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

Hi Vincent,
After allot of try and error tests I discovered that libpcap 1.1.1 was the
culprit for the Segmentation fault error, I managed after some anguishing
compilations (i'm really new to the rpmbuild process, only 2 days ago ) to
build a libpcap 1.0.0 rpm with the specs file from your build.
Thank you for all your help.
Regards,
Ovidiu

Hello Vincent,
Thanks allot for your help. I managed to pass that error and
everything builds just fine, but when i try to run snort i get segfault :
kernel: device eth0 entered promiscuous mode
Nov 4 10:50:30 kernel: snort[8650]: segfault at 0000000000000010 rip
00000000004a072c rsp 00007fff7d712070 error 4
Nov 4 10:50:30 kernel: device eth0 left promiscuous mode
I compiled manually these versions and all works just well, I don't
know what the problem is. I'm at this since the morning and couldn't get
some good rpm's. Can you tell me how did you make the libpcap 1.1.1 rpm?
I will be glad if you can guide through some checks to see what is
the problems.
Regards,
Ovidiu

Hi Stanila,
I'm currently pushing 2.9.0.1-2 rpms built with --enable-zlib on that
website. I don't know if that will have any side-effects but I guess it
won't hurt.
You got the daq_ipq.* errors because daq didn't build the daq_ipq* modules
on your system (maybe due to a missing library). At any case, I've changed
the spec file to be more 'flexible', which should help it build on your
system (see daq-0.3-3.el5.src.rpm).
The updated list of RPMS is as follows:

Hi everybody,
I installed Vincent's
rpm's(https://www.redhat.com/archives/rhelv5-list/2010-November/msg00001.html)
on my Centos 5.5 system and after the installation when i ran snort -c
/etc/snort/snort.conf -T i got this error:
ERROR: /etc/snort/snort.conf(194) => Invalid keyword 'compress_depth' for
'global' configuration.
Fatal Error, Quitting..
I read on snort forum that this error appears because snort isn't
compiled with --enable-zlib option. So i installed the src rpm to try and
compile again snort, but when running rpmbuild i got this error:
checking for daq_load_modules in -ldaq_static... no
ERROR! daq_static library not found, go get it from
http://www.snort.org/.
I tried compiling daq separately, from src rpm provided by vincent, but
there i got this error:
RPM build errors:
File not found: /tmp/daqrpm-0.3/usr/lib64/daq/daq_ipq.la
File not found: /tmp/daqrpm-0.3/usr/lib64/daq/daq_ipq.so
Could somebody help me, I'm all out of ideas.
I'm kind of new on compiling packages, so any help will be great.
Thank you for your time.
