NetXMS Forum

Awesome, thank you very much!

Hello,

Just checking in to see if this has been patched yet. I looked at the last couple patch releases but did not see a specific reference for SSH issues (did not know if maybe its referenced as something else in the patch notes).

Great, thank you for the info.

As far as disabling the ssh.nsm local agent, that would be by removing that line 'SubAgent = ssh.nsm' from /etc/nxagentd.conf correct?

Hello,
I recently updated to v4.1.333, and I am having some issues with some servers and their connection status. I have some servers that are going 'offline' due to them blocking the NetXMS Server. After some diagnostics, it appears that the servers are blocking the conneciton due to the NetXMS server trying to SSH to them. Is there a way to completely disable the SSH polling/connectivity check in the entire NetXMS environment, so that NetXMS will stop trying to SSH to the servers?

Hi Filipp,

I have attached the XML that is created when exporting the Dashboard. As for the log, I am not able to find that folder on the Windows Server where the NetXMS Server Application is installed.

There are some log files in C:\NetXMS\log\ though.

I see the following in the above directory:

• netxmsd.log
• nxagentd.log
• nxreportd.log
• commons-daemon.YYYY-MM-DD.log (multiple logs)
• nxreportd.log.YYYY-MM-DD (a few of these)

I looked in them, and did not notice any entries referring to any 'errors'.

Looks like I may have spoke too soon. As of today, the dashboard has stopped auto refreshing again.

Hi Victor,

I just updated to the latest v4.0.2092 Server (4.0.2088 Web GUI), and thus far, the dashboard appears to be functioning as expected. It is automatically refreshing, and thus far has been good for the last 45 minutes.

Here is the XML export of the Dashboard:

<dashboard>
	<name>Company_Network_Status</name>
	<columns>1</columns>
	<options>0</options>
	<elements>
		<dashboardElement>
			<type>20</type>
<layout>
   <horizontalSpan>1</horizontalSpan>
   <verticalSpan>1</verticalSpan>
   <grabVerticalSpace>true</grabVerticalSpace>
   <heightHint>-1</heightHint>
</layout>
<element>
   <objectId>3171</objectId>
   <title></title>
   <severityFilter>126</severityFilter>
   <hideObjectsInMaintenance>false</hideObjectsInMaintenance>
   <groupObjects>true</groupObjects>
   <showTextFilter>false</showTextFilter>
   <showRadial>false</showRadial>
   <fitToScreen>true</fitToScreen>
</element>
		</dashboardElement>
	</elements>
	<objectMap>
		<object id="3171" class="5">Monitor</object>
	</objectMap>
	<dciMap>
	</dciMap>
</dashboard>

When I am logged in via the Admin Account on the Web GUI, I do not experience any issues with the Dashboard updating automatically. However, a co-worker using the Dashboard in URL does not have the Dashboard Refresh. I also have an LG TV (using the LG Web Browser) loading the same URL and it also does not auto refresh.

Edit: Just to add additional information, I am currently using v3.9.420 x64 on Windows OS.

I have a separate question, regarding the Dashboard loaded via Auto Login using the URL.

As noted here: https://wiki.netxms.org/wiki/Autologin_for_Management_Console

Is there a way to make the loaded URL auto refresh so that any changes automatically will display?

Right now I am working on a Network Status Dashboard that displays when Nodes are 'Down'. However, when loading via the Auto URL, the page does not refresh/reflect changes since its first load into the Dashboard.

Thank you.

Awesome, thank you for the explanation. I will work on setting up a user, following your explanation.

Edit:
That worked! Thank you very much. I was missing the step to give 'read' permissions to the nodes themselves.

Hello,

I have found some documentation, and links that refer to loading directly into a dahsboard via a preconfigured URL. What I have been having issues with, is correctly configuring a 'Guest' read-only type user account to accomplish this.

Is there a way to create a user that ONLY can load the Dashboard configured in the URL and not access anything else in the system/management interface? I want to be able to give out the URL with essentially a 'Guest' account that only lets whoever has the URL, load just the Dashboard I want them to see and that is it. I do not want them to be able to interact with it or anything, just essentially 'see' the dashboard.

If this is possible, would anyone be able to provide the appropriate user permissions that the account would need?

Thank you

Hi Victor,

Just to provide a bit more info as far as my config goes. I did go in and actually manually change the IP Subnet directly in the database (while the system was powered down). This did seem to work for a short time, but then it auto changed back to /29.

Hi Victor,

On the Windows Server hosting my NetXMS install, the ipconfig /all reports back just the expected information.

Is the agent part of the server install package? I see a NetXMS Agent service running, but I did not install one of the separate agent packages available on the downloads page. All that is installed, is what came with the Server Install Package.

ipconfig /all output -

Ethernet adapter Ethernet0:

• MAC Address: 00-50-56-B5-0D-B0
• DHCP Enabled: No
• Autoconfiguration Enabled: Yes
• IPv4 Address: 100.100.110.100(Preferred)
• Subnet Mask: 255.255.255.0
• Default Gateway: 100.100.110.1
• DNS Servers: 100.100.110.250
                          10.80.1.250
• NetBIOS over Tcpip: Enabled

I did attempt to shut down the NetXMS application, and go in and change the Mask to /24 from /29 directly in the database. It appeared to fix it for a short time, and then it changed it back to /29. I also have this alert showing for the Server in question: Invalid network mask /29 on interface "Ethernet0", should be /24

Edit:
I tried running that agent command and it looks like maybe I somehow installed the agent with the server install package.

