[PLUG] TRYING to configure / 2.4.3 kernel

Since trying to compile my own 2.4.3 kernel, I've made a lot of
configuration errors.

I'm slowly getting the use of my h/w components back!  Scanner is up and
running again....

My bootup still has some error msgs which can be ignored for the time

However one thing I used to use is IPChains under the 2.2 kernel.
Under the 2.4 kernel, according to the Documentation/Changes file of the
2.4 kernel source, IPChains has now been superceded by Packet Filtering,
which apparantly works differently from IPChains.

However when configuring the 2.4 kernel, there is an option to enable
2.2 support for IPChains.
I enabled both support for IPchains, and all the packet filtering
options that I thought I might need, all as modules

I've had to change some of the default modprobe paths, putting the
following paths into the
/etc/modules.conf file -

path[ipv4]=/lib/modules/'uname -r'/kernel/net/ipv4/netfilter  ***
ipchains path ***

When I now try to run depmod now, I get the following error msg:

[root@NAV-111 linux]# /sbin/depmod
depmod: *** Unresolved symbols in
depmod: *** Unresolved symbols in
depmod: *** Unresolved symbols in
depmod: *** Unresolved symbols in
depmod: *** Unresolved symbols in
depmod: *** Unresolved symbols in

When I try to run modprobe, I get the following error msg:

[root@NAV-111 linux]# /sbin/modprobe ipchains
/lib/modules/2.4.3/kernel/net/ipv4/netfilter/ipchains.o: unresolved
symbol nf_unregister_hook
/lib/modules/2.4.3/kernel/net/ipv4/netfilter/ipchains.o: unresolved

/lib/modules/2.4.3/kernel/net/ipv4/netfilter/ipchains.o: unresolved

/lib/modules/2.4.3/kernel/net/ipv4/netfilter/ipchains.o failed
/lib/modules/2.4.3/kernel/net/ipv4/netfilter/ipchains.o: insmod ipchains


Am I using too old a version of modutils, if the default module paths of
MODPROBE are the older module paths under kernel 2.2, rather than the
module paths I have under kernel 2.4?

My modutils version is:  modutils-2.4.2-5.  (It's the latest RPM
available for RH from

What does the error msgs mean by "unresolved symbol"?

How do I go about fixing all this stuff???
