>I was trying to install snort 2.9 on my RHEL 5.5 system. Initially i tried to install by downloading snort rpm from http://www.snort.org/downloads/265 but i failed because it generated error that libpcap>=1.0.0 is required to install snort 2.9. I decided to check my libpcap version using command ‘rpm -qa|grep libpcap‘ and found that libpcap-0.9.4 is installed on my system. After a bit googling and hit and trial, I got the following steps to install snort-2.9 on my RHEL 5.5 system.
step2. Move into /usr/local/src/libpcap-1.1.1
step3. Install libpcap in /usr/lib
step4. Downloaded daq from http://www.snort.org/downloads/263 and uncompressed it in /usr/local/src folder.
step5. Move into /usr/local/daq-0.2
step6. install daq-0.2
step7. Downloaded snort-2.9 from http://www.snort.org/downloads/269 and uncompressed it in /usr/local/src folder.
step8. Move into /usr/local/src/snort-2.9
step9. ./configure –with-mysql
step11. make install
I followed above given steps and snort-2.9 successfully get installed on RHEL 5.
