Re: [Nagios-users] monitor windows remote desktop from linux
Yeah, I understand what you mean. The problem is that before
you can monitor, you have to identify what exactly needs to
be monitored. And that's where the troubleshooting comes in.
I disagree. The OP would like to monitor remote desktop logins. As an
admin, I care that RDP is broken, not (neccersarilly) that the clock is
out of sync.
From then on, it could be anything from an authentication
issue to a protocol issue to an encryption issue, clock skew
(I'm not sure if the encryption in RDP is time-sensitive. I
don't think it is, but wanted to mention it), and the
monitoring needs to reflect the specific problem you are
monitoring for.
If you don't know what exactly is going wrong, there is a
high likelihood that you are monitoring the wrong thing and
don't actually detect when the users are experiencing a
problem - just as you saw with the sockets.
An ideal check would be for some meatware to sit infront of a computer,
log in with a few user names, check that the login is succesful, and
push a button which sets the nagios state to green. If they have a
problem, push a different button to set the light to red.
You may be able to get a perl module that can control remote desktop,
have a system log in, run a command, and log out. A quick google doesn't
show anything up, and experimentation with rdesktop -u USER -d DOMAIN
-p PASS -s SOMETHING.EXE $HOSTADDRESS$ seems to leave the session
logged in. You could create SOMETHING.EXE which made a call back to
nagios to say I'm working, but you'd need to get windows to log out
afterwards. A bit of windows scripting would probably do that for you,
so you would have something like
nagiosside
$ok = 0;
$port = 2345;
while ($ok == 0) {
$port++;
$ok = listenOnPort($port)
}
run_in_foreground(rdesktop -u USER -d DOMAIN -p PASS -s
remote_check.wsh $nagiosaddress $port $HOSTADDRESS$);
my ($status, $info) = receivedMsg();
print $info;
exit $status;
windowsside
my ($nagiosaddress, $port) = shift;
open_socket($nagiosaddress:$port);
print_socket(OK,Remote Desktop OK for user $USER);
close_socket();
logout();
For already-written plugins, check_x224 will give a better check than
check_tcp.

[Nagios-users] About Nagios3 and arbitrary code execution
Hi all! At the moment I am using Nagios 3.0.6 (12/01/2008) compiled from the source code provided from nagios.org. Recently I have read in the DSA-1825-1 [1] about an arbitrary code execution. According to I see in changelog of the version 3.1.1, it incorporates a security fix for statuswml.cgi where arbitrary shell injection was possible. Somebody could confirm to me that this vulnerability is the same that is mentioned in the DSA? Thanks in advance.

[Nagios-users] monitoring unreachable hosts
This topic of unreachable hosts that's come up recently has got me thinking about an issue we have. We have a few hosts that are behind proxies and as such are impossible to ping. They have a single service which we can check through the proxy successfully. I'm a little stuck on what to do with the host checks. I can supress the alerts, but they still always show as critical (kind of permanently critical). Maybe I'm too anal, but I don't like that. It's meaningless. So I was thinking of making the host check command identical to the service check command. The end result being that if the service is up, the host will also show up, if the service is down, the host will also show down. Still weird, but at least kind of conceptually correct. What concerns me about is the my understanding of how host and service checks would work in this case. If the service check fails, it's going to want to fallback and try the host check which will fail also because it's running the exact same check as the service. However, what if I've disabled notfications on the host itself? That is, I really only ever want service alerts -- no host alerts. In the case of a normal set of host/service checks, Nagios will notice that the host is down, suppress alerts about all the services being down and send out only a host is down alert. In the scenario where the host and service checks are the same and the host notifications are disabled, wouldn't a service alert be suppressed and I'd never hear about an issue on this host? Again, conceptually, the service result is all that's meaningful. Maybe Nagios is smarter than that and would decide that since the host notifications were disabled that it would go ahead and send the service alerts anyway? I guess this could be an issue with any host that has notifications disabled now that I think about it. I tried earlier to disable all checking of the host in this case and that gives me a host unreachable alert when the service goes down. That makes sense since the host can't be checked, but I don't want it going into that bogus state. What would probably be ideal is if Nagios had some way of marking a host as being irrelevanet. That is, the service would sort of stand alone without any host dependency in terms of monitoring. Kind of strange, though.

[Nagios-users] Organisation of hostgroups availability reports
Hi all, I'm looking for the most flexible way to create availability reports of host or service groups. Let's look at the availability of servers for example and take following conditions into account: * Hosts can be of different types: 4 possibilities (Servers, Network equipment, Storage, Peripherals) * Hosts can be located in different countries: 15 possibilities. * Servers can be located in different environments: 2 possibilities (Remote offices, Datacenters) * Servers can have different OS's: 5 possibilities (Windows, Linux, Solaris, Aix, Novel) * Servers can have a different state: 3 possibilities (Production,Acceptance, Development) I want to have the ability to create reports with any kind of combination of the abovementioned parameters. For example: Give me a report of the Belgian Datacenter Windows Development Servers It would be great to have a functionality within Nagios saying: only show hosts that appear in each selected group. But that's not the case. So, ... Any idea how to organize hosts and how to get this kind of information out of there?

