OpenNDS is a high performance, small footprint Captive Portal, offering by default a simple splash page restricted Internet connection yet incorporates an API that allows the creation of sophisticated authentication applications.
After installing the snap you can adjust the configuration file in /var/snap/opennds/common/opennds/opennds.conf following the documentation at https://openndsdocs.readthedocs.io/en/stable/
Then you need to allow the snap access to the firewall, network configuration, mount information and some system resources with the commands
sudo snap connect opennds:firewall-control
sudo snap connect opennds:hardware-observe
sudo snap connect opennds:mount-observe
sudo snap connect opennds:network-observe
sudo snap connect opennds:system-observe
After connecting these snap interfaces, the opennds daemon will start
automatically. To interact with the daemon the snap package ships
the opennds.ndsctl command

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install opennds, simply use the following command:
sudo snap install opennds --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
