Notes:

For the curious I live in Edinburgh, Scotland.

I'm a big believer in the benefits of the open source
software. I've written, or contributed, to a large
number of Open Source projects including GNU Emacs,
GNUTella, GoGo, GNUMP3d, MP3Blaster.

Nowadays I guess the most visible thing I do in my spare
time is run a site I created for Debian GNU/Linux system administration:

Validating puppet manifests via git hooks.

It looks like I'll be spending a lot of time working with puppet over the coming weeks.

I've setup some toy deployments on virtual machines, and have converted several of my own hosts to using it, rather than my own slaughter system.

When it comes to puppet some things are good, and some things are bad, as exected, and as any similar tool (even my own). At the moment I'm just aiming for consistency and making sure I can control all the systems - BSD, Debian GNU/Linux, Ubuntu, Microsoft Windows, etc.

Little changes are making me happy though - rather than using a local git pre-commit hook to validate puppet manifests I'm now doing that checking on the server-side via a git pre-receive hook.

Doing it on the server-side means that I can never forget to add the local hook and future-colleagues can similarly never make this mistake, and commit malformed puppetry.

It is almost a shame there isn't a decent collection of example git-hooks, for doing things like this puppet-validation. Maybe there is and I've missed it.

It only crossed my mind because I've had to write several of these recently - a hook to rebuild a static website when the repository has a new markdown file pushed to it, a hook to validate syntax when pushes are attempted, and another hook to deny updates if the C-code fails to compile.

skx-www upgraded to jessie

Today I upgraded my main web-host to the Jessie release of Debian GNU/Linux.

I performed the upgraded by changing wheezy to jessie in the sources.list file, then ran:

apt-get update
apt-get dist-upgrade

For some reason this didn't upgrade my kernel, which remained the 3.2.x version. That failed to boot, due to some udev/systemd issues (lots of "waiting for job: udev /dev/vda", etc, etc). To fix this I logged into my KVM-host, chrooted into the disk image (which I mounted via the use of kpartx), and installed the 3.16.x kernel, before rebooting into that.

All my websites seemed to be OK, but I made some changes regardless. (This was mostly for "neatness", using Debian packages instead of gems, and installing the attic package rather than keeping the source-install I'd made to /opt/attic.)

The only surprise was the significant upgrade of the Net::DNS perl-module. Nothing that a few minutes work didn't fix.

Now that I've upgraded the SSL-issue I had with redirections is no longer present. So it was a worthwhile thing to do.

Subject - Verb Agreement

There's pretty much no way that I can describe the act of cutting a live, 240V mains-voltage, wire in half with a pair of scissors which doesn't make me look like an idiot.

Yet yesterday evening that is exactly what I did.

There were mitigating circumstances, but trying to explain them would make little sense unless you could see the scene.

In conclusion: I'm alive, although I almost wasn't.

My scissors? They have a hole in them.

Some things get moved, some things get doubled in size.

Relocation

We're about three months away from relocating from Edinburgh to Newcastle and some of the immediate panic has worn off.

We've sold our sofa, our spare sofa, etc, etc. We've bought a used dining-table, chairs, and a small sofa, etc. We need to populate the second-bedroom as an actual bedroom, do some painting, & etc, but things are slowly getting done.

I've registered myself as a landlord with the city council, so that I can rent the flat out without getting into trouble, and I'm in the process of discussing the income possabilities with a couple of agencies.

We're still unsure of precisely which hospital, from the many choices, in Newcastle my wife will be stationed at. That's frustrating because she could be in the city proper, or outside it. So we need to know before we can find a place to rent there.

Anyway moving? It'll be annoying, but we're making progress. Plus, how hard can it be?

VLAN Expansion

I previously had a /28 assigned for my own use, now I've doubled that to a /27 which gives me the ability to create more virtual machines and run some SSL on some websites.

Using SNI I've actually got the ability to run SSL almost all sites. So I configured myself as a CA and generated a bunch of certificates for myself. (Annoyingly few tutorials on running a CA mentioned SNI so it took a few attempts to get the SAN working. But once I got the hang of it it was simple enough.)

So if you have my certificate authority file installed you can browse many, many of my interesting websites over SSL.

SSL

I run a number of servers behind a reverse-proxy. At the moment the back-end is lighttpd. Now that I have SSL setup the incoming requests hit the proxy, get routed to lighttpd and all is well. Mostly.

However redirections break. A request for:

  • https://lumail.org/docs

Gets rewritten to:

  • http://lumail.org/docs/

That is because lighttpd generates the redirection and it only sees the HTTP connection. It seems there is mod_extforward which should allow the server to be aware of the SSL - but it doesn't do so in a useful fashion.

So right now most of my sites are SSL-enabled, but sometimes they'll flip to naked and unprotected. Annoying.

I don't yet have a solution..

Moving to Newcastle

Although things are not 100% certain it seems highly likely we'll be moving to Newcastle in five months time.

If I seem distracted/absent/busy over the next month or two this will be a good excuse!
