Hello Experts, I have just now upgraded snort to 2.3.0RC2 on my HP 11.11 machine. I faced no problems during build process. It was a smooth install. Then I started testing all options. When I tested the -o option, bus error occured and core was dumped.It happend after few minutes after starting snort. CPU utilization was normal. The command that I executed was, snort -c /opt/iexpress/snort/etc/snort.conf -o But I tested again without using snort.conf file,then it works well. snort -l /var/log/snort -o I also tested the previous stable version 2.2.0 on HP-UX 11.11. I tested above said both options,I found no problem,it works well. The problem is only with snort -2.3.0 RC2,that to when I use "-o" option along with "-c" option. Anyone can help in this issue??
