Ok, here we go:
First get the pluspack from:
http://asl.duncanthrax.net/pluspack-asl-3.x/pluspack-asl-3.x-1.tar.gz
copy the tarball to the ASL machine
Unpack the tarball in /var/chroot-report
execute pluspack/install.pl
re-login to update your environment
Note: remember that if you want to install programs you should add the --prefix=/pluspack and sometime the configure script might not detect your host type so you must add --host i686-pc-linux-gnu or something like this.
Now that we have the pluspack install lets get the snort tgz from:
http://www.snort.org/dl/snort-1.9.0.tar.gz
copy it to the ASL machine, untar it for example in /root
now we must get the client libs and header files form a machine with mysl already installed you must get all the files in /usr/lib/mysql or something like this depending where you installed mysql and copy them to your asl box to the same location
then copy the include files from /usr/include/mysql to the same location in your asl box
Now lets compile snort, go to /root/wherever extracted snort
and do ./configure --with-mysql
then make
then make install
and that's it, now all you have to do is install the snort rules, edit snort.conf and launch snort
and install the rc.d init script included in the snort package in the dir contrib.
