NCPA connection issue

Not a VPN, no. I don't believe it's going through our proxy. We do have one, but it should only be used when traversing the internet, which this doesn't need to do.

What is the Nagios XI and NCPA wizard version that you are currently using?

Enable debugging in the ncpa.cfg file by setting this line:

Code: Select all

loglevel = debug

Save, exit and restart ncpa listener.

Run the following command and show the output:

Code: Select all

curl -k 'https://<IP>:5693/testconnect/?token=<TOKEN>' -v

Also, upload the ncpa_listener.log (and win32service_ncpalistener.log if you have one) to the forum.

XI is version 5.6.10, NCPA wizard is version 2.2.3.

Code: Select all

[root@lisl-ngos-02-pv ~]# curl -k 'https://<REDACTED>:5693/testconnect/?token=<REDACTED>' -v
* About to connect() to <REDACTED> port 5693 (#0)
*   Trying <REDACTED>...
* Connection refused
* Failed connect to <REDACTED>:5693; Connection refused
* Closing connection 0
curl: (7) Failed connect to <REDACTED>:5693; Connection refused

We set logging to debug level, but nothing seems to be logging, the file has nothing in it.

What is the output of the command below from the Nagios XI server?

Code: Select all

nmap <ip address> -p 5693

[snapon_admin]

[root@lisl-ngos-02-pv ~]# nmap <IP> -p 5693

Starting Nmap 6.47 ( http://nmap.org ) at 2020-03-10 13:31 CDT
Nmap scan report for <IP>
Host is up (0.00017s latency).
PORT STATE SERVICE
5693/tcp closed unknown

Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds

[Box293]

OK so it's clear from that output that tcp port 5693 to the destination device is closed.

[snapon_admin]

Right, but how would I go about correcting that? As far as I can see we don't have that port blocked over the network as I can browse to the NCPA GUI for that PC in a browser.

Can you try installing the latest version of NCPA (2.2.1) to see if this is going to fix your issue?

If you are still having the same problem, post the ncpa.cfg file on the forum. Please hide/obfuscate sensitive info.
