.SH "DESCRIPTION" 
.PP 
\fBvde_tunctl\fR 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. 
.PP
vde_tunctl is a simple copy of \fBtunctl\fR done for practical purposes.
.SH "USAGE" 
.PP 
To create an interface for use by a particular user, invoke 
tunctl without the \-d option: 
.PP 
.nf 
# \fBvde_tunctl \-u someuser\fP  
Set 'tap0' persistent and owned by uid 500 
 
.fi 
.PP 
Then, configure the interface as normal: 
.PP 
.nf 
# \fBifconfig tap0 192.168.0.254 up\fP  
# \fBroute add \-host 192.168.0.253 dev tap0\fP  
# \fBbash \-c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'\fP  
# \fBarp \-Ds 192.168.0.253 eth0 pub\fP        
.fi 
.PP 
To delete the interface, use the \-d option: 
.PP 
.nf 
# \fBvde_tunctl \-d tap0\fP  
Set 'tap0' nonpersistent 
 
.fi
