vde_tunctl — create and manage persistent TUN/TAP interfaces
vde_tunctl [-f tun-clone-device] [-u owner] [-t device-name]
vde_tunctl [-f tun-clone-device] -d device-name
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.
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
