To use the Firewall CLI package ‘system-config-firewall-tui’ a few extra dependencies need to be installed that by default are not resolved.
Install dependencies and start required service, then the firewall utility should start without error.
1 | yum install system-config-firewall-tui dbus dbus-python |
2 | service messagebus start |
3 | system-config-firewall-tui |
