VDE_PLUG2TAP(1) 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 concur-
rently. It means that packet can result as duplicate but no ARP table loops are generated. Is useful when vde is used for mobil-
ity. 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
