|
|
.SH DESCRIPTION
|
|
|
|
|
N2N is a peer-to-peer VPN system. Supernode is a node introduction registry,
|
|
|
|
|
broadcast conduit and packet relay node for the n2n system. On startup supernode
|
|
|
|
|
begins listening on the specified UDP port for node registrations, and other
|
|
|
|
|
packets to route. The supernode can service any number of communities and routes
|
|
|
|
|
packets only between members of the same community. The supernode does not hold
|
|
|
|
|
the community encryption key and so cannot snoop or inject packets into the
|
|
|
|
|
community.
|
|
|
|
|
.PP
|
|
|
|
|
Supernode can service a number of n2n communities concurrently. Traffic does not
|
|
|
|
|
cross between communities.
|
|
|
|
|
.PP
|
|
|
|
|
All logging goes to stdout.

|
|
|
|
normal traffic flow to resume.
