NRDS unable to connnect to NRDP server after upgrade

[skynardo]

This did not work.
[nagios@dsa528 ~]$ /usr/local/nrdp/clients/nrds/nrds.pl -H 'dsa528'
ERROR: could not connect to NRDP server at https://nagiosxi/nrdp/

If I change my nrds.cfg to http, I now get:
[nagios@dsa528 ~]$ /usr/local/nrdp/clients/nrds/nrds.pl -H 'dsa528'
ERROR: The NRDP Server said HTTPS REQUIRED
ERROR: NRDP Server said - HTTPS REQUIRED at /usr/local/nrdp/clients/nrds/nrds_updater.pl line 163, <CONFIG> line 20.

From the client, can you run a nmap against the Nagios XI server and post the result?

[skynardo]

# nmap nagiosxi

Can you post the files from this folder so we can review them?

Code: Select all

/usr/local/nrdp/clients/nrds

[skynardo]

[root@dsa528 nrds]# pwd
/usr/local/nrdp/clients/nrds
[root@dsa528 nrds]# ls -al
total 28
drwxrwxr-x 2 nagios nagios 4096 Feb 10 16:28 .

Can you zip up those 4 files and attach them to this post?

[skynardo]

Here they are.

Can you edit the send_nrdp.sh file and change the following 2 lines from

Code: Select all

rslt=`curl -f --silent -d "$pdata" "$url/"`
rslt=`wget -q -O - --post-data="$pdata" "$url/"`

to

Code: Select all

rslt=`curl -k -f --silent --insecure -d "$pdata" "$url/"`
rslt=`wget --no-check-certificate -q -O - --post-data="$pdata" "$url/"`

Save the file out and see if this fixes it for you.

Can you verify the version if XI you are running?

[skynardo]

Yes, this works around the problem, but I already have been using a work around by changing my nrds.cfg URL from https to http on any new clients that I install. This works fine unless an updated cfg gets pushed out and breaks it again. I am trying to find out what changed to cause this to break for new nrds clients. I am running Nagios XI 5.2.0

[tgriep]

If I remember correctly, that version (5.2.0) , the send_nrdp.sh file was released and it was missing those settings by mistake.
In the newer version of XI, they were added back.
