Hello Questions List,
(please cc, as I may not be on this list, (Too many daily messages))
I have previously setup a gif interface on a box called GM
using pseudo-device gif. I have tried several things to get the
gif interface back up and working. I will list them all in this
email. On an other note, the kernel source files used to be
located in the default /usr/src/sys/ have been moved to
/a/usr/src/sys/ (RAID5 on 3ware IDE RAID controller). If anyone
is interested in the details of the move I can paste them in if
people are intersted. And for the conveiniance of the person that
has physical access to the box, I symlinked /a/usr/src/sys to
/usr/src/sys .
The kernel was rebuilt the other day to add in support for
IPSEC and IPSEC_ESP to encrypt the connections. Since rebuilding
gif device no longer works. I have tried removing the IPSEC stuff
and rebuilding and go figure the gif device still doesnt work. So
I broke it, tried removing my changes, and its still broken.
I double-checked and "pseudo-device gif" is still in the kernel
config file.
I want to make it clear to everyone that I did have this working
in the past. I also dont have physical access to the box, so an
upgrade is not possible. (Plus, why upgrade something that has
worked in the past.)
And now for the problem:
gif0 does not show up in ifconfig, so I have tried creating the
device with methods that work on three other FreeBSD boxes
(4.8-stable from July 29th, 2003, and two 4.7-release boxes)
GM# ifconfig gif0 create
ifconfig: interface gif0 does not exist
Greenmantis# gifconfig gif0 local.public.ip.address remote.public.ip.address
gifconfig: interface gif0 does not exist
Greenmantis# ifconfig gif0 inet 10.1.1.2 192.168.0.2
ifconfig: interface gif0 does not exist
Where as on all of my other boxes, I dont get "gifconfig:
interface gif0 does not exist". It just silently creates the
device and returns me to the prompt.
I am really currious about why it worked before, but doesnt work now.
And to have other people double-check the kernel source file on
the busted machine, I will paste it here. Some confidential info has
been changed for privacy)