[Nagios-users] Multiple contactgroups for a host through groups or templates
Hi all,
I'm seeking a way to be able to associate a contactgroup with a server, in
addition to the contactgroups that are already associated with the server
through a hosttemplate, such that if the host goes down, both contactgroups
are notified. As I outlined in a post to this list a couple of days ago,
I've been trying to do it by associating the host with a second hosttemplate
that has the contactgroup associated with it, but only the contactgroup
associated with the first hosttemplate in the list is notified if the host
goes down.
For example:
define host {
host_name doris
use oncall-host,unix-host
register 1
}
define host {
host_name oncall-host
contact_groups oncall-primary
register 0
}
define host {
host_name unix-host
contact_groups +unix-admin
register 0
}
When doris goes down, only the 'oncall-primary' contactgroup is notified,
not 'unix-admin'.
Short of manually associating the contactgroup with the host, can anyone
suggest a way I might achieve my desired configuration using groups or
templates?
Thanks,
Guy.

Everything looks fine, but when I start Nagios and look at View
Config-Object Type-Host Groups, I see this!
Group Name Description Host Members
CACHE_DNS Caching DNS service CDC-Dnscache , CDC-Ns1 , CDC-Ns1auth ,
IDC-Ns2 , IDC-Ns2auth , SDC-Ns3 , SDC-Ns3auth
The CACHE_DNS host group should only contain CDC-Ns1, IDC-Ns2, and
SDC-Ns3. Why are the other hosts in there? I have tried renaming, I have
tried starting fresh with new config files, new retention data, new
object cache. Yet the hostgroup CACHE_DNS still contains hosts I did not
define to be there.
Any help is appreciated, clues, clue bats, links, (yes I looked at the
change log and searched for an answer, no luck).
Thanks,

So I was thinking of making the host check command
identical to the service check command. The end result being that if
the service is up, the host will also show up, if the service is down,
the host will also show down. Still weird, but at least kind of
conceptually correct.
Yes, that's one approach that leads to a somewhat correct indication.
However, what if I've disabled notfications on the host itself?
That is, I really only
ever want service alerts -- no host alerts. In the case of a normal
set
of host/service checks, Nagios will notice that the host is down,
suppress alerts about all the services being down and send out only a
host is down alert.
In the scenario where the host and service checks are the same and the
host notifications are disabled, wouldn't a service alert be
suppressed
and I'd never hear about an issue on this host?
Yes, if you've disabled notifications for the host.
I tried earlier to disable all checking of the host in this case and
that gives me a host unreachable alert when the service goes down.
That
makes sense since the host can't be checked, but I don't want it going
into that bogus state.
To get an unreachable state, a parent for this host would have had to
return a non-OK result. If you don't want that, find out why the
parent returned a non-OK state or remove the parents definition.
What would probably be ideal is if Nagios had some way of marking a
host
as being irrelevanet. That is, the service would sort of stand alone
without any host dependency in terms of monitoring. Kind of strange,
though.
90% of my hosts are like this. No parents, no check_command and
check_period none. Most of what I monitor are routers, that I only
care about pinging. I have a ping service and no checks of the host at
all. Notifications only come for the service.

Re: [Nagios-users] Check result used as an argument for the next check
2009/7/8 Marc-André Doll m...@b-care.net: Is there a way to use the result of a check (the return value or the output for example) as an argument for the next check. I need to keep an history of the checks of one particular service in order to compare the previous check result with the current one. I thought to use the $SERVICESTATEID$ and $SERVICEOUTPUT$ macros but the documentation says that would make no sense because they are not initialized when a check is running. Marc-André Doll I use $SERVICEPERFDATA$ all the time in my service check commands and it works fine, I imagine you can use $SERVICEOUTPUT$ too. It isn't difficult to test, just write a little check command to spit the unixtime stamp and whatever you pass to it back out, and feed it the $SERVICEOUTPUT$ as an arguement. .r' -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Hmmm
OK, well couldn't you just remove the check_command for those hosts?
From the define host docs:
check_command: This directive is used to specify the short name of the
command that should be used to check if the host is up or down.
Typically, this command would try and ping the host to see if it is
alive. ... If you leave this argument blank, the host will not be
actively checked. Thus, Nagios will likely always assume the host is up
(it may show up as being in a PENDING state in the web interface).
This is useful if you are monitoring printers or other devices that are
frequently turned off. ...

