vde_over_ns - Steganographic cable over NS protocol for Virtual Distributed Ethernet

<H2>DESCRIPTION</H2>
A
<B>vde_over_ns</B>
allows to connect two remote vde_switches through steganographic NS query/response datagrams.
e.g.:
<P>
<B>dpipe vde_plug /tmp/s1 = vde_over_ns tun.mydomain.vde </B>
<P>
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.
<P>
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.
<P>
The same vde_over_dns server can be created using:
<P>
<B>vde_over_ns -s /tmp/s1 tun.mydomain.vde</B>
<P>
The syntax is almost identical for the client mode, except that
to have a vde_over_ns client connect to that server, the <B> -c </B><I>server</I>
option must be specified.
<P>
<A NAME="lbAE"> </A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT><B>-s </B><I>vdeplug</I>
<DD>
If specified, the vde_over_ns will connect to the local vde socket <I>vdeplug</I>
instead pf stdin/stdout, using the libvdeplug library.
<DT><B>-D </B>
<DD>
Detach console and send the process to background.
<DT><B>-b </B><I>ip.to.bind</I>
<DD>
The NS server will bind only to the specified ip, instead of any ip.
Only valid in server mode (without -c)
<DT><B>-c </B><I>server_addr</I>
<DD>
If specified, client mode is enabled. Vde_over_ns will try to send NS requests to <I>server_addr</I>. If not specified, server mode is enabled by default.
