Fysika ekana ola ta parapanw. Loipon pragmati den exw balei modules (ola
einai mesa ston kernel) opote katalabainw giati to 'make
modules_install' den kanei tipota. Alla den 8elw na exw dynamika
modules,
peirazei;  :-)
Ela omws poy to ipchains otan to trexw 8elei swnei kai kala na kanei
insmod to ip_tables module!
Ebala tote me to xeri to ip_tables.o sto /lib/modules/... kanw kai ena
depmod kai perimena na kanei kati endiaferon, alla dystyxws phra ayto:

/lib/modules/2.4.2-2/kernel/net/netfilter/ip_tables.o: couldn't find the
kernel version the module was compiled for
/lib/modules/2.4.2-2/kernel/net/netfilter/ip_tables.o: insmod
/lib/modules/2.4.2-2/kernel/net/netfilter/ip_tables.o failed
/lib/modules/2.4.2-2/kernel/net/netfilter/ip_tables.o: insmod ip_tables
failed
iptables v1.2.1a: can't initialize iptables table `filter': Table does
not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Ayto me to 'kernel version' me enepneyse na kanw diafora  '/sbin/depmod
-ae -F /boot/System.map' mpas kai 3ypnhsei, alla pali tipota.
