See my other post...

"FYI:

I've added preliminary support for unified2 to SnortUnified.pm

http://www.snort.org/users/jbrvenik/Site/Blog/Entries/2007/10/21_Merry_Christmas_(or_whatever_you_like).html

short version

http://tinyurl.com/24v8xs

Pull trunk from SVN and have a go. I would be really appreciative of
feedback."

and as to what unified2 does...

It actually unifies output  :)

There is one file for all data types produced.

Currently the source defines the following.

#define UNIFIED2_EVENT 1
#define UNIFIED2_PACKET 2
#define UNIFIED2_IDS_EVENT 7
#define UNIFIED2_EVENT_EXTENDED 66
#define UNIFIED2_PERFORMANCE 67
#define UNIFIED2_PORTSCAN 68
#define UNIFIED2_IDS_EVENT_IPV6 72



Though I've only implemented handling for packets and (ids)events at the
moment.

That brings me to a relavant question.  What is the point of unified2
(aside from feature enhancements) if barnyarf is orphaned.

I am confused about barnyards future because the offical snort
training still uses this but its unmaintained and things like gid
support with mysql is broken unless you add on a 3rd party patch.

Is there some other application to take over barnyards function or is
the unified2 format for the commerial sourcefire products.

My understanding is that barnyard is basically orphaned and
unmaintained.  I asked about 2.8 support a while back and was told that
there was no plans to update barnyard.

Hi .*!

So I sent this message to the barnyard-users mailinglist but
it seems that this list is dead. :/

Because this is (somehow) related to snort I will resent the message
to this list ...

I've tried to run barnyard 0.2.0 (build 32) to process the
unified alert files generated by snort 2.8.0 but unfortunately
it dumps core. e.g.:

debian3164m:/var/log/snort#
Barnyard Version 0.2.0 (Build 32)
Segmentation fault (core dumped)

This happens on:

debian3164m:~# cat /etc/debian_version

debian3164m:~# uname -a
Linux debian3164m 2.6.8-12-amd64-k8-smp #1 SMP Thu Dec 7 18:44:52 UTC 2006

x86_64 GNU/Linux

with snort:

Running barnyard in the dry-run mode it says:

So I tried to recompile with --enable-debug but this doesn't even compile:

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../../src

-I/usr/include/pcap    -g -O2 -Wall -DDEBUG -ggdb -c dp_stream_stat.c

dp_stream_stat.c: In function 'StreamStatDpReadFileHeader':
dp_stream_stat.c:104: warning: format '%d' expects type 'int', but

argument 4 has type 'ssize_t'

dp_stream_stat.c:104: warning: format '%d' expects type 'int', but

argument 5 has type 'long unsigned int'

dp_stream_stat.c:112: error: 'StreamStatFileHeader' has no member named

'magic'

make[3]: *** [dp_stream_stat.o] Error 1
make[3]: Leaving directory

`/home/maus/tmp/barnyard-0.2.0/src/input-plugins'

make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/maus/tmp/barnyard-0.2.0'
make: *** [all-recursive-am] Error 2

It will compile if I comment the offending line in dp_stream_stat.c:112:
112: printf(" Magic          = 0x%X\n", file_header.magic);

but does that help if I compile it like this and submit the backtrace of

the

generated core file ?

Any help?

So long,

Andreas.

P.S.: I attached my barnyard.conf to this message.
