NAME

       curvetun - lightweight curve25519-based multiuser IP tunnel

SYNOPSIS

       curvetun [-d|--dev <tun>][-x|--export][-C|--dumpc][-S|--dumps] [-k|--keygen][-c|--client [<alias>]][-s|--server][-N|--no-logging]
       [-p|--port <num>][-t|--stun <server>][-4|--ipv4][-6|--ipv6] [-v|--version][-h|--help]

DESCRIPTION

       curvetun embeds a client and a server to build and manage multiuser IP tunnels using Elliptic Curve Cryptography (ECC)

EXAMPLES

       curvetun --keygen
           Generate public/private keypair. This needs to be done before to get things started.

       curvetun --export
           Export public data to remote servers

       curvetun --server -4 -u -N --port 6666 --stun stunserver.org
           Start a UDP IPv4 curvetun server on port 6666.  Use stunserver.org as STUN server.

       curvetun --client=ethz
           Start curvetun client using the profile called 'ethz'
