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.
