hi,

which snort binary are you running?
1.9.0 created a binary /usr/local/bin/snort
1.9.1 created a binary /usr/local/bin/snort_inline

You do also have a configured and working version of 
snort on the same machine too right?
no. i only compiled 1.9.0 and 1.9.1 inline

If you do not have a working and running version of
snort then you will not have a snort.conf.
i copied /opt/packages/snort_inline-1.9.1/etc/* /etc/snort/

As for the iptables....you did
"make" "make install" && "make install-devel" right?
yes


----------------------------

i did the following

-installed RedHat8.0 minimal
-updated all packages over RHN
-get kernel-2.4.18-26.8.0 from RHN
-installed libnet1.0.2a
-installed iptables-1.2.7a with make install-devel
-compiled snort-inline1.9.0 with --enable-inline
-compiled snort-inline1.9.1 with --enable-inline

---------------------------

snort-inline1.9.0

work well for a few minutes till i get an segmentation fault
