Don't install Snort from RPM.  Compile from scratch.  IMO this is the
way to go.

Hi Juan, 

Been following the conversation here.  The problem isn't that no one
uses Linux.  The problem is its free, which equals no vendor, which
equals no support.  You can't just call up your local O/S vendor to ask
for help, unless you have purchased a support contract from someone like
Redhat.

The second problem is you have come to a snort users area.  No one here
supports Linux, they help with Snort.  There is a certain assumption of
Linux understanding required before posting here.  Try asking for advice
on a Fedora users mailing list or forum
(http://www.linuxforums.org/forum/viewforum.php?f=35).  You will find
that everyone here uses their own little flavour of Linux that works for
them and this may not be the one your using.  For example I use Debian.

The third issue here is you just can't set up an Enterprise Snort
solution in one day.  It took me 2 months of lab work and build testing
just to get the initial build.  After that its constant updating and
review.  Once you get these things running you just can't walk away.
Its all fine and dandy to use a build guide from someone like Patrick
Harper (Best guide I have see so far. Thanks.) but in the end if you
don't take the time to understand your going to be no further ahead. 

I can see your are frustrated and this email won't help your problem.  I
just hope it will help you understand and point you in the right
direction.

I tried the command an hour ago: 

This is what I recive: 

[root at ...12378... snortinstall]# yum install openssl 
Gathering header information file(s) from server(s) 
Server: Fedora Core 1 - i386 - Base 
Server: Fedora Core 1 - i386 - Released Updates 
Finding updated packages 
Downloading needed headers 
openssl is installed and is the latest version. 
No actions to take 

I cant belive this is happening to me.... 

I found that it says the same about allmount all the dependencis in
looking 
for. 

I cant belive I will need to reinstall a sensor just because of
dependencis 
problems. Now I understand why nobody uses Linux. 

Maybe to insert the distribution cd's and install every package ? 

I must get it working !!! 


Thanks !!

Juan, 
 try using yum to install any missing packages. Yum is new with fedora 
core 1. the command would be something like this to install ssl: 
yum install openssl 

if you don't have yum, you will probably need to get it off an ftp site 
or the cds you installed with. 

This way you will get all the dependencies with the package and a lot 
fewer headaches. You will still have to install your snort rpm by hand. 

I hope this helps some.

[snip tale of woe] 

All the problems you're experiencing are essentially down to your 
self-acknowledged lack of experience with Linux distributions and 
commonly-used packages within. None of your problems are 
snort-specific, so 
I respectfully suggest that you get some books and/or training on the 
distro you're using, then revisit setting up a snort-based NIDS. You 
need 
to learn to walk before you can run. 

As far as recommended books: <http://www.rpm.org/max-rpm/>, 
<http://www.oreilly.com/catalog/learnredhatentlnx>, 
<http://www.oreilly.com/catalog/linuxnut4/>, 
<http://www.oreilly.com/catalog/esa3/>, 
<http://www.oreilly.com/catalog/msql2/>. 

Alternatively, if you just want a working NIDS, you might be better-off 

getting your employer to shell out some cash for one of the ready-built 

snort-based NIDS appliances, such as Sourcefire. 

Best Regards and Good Luck! 
Alex.
