Hello Oliver,

indeed, it is working.... I didn´t remember, that I used the force_snmpv2 
option  for some networks.....


Thanks!

Jim has already replied with the workaround.

However I thought that we already patched this issue in commit 
c615ba4df2848ff4be5cdb30585fe7017f80d85d from the thread you mentioned. 
Netdisco should try the known community settings, then when they fail it will 
try all possible configurations from SNMP version 3 down to 1 (in that order). 
This means your new SNMPv3 configuration should be found and used. Please let 
me know if you think this isn't the case, as we may have a regression.

regards,
oliver.

Is anyone willing to share their netdisco systemd files?

Here's mine:

[guru# cat /etc/system/system/netdisco-web.service
[Unit]
Description=Netdisco Device Management Application
AssertFileIsExecutable=/home/netdisco/bin/netdisco-web
After=syslog.target network-online.target

[Service]
Type=simple
Environment=PATH=/opt/local/bin
ExecStart=/home/netdisco/bin/netdisco-web start
ExecStop=/home/netdisco/bin/netdisco-web stop
User=netdisco

[Install]
WantedBy=multi-user.target
guru#

Regrettably, it doesn't work.  I see the following in syslog:

May 11 10:44:40 guru netdisco-web: config watcher: watching 
/home/netdisco/environments for updates.
May 11 10:44:40 guru netdisco-web: config watcher: sending TERM to the server 
(pid:14791)...
May 11 10:44:41 guru netdisco-web: Netdisco Web                               
#033[32m[Stopped]#033[0m


Starting by hand works just fine:
guru> /home/netdisco/bin/netdisco-web start
Netdisco Web                                                  [Started]
config watcher: watching /home/netdisco/environments for updates.

guru> which perl
/opt/local/bin/perl

I work for a large organization. They have a large network. They are taking 
over the networks of some smaller organizations and trying to integrate them 
into our network. During the process some networks are only partially connected 
to our main network. Firewalls, routing rules and overlapping NAT IP ranges 
stop our Netdisco server from collecting information from these remote networks.

Some of our monitoring tools allow us to have more than one server acting as a 
collector of information. We can then log onto one website and access the 
information gathered by the various collectors.
Some of these collectors are placed in these unconnected networks. This allows 
us to monitor these other partially consolidated networks.

Is it possible to do something similar with Netdisco? Can an instance of 
Netdisco at one location send its data to an instance of Netdisco at another 
location? I have heard that Postgres can replicate or sync two databases to 
some extent. Is there a way to use this feature to sync different Netdisco 
servers in different locations if they can communicate with each other?

Just curious really. Unless it is very simple, by the time I could implement 
it, the networks would probably be consolidated.

Thanks for all the hard work. It is a great product.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
