Re: OpenFPC Daemonlogger Segfault Through OpenFPC

["Leon Ward (leonward)" <leonward () cisco com>]

Hi.

In fact I've put a load of effort into ofpc recently. After a couple of requests I've moved the code to GitHub, that's 
one of the reasons why you won't have seen any commits to the google code svn repo.

It's working really well for my needs right now and I've added some new cool features like searching flow data from the 
cli. Once I've finished off distributed flow searching (via openfpc proxy to multiple session databases on remote 
nodes) I'll wrap another release and package it up again.

There is a load of other stuff I could talk about, but I'll wait until it's ready to release and out together a blog 
post/install video etc.

It's good to hear people are using it.

Hi,

I seem to have it now, reinstall openfpc, daemonlogger etc on both boxes and it was fine. On one of the boxes I did 
find bro files taking up to much space in the tmp and not being cleaned so the disk was going "oh time to roll over" 
right away so cleaned that up to and that one also started working so it might have been a combination or different 
issues just coming up at same time. So everything looking fine again :).

Thanks for the help and I look forward to seeing more stuff with daemonlogger :). Between this and openfpc it does this 
job very nicely for my needs & requirements right now.


Thanks,
Kevin

So we run OpenFPC on CentOS (now at 6.5) and when we've had problems, a reinstall of the package has helped.  Have you 
gotten any of the recentish changes that had gotten made in the scripts?  He moved the code tree to Google and there 
have been some fixes since the last zip on the old website.

https://code.google.com/p/openfpc/source/list

the /etc/init.d/openfpc-daemonlogger command calls openfpc which runs daemonlogger like this:

/usr/local/bin/daemonlogger -d -f /etc/snort/bpf.txt -i eth1 -l /var/log/snort/fpc -M 75 -s 256M -p 
openfpc-daemonlogger-<sensor name>.pid -P /var/run -u snort -g snort -n <sensor name>.pcap

Try that manually.. if that works, then it's a openfpc/perl/library issue.

On fedora we had to roll back perl-Filters due to some new changes that broke the client, but it has seemed stable on 
our servers

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

Hi,

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
