ZNC
ZNC is an advanced IRC bouncer that stays connected to the server, so an IRC client can disconnect/reconnect without losing the chat session.
Note
For this guide you should be familiar with the basic concepts of
License
All relevant legal information can be found here:
Prerequisites
To make the application accessible from the outside, open a port in the firewall:
[isabell@stardust ~]$ uberspace port add
Port 40132 will be open for TCP and UDP traffic in a few minutes.
[isabell@stardust ~]$
Installation
Create a new directory, download the latest version and enter the directory you just created:
[isabell@stardust ~]$ mkdir ~/znc
[isabell@stardust ~]$ curl https://znc.in/releases/znc-latest.tar.gz | tar -xzvC ~/znc --strip-components=1
[isabell@stardust ~]$ cd ~/znc
[isabell@stardust znc]$
Compile and install ZNC to your home directory:
[isabell@stardust znc]$ ./configure --prefix="$HOME/.local"
[...]
[isabell@stardust znc]$ make
[...]
[isabell@stardust znc]$ make install

Use your own certificate
ZNC ships with a self generated certificate which will cause a warning in all modern browsers. To prevent this, we have to use our own certificate. Enter the ~/.znc/configs directory and generate a dhparam.pem file:
[isabell@stardust ~]$ cd ~/.znc/configs
[isabell@stardust configs]$ openssl dhparam -out dhparam.pem 2048
[...]
[isabell@stardust configs]$
Warning
Replace isabell with your username!
Add the following lines to ~/.znc/configs/znc.conf above the line Version = 1.7.3 (your version number may differ):
SSLCertFile = /home/isabell/etc/certificates/isabell.uber.space.crt
SSLKeyFile = /home/isabell/etc/certificates/isabell.uber.space.key
SSLDHParamFile = /home/isabell/.znc/configs/dhparam.pem
Setup daemon
Create ~/etc/services.d/znc.ini with the following content:
[program:znc]
command=%(ENV_HOME)s/.local/bin/znc --foreground
autostart=yes
autorestart=yes
After creating the configuration, tell supervisord to refresh its configuration and start the service:
[isabell@stardust ~]$ supervisorctl reread
SERVICE: available
[isabell@stardust ~]$ supervisorctl update
SERVICE: added process group
[isabell@stardust ~]$ supervisorctl status
SERVICE RUNNING pid 26020, uptime 0:03:14
[isabell@stardust ~]$
If it’s not in state RUNNING, check your configuration.
Open webadmin
Warning
Replace isabell with your username and 40132 with your port!
If ZNC is running, you can find the web interface for further configuration here:
Connect your client
Add a new server in your local IRC client:
Hostname: <username>.uber.space
Port: your port
Username: ZNC nickname
Password: ZNC password
Encryption: yes
Updates
Note
Check https://wiki.znc.in/ZNC regularly to stay informed about the newest version.
To update an existing installation remove the ~/znc directory (rm -rf ~/znc) and repeat the Installation steps. Execute supervisorctl restart znc to start the new version.
