Hello!
I use nfsen-1.3.8.
The problem: nfsen incorrectly deletes files with this pattern -
nfcapd.current.* - when "%sources" in nfsen.conf have "'port' => '0'" (for
example:
%sources=(
'test' => { 'IP' => '192.0.2.1', 'port' => '0', 'col' => '#000080', 'type'
=> 'netflow' },
);
For the above configuration nfsen must not start/stop the collector because the
last is managed outside nfsen. And when nfsen deletes nfcapd.current.* the
collector cannot save current netflow data because of deletion of the
appropriate file by nfsen.
I propose to not delete the collector's current stat file for the above
configuration. The working patch follows.
