Good Afternoon,
I've installed a trial instance of Nagios XI into our VMWare environment by using the vdk file (with CentOS, etc.). I'm trying to ticker around with NagVis, but it doesn't appear that I have any accounts that I can use to administer the plugin. I've tried using both the nagiosadmin and my own account that I created an installation, but the nagiosadmin account doesn't accept the default password nor the password that it's currently set to. When I use my account, it will allow me in, but doesn't give me access to edit or change anything (which I presume to mean that my account is setup with the "user" role).

Is there anyway I can reset the admin password to NagVis?

Is there another way that I'm can either assign my account as a "manager" or "admin" role in NagVis?

Am I just a noob and am missing something glaringly obvious but I've been working on it too long to notice?!

Thanks for any help!

Look in the /etc/httpd/conf.d/nagvis.conf file to see what htpasswd.users file it's referencing. Change it to the /usr/local/nagiosxi/etc/htpasswd.users file and restart apache.

Code: Select all

service httpd restart

You should be able to log in as nagiosadmin.

That htpasswd file you mentioned is already setup to be the basic auth:

Code: Select all

<shell banner># more nagvis.conf
# NagVis Apache2 sample configuration file
#
# #############################################################################

Alias /nagvis "/usr/local/nagvis/share"

<Directory "/usr/local/nagvis/share">
  Options FollowSymLinks
  AllowOverride None
  Order allow,deny
  Allow from all

  # To enable Nagios basic auth on NagVis use the following options
  # Just uncomment it. Maybe you need to adjust the path to the
  # Auth user file.
  #
  # If you use the NagVis internal auth mechanism based on the web
  # for you won't need this.
  #
  AuthName "NagVis Access"
  AuthType Basic
  AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
  Require valid-user

  # With installed and enabled mod_rewrite there are several redirections
  # available to fix deprecated and/or wrong urls. None of those rules is
  # mandatory to get NagVis working.
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /nagvis

    # Use mod_rewrite for old url redirection even if there are php files which
    # redirect the queries itselfs. In some cases the mod_rewrite redirect
    # is better than the php redirect.
    RewriteCond %{REQUEST_URI} ^/nagvis(/index\.php|/|)(\?.*|)$
    RewriteRule ^(index\.php|)(\?.*|)$ /nagvis/frontend/nagvis-js/$1$2 [R=301,L]
    RewriteCond %{REQUEST_URI} ^/nagvis/config\.php.*$
    RewriteRule ^config\.php(.*) /nagvis/frontend/wui/$1 [R=301,L]

    # Redirect old regular map links
    RewriteCond %{REQUEST_URI} ^/nagvis/frontend/nagvis-js
    RewriteCond %{QUERY_STRING} map=(.*)
    RewriteRule ^(.*)$ /nagvis/frontend/nagvis-js/index.php?mod=Map&act=view&show=%1 [R=301,L]

    # Redirect old wui map links
    RewriteCond %{REQUEST_URI} ^/nagvis/frontend/wui
    RewriteCond %{QUERY_STRING} map=(.*)
    RewriteRule ^(.*)$ /nagvis/frontend/wui/index.php?mod=Map&act=edit&show=%1 [R=301,L]

    # Redirect old rotation calls
    RewriteCond %{REQUEST_URI} ^/nagvis/frontend/nagvis-js
    RewriteCond %{QUERY_STRING} !mod
    RewriteCond %{QUERY_STRING} rotation=(.*)
    RewriteRule ^(.*)$ /nagvis/frontend/nagvis-js/index.php?mod=Rotation&act=view&show=%1 [R=301,L]
  </IfModule>
</Directory>

My user account is in that file. The permissions on the htpasswd file are:

Code: Select all

-rw-r--r--.  1 nagios apache   91 Apr 23 20:28 htpasswd.users

Should Apache be setup with a different authentication method other than basic?

I can log into Nagios XI with nagiosadmin, but NagVis continues to not allow login with the same password.

Your "nagvis.conf" file and the permissions on the htpasswd look fine. I'm not sure why you cannot log in. This is strange.

Try typing in your browser:

Code: Select all

http://<ip_address>/nagvis

and enter:

Code: Select all

username: nagiosadmin
password: <your_password>

See if you have anything interesting in the apache log that can give us some clues:

Code: Select all

tail /var/log/httpd/error_log

Well, I tried again but to no avail. This might help:

Code: Select all

[Mon Apr 23 21:07:27 2012] [error] [client <my computer>] user iboje: authentication failure for "/nagvis/": Password Mismatch, referer: http://<server>/nagiosxi/index.php?

[Tue Apr 24 04:31:04 2012] [error] [client <my computer>] File does not exist: /var/www/html/favicon.ico

So it does appear to be a wrong password for nagvis. Is there a way to reset the password for the admin account?

I changed the password for the nagiosadmin account from XI and that didn't work. I also set my account up as an admin, and that hasn't allowed me access either.

Well, worse comes to worse, I'm about 1 hour away from seeing if I can use some software to crack the .ht file and see what the password is while continuing to search for a solution.

Can you log into the core interface (which should use the same htpasswd.users) file?
http://<server>/nagios/

Posted: **Tue Apr 24, 2012 9:56 am**

Ah, interesting idea. Here's what I've found:

1) http://<server>/nagios/ - I cannot log into this site using any of the defaults, old, or current passwords.

2) I'm still able to log into Nagios XI home page, but when I try to go into the Core Configure page, it only accepts the old password, not the current password.

3) NagVis is just like #1 above, still won't allow me in as anything greater than a user with my account, but won't login with the nagiosadmin account.

Ideas?

Ok, found this out on the web (take with grain of salt, it's from 2008 and I'm not an Apache htaccess guy): http://www.cyberciti.biz/faq/apache-htaccess/

Basically, it looks like unless it's set to ALL, then the files won't be used. If I run the following:

[root@<server> /]# grep -r -i AllowOverride /etc
/etc/httpd/conf.d/nagiosql.conf: AllowOverride None
/etc/httpd/conf.d/nagios.conf: AllowOverride None
/etc/httpd/conf.d/nagios.conf: AllowOverride None
/etc/httpd/conf.d/nrdp.conf: AllowOverride None
/etc/httpd/conf.d/nagvis.conf: AllowOverride None
/etc/httpd/conf.d/nagiosxi.conf: AllowOverride None
/etc/httpd/conf/httpd.conf: AllowOverride None
/etc/httpd/conf/httpd.conf:# AllowOverride controls what directives may be placed in .htaccess files.
/etc/httpd/conf/httpd.conf: AllowOverride None
/etc/httpd/conf/httpd.conf:# AllowOverride FileInfo AuthConfig Limit
/etc/httpd/conf/httpd.conf:# for additional configuration directives. See also the AllowOverride
/etc/httpd/conf/httpd.conf: AllowOverride None
/etc/httpd/conf/httpd.conf: AllowOverride None
/etc/httpd/conf/httpd.conf: AllowOverride None

Like I said, I'm not a huge htaccess guy, so I'm not sure if changing anything to ALL would create holes to change these files or not, but I thought I'd throw this out there.

From the Nagios XI web interface, go to: Admin->Users->Manage Users->nagiosadmin->Edit, enter a new password and click on "Update User". Give it a few minutes and see if you are going to be able to log into the Nagios Core and Nagvis.
