Hi Peter! There are 2 errors

1. root@nfsen:/# /opt/nfsen/bin/nfsen reconfig Argument "-z=lz4" isn't numeric in numeric eq (==) at /opt/nfsen/libexec/NfConf.pm line 236.

I'm seeing similar problems using FreeBSD's 1.3.11 package. It seems to stem from the fact that the hints file in /usr/local/var/nfsen/profiles-stat doesn't appear to have any useful data in it. It's read by the code for multiple tasks but I don't know where it's supposed to get updated with relevant local configuration values.

@fatherfbi - hmm -- I assume, your nfsen version is too old or nfdump too new. You should use the latest main repo. That should work with nfdump-1.7.x.

[fatherfbi]

@phaag I use nfdump v1.7.4 and nfsen v1.3.10, system Ubuntu 22.04.4 LTS

FWIW, the FreeBSD issue is that there is no install.pl used or included in the binary package so the hints file is never initialised. Not ideal but the following code will set some hardcoded values so that the other components don't complain.

#!/usr/bin/env perl

use lib "/usr/local/libexec/nfsen";
use NfSen;

my $hints = NfSen::LoadHints();

$$$hints{'subdirlayout'} = 1;
$$$hints{'nfdump'} = 7;
$$$hints{'version'} = "1.3.11";
$$$hints{'installed'} = time();

NfConf::LoadConfig("/path/to/nfsen.conf");
foreach my $source ( sort keys %NfConf::sources ) {
    my $port = $NfConf::sources{$source}{'port'};
    $$$hints{'sources'}{$source} = $port;
}

NfSen::StoreHints();

So, maybe the FreeBSD package could be patched accordingly.
