Dapper Distributed Dataflow Engine 0.91 (Default branch)

Dapper, or "Distributed and Parallel Program Execution Runtime", is a tool for taming the complexities of developing for large-scale cloud and grid computing, enabling the user to create distributed computations from the essentials: the code that will execute, along with a dataflow graph description. It supports rich execution semantics, carefree deployment, a robust control protocol, modification of the dataflow graph at runtime, and an intuitive user interface.

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.
