i'm trying to setup my iptables and i'm encountering resistance from the loading of modules (depmod -a specifically). i think this is b/c i've been fiddling with the kernel and there may be a problem with (a guess based on the threads i've read) system maps.

if i'm in the wrong on the above assertion, what is it that determines the output of depmod?

during my kernel compiles i've found it convenient to make a number of directories into which i place my bzImage and its respective system map. my concern is that upon booting the computer the wrong (one i don't want to use) system map will be loaded from /boot/System.map (when the one i want to use is in /boot/alt1/System.map). is my concern about system maps and their locations valid or does the system map get loaded from whichever directory holds the kernel image?

the root of all this worry is my firewalling script not working and spitting out

root@myth:/etc/rc.d# ./rc.firewall

suggestions?

i think u didn't enable some kernel modules, so go to "/usr/src/linux", and do "make xconfig" and enable whatever those things are, i dunno. then just compile the kernel, i think u know how to do that. :-)

when you recompile the kernel, the old modules will not
work anymore, depending on what you've changed, and
they don't get deleted when you install the new ones. so
if you don't want those messages, either delete the
modules directory before you install the new ones, or
delete the old ones that don't work after you've installed
the new ones.