Here is the output for the command:
c:\NetXMS\bin>nxget -l 127.0.0.1 Net.InterfaceList
12 100.100.110.100/24 6(1500) 005056B50DB0 Ethernet0
1 ::1/128 24(2147483647) 000000000000 Loopback Pseudo-Interface 1
1 127.0.0.1/8 24(2147483647) 000000000000 Loopback Pseudo-Interface 1

Great, thank you Victor!

I have the exact same issue. And as the first poster stated, it is not a device out on the network being detected. It is the server NetXMS is installed on itself that is being detected incorrectly.

Also, under the 'Infrastructure Services' section, where the NetXMS server is listed. The Ethernet Interface shows the incorrect /29 subnet as well.

Hello,

For the life of me, I cannot find how to restart the netxms application, to apply changes made in the Server Configuration (ones which note a Yes for restart required).

What is the correct way to restart the netxms application running on Windows Server (without having to actually reboot the windows server itself)?

Alright, so I got the server to start finding all the subnets. I had to change my active discovery subnets from the  /16 subnet, to two /24 subnets. I guess a /16 is just too large an address space for the server to search through in a timely fashion (especially since most of the subnet space it was looking at, was non-existent).

The only issue that is left is that not a single node that it discovers, does it discover it with the proper subnet. It is finding everything as a /32 instead of /24...so right now what I have to do is go in and stop the server, manually change the subnets in the database, then start the server back up. At this point all the hidden nodes start showing up and going in their correct groups.

Alright, so I jumped the gun on the discovery working correctly. ActiveDiscoveryInterval is set at 7200 (default) and it has been approx. 24 hours since I did a clean re-install of everything.

We have multiple subnets.

Subnet A: Found Everything as expected
Subnet B: Found Everything as expected
Subnet Found Everything as expected
Subnet X+: Nothing being discovered

Example:

Total of 40 subnets in the Active Discovery Section on the Network Discovery Configuration Page.
For the Address Filters I have Automatically Generated script with following rules: Accept node if it is within given range or subnet.

I am not using any subnets in the filter section, I am only using address ranges. I am doing this because for some reason nodes were being discovered with a 32 netmask when they should be 24, and this would cause them not to be placed in the Tree on the left (under Entire Network).

*Below subnets are not actual subnets, but correctly depict format.

Address Filter Range Example:

• 10.10.10.1 - 10.10.10.99
• 10.10.10.150 - 10.10.10.254
• 10.10.11.1 - 10.10.11.254
• 10.10.XX.1 - 10.10.XX.254 (XX ranges from 12 to 30)

Active Discovery Target List:

• 10.10.10.0/24 - Discovered
• 10.10.11.0/24 - Discovered
• 10.10.12.0/24 - Discovered
• 10.10.13.0/24 - Discovered
• 10.10.14.0/24 - Discovered
• 10.10.15.0/24 - Discovered
• 10.10.16.0/24 - Discovered
• 10.10.17.0/24 - Discovered
• 10.10.18.0/24 - Discovered
• 10.10.19.0/24 - Discovered
• 10.10.20.0/24 - Discovered
• 10.10.21.0/24 - Discovered
• 10.10.22.0/24 - Discovered
• 10.10.23.0/24 - Discovered
• 10.10.24.0/24 - Discovered
• 10.10.25.0/24 - Discovered
• 10.10.26.0/24 - Discovered
• 10.10.27.0/24 - Discovered
• 10.10.28.0/24 - Discovered
• 10.10.29.0/24 - Discovered
• 10.10.30.0/24 - Discovered
• 10.11.0.0/16
  • 10.11.10.0/24 - Discovered
  • 10.11.20.0/24 - Discovered
• 10.XX.0.0/16 (XX goes from 12 to 30)
  • 10.XX.10.0/24 - Not Discovered
  • 10.XX.20.0/24 - Not Discovered

Alright,

So it does look like the clean re-install has fixed the multiple subnet issue, to a degree.

Now, I am seeing multiple subnets showing up in the 'Entire Network' tree.

I also have 'E-mail Alerts' set up for any node down/up events. And, I am getting Down/Up events/e-mails, for some subnets that are not showing up in the tree on the left at all (but they are in the database). Any idea on what could be causing that?

Also, in the database, these missing IPs have a netmask of 32. When it should be 24 (also my discovery auto filter is set for each subnet as such AAA.BBB.CCC.0/24 or AAA.BBB.0.0/16).

Well I completely deleted the database and uninstalled NetXMS.

I then re-installed a fresh copy and re-configured all the Network Discovery Settings.

How do I restart the NetXMS server correctly? It is running on a Windows Server. Do I just reboot the Windows Server or is there a command I can run from the Windows Server command line to restart the NetXMS server?
