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.
