This project has ended. I've taken down the website and ceased development of this application. I'm leaving the code up on github in the hope that it's useful for someone. Enjoy looking at this little piece of history.

This is the code that powers callsigns.ca. It started with the simple desire for a simple mobile friendly way of searching the Canadian Callsign Database and ended with me developing my own website.

• mobile friendly design that also works on the desktop and in the terminal
• bilingual user interface (English and French)
• no advertisements nor any form of monetization (strictly non-commercial)
• no login required to access any part of the site
• no social media buttons to distract you
• no cookies beyond an ephemeral session cookie for language preference
• free and open source code

• systemd
• iptables
• nginx
• openssl
• mysql
• wget
• unzip
• node.js
• npm
• letsencrypt

Grab the source code:

mkdir -p /var/node && cd /var/node
git clone git://github.com/tcort/callsigns.git && cd callsigns

Install the dependencies:

Configure iptables:

iptables-restore < ./etc/iptables/rules.v4
ip6tables-restore < ./etc/iptables/rules.v6
apt-get install iptables-persistent

Configure:

Populate the database:

/var/node/callsigns/db/refresh.sh

Add a cron job to refresh the database:

crontab -e
15 1   *   *   *   /var/node/callsigns/db/refresh.sh >/dev/null 2>&1

Configure rsyslog:

sudo -e /etc/rsyslog.conf
local5.*                        /var/log/callsigns.log
sudo service rsyslog restart
logger -p local5.info "Test"

Get SSL Certificates:

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto --agree-dev-preview --server \
    https://acme-v01.api.letsencrypt.org/directory certonly

Generate DHE Parameters:

openssl dhparam -out /etc/ssl/certs/dhparam.pem 4096

Configure nginx:

cp /var/node/callsigns/etc/nginx/sites-available/callsigns.ca /etc/nginx/sites-available/callsigns.ca
$EDITOR /etc/nginx/sites-available/callsigns.ca
systemctl restart nginx

Configure the service:

cp /var/node/callsigns/etc/systemd/system/callsigns.service /etc/systemd/system/callsigns.service
