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.
