automount mmcblk devices
[ link: automount-mmcblk | tags: linux usb mmc disk | updated: Tue, 09 Apr 2013 14:26:10 ]
I put my camera SD/HC card into my laptop (running Debian/testing) and it
didn't mount. Usually I would just run the
mount command to get it going:
dmesg | tail mount /dev/mmcblk0p1 /mnt
That unfortunately has some annoyances and I decided to solve this finally.
tunnelbroker vs IRC

IRC not working over HE.net 6in4 tunnel? read on...
I recently switched VPS's (to Digital Ocean) and because my new co-location provider does not come with native IPv6, I had to use a tunnel. Naturally I chose tunnelbroker.net. However, after reestablishing all important services, I noticed that TCP ports in the range 6666-6669 don't work -- not on IPv6 anyways. These are usually used by IRC servers.
I did a bit of detective work on trying to figure out what was going on. Initially looking for solutions on the internet, but all I found were other people having this same problem with tunnelbroker.net tunnels.
HDD -> SDD
[ link: hdd-to-ssd | tags: hw ssd | updated: Thu, 23 Jun 2011 21:28:39 ]
After reading and hearing everyone raving about SSDs for a couple of years it was hard to resists the upgrade.
So I got an Intel SSD 510 120GB to replace my Seagate 2.5" laptop HDD.
The prices in the ~120GB SSD category are pretty close. I chose the Intel based on reading that they have a low failure rate (I was unable to find the soruce when writing this up).
The Thinkpad X61 only has SATA-II; the drive supposedly has better performance on SATA3.
UPDATE: Samat K Jain points out that "the ThinkPad X61 is limited to 1.5 Gbps, even with SATA-II (Lenovo's excuse: power saving, by keeping bus clocks down)". Lots of discussion about that on the net.
how to manually create a 6in4 tunnel
[ link: 6in4-tunnel-script | tags: ipv6 linux script | updated: Tue, 17 May 2011 21:02:56 ]
I'm doing some IPv6 codig for a client and needed to setup a bunch of 6in4 tunnels.
The procedure can be summarized in these steps:
create a tunnel
ip tunnel add mytun mode sit local 22.214.171.124 \ remote 126.96.36.199 ttl 64 dev eth0
give the local end an address
ip addr add dev mytun f8c0::188.8.131.52/64
bring up the tunnel
ip link set dev mytun up
Presentation slides published!

What a busy week!
As the dust of the (extremely) well attended Ottawa IPv6 Summit settles, we are working through some post conference tasks.
I've just updated the presentation page on the site to include the slide decks of most of the presentations. I am still waiting for files from few speakers. You view the ones which are available on the presentation page.
As you may have noticed -- if you were lucky to get in before we sold out -- the talks were recorded. The results of the recordings will go up on our website within a few weeks.
What is IPv6, and why should I care?
[ link: ipv6-why | tags: ipv6 ipv6summit.ca | updated: Sun, 01 May 2011 20:32:20 ]
[ NOTE: this article began as the front page of the IPv6 Summit.ca website ]
Whenever you use the Internet, you are using an Internet Protocol (IP) - a set of rules for communication between computers. Internet Protocol Version 6 (or IPv6 for short) is an upgrade to the most widely available Internet Protocol (version 4, or IPv4). These Internet Protocols are used to assign each computer with an address (called an IP address) that uniquely identifies it on the Web and allows other computers to communicate with it.
Ottawa IPv6 Summit 2011
[ link: ipv6summit.ca | tags: ipv6 ipv6summit.ca | updated: Sun, 01 May 2011 20:32:32 ]
In the summer of 2010 a half dozen OCLUG members decided it would be a good idea to put on an IPv6 conference for Ottawa. I was one of those people!
At the time IANA still had lots of IPv4 addresses, but it was projected to run out in May of 2011. It seemed that no one in Canada was doing anything about it, and people needed to be educated.
And so, the IPv6summit.ca was born.
I am now an IPv6 Sage
Anyway... I've also been learning a lot more about IPv6. Which reminded me that I never finished my IPv6 Certification from Hurricane Electric. I stopped at the Guri level because getting Sage (the top level) meant that I would have had to have a sane domain name registrar.
# whois ipv6summit.ca Domain name: ipv6summit.ca ... Name servers: ns.ipv6summit.ca 184.108.40.206 2001:470:1c:1cb::6:0
Anyway, long story short... I am now a Sage!
It's a Holiday Miracle
[ link: 20101214145558 | tags: wind | updated: Tue, 14 Dec 2010 16:07:24 ]
I just switched to the Holiday Miracle Plan from WindMobile.ca. I thought I'd mention it since it's not advertised, but a fantastic deal. You have to sign up by December 26th, but you get to keep this rate for as long as you are a customer.
In short: it's unlimited-everything for $40/month. It's Wind, so there are no contracts, hidden fees, or strings attached.
ipv6 on your desktop in 2 steps
[ link: ipv6-for-the-lazy | tags: ipv6 debian | updated: Wed, 03 Nov 2010 12:28:54 ]
Some people have been telling me that they "have no time" or "are too lazy" to setup IPv6 on their desktop, but would like to.
Below are 2 easy steps to get IPv6 running on your Debian Linux sytem (shoudl be identical on Ubuntu, and similar distros).
