Dear Team,

I have a nagios xi installed localy and 2 nagios core installed at 2 differents clients site, I followed the instructions from https://assets.nagios.com/downloads/nag ... h-NRDP.pdf, and in 1 client works fine and the other one don't, anyone know we this could happen?

ps: Both clients have open firewall ports and rules configured
ps: I use different tokens for each client

Do you have both tokens listed on your Inbound Transfers page?
Can you verify they both also appear here on the Nagios XI server

Code: Select all

grep authorized_tokens /usr/local/nrdp/server/config.inc.php

Yes, both tokens appers.

follow the output

[root@atbr2mong001pvx ~]# grep authorized_tokens /usr/local/nrdp/server/config.inc.php
$cfg['authorized_tokens'] = array("MbJMjUTeWMEM","MbJMjUTeWMES",);

Are you seeing errors in the nagios.log on the sending server that is having the problem?

paulo.ferreira · Post by **paulo.ferreira** » Wed Apr 01, 2020 8:28 am

Only a few like this one below:
:[1585746819] Warning: OCHP command '/usr/local/nagios/libexec/send_nrdp.php --url=https://10.202.1.69/nrdp/ --token=MbJMjUTeWMES --host="SGS-SANTOS-HP-RACK-SERVIDORES" --state=0 --output="PING OK - Packet loss = 0%, RTA = 13.24 ms"' for host 'SGS-SANTOS-HP-RACK-SERVIDORES' timed out after 0.00 seconds
[1585746819] wproc: Core Worker 15366: job 109889 (pid=9438) timed out. Killing it
[1585746819] wproc: OCHP job 109889 from worker Core Worker 15366 timed out after 70.67s

But this error shows just for a few Devices, and none of them shows at nagios xi.

Ok, it looks like this isn't working, maybe there is a problem reaching the server?

Code: Select all

/usr/local/nagios/libexec/send_nrdp.php --url=https://10.202.1.69/nrdp/ --token=MbJMjUTeWMES --host="SGS-SANTOS-HP-RACK-SERVIDORES" --state=0 --output="PING OK - Packet loss = 0%, RTA = 13.24 ms"

How about the results of this

Code: Select all

curl -vvv -k https://10.202.1.69/nrdp/

And this?

Code: Select all

paulo.ferreira · Post by **paulo.ferreira** » Thu Apr 02, 2020 6:50 am

No return from the script

[root@BRMON001 libexec]# ./send_nrdp.php --url=https://10.202.1.69/nrdp/ --token=MbJMjUTeWMES --host="SGS-SANTOS-HP-RACK-SERVIDORES" --state=0 --output="PING OK - Packet loss = 0%, RTA = 13.24 ms"

If you run that again, and look at the apache log on the remote system (10.202.1.69) are you seeing any errors?

Code: Select all

grep nrdp /var/log/httpd/access_log
tail -50 /var/log/httpd/error_log
