.SH NAME
tunctl \- create and manage persistent TUN/TAP interfaces
.SH SYNOPSIS

\fBtunctl\fR [ \fB-f \fItun-clone-device\fB\fR ] [ \fB-u \fIowner\fB\fR ] [ \fB-t \fIdevice-name\fB\fR ]


\fBtunctl\fR [ \fB-f \fItun-clone-device\fB\fR ] \fB-d \fIdevice-name\fB\fR

.SH "DESCRIPTION"
.PP
This manual page documents briefly the
\fBtunctl\fR command.
.PP
This manual page was written for the Debian GNU/Linux distribution
because the original program does not have a manual page.
Instead, it has documentation in HTML format; see below.
.PP
\fBtunctl\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.
.SH "USAGE"
.PP
To create an interface for use by a particular user, invoke
tunctl without the -d option:
.PP

.nf
        # \fBtunctl -u someuser\fR

        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\fR

        # \fBroute add -host 192.168.0.253 dev tap0\fR

        # \fBbash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'\fR

        # \fBarp -Ds 192.168.0.253 eth0 pub\fR
      
.fi
.PP
To delete the interface, use the -d option:
.PP

.nf
        # \fBtunctl -d tap0\fR

        Set 'tap0' nonpersistent
      
.fi
