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
