Thanks Sam, for your reply,
First, let me say, I agree, the problem is likely with my netfilter
configuration.
I have these two symbols also unresolved in my bridge.o module. However,
it seems that I do have the ksyms (nf_hooks, and nf_hook_slow) in my kernel.
Hopefully, though, someone else has been down this path before me and
can steer
me to a solution. Please take a look at the info I am providing below
and tell me
the error of my ways.
bash-2.05# cat /proc/ksyms | grep nf_hook
c02015c8 nf_hook_slow_R__ver_nf_hook_slow
c02ecc80 nf_hooks_R__ver_nf_hooks
bash-2.05# depmod -ae
depmod: *** Unresolved symbols in
/lib/modules/2.4.18/kernel/net/bridge/bridge.o
depmod: nf_hooks
depmod: nf_hook_slow
depmod: *** Unresolved symbols in
/lib/modules/2.4.18/kernel/net/ipsec/ipsec.o
depmod: nf_hooks
depmod: nf_hook_slow
