Implement -i parameter to allow specifying which interface to bind to #1

Closed RMerl closed 4 years ago

RMerl commented 5 years ago

By default wsdd2 binds to all available interfaces. In a router's case this means it would also bind to the WAN interface, which is a security risk. This allows to instruct wsdd2 to which specific interface to bind to.

That fix appear to be incomplete. While it at least reduces the number of sockets, connecting from an unprotected WAN still seems to succeed. I suppose the socket code will need to be amended to only bind to the interface's IP address, and not to 0.0.0.0.
