Setup Issues NRDS

[mbowden]

I am having issues with the NRDS Config Manager setup. I finally got the components on the server to function correctly I think. However when I go to the client and run the commands specified to retireve the appropriate plug-ins from the server I recieve the following error on the client
"Updated config to version 0.1 Error plugin /usr/local/nagios/libexec/check_ping could not be retrieved from the NRDP server"

My suspicion is that I have to tell the server to allow connections from the clients to retrieve the plugins somewhere in a config file. Not sure which one.

Firewall is off
I can telnet from the server to itself on 5666 and get a connection
I can telnet from the client and get a connection on 5666

the path /usr/local/nagios/libexec/ exists on the server and the fiels exist there.

Logs don't seem to show anything

The client will make the connection via http or https to the address in the config.

If you run the following from the client you will see where the connection is made

Code: Select all

cat /usr/local/nrdp/clients/nrds/nrds.cfg |grep URL=

You should be able to take that http address in a curl request on the client and get some return

Code: Select all

curl http://<your_server>/nrdp/

What OS is your client?

What architecture?

[mbowden]

The curl returns
[root@prod-bnrbat clients]# curl http://<nagios server IP>/nrdp/

*******

The server log entry
<nagios server IP> - - [04/May/2012:08:26:00 -0400] "GET /nrdp/ HTTP/1.1" 200 1243 "-" "curl/7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5"

The client is RHEL5/64

[scottwilkerson]

We need to check some permissions on the client. Lets run

Code: Select all

ls -ld /usr/local/nagios/libexec

and report the output.

If it says the directory doesn't exist, this may be the problem, in that case run

Code: Select all

mkdir /usr/local/nagios/libexec
chown nagios:nagios /usr/local/nagios/libexec

[mbowden]

That seems ok

[root@prod-bnrbat clients]# ls -ld /usr/local/nagios/libexec
drwxr-xr-x 2 nagios nagios 4096 May 3 15:44 /usr/local/nagios/libexec

[scottwilkerson]

Ok, one more on the server

Code: Select all

ls -l /usr/local/nrdp/plugins/Linux/x86_64/check_ping

[mbowden]

-rw-r--r-- 1 nagios nagios 99658 May 3 14:49 /usr/local/nrdp/plugins/Linux/x86_64/check_ping

[scottwilkerson]

This is odd, can I have you run

Code: Select all

/usr/local/nrdp/clients/nrds/nrds_updater.sh -f

[mbowden]

[root@prod-bnrbat clients]# /usr/local/nrdp/clients/nrds/nrds_updater.sh -f

[scottwilkerson]

On the server please run

Code: Select all

cat /etc/group|grep nagios
