Description Nigel Smith 2021-04-19 04:10:14 UTC
Running softflowd on pfsense 21.02.2-RELEASE on a netgate SG-1100 (arm64) is failing to send any netflow traffic and is producing a segfault - see below (i've redacted the IPs)


```

There's no netflow traffic being sent by the firewall, and hence no traffic being received by the collector.

I'm not sure where to go next in terms of digging into the problem - any suggestions?

FYI I had first raised this with netgate who suggested I follow up with the maintainer of the package - see issue reported here: https://redmine.pfsense.org/issues/10436 . There's a separate support ticket where I have just been told:

> I checked with our development team on this issue.  Unfortunately Netflow is a third party package that we only "wrap up" to provide to pfSense.  As such, you will want to follow up with the package maintainer as there isn't much we can do here to provide assistance for this package as it is unsupported.  The best place to communicate is via the redmine and directly with the maintainer of the package.

Comment 1 Li-Wen Hsu freebsd_committer 2021-04-19 07:47:09 UTC
Since this is the issues tracking system of the FreeBSD project, the upstream of the PFSense, we might not be very helpful if this is due to any customization in the PFSense.  We're still willing to help, but it would be much helpful if you can test net-mgmt/softflowd with the supported FreeBSD versions and report if it work or not. If possilbe, testing with 13.0-RELEASE, 13.0-STABLE and 14.0-CURRENT is more preferred. Thanks.
