ZNC in a DigitalOcean droplet
It is nice to have an IRC connection that is always available and that doesn’t have your home IP address exposed. With the ZNC setup you can then use your local IRC client (BitchX, irssi, HexChat etc) to connect to the ZNC and you will be able to see all the networks and channels it is connected to. This tutorial will explain how to setup ZNC on a $5/month DigitalOcean droplet (ref link) with Ubuntu 16.04.1. Of course this setup should work on any hosting and setup – DigitalOcean is just given as an example here.
Create a Droplet
1. Press on the Create a Droplet button once you are logged in your DO account
- Select the OS image (Ubuntu 16.04.X), the Droplet size/price ($5/mo), data center region, add extra features, ssh key if you want that extra security and then press on Create Droplet
2. Login to your Droplet (box) and make sure everything is up to date
sudo apt-get update sudo apt-get upgrade
Installation and Build of ZNC
1. Grab few essentials that are needed to compile the ZNC from source
sudo apt-get install build-essential libssl-dev libperl-dev pkg-config
2. Grab the latest ZNC source tar ball
cd /usr/local/src; sudo wget http://znc.in/releases/znc-latest.tar.gz
3. Extract the package and enter the directory
sudo tar -xzvf znc-latest.tar.gz; cd znc*
4. Configure the source system wide (you can use ./configure –prefix=$HOME/znc if you don’t want system wide)
5. Then, compile ZNC (might take few minutes)
sudo make; sudo make install
Configuration of ZNC
1. Create a new user on which we will run ZNC
2. Switch to the new user
su znc-admin; cd ~
3. Start ZNC and its configuration
4. Below is a sample configuration (ZNC version 1.6.4) – I highlighted in red all the config that I entered manually, the rest is the default values (what is given in the brackets [ ])

That is it – ZNC is now up and running!
Connect to ZNC with your local IRC Client
Now find the IP address from your Droplet and setup your IRC client to connect to it.
Example with HexChat:
After connecting to the ZNC all the networks and channels you have added will appear.
