Network Simulator in Go

Minimal network simulator written in Go. Inspired by INetSim.

Features:

• Create DNS server on all addresses and respond to all queries with its own IP
• Create Web server (HTTP/HTTPs) responding to all requests based user configuration
• For HTTPs it generates on the fly server certificate (based on requested server name)

Installing CA certificate

Linux

Export the CA certificate somewhere with the "Save CA certificate" button. You can import the CA certificate directly in your browser settings, for example in Firefox go to Settings -> Certificates -> Authorities -> Import...

Windows

TBA
