SYNOPSISvde_plug [ -p portnum ] [ -g group ] [ -m octal-mode ] [ socketdir ]
DESCRIPTIONA vde_plug is a plug to be connected into a VDE switch. All the data that is catched by the plug is written in its stdout and everything from stdin is injected in the switch.
This tool has been designed to be used together with dpipe (1) to interconnect a second vde_plug to another switch, working as a virtual ethernet crossed cable between the two switches.
dpipe vde_plug = vde_plug /tmp/vde2.ctl
dpipe vde_plug = ssh remote.machine.org vde_plug
vde_plug can also be established as a login shell for users. The following command works as in the previous example
dpipe vde_plug = ssh [email protected] vde_plug
- -p 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 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 octal-mode
- octal chmod like permissions for the comm sockets
- (This option can be also set as: -sock socketdir ) specify the directory which contains the UNIX socket to be used by local programs for joining the VDE. The default value is "/tmp/vde.ctl", which corresponds to the socket "/tmp/vde.ctl/ctl" (or /var/run/vde.ctl when the vde_switch runs as a shared daemon). It is possible for users to redefine their default switch as ".vde-2/stdsock" in their home directory. If exist, this directory (or symbolic link to the actual directory) is used as the default value for the user.
