vde_tunctl — create and manage persistent TUN/TAP interfaces

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
