Updated to build with ndpi from ntop.org

[lucianocoutinho]

Hi,

I try to build ndpi-netfilter last week and got a few errors, then I made these changes and now at least I can build the module. I hope this can be useful, if there is any issue on this commit, please let me know.

Thanks.

I am struggling to build your version. I want to use the new ndpi version but when I build your code i get the LONG_STRING error, I applied the fix suggested by another user by adding the #define protocols on the correct file, but now it gives me an error every time I build and it reached the http protocol. Any clues? I am trying it on Debian 6.

Hi @lucianocoutinho, i've succesfully built the module with some warnings related to the ahocorasick library.
But when i try to depmod that module it gaves me this error:

FATAL: Error inserting xt_ndpi (/lib/modules/2.6.32-5-amd64/extra/xt_ndpi.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and dmesg:

xt_ndpi: Unknown symbol ac_automata_init
xt_ndpi: Unknown symbol ac_automata_search
xt_ndpi: Unknown symbol ac_automata_reset
xt_ndpi: Unknown symbol ac_automata_finalize
xt_ndpi: Unknown symbol ac_automata_add
xt_ndpi: Unknown symbol ac_automata_release

have you any idea how to fix this?

Thank you in advance

Try this (works for me)
vim src/Makefile

...
${NDPI_SRC}/lib/ahocorasick.o
${NDPI_SRC}/lib/node.o
${NDPI_SRC}/lib/sort.o
...

all:
if test -d ${NDPI_SRC}; then
cp ${NDPI_PATH2}/* ${NDPI_SRC} -R;
else
mkdir ${NDPI_SRC};
cp ${NDPI_PATH2}/* ${NDPI_SRC} -R;
fi
cp ${NDPI_SRC}/lib/third_party/src/.c ${NDPI_SRC}/lib -R;
cp ${NDPI_SRC}/lib/third_party/include/.h ${NDPI_SRC}/lib -R;
cp ${NDPI_SRC}/lib/third_party/include/*.h ${NDPI_SRC}/include -R;
make -C ${KERNEL_DIR} M=$$PWD;
rm -r ${NDPI_SRC}

Hello,

any idea how can I compile the ndpi-netfilter? I'm receiving the same error as SwissBureau, related with LONG_STRING and SHORT_STRING. I'm trying to build on debian 7, kernel 3.2, latest ndpi from ntop and the current master version. Returns the following:

libxt_ndpi.c:33:34: error: ‘NDPI_PROTOCOL_LONG_STRING’ undeclared here (not in a function)
libxt_ndpi.c:34:35: error: ‘NDPI_PROTOCOL_SHORT_STRING’ undeclared here (not in a function)
libxt_ndpi.c:34:1: error: initializer element is not constant
libxt_ndpi.c:34:1: error: (near initialization for ‘prot_short_str[0]’)
libxt_ndpi.c: In function ‘ndpi_mt_init’:
libxt_ndpi.c:116:25: warning: unused variable ‘info’ [-Wunused-variable]
make[2]: *** [libxt_ndpi.o] Error 1

What can I do? Thank you!

I managed to pass that error, stumble in various protocols missing , seem to me that this ndpi-filter doesn't work with last version of ndpi. Can you please tell me with which svn version should work ?
thanks!

I'm also not getting past this error. I've tried the other netfilter patches listed incomments but they don't build for me either.

Does anyone know the most recent version of nDPI that this builds against?

thanks betolj, I did find that I can get it to build, but it's not actually matching anything :/

Hi, Unfortunately this module is incompatible with nf_conntrack_netlink.

And, unless you recompile the kernel with the patch, the module
nf_conntrack_netlink can not be loaded into memory (but you will have
problems with conntrack tool).

rmmod nf_conntrack_netlink
modprobe xt_ndpi
