NAME

vde_over_ns - Steganographic cable over NS protocol for Virtual Distributed Ethernet

SYNOPSIS

vde_over_ns [-D] [-c server_address] [-s vde_plug] [-i ip.to.bi.nd] domain.name

DESCRIPTION

A vde_over_ns allows to connect two remote vde_switches through steganographic NS query/response datagrams. e.g.:

dpipe vde_plug /tmp/s1 = vde_over_ns tun.mydomain.vde

binds to udp port 53 and listen for incoming steganographic NS queries (server mode). All the traffic to/from stdout/stdin is redirected to the client via ns responses.

creates a wire between two vde_switches (with sockets /tmp/s1 and /tmp/s2 respectively). This cable looses 10% of the packets in each direction.

The same vde_over_dns server can be created using:

vde_over_ns -s /tmp/s1 tun.mydomain.vde

The syntax is almost identical for the client mode, except that to have a vde_over_ns client connect to that server, the -c server option must be specified.

OPTIONS

-s vdeplug: If specified, the vde_over_ns will connect to the local vde socket vdeplug instead pf stdin/stdout, using the libvdeplug library.
-D: Detach console and send the process to background.
-b ip.to.bind: The NS server will bind only to the specified ip, instead of any ip. Only valid in server mode (without -c)
-c server_addr: If specified, client mode is enabled. Vde_over_ns will try to send NS requests to server_addr. If not specified, server mode is enabled by default.
