This is a mirror of the DuckDNS server code. This source was provided on 20180513 by Steven of duckdns.org and is availble from http://bit.ly/DuckSource_GDrive.

DuckDNS is an excellent service, and I am very happy with what they provide! I was extremely excited when they decided to release the entire server stack code as GPL3!

This is a servlet project In Eclipse you can run it on Tomcat for easy development (see below) Updates are cached in each server to reduce DB lookups. Sessions are held in DynamoDB Updates cause a push to each DNS server with an event that flushes the cache in the DNS Events are passed to Google ANALYTICS for real time monitoring

In product this runs in jetty 9 When packaged, all dependent libs are not included, to make it lighter to publish. All jars are placed in jetty_base/libs/ext All Config is placed in jetty_base/resources

To create the duckdns.war Add an ANT view into Eclipse (Window | Show View | Other - ANT) Drag the build.xml into the ant window Double click on the "Duck Website" ant file The war will be built at : dist/duckdns.war This task also copies your Secrets from the secrets project - see the ../samplesecrets project ../secrets/aws/AwsCredentials.properties ../secrets/jetty/secrets.properties

You will need to choose a domain to do your OAUTH on, each provider needs setting up. Put a host file in your local machine to test if it works, the providers will be redirecting your browser to this domain

You will need the correct OAUTH config in secrets.properties You will need a SALT config in secrets.properties You will need a GOOGLE ANALYTICS config in secrets.properties You will need the INTERNAL and EXTERNAL IPS setting config in secrets.properties (can be 127.0.0.1 for now)

extract tomcat to a location e.g. /apps localsetup/resources/apache-tomcat-7.0.57.tar.gz

Then add a new tomcat 7 server - use /apps as the file location - also select JDK 8 Set the domain as localdev.duckdns.org (I have this set to 127.0.0.1)

Now right click on the duckdns project and choose RUN : RUN ON SERVER Select the new tomcat 7 server localhost:8080 should be working

We run Jetty using an JETTY_BASE Copy the folder : conf/jetty_config -> jetty_base

In the base are all the files we add to jetty to make it work - copy these in WebContent/WEB-INF/lib/.jar -> /jetty_base/lib/ext/ resources/ -> /jetty_base/resources/ secrets/* -> /jetty_base/resources/

export PATH=/apps/java/jdk_current/bin:${PATH};export JAVA_HOME=/apps/java/jdk_current;export JETTY_USER=jetty;export JETTY_HOME=/apps/jetty/jetty_current;export JAVA_OPTIONS="-d64 -server -Xms200m -Xmx200m";export JETTY_PORT=8080;export JETTY_RUN=${JETTY_HOME}/run;export LANG=en_GB.ISO8859-1;export JETTY_BASE=/apps/jetty/jetty_config; ${JETTY_HOME}/bin/jetty.sh run

Scripts for this are in scripts/*

To release we copy the WAR to /var/tmp/duckdns.war Then we execute scripts/do_release.sh

Nginx is a lightweight webserver that provides a wrapper to jetty Jetty server all non dyanmic requests Requests pass through nginx to jetty when needed There is a sample Nginx config at : conf/nginx/default
