VDE_TUNCTL(8) System Manager's Manual VDE_TUNCTL(8)
NAME
vde_tunctl — create and manage persistent TUN/TAP interfaces
SYNOPSIS
vde_tunctl [-f clone-dev] [-u owner] [-g group] [-n] [-t dev-name]
vde_tunctl [-f clone-dev] -d dev-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 an extension of tunctl.
vde_tunctl defines tap interfaces unless dev-name begins by "tun" or
the option -n appears in the command line.
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
To create or destroy a tun interface (instead of tap):
# vde_tunctl -n -u someuser
Set 'tun0' persistent and owned by uid 500
# vde_tunctl -d tun0
Set 'tun0' nonpersistent
