Freebsd jails with iocage

This is small howto for star playing with jails in freeBSD.

Installing kubernetes cluster with wireguard

This is part one of few posts about kubernetes… If you don’t know what kubernetes is, then you probably came here by mistake… I’ll make simple setup, with one master and one worker node, connected by WireGuard VPN (it seems that it still isn’tk finished/stable/tested enough, but should probably be OK for this setup?), using Flannel for semi-automatic network configuration between nodes in cluster. For more info check their github page and kubernetes page about cluster networking.

Revoking certificates and running OCSP responder

If you followed previous posts, you should now have working cfssl configuration and server. All that is left is how to revoke certificates and running OCSP responder to verify certificates.

Setting up CFSSL OSCP and API server with SQLite database backend

If you followed previous post, you should now have working cfssl configuration. Next step is to setup OCSP and API servers for revoking and issuing certificates with REST endpoints.

Setting up CFSSL

I have smartOS server at home with few (dozen) virtual machines, and was thinking that centralized PKI server would be a good thing, so I tried to create my own solution in go, and it worked, in a basic mode, but anything more would be a lot of work… So, my attention was moved to CloudFare SSL toolkit which, at first, looked complicated and too big for my needs… But, in the end I gave it a try.

FreeRadius authentication and authorization with yubikey OTP

I have smartOS server at home with few virtual machines, and was thinking that centralized AA server would be a good thing to have… FreeRadius seemed to be a good solution for my needs, and there are few guides online for integrating yubikey OTP authentication.

Playing with EZ430 chronos watch in OSX

I have Chronos watch from TI for a year now, and I’m using it as a watch, not as a development platform.. :-D
Original battery lasted for more that a year, and three days ago, clock has rebooted and reseted! I tought that it was because of battery, but clock states that battery is at ~85%, and I tried with new battery anyway…

No luck, still reboots. So, I decided that is time to reprogram it! ;-)

Playing with EZ430 chronos watch in OSX, part 2

So, if you followed previous post, you have installed needed toolchain, downloaded openchronos-ng, configured it and build. Now, we need to flash new firmware.
