iptables on kernel2.4.1
i am not all that familiar with how a kernel calls its modules and what an
unresolved symbol even is.
i do know however, that i thought i had iptables correctly compiled into
the kernel as a module, but when i try to load the module, things go
south.
here is a snapshot of the kernel config and the error i get from modprobe
[*] Network packet filtering (replaces ipchains)
IP: Netfilter Configuration --->
< > Connection tracking (required for masq/NAT)
<M> IP tables support (required for filtering/masq/NAT)
<M> limit match support
< > MAC address match support
<M> netfilter MARK match support
<M> Multiple port match support
< > TOS match support
< > Unclean match support (EXPERIMENTAL)
< > Owner match support (EXPERIMENTAL)
<M> Packet filtering
<M> REJECT target support
< > MIRROR target support (EXPERIMENTAL)
< > Packet mangling
<M> LOG target support
< > ipchains (2.2-style) support
< > ipfwadm (2.0-style) suppor
and here is the output that i get when i try to manually load the iptables
module:
[~/ipchains] Yes, my master? >modprobe ip_tables
