Snort on OSX 10.5.2 "bus error"


Posted by thetravellor on April 03, 2008 15:55:15


Am trying to set up Snort on OSX 10.5.2 / PowerPC

Latest source code, downloaded and compiled
Latest registered rules
Modified snort.conf so it looked for dylib instead of .so
Set up Snort database and tested it.
MAMP pro (Apache 2 / MySQL 5 / PHP 5)
Installed base and adodb from Macports

When I run snort on the command line, it all loads, then after a few seconds I get a cryptic "bus error" and the program exits.

Has anyone encountered this, or any ideas how I might fix or bypass it.

sudo /usr/local/bin/snort -i en1 -c /usr/local/etc/snort/snort.conf

When you compiled snort did you follow the instructions in the INSTALL file?

* MAC OSX
---------
On Darwin (maybe others), the configure script shipped as part of the
source distribution needs to be recreated. To do this, run the
following commands:

aclocal -I m4
autoheader
automake --add-missing --copy
autoconf

If you plan to use the dynamic plugin capability (ie,
configure --enable-dynamicplugin), snort needs to be linked using
the two level namespace. To do this, set the LD_TWOLEVEL_NAMESPACE
environment variable to something prior to running configure.
An example:

$ export LD_TWOLEVEL_NAMESPACE=1
$ export MACOSX_DEPLOYMENT_TARGET=10.5
$ configure --enable-dynamicplugin
