Hi,

Interesting stuff; glad to see things still happening with it. Thank you
for your work in providing this to the community; I personally find it very
useful.


Kind Regards,

 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
