Ethertap network tap (EXPERIMENTAL)
Universal TUN/TAP device driver.
CONFIG_TUN
TUN/TAP provides packet reception and transmission for user space programs.
It can be viewed as a simple Point-to-Point or Ethernet device, which
instead of receiving packets from a physical media, receives them from
user space program and instead of sending packets via physical media
writes them to the user space program.
When a program opens /dev/net/tun, driver creates and registers
corresponding net device tunX or tapX. After a program closed above
devices, driver will automatically delete tunXX or tapXX device and all
routes corresponding to it.
Please read Documentation/networking/tuntap.txt for more information.
This driver is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called tun.o. If you want to compile it as a
module, say M here and read Documentation/modules.txt.
If you don't know what to use this for, you don't need it.

1. Description
TUN/TAP provides packet reception and transmission for user space programs.
It can be viewed as a simple Point-to-Point or Ethernet device, which
instead of receiving packets from a physical media, receives them from
user space program and instead of sending packets via physical media
writes them to the user space program.
When a program opens /dev/net/tun, driver creates and registers corresponding
net device tunX or tapX. After a program closed above devices, driver will
automatically delete tunXX or tapXX device and all routes corresponding to it.
This package(http://vtun.sourceforge.net/tun) contains two simple example
programs how to use tun and tap devices. Both programs works like
bridge between two network interfaces.
br_select.c - bridge based on select system call.
br_sigio.c - bridge based on async io and SIGIO signal.
However the best example is VTun http://vtun.sourceforge.net :))
2. Installation
Run './configure' to configure the driver.
Run 'make install' to compile and install driver module and to create
/dev/net/tun device node.
3. Loading driver module
Linux
To load TUN/TAP driver module run:
modprobe tun
To configure automatic loading of the 'tun' module you have to add:
alias char-major-195 tun
to the /etc/conf.modules, and run:
modprobe -a
TUN/TAP driver will be automatically loaded when application access
/dev/net/tun.
If "Kernel module loader" - module auto-loading support is not enabled
in your kernel then you can add
modprobe tun
to one of the startup rc files.
4. Program interface
4.1 Network device allocation:
int tun_alloc(char *dev)
{
struct ifreq ifr;
int fd, err;
if( (fd = open("/dev/net/tun", O_RDWR)) < 0 )
return tun_alloc_old(dev);
memset(&ifr, 0, sizeof(ifr));
/* Flags: IFF_TUN - TUN device (no Ethernet headers)
* IFF_TAP - TAP device
*
* IFF_NO_PI - Do not provide packet information
*/
ifr.ifr_flags = IFF_TUN;
if( *dev )
strncpy(ifr.ifr_name, dev, IFNAMSIZ);
if( (err = ioctl(fd, TUNSETIFF, (void *) &ifr)) < 0 ){
close(fd);
return err;
}
strcpy(dev, ifr.ifr_name);
return fd;
}
4.2 Frame format:
If flag IFF_NO_PI is not set each frame format is:
Flags [2 bytes]
Proto [2 bytes]
Raw protocol(IP, IPv6, etc) frame.
Universal TUN/TAP device driver Frequently Asked Question.
1. What is the TUN ?
The TUN is Virtual Point-to-Point network device.
TUN driver was designed as low level kernel support for
IP tunneling. It provides to userland application
two interfaces:
- /dev/tunX - character device;
- tunX - virtual Point-to-Point interface.
Userland application can write IP frame to /dev/tunX
and kernel will receive this frame from tunX interface.
In the same time every frame that kernel writes to tunX
interface can be read by userland application from /dev/tunX
device.
2. What is the TAP ?
The TAP is a Virtual Ethernet network device.
TAP driver was designed as low level kernel support for
Ethernet tunneling. It provides to userland application
two interfaces:
- /dev/tapX - character device;
- tapX - virtual Ethernet interface.
Userland application can write Ethernet frame to /dev/tapX
and kernel will receive this frame from tapX interface.
In the same time every frame that kernel writes to tapX
interface can be read by userland application from /dev/tapX
device.
3. What platforms are supported by TUN/TAP driver ?
Currently driver has been written for 3 Unices:
Linux kernels 2.2.x, 2.4.x
FreeBSD 3.x, 4.x, 5.x
Solaris 2.6, 7.0, 8.0
4. What is TUN/TAP driver used for?
As mentioned above, main purpose of TUN/TAP driver is tunneling.
It used by VTun (http://vtun.netpedia.net).
5. How does Virtual network device actually work ?
Virtual network device can be viewed as a simple Point-to-Point or
Ethernet device, which instead of receiving packets from a physical
media, receives them from user space program and instead of sending
packets via physical media sends them to the user space program.
Let's say that you configured IPX on the tap0, then whenever
kernel sends any IPX packet to tap0, it is passed to the application
(VTun for example). Application encrypts, compresses and sends it to
the other side over TCP or UDP. Application on other side decompress
and decrypts them and write packet to the TAP device, kernel handles
the packet like it came from real physical device.
6. What is the difference between TUN driver and TAP driver?
TUN works with IP frames. TAP works with Ethernet frames.
7. What is the difference between BPF and TUN/TAP driver?
BFP is a advanced packet filter. It can be attached to existing
network interface. It does not provide virtual network interface.
TUN/TAP driver does provide virtual network interface and it is possible
to attach BPF to this interface.
8. Does TAP driver support kernel Ethernet bridging?
Yes. Linux and FreeBSD drivers support Ethernet bridging.
