NCPA Installtion on Centos7

Hi Team,
We are trying to install the NCPA agent on centos 7 server, however we find that the service is in running state but i also see it s been failed.
Attaching snap FYR.
Our Linux SME has also said that from the ncpa logs , below is the observation, logs snap is attached
The ncpa listener service is not able to start properly as its dependent on the package and the below logs indicate the same.
Without having GLIBC_2.28 it appears ncpa listener won’t start, Kindly check with the Nagios support on how to proceed further as the SOP doesn’t cover this part.
We also want to highlight that GLIBC in turn might be dependent on some other packages for which proper set of instructions are required to fix it at the earliest
CentOS - 7
Nagios version 5.8.3

Hi Sneha,
How are you doing?
Please run the below commands and post all outputs to this ticket:
Code: Select all
cat /etc/centos-release
rpm -qa | grep glibc
ls -l /lib64/libc.so.6
ls -l /lib64/libc*
Best Regards,
Vinh

Re: NCPA Installtion on Centos7
Posted: Thu Jun 24, 2021 3:59 pm

Hi Sneha,
Hope you are having a good day!!
May I ask, how (what command) used to install the NCPA agent?
I looked at my CentOS 7.8 and also CentOS 7.9, both have the following "glic" RPM packages installed:
glibc-common-2.17-307.el7.1.x86_64
glibc-2.17-307.el7.1.x86_64
glibc-devel-2.17-307.el7.1.x86_64
glibc-headers-2.17-307.el7.1.x86_64
Let remove the NCPA package and try the install again.
Please run the following commands to re-install the NCPA agent again:
Code: Select all
rpm -Uvh http://repo.nagios.com/nagios/7/nagios-repo-7-4.el7.noarch.rpm
yum install glibc-devel glibc-headers ncpa -y
Configuring NCPA:
Code: Select all
sudo vi /usr/local/ncpa/etc/ncpa.cfg
Find the following line:
community_string = mytoken
Change it to your required token, for example:
community_string = Str0ngT0k3n
Restart NCPA service:
Code: Select all
systemctl restart ncpa_listener.service
Configure Firewall - Linux
Code: Select all
firewall-cmd --zone=public --add-port=5693/tcp
firewall-cmd --zone=public --add-port=5693/tcp --permanent
Test NCPA:
Please replace "x.x.x.x" with the "NCPA IP Address"
Here's the NAPA installation Instruction:

Hi Sneha,
Hope you are having a good day!!
Were there any changes to your OS lately?
Was ncpa working before? .... or this is a new ncpa install?
I don't think it is a good idea to install "GLIBC_2.28".
What version of "ldd" do you have?
I checked my and it is:
Code: Select all
[root@vt-nagiosxi-62 mrtg]# ldd --version
ldd (GNU libc) 2.17

Also, what outputs do you get for the command below:
Code: Select all
strings /lib64/ld-2.17.so | grep GLIBC
BTW, how did you install "NCPA" on your system anyway?
rpm -qa | grep -i ncpa
Best Regards,
Vinh

here is the response:
Were there any changes to your OS lately? - no
its a new installation.
[root@gmslybf5backup ~]# rpm -qa | grep glibc
glibc-2.17-307.el7.1.x86_64
glibc-common-2.17-307.el7.1.x86_64
ldd --version --> where do i check this on the NAgiosXI machine or the centos box.
NCPA was installed using rpm file, by downloading it to /tmp n then installting.

Hi,
Please run on the NCPA agent, since that's where your "ncpa_listener" failed to start up.
Please run the below commands on the
NCPA agent, as "root" user:
Code: Select all
ldd --version
rpm -qa | grep glibc
rpm -qa | grep ncpa
Also, please run this on NCPA agent as well:
Also, on the NCPA agent, please run:
Code: Select all
systemctl restart ncpa_listener
systemctl status ncpa_listerner
tail -n30 /usr/local/ncpa/var/log/ncpa_listener.log
Please also upload "/usr/local/ncpa/etc/ncpa.cfg" file to this ticket.
