CTparental - Featured Parental Control Tool for Linux
CTparental is a parental control tool used to control how someone uses the computer, either for internet browsing or any other specific Computer usage. Design of CTparental was motivated by existing tools like iptables, dnsmasq, inguardian Privoxy which independently can do some parts but missing other pieces. So in essence, CTparental leverage all these tools to create a fully-fledged parental control solution with an intuitive and easy to use web interface powered by lighttpd. Now that you know what CTparental, we can go ahead and install it on our Operating system. We'll cover installation for Ubuntu 16.04 and Debian 9 since these are the latest release of both distributions as of this writing.Features of CTparental

Accessing CTparental Web Interface
Now that everything is set - We have installed the CTparental package successfully, It's time to access the web interface and do further configurations from there. The web URL will be configured automatically, with relevant iptables rules in place. No further configurations are required for the URL to be functional. To access the web interface for CTparental, use this link:https://admin.ct.local
The hostname admin.ct.local has an ip address which you can confirm from a ping on the local system:
$ ping -c 2 admin.ct.local PING admin.ct.local (127.0.0.11) 56(84) bytes of data. 64 bytes from admin.ct.local (127.0.0.11): icmp_seq=1 ttl=64 time=0.038 ms 64 bytes from admin.ct.local (127.0.0.11): icmp_seq=2 ttl=64 time=0.052 ms --- admin.ct.local ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1026ms rtt min/avg/max/mdev = 0.038/0.045/0.052/0.007 msThis ip is mapped to ip /etc/hosts file as below:
# cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 mypc ...... 127.0.0.11 admin.ct.local fc00::127:11 admin.ct.local 127.0.0.10 privet.ct.local fc00::127:10 privet.ct.localThis asks for authentication - use the username and the password provided earlier during the setup.
