.It Cm deletetunnel
Removes the source and dsetination tunnel addresses, configured onto a tunnel interface.
This is used to specify an Internet host who is willing to receive ip packets encapsulating NS packets bound for a remote network.

System : OpenBSD 3.0 Architecture: OpenBSD.i386 Machine : i386 >Description: OpenBSD does not support network pseudo device cloning (runtime allocating of gif(4)-devices and such). >How-To-Repeat: - >Fix: Apply the patch below, recompile ifconfig and recompile (and install) your kernel. "ifconfig gifX create" (with X being a number) will from then on create a new gif(4)-device, and "ifconfig gifX destroy" will remove it. Note: This is based on PR 2165; the patch attached to that PR was incomplete though and did therefore not work. --- usr/include/sys/sockio.h.orig Sat Aug 10 02:48:15 2002 +++ usr/include/sys/sockio.h Sat Aug 10 02:48:22 2002
