Currently not possible

Sunday, October 12th, 2014

On Thursday 9th, after weeks of low-level frustration at having to press “close” on every login, I sent a complaint to Barclays asking them to stop asking me on every single login to switch to paperless statements with a dialog box that has only two options: This morning they replied: Please be advised that it […]

“My IP is blocked by a repressive regime, can I have a different one?”

Sunday, July 7th, 2013

I asked this question on Twitter yesterday and got a wider range of responses than I expected, although from a limited number of people. So I wondered what others would think. Say you sell virtual machines and a customer says: My service allows journalists and others inside repressive regimes to get their stories out. My […]

Scanning for open recursive DNS resolvers

Friday, January 11th, 2013

A few days ago we unfortunately had some abuse reports regarding customers with DNS resolvers being abused in order to participate in a distributed denial of service attack. Amongst other issues, DNS servers which are misconfigured to allow arbitrary hosts to do recursive queries through them can be used by attackers to launch an amplified […]

Strategies for talking to Labour MPs about the draft Communications Data Bill

Monday, July 2nd, 2012

Dear Lazyweb, I’m thinking of having a conversation, face-to-face, with my MP about the draft Communications Data Bill. I’ve already done some research on the logical and moral reasons why the bill is a terrible idea. I feel pretty confident in how I can articulate those points. My MP is a Labour MP though, so […]

CentOS 6 in a chroot

Saturday, August 13th, 2011

When fiddling with CentOS 6.x in a chroot: If your host architecture is x86_64 but your chroot architecture is i686 then you’ll find that yum update will try to install lots of x86_64 packages, and then fail. That’s because the arch command still returns “x86_64″. You’ll want to use setarch: # arch x86_64 # setarch […]

Domain name as hostname not recommended

Friday, June 10th, 2011

I had an interesting support ticket yesterday. Someone was trying to do an apt-get update via BitFolk‘s apt cache and was ending up connecting to 2607:f0d0:1003:85::c40a:2942, where it was failing to update. This is not a BitFolk IPv6 address, nor is it the IPv6 address of a Debian mirror. Where was it coming from? I’d […]

Mass-setting the default view mode for cacti

Wednesday, May 18th, 2011

Recently it came to my attention that many of BitFolk‘s customers were finding our Cacti install confusing. The main problem was that upon logging in they were confronted with the default graph view – the “Tree View” – and they didn’t understand where they might find the relevant graphs within this tree. Experienced Cacti users […]

Barclays’ strange priorities

Friday, March 25th, 2011

Over the last week I’ve been receiving calls to my mobile from an 0800 number. They’ve been ringing off too quickly for me to catch them, and being as they’re presenting an 0800 number and not leaving a message, I’ve been assuming they’re sales calls that I don’t need to return. Today I caught one, […]

Where are all the low power enterprise SATA drives?

Saturday, March 19th, 2011

It’s a bit annoying that there don’t seem to be many low power SATA enterprise drives. The Western Digital 500GB Green Power RE2-GP ones were good for a while, but then they went end-of-life. The only enterprise Green Power now are the 2TB RE4-GP at ~£160+VAT a go. What do you do at the 750GB […]

Copying block devices between machines

Sunday, March 13th, 2011

Having a bunch of Linux servers that run Linux virtual machines I often find myself having to move a virtual machine from one server to another. The tricky thing is that I’m not in a position to be using shared storage, i.e., the virtual machines’ storage is local to the machine they are running on. […]
