Please advise.

I believe this occurs when you downgrade Core to 4.2.4. Are you running core 4.2.4 because of gearman or another bug?

/usr/local/nagios/bin/nagios -V

What version of XI are you running as well?

Posted: **Mon Jan 21, 2019 6:04 pm**

I am running Gearman.

I notice that /usr/local/nagiosxi/etc/htpasswd.users is no longer getting updated.

Last time stamp is Jan 9 which matches the date I upgraded.

Got a work around?

Please advise.

I haven't been able to recreate the issue on a test XI system, running Nagios Core 4.2.4 and ModGearman. So, let's get some more information.

Can you show us the permissions fo the htpasswd.users?

Code: Select all

ls -la /usr/local/nagiosxi/etc/htpasswd.users

Start a running tail on the cmdsubsys.log:

Code: Select all

tail -f /usr/local/nagiosxi/var/cmdsubsys.log

then from the Nagios XI web UI, go to Admin > Manage Users > <your user> > Edit, enter a new password for the user, and click on "Update User". Go back to the terminal, stop the tail (Ctrl + c), copy and paste the output on the forum.

Also, upload the sudoers file on the forum.

Then for kicks... I see that the passwd file updated.

ls -la /usr/local/nagiosxi/etc/htpasswd.users

Just in case this matters - I am using DUO for 2FA.

Please let me know next steps.

Thanks

I just did a DUO test...

Turned off DUO for my user.

ran this:

Code: Select all

watch -n 4 "ls -la /usr/local/nagiosxi/etc/htpasswd.users"

And when I logged in the time stamp changed.

I think that for some reason that page is trying to load something directly in the /nagios/ directory.

Can you run the following and then try to load the page and see what shows up

Code: Select all

tail -f /var/log/httpd/ssl_access_log|grep 401

Posted: **Tue Jan 22, 2019 5:45 pm**

Scott,

Code: Select all

tail -f /var/log/httpd/ssl_access_log | grep 401
131.199.14.41 - - [22/Jan/2019:16:43:34 -0600] "GET /nagios/js/jquery-1.7.1.min.js HTTP/1.1" 401 381

Is this what you expected?

Yep. This looks like collateral damage from having to downgrade Core for mod_gearman.

Attached is a file that can be unzipped and replace /usr/local/nagiosxi/html/includes/components/nagioscore/coreuiproxy.inc.php that should resolve the issue.

Scott,

Thanks !

The file works for me. Am I able to get that file from a Nagios XI 5.4.13 install if I need it again? In case I have to do a new install and add mod_gearman. Or is this a custom fix just for me. Just curious.

Also, I noticed that the file - /usr/local/nagiosxi/etc/htpasswd.users - is still not getting a new time stamp when I login. I even updated an account password in AD, logged in using the LDAP / DUO authentications. Got in okay. The file did not update.

Is that file needed any more? Or is that now unused. Do I need to be concerned.

Thanks

Steve B
