Hi,
I've set up NFSen (1.3.6p1) on a Machine running FreeBSD 10.0.
Installed all prerequisites, i.e.
apache24-2.4.10
mod_php5-5.4.34
php5-5.4.34
perl5-5.16.3
etc.
In nfsen.conf I've got entries for the respective routers delivering
their netflow data:
...
'isp-router-1' => { 'port' => '2600', 'col' => '#00008B', 'type' =>
'netflow' },
'isp-router-2' => { 'port' => '2601', 'col' => '#0000ff', 'type' =>
'netflow' },
'core-router' => { 'port' => '2602', 'col' => '#ff0000', 'type' =>
'netflow' },
'core-router2' => { 'port' => '2603', 'col' => '#ff6600', 'type' =>
'netflow' },
...
I ran the "install.pl" in order to get everything in place and did an
"nfsen start". Up to this point everything went fine - here's the output from
starting NFSen:
[root@mybox ~]# nfsen start
Starting nfcapd:(core-router2)[2958] (core-router)[2961] (isp-router-1)[2964]
(isp-router-2)[2967]
Starting nfsend.
[root@mybox ~]# nfsen status
NfSen version: 1.3.6p1
NfSen status:
Collector for (core-router2) port 2603 is running [2958].
Collector for (core-router) port 2602 is running [2961].
Collector for (isp-router-1) port 2600 is running [2964].
Collector for (isp-router-2) port 2601 is running [2967].
nfsen daemon: pid: [2969] is running.
[root@mybox ~]#
But then the troubles started:
1) Error displayed on webpage
The error
ERROR: nfsend socket_read() communication error: Connection reset by peer!
is displayed in red near the top of the page.
2) No data displayed on the webpage(s)
On the webpage no data is displayed (graphs remain empty) but on the
other hand data definitely is coming in. For exampl files in
/var/nfsen/profiles-data/live/isp-router-1/2014/10/31 grow both in
size and number. So data seems to arrive and being "captured" by
nfdump though.
3) Can't stop nfsen-related processes
When trying to stop nfsen with "nfsen stop" nfsen related processes
refuse to stop:
Shutdown nfcapd: (core-router2)[2958].......... Process [2958] does not want to
terminate!
(core-router)[2961].......... Process [2961] does not want to terminate!
(isp-router-1)[2964].......... Process [2964] does not want to terminate!
(isp-router-2)[2967].......... Process [2967] does not want to terminate!
.
Shutdown
nfsend:[2969].....................................................................................................................
#
Running "nfsen stop" a second time stops the "nfcapd" processes but
not nfsen (I still get the "Process ... does not want to terminate"
for the nfsen process.
BTW, the log doesn't say anything about an error or such

So here are my questions:
o) Has anybody seen these problems before?
o) Any known cure agains this?
o) Any way to turn on debug/logging so I get an idea as to what's
going on here?
Thanks much in advance for your help,
