For a while now I've used a Yubikey Neo as a PIV card to authenticate to my public facing hosts. This is fairly straightforward but requires a host with OpenSC on it. In my .profile I have a function called add_smartcard which will add the PIV driver to the ssh-agent. This means I actually authenticate with the key that was generated in the Yubikey and not my password.

Recently I had a rental VW with the fancy new radio in it and I figured I'd give CarPlay a shot.

Welp.

I've been stewing about this for a while and have not yet found an alternative so this is part rant part dear lazyweb plea.

For a long time now the core of my ad blocking strategy has been squid and privoxy running on my OpenBSD routers. Mobile devices VPN into the network and receive a proxy.pac which routes all traffic to these proxies which reject connections to known ad hosts. With the growing adoption of HTTPS (thankfully) privoxy is becoming less and less useful so I have been trying to find better ways to block ads at the networking level.

iPictureFrame and XCode

I know I'm not 'average' when it comes to my opinions about technology. I imagine this has to do with growing up with technology that was much more simplistic than it is today. Compared to modern software and hardware the NEC PowerMate 286 running DOS 6.0 that I learned to program on was extremely simple. Not that it wasn't powerful, but it didn't have any designs to hide things from you. You had access to the hardware directly, and all the memory, and all the peripheral I/O space. You were able to completely control the system, and even understand exactly what was going on.

UniFi Switches in the NMS

Since I installed the first bits of the Ubiquiti UniFi family of products in my network I have been impressed. They have never failed to meet my expectations. I have written several articles about some rather advanced configuration and implementation details:

UniFi Security Gateway in the NMS

A couple days ago I wrote a bit about setting up a new Ubiquiti UniFi Security Gateway, and after living with it for a bit I have a few additional notes.

Background

I have several physical locations linked together with VPN tunnels. The central VPN server runs OpenBSD with iked(8). I also have several roaming clients (iOS and macOS) that terminate client access tunnels to this system so I am loathe to make breaking changes to it. The site to site tunnels run a gif(8) tunnel in IP-over-IP mode to provide a layer 3 routable interface on top of the IKEv2 tunnel. My internal tunnels run ospfd(8) and ospf6d(8) to exchange routes and my external site to site tunnels run bgpd(8). Most of my internal sites use OpenBSD as endpoints so configuration is painfully simple, however in my office at work I have been using a MikroTik RouterBoard RB951-2HnD. This has worked well enough but lately it has been showing its age, randomly requiring manual intervention to re-establish tunnels and flirting with periods of unexplainable high latency.

I enabled HTTPS on this website just under a year ago. If you follow my blog you know that this is a static website, and since there appears to be a bit of an uproar in the web community over HTTPS right now I figured I'd simply weigh in.

I had occasion today to install some updates on one of my macOS systems and found myself inconvenienced by a number of applications adding a pile of dock icons without asking. I don't keep much in the dock on my systems preferring to use clover+space to launch applications and I don't think I have touched the dock layout in literally years at this point so I went searching for a solution.

It seems like the blog is turning into an alternating stream of screaming about things Apple is doing wrong and gushing about how great the UniFi line of products are from Ubiquiti... I have a back log of ideas for things to write about other than those it just seems like life keeps getting in the way and and out the other end either a rant or praise just naturally flows.

Seriously, It Isn't a Problem

There has been a bunch of discussion around the 'revelation' that a software update to the iPhone was purposefully slowing older phones. While I believe that they should have been more transparent to users about what was happening, perhaps even adopting the UI from the MacBook for when the battery has aged and requires replacement (I had to do this about a year ago on my 2011 MacBook Pro, macOS will toss a little ! by the battery icon and of course System Report will give you further information).

I run UniFi to manage my various Ubiquiti access points, now across multiple sites and I try to setup everything with HTTPS only and with certificates signed by my internal CA. I followed for the instructions provided by Ubiquiti for UniFi back when I installed it.

I'm not currently subscribed to Patreon largely because when money on the Internet is concerned I have a long wait and see what happens cool down. There are a lot of Internet start ups that come and go like a flash in the pan and a lot that get bought quickly and morphed into something else. If you are going to have some way to charge me money, I need some stability. I have no problem being an early adopter, as long as you don't have a link to my bank account or credit card (even through a third party).

Summary

A while back I posted an initial review of iOS 11 and a follow up along with a what I admit was a bit of a rant about a beta of iOS 11.2.
