If you’re like me, you have a home LAN filled with various contraptions, computers, mobile devices and the ubiquitous server in the closet. Usually there’s no DNS zone containing your home devices, if anything, maybe a static /etc/hosts entry on your desktop to give a short hostname to your closet server. Otherwise, people just use [...]

I discovered today there’s a way to bring IPv6 connectivity to your iPhone, even if you don’t have v6 wifi nor v6 cellular data. There’s a Cisco AnyConnect client for iPhone which speaks SSL VPN (TLS/DTLS) to an ASA. The release notes say “Access to internal IPv4 and IPv6 network resources”. I take this to [...]

My host’s home network is behind NAT, has no 6to4 connectivity and the router squashes IP protocol 41 (6in4). Normally in this situation I’d fire up a Teredo tunnel, but here it’s pretty unreliable. My control traffic to Microsoft’s Teredo server goes to Singapore, and who knows where my closest Teredo relays are. After some [...]

At a last minute urging I went to the Austin “get-Google-to-lay-FTTH” Big Gig party last night. I got to catch up with some of my colleagues from my last job, and met several new people, including (surprisingly) a group of attractive, chatty young ladies who were there as part of the co-”tweetup”. A good time [...]

Since we’re being dragged kicking and screaming into the great scam that is “cloud computing”, I decided to go try it out sight unseen. I’ve wanted a VPS in Singapore with IPv6 for a while, and somebody pointed out that Voxel has a dual-stack cloud offering in Singapore. I punched in my info, hit order, [...]

When you want to encourage search engines to index your site, don’t forget the robots.txt you wrote in 2002 that says Disallow: /. It kinda doesn’t help. Both Google and Bing have some interesting tools to help manage your search listings. Both will tell you the last time you were crawled, errors found, and other [...]

It turns out my problems with IPv6-only Net-SNMP wasn’t a problem with snmpd, it was a problem with selinux. After starting with -Dread_config -c /etc/snmp/snmpd.conf it became apparent:
snmpd[9026]: registered debug token read_config, 1
snmpd[9028]: /etc/snmp/snmpd.conf: Permission denied
snmpd[9028]: /etc/snmp/snmpd.conf: Permission denied
snmpd[9028]: Warning: no access control information configured. It’s unlikely this
agent can serve any useful purpose [...]

I just discovered a horribly annoying problem with the IPv6 firewall in the Airport Extreme. It doesn’t operate as “let these addresses have access to devices on the home network” (the source). It operates as “let the world access X service on this IPv6 address on my home network” (the destination). [...]

Being the annoying IPv6 evangelist I am at work (I turned up our first dual-stack and v6 load balanced “hello world” webserver last week), I wanted more viewpoints of native IPv6 connectivity to play with. Turns out there’s only three or four peeps that sell virtual private server (VPS) with [...]
