Suricata bug

tcsac

@tcsac:

suricata -T provides the same thing:
25/12/2014 – 10:37:22 - <error>- [ERRCODE: SC_ERR_FATAL(171)] - failed to open file: /usr/local/etc/suricata//suricata.yaml: No such file or directory</error>

On pfSense, you can't just run "suricata -T" without also providing the proper YAML config file path. PBI packages on pfSense are configured to use a special path.

How did you install Suricata on this box? Was is it via System…Packages...Available Packages?

What prints in the system log when you attempt to start the Suricata service from Services…Suricata by clicking the red X icon?

~~Also, the paths for these settings are incorrect:

Installation prefix (–prefix): /usr/local
Configuration directory (--sysconfdir): /usr/local/etc/suricata/

They should read /usr/pbi/suricata_amd64/ instead of /usr/local.~~

Last edit to scratch the statements above … the paths are apparently different on 2.2 versus 2.1 (which I was comparing to). The /usr/local prefix is OK on 2.2 as that is what is showing on my currently working 2.2-RC virtual machine.

Maybe that's part of the problem? On my box at least, /usr/local/etc/suricata/ doesn't even exist. If I search for suricata.yaml, the only file that I find is:

/usr/pbi/suricata-amd64/local/etc/suricata/suricata_23278_pppoe0/suricata.yaml

I'm guessing that's the problem…?

The PBI wrappers should take care of directing things to the real path. I just noticed that you are trying to use Suricata on a PPPoE connection. That is not currently supported by the underlying binary (it's not a GUI package or pfSense limitation, it is a limitation of Suricata on FreeBSD).

By the way, here is what I would have expected as the remainder of the suricata.log contents …

Would be nice if the package description called that out. It's a pretty big gap (I realize it's on the upstream, but we could at least have a warning)

I will see about adding a note to the DESCR tag in the pkg_config entry for Suricata warning that PPPoE interfaces are not fully supported.

I had the pfSense Team recompile the Suricata binary so that this parameter should now say "no" instead of "yes" –


GCC march native enabled:                yes

You can see this by executing

suricata --build-info

from the command line.

This can be a problem on some platforms where the native CPU does not match up closely with the CPU of the package builder systems on the pfSense Repository side. When this parameter is set to "yes", the C compiler attempts to auto-detect the compiling machine's CPU and optimize the produced machine code. This is generally OK except for when there are some differences in supported instructions (for example, compiling on a Xeon but running the produced code on a Pentium). The Suricata binary from upstream defaults to enabling this parameter. It works fine so long as you compile and then run Suricata on the same hardware. In a package repository environment where the binary packages are built on one CPU architecture but then potentially executed on several different architectures, there can be issues.
