Hi
This post is related to
https://support.nagios.com/forum/viewto ... =7&t=55496
I found that after upgrade of the operative system to Ubuntu 18.04, the ndo process dump this error to syslog:
Code: Select all
ndo2db: Error: queue recv error.
ndo2db: message repeated 278 times: [ Error: queue recv error.]
The only solution that I found to resolve this is performing login at the console, but if I perform logoff from this console the error happens again.
Left the console with the user logged is a problem for me because means a security fault
My configuration:
ndo2db.cfg
Code: Select all
ndo2db_user=nagios

Do you know why this happens?
Thanks!

Hello
@pepe_carlos ,
I discussed your issue with another team member, and it's likely there's a libary issue ( when upgrading) and you should try to re-install Nagios Core and then re-compile Ndo.
Also, you have ndo configured to write to a tcp socket, and since the database is local, I would recommend changing this back to the unix socket option.
Finally, make sure the nagios account is not expired.

Hi,
I recompile and reinstalled nagios and ndoutils, and change tcp to unix socket in ndoutils configuration but the result is the same.
The sugested command chage -l nagios return the next:
Code: Select all
Last password change : mar 20, 2013
Password expires : never
Password inactive : never
Account expires : never
Minimum number of days between password change : 0
Maximum number of days between password change : 99999
Number of days of warning before password expires : 7
Thx
Regards

Maybe it is a kernel limit setting that is getting reset at logout.
Can you post the following files here so we can view them?
Code: Select all
/etc/security/limits.conf
/etc/sysctl.conf
Also, run the following commands as root and post the output here so we can view it.
Code: Select all
ps -ef --cols=300
grep nag /etc/group
When the issue happens, is the ndo2db daemon running on the server?

Add this line
to the /etc/sysctl.conf file
Add these entries
Code: Select all
* hard nofile 10000
* soft nofile 10000
root hard nofile 10000
root soft nofile 10000
* hard stack 102400
* hard stack 102400
to the /etc/security/limits.conf file.
Reboot the server for the changes to take effect and see if the Kernel Message queue is processed while not logged in.
If not, look in the /var/log/syslog for any errors that could hold a clue on why the ndo2db processes is not running which I feel is the issue.

I would suspect it is a user account limitation or a entry in the /etc/sudoers file that is requiring a tty to be present for the nagios user.
