General :: Nagios User Permissions To View Any Information Of The Services Requested?
Sep 20, 2010
After Days of trying to install Nagios, I eventually got everything working fine ! The only problem now is I get the following error message on the nagios web interface: "It appears as though you do not have permission to view information for any of the services you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file."

How would you make NIS user information override local user information on client systems? This is what I think is right? Add nis on the passwd registration file on the second line Is this correct?

checking of services in Nagios. You all know the check_[service] command right? In the commands.cfg and windows.cfg. To check for the different types of services/ports, we just replace the [service] in check_[service] with the name of the port? I only know of check_http, check_ssh, check_ftp etc. Some ports like Finger, snmp etc, all these we also write it as 'check_finger', 'check_snmp'? 2) And, if that is the case, do we have to install additional plugins to monitor the ports defined earlier? 3) Lastly, if i want to monitor finger,snmp in windows server, would i need to download any software?

I have installed nagios in a CentOS vm and now its monitoring the local host, one remote host which is also a vm with CentOS 5.3 and one windows xp system. Is there any option for me to change the threshold time for the services given? For e.g. I had a service of current_load which comes as a default plugin while installing nagios itself. What should I do to change the threshold value of the current_load so that I might get the warning or error alert some time earlier as it was now.

My question is about checking remote services under Nagios. I have installed nrpe and the standard plugins on my Nagios server (RHEL 5.4) and the systems I want to monitor. I have been able to create hostgroups. I am somewhat confused as to how to add a new service. I want to check to see if tomcat is running on the remote servers. I found a plugin check_procs. If I run the following command on one of the remotes it works.
Quote:
check_procs -u tomcat6
PROCS OK: 1 process with UID = 101 (tomcat6)[code].....
It doesn't work. I'm not sure how to format the service.I've found gobs of documentation on how to setup and install Nagios, done. I've not been so lucky on how to setup a new service.

Since a week or 2 Nagios is constantly marking hosts (servers mainly but also a few Serial-over-IP converters) down for anything up to a few minutes. Typically, all services stay in OK status. Looking closer at a host in such state, it's status information is
CRITICAL - Packet Filtered (<IP address of host in question>)
in soft state. Sometimes services are in critical state with the host in OK status. Almost always the status information is "No route to host". Further checking shows no problems. Rarely this state lasts longer than one check interval. This started after a link was down, putting, correctly, all hosts and services on red for being unreachable. The link problems were solved within a few hours but Nagios only showed this after 2 reboots. Since then the problems has lessened in frequency gradually, from 5 to 10 of the 34 hosts being reported down at any given moment (the same for the 150-ish services monitored) to where I am now, 1 to 5 problem statuses (counting both hosts and services) and the occasional 'all green' screen. A week ago, when the problems were going a week already, Nagios updated from 3.2.0 to 3.2.1. This showed no apparent improvement.
Still, the Host Groups screen is not stable. A read or yellow status initially signified a problem to be looked at, right now it is likely a false alarm to will go away. Whenever the "packet filtered" or "no route to host" is followed up by a ping test, no problems, not even with the slightest delay or packt loss are found.

I believe that I need to disable the host check, I'm checking a public FTP service and ping is disabled on that FTP host. This is resulting in Nagios reporting the host as down, but the service shows as OK.
Is there any way to disable the host check?

Vmware tells me it cannot start services.I believe the issue is tied to permissions because the message indicated the log with the full details was located in /tmp/vmware-root/setup-4772.log but when I go there I receive a message telling me I do not have permission to the directory and there's a lock symbol on the directory from the File Browser utility.What do I need to do to unlock the folder and get vmware working again ?

I have configured Nagios Server and Client on my RHEL 5.4 machines using these links and help html files in tar balls.
url

I have this scenario.
Nagios Server - 192.168.1.200
Nagios Client - 192.168.1.201 (This is the remote-host I am trying to monitor)
I firmly believe I have at least configured it right as this command on Nagios Server does not show any errors.
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
code....

I want the last login information whenever I log in through FTP.
This is possible for normal console and SSH logins by configuring in /etc/login.defs file. But I am not able to view the last login information when FTP is used.

Ubuntu Documentation > Ubuntu 9.04 > Ubuntu Server Guide > Security > User Management states that there is a default minimum password length for Ubuntu:
Say the password is to be modified by the user using passwd. Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)?
This is rather than examining various places that control the policy and interpreting them since the process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

I made USB live and successfully mounted usb. Commands I used are shown below:
sudo fdisk -l
in response to the first command: sdb1 250GB(this is the target)
sudo mkdir /mnt/usbflash
sudo mount -t auto /dev/sdb1 /mnt/usbflash
All done without any problems. However, when I tried to open file /mnt/usbflash, a dialogue jumps out says "do not have permissions neccessary to view the contents of usbflash". I googled it and found out someone solved this with Alt+F2 and type in 'gksu nautilus'. I tried, and it worked!!! However! Not single file of my 200GB files were shown there! How could it be?? I used comman "ls /mnt/usbflash" to check, and it shows correctly the files inside.

I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info
/home/user1 disk usage
/home/user2 directory info
/home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
