[Openswan Users] klips Warning: unknown symbol

[Christopher Malott]

I am also running into this Identical problem with FC4.

I've disabled NET_KEY support in the kernel, patched with the latest dr8 
release against a 2.6.12 kernel. I also tried to #define NET_26 in 
pfkey_v2.c to no avail.

I know there have been a few individuals who have seen success when 
compiling KLIPS support into a 2.6 kernel. Any thoughts or ideas on what 
we might need to do?

Best Regards,
Christopher Malott
