virt manager cannot find suitable emulator for x86 64

Looks like I was missing qemu-kvm.

$ sudo apt-get install qemu-kvm qemu-system

Some work on a VyOS image with Let’s Encrypt certs

I put some packages together this weekend. It’s been a while since I’ve debuilt anything officially.

The plan is to build a binding to the libgnutls.so.30 API. The certtool CSR (REQ) generation interface does not allow me to create a CRL with “not critical” attributes set on purposes. Maybe if I do it a bit closer to the metal it will be easier…

OMG Maven 3.0.4 on stretch

“Why?”, you might ask, would one want to run something other than the most recent version of Maven on the very newest and fangledest breed of the linux distribution we have all loved for so long.

“Because!”, I might answer, I’m trying to get the nexus-apt-plugin working on nexus.fd.io, and the version of nexus we’re running there explained to me in quite uncertain terms that it would talk to no other version of maven than 3.0.4 or something else that is not packaged for debian.

So I grabbed the source for version 3.0.4 from wheezy and patched it up to work with stretch:

$ cd /usr/src/deb
$ dget http.debian.net/debian/pool/main/m/maven/maven_3.0.4-3+deb7u1.dsc
$ cd maven-3.0.4
$ perl -i -pe 's/(libmodello-maven-plugin)1.4(-java)/$1$2/' debian/control
$ quilt pop -a
$ quild push 1
$ perl -i -pe 's/-1.4.x\.jar/.jar/' build.xml
$ perl -i -pe 's/google-collections/guava/' build.xml
$ perl -i -pe 's/\s+$//' build.xml
$ quilt refresh
$ quilt pop
$ quilt push -a
$ debuild -uc -us
$ sudo apt-get remove maven libmaven3-core-java
$ sudo dpkg -i ../maven_3.0.4-3+deb7u1_all.deb

And now I can build the silly nexus-apt-plugin…

$ mkdir -p /usr/src/git/github
$ git clone git@github.com:LLC-Technologies-Collier/nexus-apt-plugin.git /usr/src/git/github/nexus-apt-plugin
$ cd /usr/src/git/github/nexus-apt-plugin
$ mvn compile && mvn -q test

LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS

Hello dear readers and attendees,

This is the post that I will be/ will have been referencing during my presentation to the Seattle Central Community College’s Byte club on Thursday, December 10th at 1500-1630.

I will begin with a bit of an autobio and find out what kind of students we have in attendance. Please feel free to comment if you’d like to keep in touch before or after the presentation. I will discuss some of the bits and pieces of some industry standard platforms which I’ve developed, deployed, maintained, managed, co-operated, administered and replaced. We can discuss some of the patterns that work well in the industry, and some that are a bit harder to tame.

Once we have touched most of the areas of specialization represented at the meeting, I will dive in to an AngularJS demo I am developing in github here:

https://github.com/LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS/tree/master

To follow along with the presentation, please run these commands or something similar. My development environment is Debian stable. So yes, this means that we’re not doing a demo of the state of the art. But it also means that the infrastructure has been exercised under load and in production.

Install Debian package dependencies

First, install the debian packages of nodejs and npm, the node package manager:

cjac@debian0:~$ sudo apt-get install nodejs nodejs-dev nodejs-legacy npm

Check out the git repository

After this, check out the repository from github and create a branch for your work:

cjac@debian0:~$ mkdir -p /usr/src/git/github/LLC-Technologies-Collier
cjac@debian0:~$ cd /usr/src/git/github/LLC-Technologies-Collier
cjac@debian0:/usr/src/git/github/LLC-Technologies-Collier$ git clone git@github.com:LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS.git
...
cjac@debian0:/usr/src/git/github/LLC-Technologies-Collier$ cd Demo-SCCC-Byte-AngularJS
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ git checkout -b $USER

Upgrade to latest npm, install deps

Once we have the git repository checked out, we’ll grab the latest version of npm and the rest of the node modules

cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ export PATH="$PWD/node_modules/.bin:$PATH"
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ npm install --save-exact npm@"2.1.0"
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ npm install --save-exact `cat pkgackage-list.txt`

This post and the associated git repository will be updated between now and the presentation on Thursday. Please chime in and feel free to get involved!

Regarding fdupes

Dear readers,

There is a very useful tool for finding and merging shared permanent storage, and its name is fdupes. There was a terrible occurrence in the software after version 1.51, however. They removed the -L argument because too many people were complaining about lost data. It sounds like user error to me, and so I continue to use this one. I have to build from source, since the newer versions do not have the -L option.

https://github.com/tobiasschulz/fdupes

And so there you are. I recommend using it, even though this most useful feature has been deprecated and removed from the software. Perhaps there should be a fdupes-danger package in Debian?

I think I just accidentally the whole Seattle EDM scene

It was unintentional, I promise.

PS, what are you doing the night before Samhain this year? Feel like giving me and my bike a ride to Bellingham?

Some statistics from the router at the cabin

sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface.

eth9 is the local gigabit transceiver. Attached directly to a SIP phone which bridges to a gigabit switch, on which the Ubiquity equipment participates.

lo is the local loopback interface, of course. Good old 127/8

usb1 is the 100Mbit USB NIC to which the WRT54G with ssid ‘colliertech.org’ is attached. The vast majority of the traffic originates on this interface.
