I managed to get an SSH client working using an SSH pubkey protected by a TPM.Read the rest of this entry »
From a customer’s perspective it’s hard to tell if HSBC UK is some sort of performance art as opposed to a real bank.
I will add more things to this blog post as they occur to me, since this is the first time I’m writing these down in one place some of the many many absurdities are bound to slip my mind.Read the rest of this entry »
These are my notes from setting up Ubiquity wifi access point and router to replace the horrible BT HomeHub 5.Read the rest of this entry »
This is another post in the series of how to protect SSH keys with hardware, making them impossible to steal.
This means that you know that your piece of hardware (e.g. Yubikey or TPM inside your laptop) was actively involved in the transaction, and not, say, turned off and disconnected from the Internet at the time (like in a safe or on an airplane).
What’s new this time is that we can now have a physical presence test on every use of the key. That means that even if someone hacks your workstation completely and installs a keylogger to get your PIN, unless they also break into your home they can’t use the key even while the machine is on and connected. Evil hackers in another country are out of luck.Read the rest of this entry »

If you have BT broadband and want to graph the synced speed and actual use of your broadband connection, and you use the BT provided router (Home Hub), then you can’t use SNMP to get these counters. But you can get the data over HTTP without too much trouble. Here’s some ugly one-liners for doing that.Read the rest of this entry »
These are my notes on how to set up a system securely, in a way that would prevent attackers from being capable of performing an “evil maid attack”.Read the rest of this entry »
I decided to combine these two problems into one solution:
- Modern CPUs are idle way too much of the time. Why have all this computational power if we don’t use it?
- I have these funny old Quake demos that there’s no good way to convert to something playable.
My solution is to convert Quake .dem files to .pov files and render them with POV-Ray.
