 tunnels, 1 routed subnet). 73 de VK3JED / VK3IRL http://vkradio.com

Or if you live around the WISP where I work at (Southern Highlands region, NSW) you can get native IPv6 as well (just need to pop an extra line into the RADIUS response). Only took me a couple afternoons worth of work to deploy (this is a very small scale setup, mind). (Seriously, deploying IPv6 is drop dead easy. It’s the huge level of ignorance, not technical problems, that is the greatest blocker when it comes to deployment.)

you can also use the 6to4 method which uses a generic encapsulation method and routes to the nearest 6to4 router via ipv4 anycast. Pipenetworks and a few other AU ISPs run these gateways. http://en.wikipedia.org/wiki/6to4 it's also mostly trivial to set up in Linux, esp Debian based ones: http://wiki.debian.org/DebianIPv6#IPv6_6to4_Configuration Before I had native v6, this was my preferred method. Latency, reliability and setup is much better than userspace driven tunnels. It will give a static subnet if your v4 address is also static. However there is no mechanism for ip6.in-addr.arpa delegation.
