Here is the files i have installed

libpcap-0.7.2.tar.gz
went ok but then i tried to install the rpm it said the package was already install

do you need the gd in your php? if no try config php with gd.

sorry i am a bit new to this wgat do you mean the command i have to get working is:-

./configure --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config-file-path=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlib-dir=/usr/local --with-gd

this has gd at the end

There are a few things that can go wrong during this configure step. The most common is that you have asked for an option and that the
configure script can not find the files required to enable this option in PHP.  Chances are you can provide the full path to the base directory under which the related files were installed.  For example, if you have installed the GD library in /opt/gd which means that /opt/gd/include has your GD header files and /opt/gd/lib containsyour GD library files, you would use --with-gd=/opt/gd

the above is the installation instruction of PHP and if you using gb you have to specify the GD library where your installed, so if you sure you need the GD find the library path of it and put it like  --with-gd=/path-of-gd/gd

i tried what you said please view below for the command i typed:-

./configure --x-libraries=/usr/lib/ --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config-file-
path=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlib-dir=/usr/local --with-gd=/root/snortinstall/php-4.3.
3/ext/gd/ --with-jpeg-dir=/usr/lib

but i got the same error see below this is the last line of the error:-

configure: error: libjpeg.(a|so) not found.
[root@linbox php-4.3.3]#

rpm -qa | grep libjpeg
You need to see two lines: libjpeg and libjpeg-devel

Why do this the hard way. RedHat 9 is shipped with a perfectly useable Apache and PHP. It would make more sense to me to install the Apache & PHP from your distribution and then configure it for Snort/ACID. That's what I do and it works quite nicely, thank you.

The same goes for mysql. The ./configure line that you quoted also contains --with-mysql=/usr/local/mysql - This is not where the RedHat package gets installed. So follow jlevie's advise and start out with the RedHat packages.

If you still decide that the RedHat packages do not have everything you need, the better way to do this is to start with the source RPM packages and modify the spec files. This way, you are getting a RPM package at the end that can easily be removed again.

ok i will go with the redhat way the reason i went this way is because i was just following the steps in the downloadable PDF from www.internetsecurityguru.com, if i do it the redhat the manual maybe be usless to me i will give it one more shot with khkremer advice if that don't work then redhat way it is.

i did type

[root@linbox root]# rpm -qa | grep libjpeg
libjpeg-6b-26

and got the above result, but what does it mean

This means that you don't have the libjpeg-devel package installed. Install this from your RH CDs.

I looked briefly at the PDF file you referenced, and I don't see a good reason to compile all these packages from scratch. You should still be able to follow the instructions, even when you take the pre-installed packages. You will have to adjust a few paths, but this should not be too complicated.

rpm -ql <package name>

will list all files that belong to a package, so rpm -ql mysql will list all mysql files. This should allow you to identify where the files references in the PDF file are on your system.

i have already installed mysql, i am on page 13 of the manual if i get libjpeg-devel then i shoul be ok right ? i will get libjpeg-devel then give the command below another go:-
./configure --x-libraries=/usr/lib/ --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config-file-
path=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlib-dir=/usr/local --with-gd=/root/snortinstall/php-4.3.
3/ext/gd/ --with-jpeg-dir=/usr/lib

i seem to be getting closer now i get the same error but with a different file:-

after running the command:-
./configure --x-libraries=/usr/lib/ --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config-file-
path=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlib-dir=/usr/local --with-gd --with-jpeg-dir=/usr/lib

i got the error:- please view last line
