Pidgin ZNC Helper: Quick Setup Guide for BeginnersIf you use Pidgin for instant messaging and want to keep your IRC sessions persistent, ZNC is a powerful IRC bouncer that stores messages and maintains connections for you. The Pidgin ZNC Helper plugin simplifies connecting Pidgin to a ZNC bouncer, handling SASL, port settings, and per-network user configurations. This guide walks you through installing ZNC and the Pidgin ZNC Helper plugin, configuring both ends, and troubleshooting common problems — aimed at beginners who want a reliable, always-on IRC experience.

What you’ll need

  • A machine or VPS where you can install and run ZNC (Linux is most common; Windows/macOS also possible).
  • Pidgin installed on your desktop (Windows, macOS via third-party builds, or Linux package).
  • Basic familiarity with terminal commands and editing text files (for ZNC setup).
  • The Pidgin ZNC Helper plugin installed in Pidgin.

Quick overview: how it works

ZNC runs on a server and acts as a middleman between IRC networks and your Pidgin client. Pidgin connects to ZNC (usually via a special user:username@zncserver:port or username/network), and ZNC keeps the IRC connections live even when your client disconnects. The Pidgin ZNC Helper plugin automates creation of accounts and settings for networks/channels in Pidgin so you don’t have to manually map each IRC network to ZNC connection strings.

Part 1 — Install and configure ZNC

1. Install ZNC

  • On Debian/Ubuntu: 
    
sudo apt update sudo apt install znc znc-dev znc-perl znc-python
  • On CentOS/RHEL (with EPEL): 
    
sudo yum install epel-release sudo yum install znc
  • On macOS (Homebrew): 
    
brew install znc
  • On Windows: use the official Windows installer from the ZNC website.

2. Run initial ZNC setup

Start the interactive setup:

znc --makeconf

During setup you’ll choose:

  • A listener port (commonly 6697 for SSL or 6667 for plain).
  • Whether to enable SSL (recommended).
  • Admin username and password.
  • Data directory (default is fine).
    Remember the admin credentials — you’ll use them for web admin and creating user accounts.

3. Configure an IRC user for your Pidgin client

You can create additional ZNC users besides admin:

  • Using the web interface (if enabled): access https://your-server:port/ and log in with admin credentials, then add users.
  • Or from the command line: 
    
znc --user=admin --makeconf

    Or use cncfg/zpasswd tools depending on your distro. A typical ZNC username format for clients is:

  • username/network or username/network/#channel Set the user’s password; if you plan to use SASL, note the username and password exactly.

4. Enable and configure modules

Popular modules:

  • playback — replay backlog to clients when they connect.
  • chanfilter — filter messages.
  • webadmin — web-based admin interface.
    Load modules via webadmin or: 

    
/msg *status loadmod playback

    from an IRC client connected through ZNC.

5. Open ports and enable SSL

  • Make sure the chosen listener port is open in your firewall.
  • If using SSL, point ZNC at your certificate and key in the ZNC settings or during makeconf. Consider using LetsEncrypt for free certificates.

Part 2 — Install Pidgin ZNC Helper plugin

1. Install Pidgin (if you haven’t)

  • Debian/Ubuntu: 
    
sudo apt install pidgin
  • macOS/Windows: download installers from Pidgin’s site or use package managers.

2. Get the Pidgin ZNC Helper plugin

  • Many distributions include a package named pidgin-znc (or pidgin-zynchelper). On Debian/Ubuntu: 
    
sudo apt install pidgin-zhc pidgin-znc

    (Package names vary; check your distro.)

  • If no package is available, download the plugin source from its repository (GitHub/GitLab) and build it: 
    
git clone https://github.com/<repo>/pidgin-znc-helper.git cd pidgin-znc-helper make sudo make install

    Follow the plugin’s README for build dependencies (libpurple dev headers, make, gcc).

3. Enable the plugin in Pidgin

  • Open Pidgin → Tools → Plugins → find “ZNC Helper” (or similar) → check to enable.
  • Click “Configure Plugin” to access plugin settings.

Part 3 — Configure Pidgin to use ZNC with the plugin

1. Add a new account

  • In Pidgin: Accounts → Manage Accounts → Add.
  • Protocol: IRC.
  • For “Username” use the ZNC username. Depending on your ZNC configuration and plugin behavior, use either:
    • username/network (recommended when using a single Pidgin IRC account to manage multiple networks via ZNC), or
    • username
  • For “Server”, put your ZNC host (e.g., znc.example.com).
  • For “Password”, use your ZNC password (the ZNC user’s password). If using SASL, many setups require the plugin to enable SASL and use the ZNC password here.

2. Port and SSL

  • Set port to the ZNC listener port (e.g., 6697 for TLS).
  • Check “Use SSL” if ZNC listener uses TLS.
  • If Pidgin complains about certificates, either import the CA that issued your ZNC certificate or accept the certificate.

3. Configure ZNC Helper plugin options

  • Open the plugin configuration: select networks, choose whether the plugin automatically creates accounts for networks it discovers, and set channel auto-join behavior.
  • Map Pidgin networks to ZNC networks if needed — many versions will automatically create sub-accounts for each IRC network using the username/network format.

4. Using SASL

  • If your ZNC requires SASL (recommended for secure authentication over plain ports), enable SASL in the Pidgin IRC account options (there’s usually a checkbox “Authenticate using SASL” or similar). Use your ZNC username and password for SASL credentials.

Part 4 — Typical workflows

  • Multi-network single Pidgin account: use username/network in one IRC account; plugin lets you manage channels per network while ZNC keeps them connected.
  • Playback on connect: configure the playback module in ZNC and set your plugin to request playback so you receive messages missed while offline.
  • Channel auto-join: store channel lists in ZNC or let Pidgin auto-join via stored server settings; plugin helps sync these.

Troubleshooting

  • Cannot connect:

    • Verify server/port/SSL settings and that ZNC is running.
    • Check firewall rules on the server.
    • Test with a simple IRC client (irssi/weechat) to narrow down Pidgin vs ZNC issues.

  • SASL failures:

    • Make sure SASL is enabled in ZNC and Pidgin, and that username/password are correct.
    • Some setups require username in the form username/network for SASL; try both.

  • Certificate warnings:

    • Use proper CA-signed certs (Let’s Encrypt) or import the self-signed cert into your system trust store.

  • Playback not working:

    • Ensure the playback module is loaded in ZNC and that the user has permissions and buffers enabled. Configure the plugin to request backlog.

Security & best practices

  • Use SSL/TLS for the ZNC listener.
  • Use strong passwords and consider SSH keys for server access.
  • Keep ZNC and Pidgin updated.
  • Limit admin web interface access (bind to localhost + SSH tunnel, or use firewall rules).
  • Regularly back up ZNC’s data directory.

Example minimal configuration (cheat-sheet)

  • ZNC run with TLS on port 6697, user alice, password s3cr3t. Playback module loaded.
  • Pidgin IRC account:
    • Username: alice/Libera
    • Server: znc.example.com
    • Password: s3cr3t
    • Port: 6697
    • Use SSL: checked
    • SASL: enabled

Connect — Pidgin should show networks and channels managed by ZNC and request any backlog if playback is enabled.

If you want, I can:

  • Provide exact commands for your server OS, or
  • Walk through configuring the plugin step-by-step in your Pidgin instance, or
  • Write a short beginner-friendly script to auto-install ZNC with a basic configuration.
