[Snort-users] OpenFPC Daemonlogger Segfault Through OpenFPC

What’s the command line that’s being fed to DaemonLogger?  That’d probably be the first place to start looking.  That’s a pretty weird error, is there a core dump?

Subject: [Snort-users] OpenFPC Daemonlogger Segfault Through OpenFPC


I know this is an older tool which isn't supported but I use it for ease of integration into snorby & also that it stores onto disk and then fetches on request making it better for my sensors as PCAP solutions like moloch are just too resource intensive so I would appreciate any help kindly given (or suggestions for another suitable maintained PCAP option similar in nature).

My systems were updated recently and fine; now following reboot daemonlogger segfaults when run through openfpc so I am not able to get PCAPs. If I run daemonlogger say with just daemonlogger -i eth1 it is fine and logs PCAPs but when using openfpc -a start it says it starts and then in status it is stopped and shows in /var/log/messages as segfault error with same memory location and things for each system:

System 1 Error - kernel: : daemonlogger[23570]: segfault at 0 ip 0000000000402a0a sp 00007fffbc8be100 error 4 in daemonlogger[400000+7000]
System 2 Error - kernel: : daemonlogger[3392]: segfault at 0 ip 0000000000402a0a sp 00007fff0e1e8c90 error 4 in daemonlogger[400000+7000]

Running the queue daemon in debug mode and things is fine and shows nothing but I have no idea how to debug daemonlogger through openfpc. Some other points:

- Daemonlogger Version1.2.1 (latest version installed)
- Latest openfpc
- System running Centos 6.4
- SELINUX tried relabel, disabled etc.

Thank you for any help in advance.

Kindest Regards,
Kevin Ross
