LARTC - Apr 2007 - ipp2p: error loading kernel module

Hi,
I get this error when trying to insmod the ipp2p kernel module:
"insmod: error inserting ''ipt_ipp2p.ko'': -1 Invalid
module format"

in the kernel log: "ipt_ipp2p: disagrees about version of symbol
struct_module"

Kernel version 2.6.20.4
iptables version: 1.3.5
ipp2p version: 0.8.2 (latest)

Anyone tried ipp2p with kernel 2.6.20?

Best Regards Niclas Bentley

Hi again,
I wrote this a few days ago....Isn''t there anybody using ipp2p and
linux
kernel 2.6.20?
I think ipp2p would be very useful in order to identify bittorrent
traffic...

I don''t - maybe you should cc the maintainer aswell.

As for bittorrent - there may be easier (and fairer) ways, like per user 
  shaping or if you are doing QOS for yourself use a client that can 
bind to a different IP.

Hi,

I''m using ipp2p v0.8.2 under kernel 2.6.20 - especially to shape my
son''s bittorrent usage :)
I had the same problem first, then it took me several steps/attemps to make it
work but it is now.
Those are the steps I followed (probably an overkill but I wanted all features
available for Shorewall and multiple ISP routing)
1, get the clean kernel source and symlink it to /usr/src/linux (it saves you
some mistakes to properly identify the location of your kernel source)
2, get the latest iptables source, symlink to /usr/src/iptables
3, get the ipp2p source
4, get the latest patch-o-matic-ng
5, get Julian Anastasov''s latest giant patch for 2.6.20

6, run the patch-o-matic/runme and apply all features all features
7, run the patch-o-matic/runme ipp2p
8, run make menuconfig
9, apply Julian''s patch on the kernel
10, run make menuconfig & make
11, compile iptables against this kernel source (don''t forget to set
the proper PREFIX to your distro)
12, compile the ipp2p code against this kernel source
13, install the new kernel: make modules modules_install install
14, optionally you have to copy the ipt_ipp2p.ko to the proper modules folder
and copy libipt_ipp2p.so to iptables''s lib folder

There could be steps not necessary in this process but it is working now for me
now.

Hope this helps,
Andras
