How to create a captive portal for access to the network by check in in social networks?

Question

WiFi

Greetings!
the task was to create a captive portal for accessing the Internet, but for authorization it is necessary not to enter a password or even log in via oauth, but to check in on a social network (similar to Facebook Wi-Fi https://www.facebook.com/business /facebook-wifi ) + facebook wifi itself does not meet the requirements, as it should work when accessed via an ethernet connection.
Ideally, a purely software solution is needed with the ability to install a gateway on linux (centos 5.7 is a provider on the one hand, and a local network divided into subnets (vlans) on the other), but commercial solutions that require additional equipment will also suit ....
Thank you in advance for adviсe!
