Today I had a case where a coworker wanted a Linux server to connect to a particular VPN, and we didn’t want to make it use some hacky way like putting a script in /etc/rc.local for it to run on boot. By using systemd we learned how to use it to control connecting to the VPNs, using the OpenVPN client. Steps Install the OpenVPN client Verify the openvpn client is installed Debian/Ubuntu apt-get install openvpn RHEL/CentOS yum install openvpn Get VPN keys, certifiates and configs From your remote host, get the files or zip file that includes your VPN keys, certificates and configs Place the files (unzipping any archives) into /etc/openvpn on your client Configure OpenVPN session In the directory /etc/openvpn copy the .

When getting started with Linux and open source software, running websites was one of the first things I learned how to do. Of course with the way software evolves, I’m still learning new ways to better secure, encrypt and protect web assests. Recently I wanted to build a new project and decided I wanted to use OpenBSD, arguably the most secure operating system out of the box. While years ago I switched to FreeBSD for web and mailserver handling, OpenBSD is just more stringent about how it presents things. There’s more to learn, sure, but that’s all part of the fun. Now, if you look around at normal VPS options like DigitalOcean and Linode won’t allow you to run OpenBSD, but with Vultr (affilate link) you can use any ISO you can point to. They have a $5/month option, but they give you 768M RAM versus the 512M that you get from most other VPS providers for that price. With that decided I ran through the install using their console and was up and running in no time. Now for the fun part, let’s
ssh to the server and setup a very setup a secure webserver!
I’ve wanted to get into tube audio amplifiers for my stereo systems for a long time, so years ago I bought my first ones, a pair of Antique Sound Lab AV-25 monoblocks. One thing that was a bit tricky was to bias the amps, and the units didn’t come with directions, so I eventually got info directly from the company, but could’t find it anywhere online. I’m transcribing them here for my reference and for others, in case they have the same, or similar, amps from Antique Sound Labs.
This is a previously unpublished sketch written on 2007-04-18 of two people talking about the constant state of fear in a nation controlled by the media. Strangely it’s still relevant today. […] “But what about them; what’s the difference?” “What?” “With their outlook on things, everything is just so negative, have we evolved that way?” “You’re telling me you mean we became more negative as a species over 50 years?

UPDATE 02-29-2016 a reader had issues getting this working, and after reproducing his issue I found that the
ssl_cipers HIGH:!aNULL:!MD5;no longer works. Apparently sometime after I wrote this, the HTTP/2 specs were updated, and browsers followed suit. This blog post tells us, “According to the HTTP/2 specification, over TLS 1.2 HTTP/2 SHOULD NOT use any of the cipher suites that are listed in the cipher suite black list, found here” So now, we have to call out another cipher before the blacklisted ones
ssl_ciphers AESGCM:HIGH:!aNULL:!MD5Thanks for the note Elias!
Last week nginx relased mainline version 1.9.5 which features experimental HTTP/2 module. According to the Internet Engineering Task Force “HTTP/2 enables a more efficient use of network resources and a reduced perception of latency by introducing header field compression and allowing multiple concurrent exchanges on the same connection. It also introduces unsolicited push of representations from servers to clients. This specification is an alternative to, but does not obsolete, the HTTP/1.1 message syntax. HTTP’s existing semantics remain unchanged.” You can get an idea of how HTTP/2 is better and faster on this demo page which shows the multiple connections making a significant difference.
TL;DR it’s faster, backwards compatible and the new hotness (obviously).
I’ve written about Bruce Schnier many times before, but this recent comment perfectly captures why we all need to be concerned about our only privacy
In a recent article, the magazine Rolling Stone tries to list the 100 Greatest Songwriters of All Time, and while any list that a audacious will have it’s detractors (and there is much to criticize in this one), it’s refreshing to see the songwriting tandem of Morrissey and Marr getting the props they deserve. Breaking in at #67, the post features some very nice quotes from Marr about Morrissey, and a photo of the pair of key Smiths that I’ve never seen before. Here are both, for review.
I’m a big fan of science fiction writing, and with humor it’s even better! Here’s a great one I found online, first a note from the author Terry Bisson, “I’m honored that this often shows up on the internet. Here’s the correct version, as published in Omni, 1990. Thanks for your interest in my work. If you enjoyed this little piece, please give a dollar to a homeless person.”
