FATAL: Module xt_opendpi not found.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. make modules_install
2. cp ipt/libxt_opendpi.so /lib/xtables
3. modprobe xt_opendpi

What is the expected output? What do you see instead?
FATAL: Module xt_opendpi not found.

What version of the product are you using? On what operating system?
2.6.38-8-server #42-Ubuntu

Please provide any additional information below.
For some reason I can't get iptables to work with opendpi, the help function 
comes up and all the options eg: --bittorrent etc, but I can't put the likes of 
this in...

iptables -A FORWARD -s 172.16.20.0/24 -m opendpi --http
iptables -A INPUT -s 172.16.20.0/24 -m opendpi --http -j ACCEPT
iptables -A OUTPUT -s 172.16.20.0/24 -m opendpi --http -j ACCEPT

For some reason it just keeps coming up with...

iptables: No chain/target/match by that name.

If I take the -m opendpi out the rule works just fine.

Cheers
Dan

what happens if you try

sudo insmod `find -name xt_opendpi.ko`

instead of 'modprobe xt_opendpi' ?

the .ko file doesn't appear to exist on this box?

In that case, does 'make all' executes successfully till the end? If the file 
src/xt_opendpi.ko does not exist, it means something went wrong during 
compilation.

Can you try 'make -C src clean all > make.log 2>&1' and attach here the file 
make.log?

Oh thats odd, it doesn't appear to be able to see the src/ directory
underneath wrapper/

<code>
~/opendpi-1.3.0/wrapper# make all
make -C ipt
make[1]: Entering directory `/root/opendpi-1.3.0/wrapper/ipt'
if test -d opendpi_cpy; then \
        cp /src/* opendpi_cpy -R; \
    else \
        mkdir opendpi_cpy; \
        cp /src/* opendpi_cpy -R; \
    fi
cp: cannot stat `/src/*': No such file or directory
make[1]: *** [all] Error 1

I forgot something in the command-line. You need to specify the OPENDPI_PATH 
variable:

OPENDPI_PATH=/root/opendpi-1.3.0 make all

whoops sorry about my signature coming up.

I don't understand. if that part compiles correctly, you should be able to do 
'insmod src/xt_opendpi.ko'.

its very odd, I just don't get any errors during compiling the opendpi
package

root@camp1inet:~/opendpi-1.3.0# insmod src/xt_opendpi.ko
insmod: can't read 'src/xt_opendpi.ko': No such file or directory
root@camp1inet:~/opendpi-1.3.0# cd wrapper/
root@camp1inet:~/opendpi-1.3.0/wrapper# insmod src/xt_opendpi.ko

could we get the compilation log please?

OPENDPI_PATH=/root/opendpi-1.3.0 make clean all > make.log 2>&1

you're not compiling the netfilter wrapper here, but opendpi sources! the 
kernel module is part of the netfilter wrapper:

cd /root/opendpi-1.3.0/wrapper
OPENDPI_PATH=/root/opendpi-1.3.0 make clean all > make.log 2>&1

yes of course, sorry, that was my bad...
we definitely get errors there...

I think this is because your kernel is not configured properly with connection 
tracking events enabled.

You should carefully read both files README and INSTALL in the 
/root/opendpi-1.3.0/wrapper folder.

Then, I don't know how easy/hard it is to recompile a kernel from source in 
Ubuntu... refer to the ubuntu documentation/wiki/forums for that.

Best regards,
Lionel

ah ok, I had thought it might have not compiled the new option correctly.
Thanks all for your help.

Hi Guys, I've recompiled kernel with the option turned on but still having

would I have to roll back my kernel to the supported version?
