VDE_PLUG2TAP(1)        DragonFly General Commands Manual       VDE_PLUG2TAP(1)


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