Re: [Nagios-users] basic nagios/linux info needed
Hi Natalie, I don't know the answer to Question 1... might be worth googling for. In answer to Question 2, yum is, to quote from the first result of my google search for 'man yum', an interactive, automated update program which can be used for maintaining systems using rpm. Basically, yum is a system that allows an administrator to download and install pre-built software packages from a repository. So, yes, it has installed nagios for you, so you don't have to compile binaries etc. However, it is nagios 2 rather than nagios 3. Cheers, Guy.

Probably not a coincidence that CDC-Ns1auth starts with CDC-Ns1. Sounds like it's using CDC-Ns1 as a prefix to match hostnames, rather than as an actual hostname. Looks like there's config setting in 3.0 called use_regexp_matching which might control that. Perhaps in your old config file that was somehow turned on. (Or perhaps not defined at all, and on is the default.) Who knows what other old settings you're inheriting too. It's probably best for you to scrap your old config, and start fresh with a new 3.0 config file, then adopt it to your needs (i.e., point it to whatever custom definitions/definition-files you've created). As I did, this is an all new install, everything is being re-done after a complete host and service audit of our network. There are no old configs in use. Matching, h, that sticks in my mind somewhere. Time to go read the docs yet again for what I may have missed.

I am at a point that I am looking for gremlins, no other cause can

I am replacing a very old Nagios install with Nagios 3.0.6, no
importing, a fresh install, new hardware, a network audit and entering
all hosts and services manually. It seems that no matter what I do I
keep getting some hosts added to a host group, even though I clearly did
not define them as part of the host group.
My hostgroups.cfg,
###
define hostgroup {
hostgroup_name AUTH_DNS

}
define hostgroup {

###

contact_groups host-oncall
notification_interval 15
notification_period 24x7

}
Everything looks fine, but when I start Nagios and look at View
Config-Object Type-Host Groups, I see this!
Group Name Description Host Members
CACHE_DNS Caching DNS service CDC-Dnscache , CDC-Ns1 ,
CDC-Ns1auth ,
IDC-Ns2 , IDC-Ns2auth , SDC-Ns3 , SDC-Ns3auth
The CACHE_DNS host group should only contain CDC-Ns1, IDC-Ns2, and
SDC-Ns3. Why are the other hosts in there? I have tried renaming, I have
tried starting fresh with new config files, new retention data, new
object cache. Yet the hostgroup CACHE_DNS still contains hosts I did not
define to be there.
Any help is appreciated, clues, clue bats, links, (yes I looked at the
change log and searched for an answer, no luck).
Thanks,
DAve

[Nagios-users] External Command File Error
Hi there - I completed the installation of the Nagios 3.1.2 application onto our CentOS 5.3 server. Everything appears to be working fine with one noticeable exception: If I go to the host information page of any host, and select Schedule a check of all services on the host, and subsequently click on commit, I get the following error: Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update! The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions. An error occurred while attempting to commit your command for processing. I went through and verified the following: 1. The nagios user account has the bash shell. 2. The permissions on the nagios directory, and its subdirectories are as follows: user:group ownership= nagios:nagios permissions = rwxrwxrwx What did I miss here, and what can I do to correct it?

Re: [Nagios-users] External Command File Error
Hi there -- Thanks for your reply. The answers to your questions are the following: Does /usr/local/nagios/var/rw exist? Yes, it does. Does /usr/local/nagios/var/rw/nagios.cmd exist after starting nagios? Yes, it does. The external commands option is set to 1 in the nagios.cfg file. Is the ownership of /usr/local/nagios/var/rw nagios:nagios? Yes, the ownership is set to nagios:nagios. Is the ownership of /usr/local/nagios/var/rw nagios:nagios? If so, review the Fedora Quickstart Guide, specifically Step 1, Create Account Information; you've missed setting the ownership of the files and apache group membership correctly. Apache will need to be restarted after making those changes. I went ahead and ran the usermod command for Apache that was mentioned in step one of the Fedora Quickstart guide. Once that was done, I restarted Apache, and that appears to have solved the problem.

[Nagios-users] Weird issue with check_ping

Re: [Nagios-users] Weird issue with check_ping
I've seen this happen when ping returned an error. In my case, it was actually ping6 because it had a bad IPv6 address configured. Since it's intermittent in your case, most likely the root cause is something else, but ping is still returning an error. If I had to venture a guess, maybe it's destination unreachable - which would indicate a real problem in your network. If 10.1.1.1 is on a different subnet, it would be a routing issue. If it's on the same subnet, it's probably an ARP resolution issue. But all that is guesswork. You'd have to catch ping in the act and see what it really returns. I don't see any options in check_ping that could give you that information, but maybe you can write your own shell script that watches for ping error messages and logs them or reports them as check results.
