NAME

       vde_plug2tap - Virtual Distributed Ethernet plug-to-tap

SYNOPSIS

       vde_plug2tap [OPTION]... tap_name

DESCRIPTION

       vde_plug2tap is a plug to be connected into a VDE switch.  All the data that is catched by
       the plug is sent to the tap interface tap_name  and  everything  from  that  interface  is
       injected in the switch.
       Example:
         vde_plug2tap tap4
       connects the default switch (/var/run/vde.ctl) to the tap4 interface.

OPTIONS

       -p, --port=portnum
              It  is possible to decide which port of the switch to use.  When this option is not
              specified the switch assigns the first available  unused  port  (if  any).   It  is
              possible  to  connect  several cables in the same switch port: in this way all this
              cables work concurrently.  It means that packet can result as duplicate but no  ARP
              table  loops  are  generated.   Is  useful  when  vde is used for mobility. Several
              physical interfaces can be used at a time during handoffs  to  prevent  hichups  in
              connectivity.

       -g, --group=group
              group ownership of the communication socket. For security when more want to share a
              switch it is better to use a unix group to own the comm sockets so that the network
              traffic cannot be sniffed.

       -m, --mod=octal-mode
              octal chmod like permissions for the comm sockets

       -s, --sock=socket
              specify  the  UNIX  socket  to  be used by local programs for joining the VDE.  The
              default value is "/var/run/vde.ctl".  When '-' is used in place of the  VDE  switch
              directory, vde_plug2tap works as a plug (see vde_plug(1)).  The command:
                dpipe vde_plug = ssh remote.machine.org vde_plug2tap -s - tapx
              connects the default local switch to a remote tapx interface.

       -d, --daemon
              start vde_plug2tap as a background process

       -P, --pidfile=pidfile
              put  the  process ID of vde_plug2tap in pidfile. Can be used with --daemon to store
              the PID for future killing.

       -h, --help
              show a brief help
