Re: [rhelv5-list] snort 2.9.0 Centos 5.5

[vincent () cojot name]

Hi Ovidiu,

There were some other reports on snort-users that 2.9.0.x was segfaulting 
on rhel5.5. Like you already did, I found out that the segfault was 
related to libpcap1. I also noticed the following:

# snort -i eth0
# snort --daq pcap -i eth0
(segaults immediately after 'Initializing daemon mode')

# snort --daq afpacket -i eth0
(works fine but then it doesn't use pcap).

I do not know yet if we're running into this issue because of 
libpcap-1.1.1 or because of my own libpcap1 packaging. I would have to dig 
into the daq library and how it calls libpcap for that.

I'm CC'ing the snort-users list on this since it appears at least someone 
there (Jason Wallace) knows more about this issue. Jason said that getting 
rid of lib/snort_dynamicpreprocessor//lib_sfdynamic_preprocessor_example.so in 
your snort.conf might fix that issue.

Regards,

Vincent
