Add custom protocol about ndpi-netfilter

[betolj]

You cant do this, yet.
I think that: the best way to filter url is made with proxy servers, like squid (in userspace)

I think what rsweerarathna has in mind is the custom protocol definitions that you can set with ndpi on ntop-ng.

Hi betolj,
I have change nDPI code to identify the IFLIX as a protocol. It works with ndpiReader example and identifies all the flows as screenshot attached.
make_output.txt
. I changed only two files as mentioned in ntop/nDPI#127
After changing these files i replace your netfilter module "ndpi_content_match.c.inc" and "ndpi_protocol_ids.h" with my updated files.
Now it's giving some errors which attached here. Can you please help me to fix them? or just let me know what are the source files i should update to fix this.

Regards,

make_output.txt

I had ndpi-netfiler older version.
Now i installed the latest ndpi-netfilter code and then replace that two files. now it's giving some different error. see the screenshot.

There are still remnants of old nDPI version.
For example: the TDS protocol has been moved/replaced to MSSQL_TDS.

So, don't try to use the old project directory.
Unpack and build again in another directory and move your files for this
path too.

The latest version now includes OCS.
But, if there are new changes (custom protocol), you need to fix this manually. You can't overwrite the file directly. The older structure is incompatible.

It's need to include the nDPI ID in the file "/usr/src/ndpi-netfilter/src/xt_ndpi.h" too.
