 Posted: Thu Sep 14, 2006 2:58 pm Post subject: Iptables problem [SOLVED] |
 |
|
i have been following the iptables guide. after i compile iptables as modules in the kernel, and i then go modprobe ip_tables i get this error
| Code: |
FATAL: Error inserting ip_tables (/lib/modules/2.6.17-gentoo-r5/kernel/net/ipv4/netfilter/ip_tables.ko): Unknown symbol in module, or unknown parameter (see dmesg)
|
i run dmesg, and i get this error.
| Code: |
ip_tables: disagrees about version of symbol skb_copy_bits
ip_tables: Unknown symbol skb_copy_bits
ip_tables: Unknown symbol nf_register_sockopt
ip_tables: Unknown symbol nf_unregister_sockopt
ip_tables: disagrees about version of symbol skb_copy_bits
ip_tables: Unknown symbol skb_copy_bits
ip_tables: Unknown symbol nf_register_sockopt
ip_tables: Unknown symbol nf_unregister_sockopt
|
i have no clue on how to fix this. any help will be aprecieated
[/
edit: i had put this right after i compiled the iptables module into the kernel. after posting this, i unloaded the via_rhine and mmi modules from the kernel, and tried to load the iptables module, with no luck either. then, when i tried to get via_rhine back to work, i got an error, and this is the dmesg

It seems like a kernel and iptables version mismatch.
I would recompile the kernel and reemerge the iptables. It usually fixes those kind of problems (and don't forget to link the kernel directory in /usr/src as linu, it helps) |

i did just that, and i still get this.
| Code: | ip_tables: disagrees about version of symbol skb_copy_bits
ip_tables: Unknown symbol skb_copy_bits
ip_tables: Unknown symbol nf_register_sockopt
ip_tables: Unknown symbol nf_unregister_sockopt

im pretty sure that it has to do with something in the kernel itself....
wth is skb_copy_bits, nf_register_sockopt, and nf_unregister_sockopt.
im guessing that i have to do something with those modules in the kernel, either compile them or take em out. |

Did you 'make modules_install' after recompiling? Also, can you give us the output of the following...
| Code: | | ls -al /lib/modules/2.6.17-gentoo-r5/kernel/net/ipv4/ |
| Code: | | emerge -pv iptables |
Here are my netfilter options in my kernel:
| Code: | CONFIG_IP_NF_IPTABLES=m
CONFIG_NETFILTER=y
CONFIG_NETFILTER_XTABLES=m
CONFIG_NETFILTER_XT_TARGET_CLASSIFY=m
CONFIG_NETFILTER_XT_TARGET_MARK=m
CONFIG_NETFILTER_XT_TARGET_NFQUEUE=m

thankyou everyone for your help...
i got this fixed. It seems that the liveCD uses genkernel to compile the kernel. So it had the initramfs pointed in the grub.conf. That was the trouble i had, and thats why i had those errors.
all i did to fix this was redo the grub.conf and make it a non-genkernel boot.
thanks again for your time.  i hope this helps someone in the future. |
