NAME
tunctl -- create and manage persistent TUN/TAP interfaces SYNOPSIS
tunctl [-f tun-clone-device] [-u owner] [-t device-name] tunctl [-f tun-clone-device] -d device-name DESCRIPTION
This manual page documents briefly the tunctl command. 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. 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. USAGE
To create an interface for use by a particular user, invoke tunctl without the -d option: # tunctl -u someuser Set 'tap0' persistent and owned by 'someuser' 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: # tunctl -d tap0 Set 'tap0' nonpersistent SEE ALSO
The UserModeLinux-HOWTO (link to URL http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO.html) AUTHOR
tunctl was written by Jeff Dike jdike@karaya.com This manual page was written by Matt Zimmerman mdz@debian.org for the Debian GNU/Linux system, based on examples from Jeff Dike. TUNCTL(8)
