VDE_TUNCTL(8)						      System Manager's Manual						     VDE_TUNCTL(8)

NAME

       vde_tunctl -- create and manage persistent TUN/TAP interfaces

SYNOPSIS

       vde_tunctl [-f tun-clone-device]  [-u owner]  [-t device-name]

       vde_tunctl [-f tun-clone-device] -d device-name

DESCRIPTION

       vde_tunctl  allows the host sysadmin to preconfigure a TUN/TAP device for use by a particular user.  That user may open and use the device,
       but may not change any aspects of the host side of the interface.

       vde_tunctl is a simple copy of tunctl done for practical purposes.

USAGE

       To create an interface for use by a particular user, invoke tunctl without the -d option:

       # vde_tunctl -u someuser
       Set 'tap0' persistent and owned by uid 500

       Then, configure the interface as normal:

       # ifconfig tap0 192.168.0.254 up
       # route add -host 192.168.0.253 dev tap0
       # bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
       # arp -Ds 192.168.0.253 eth0 pub

       To delete the interface, use the -d option:

       # vde_tunctl -d tap0
       Set 'tap0' nonpersistent
