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.
