Dentro da pasta do ipp2p, existe tais arquivos:
#ls ipp2p-0.8.2
COPYING Makefile Makefile_old Module.symvers README ipt_ipp2p.c ipt_ipp2p.h libipt_ipp2p.c

Qual desses arquivos eu aplico sua patch??

Ex: patch -p1 < ipt_ipp2p.c ??

Depois de aplicar devo recompilar o kernel e depois compilar o ipp2p???

[alexandrecorrea]

nao.. o ipp2p roda sem necessidade de recompilar kernel.. eh um modulo apenas !!

[silvasp]

O comando para aplicar sua patch é este:


Ex: patch -p1 < ipt_ipp2p.c (o arquivo é este ?)


#ls ipp2p-0.8.2
COPYING Makefile Makefile_old Module.symvers README ipt_ipp2p.c ipt_ipp2p.h libipt_ipp2p.c

[alexandrecorrea]

cara pra aplicar patch eh

patch -p1 < arquivo.do.patch

faz dentro da pasta do ipp2p ...

[alexandrecorrea]

seguinte...

pega o arquivo de patch.. as linhas que tem - sao substituidas pelas que tem +

ai vc edita o arquivo ipt_ipp2p.c e faz as alteracoes MANUALMENTE !!

[silvasp]

Veja bem...

Reinstalei o slack 12 e compilei o ipp2p, para minha surpresa ocorreu tudo bem. Porém, depois que compilei o kernel o módulo do ipp2p não carrega.

Veja a mensagem:

#modprobe ipt_ipp2p
FATAL: Error inserting ipt_ipp2p (/lib/modules/2.6.21.5-smp/kernel/net/ipv4/netfilter/ipt_ipp2p.ko): Invalid module format

#dmesg
ipt_ipp2p: version magic '2.6.21.5-smp SMP mod_unload 686 ' should be '2.6.21.5-smp SMP mod_unload PENTIUMIII '


Informações

Slack 12 com smp
Processador: Xeon(opção marcada no kernel=Xeon/PentiumIII)

Antes de compilar o kernel, o ipp2p funcionou perfeito, mas após a compilação o módulo não carrega mais..

O que pode ser???

[silvasp]

Olá pessoal...

Finalmente conseguir resolver o poblema do ipp2p no slack 12.

Obrigado a todos que tentaram me ajudar!!!
