Subject: Bind TUN to IPv4 Subnet
Date: Wed, 19 Jul 2006 17:26:49 +0200 [thread overview]
Message-ID: <44BE4F39.70405@pixel-house.net> (raw)
Hey Folks,
I need to bind a TUN device previously created by open("/dev/net/tun",
O_RW) to a subnet, let's say 10.254.0.0/16. The ultimate goal is to have
a tunnel endpoint for a IPv4 tunnel, where I can after writing the
packet which came over the tunnel to the TUN device use an arbitary
userland socket bound to one of the 2^16 IPs or just all of them with
with INADDR_ANY.
What is the (sequence?) of ioctl's to configure the TUN device into
`listening' on a whole subnet? If possible, I want to just specify a
base address and a prefix length.
Digging into the curent 2.6.x kernel sources didn't help me much (yes,
they are badly commented).
Thanks,
Georg Wicherski
