NRDP client not registering

[reyntjensw]

Hi

I'm trying to deploy a client with NRDP, I've installed the agent on the client which is running Windows 2008 SBS
We see the message below reappearing every time the job runs.

We also have NRDP running on a Windows 2008R2 server, there everything is working fine.

Do you see any errors in the XI server's apache logs? Submit an nrdp check from the remote system, while tailing the apache error log:

Code: Select all

tail -f /var/log/httpd/error_log

Hi Abrist

I've checked all the logs in the /var/log/httpd folder but I cannot find any connections listed in there.
If open a browser on the server and if I browse to the monitoring url, it is showing up in the logs.

The other checks done by nagios are not appearing in the logs as "access" to the apache webserver.

Is anything showing up in Unconfigured Objects? Is the "Enable Listener For Unconfigured Objects" checkbox selected under the "Performance Settings" (Admin->Performance Settings->Subsystem)?

[reyntjensw]

Hi

The server is not showing up in the unconfiguered objects, but when we add a new server, it is showing up. The listener is enabled at this time.

[sreinhardt]

You just mean to say that it shows in the XI interface, not that it is now receiving check results correct? If so, please do the following and post the results:

tail -f /var/log/httpd/error_log | grep nrdp
*attempt to register or send nrdp results*

tail -f /var/log/httpd/access_log | grep nrdp
*attempt to register or send nrdp results*

[reyntjensw]

Hi the error log is not showing anything.
The access log is only showing working NRDP clients.

Do you have any firewalls in place between the two? Are you able to, from the non-working NRDS machine, view the XI interface in a web browser?

[reyntjensw]

Both servers are behind a firewall, when I surf from a non-working NRDS machine to the webinterface of the XI, I'm able to login.
If I past the url that is in the log, I'm getting data back.

The machine is just not registering.

The server is not showing up in the unconfiguered objects, but when we add a new server, it is showing up. The listener is enabled at this time.

Can you elaborate on this? How are you adding the server? Through the CCM manually?

Also, can you run a tcpdump on the Nagios server and then try to manually submit the NRDP results?

Code: Select all

tcpdump host <windows ip> -X -w /tmp/tcpdump.pcap

then send the NRDP result, cancel the tcpdump, and send the /tmp/tcpdump.pcap file.
