Imitating even a small part of it can be time consuming and hard to manage. Lots of services, like DNS servers, certificate authorities, and email providers, need to work together properly like they do on the internet.
FakerNet is built to make it easy configure and deploy new internet-like services, keeping you away from tedious configurations. FakerNet integrates modules together to get services working together fast.
FakerNet uses lightweight LXC and Docker containers instead of more resource intensive virtual machines. This means we can have a large "internet" full of different services without all the overhead that comes with virtual machines.
FakerNet is open-source and easy to extend with your own modules. This makes it easy to add any service you need in your "internet." Modules can be easily made to interact and integrate with each other, so you don't have to rewrite everything.
