VDE_TUNCTL(8)          DragonFly 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
