Lack of full ipv6-support

[oscarminus]

Hi firnsy,

i am using barnyard2 version 2.1.14 build 337 with ipv6 support enabled. For visualisation i use snorby in the actual version. I realized that snorby displays ipv6-adresses as wrong ipv4-adresses.

The cause seems to be, that barnyard2 handles ip-adresses as unsinged integers when writing them to the database. This works for ipv4 but obviously breaks with ipv6. I didn't find any commit or issue within the last years wich mentioned this behavior. I can't imagine that i'm the only one who runs in this problem.

Are there any plans to implement a different way of handling the ip-addresses? Of course, not only barnyard needs to be changed, but this is one part in the whole setup.

Greetings

Hi, I'm having the same problem with yours when integrating Barnyard2 with Snort. It writes 0 in the IP_SRC table and an integer in decimal to represent IPv6 which, in my view, is incorrect.

Has anyone managed to resolve this error?
