Nagios itself does not prompt for authentication. You must have
configured your Apache server to do it. You'll need to complete that
process. Take a look at your Apache configuration, and any files you
have specified there that it should use for authentication.

[Nagios-users] Need help

2007-03-25 Thread Mukta Sharma 
Hi
This is Mukta Sharma. I am masters student in GWU. I am doing Nagios 
installation and configuration during my Unix project.

I am having one problem, after installing it. I followed all the steps written 
in the documentation to install Nagios. But after restarting my web server when 
i just want to verify if that changes working or not or i want to see the 
Nagios web interface, i entered the  following  path in to my web browser  
http://localhost/nagios/ . It asked me for the user name and password for 
Nagios Access at http://localhost.  i have not entered any password, i just 
created the user as written in the documentation.

So please anyone can tell me what i should do to resolve this problem.

Thanks

[Nagios-users] is there a way to set host min_check_attempt?

2007-03-25 Thread Dinçer Kavraal 

Hi, (as to be numbers are only sample)
We know that host assumed to be DOWN if host does not reply (or timeout) for
5 times successively (I mean 5 distinct checks in order).
Do you know how to make nagios assume that host is UP only and only if host
says OK to ping check for 5 times successively after a HARD-DOWN status?




2007/3/25, Andy Shellam <[EMAIL PROTECTED]>:


Also, in your check_ping command definition, you're requesting the host
respond within 30ms to be classed as up and OK.

This seems awfully quick - personally I request 1000ms (1 second) to
give it a fair amount of time to respond.  If the host/router/whatever
is busy, it could take slightly longer than 30ms to reply, causing a
warning (or longer than 60ms to be 'down'.)

Andy.

Re: [Nagios-users] NRPE 2.7.1 command_prefix problem

2007-03-25 Thread Andy Shellam 
I've been looking at this some more today, and finally found the problem 
and solution!

I added "> /dev/stdout 2>&1" to the end of a command in my nrpe.cfg, and 
got the following result when running check_nrpe off my Nagios server:

"sudo: sorry, you must have a tty to run sudo."

Looking at the /etc/sudoers file on the machine reveals a line "Defaults 
requiretty".  Commenting this out sorted the problem.
For some reason, on a stock FC4 install, the sudoers file was virtually 
empty, yet in FC6 it was full of various settings!

Re: [Nagios-users] Checking host up without ping

2007-03-25 Thread Andy Shellam 
It's probably a bit late for this, but one of my servers used to be with 
a host that blocked pings, so I used check_ssh instead - if the SSH 
service responded, the server was up :)
