I agree. I had asked if anyone that was familiar with SELinux was
interested in submitting a FAQ entry but I don't see any bites.

There are some posts in the archive with various policies but I haven't
used SELinux enough to know what's a good policy.

[Nagios-users] BUG? Segfault & coredump with scheduled downtime, downtime scheduled horked

[karl . kornel]

Dear fellow Nagios users,

        Ever
since downloading my first Nagios tarball (2.0rc2), and continuing to version
2.5, I have been noticing a big problem with downtimes.  It appears
that if there are more than a couple of downtimes scheduled, Nagios will
crash partway through the list.  This is a really big problem, for
several reasons:  I've written a tool that automatically schedules
recurring downtime.  It integrated into the Nagios web site, and anyone
with access to schedule downtime for a host/service can schedule recurring
downtime, and see the other recurring downtimes that have been scheduled
by their fellow contacts.  I want to release it publicly, but I can't
finish testing because of Nagios crashing (several downtimes a day == one
crash per day).  On a different note, this (Nagios) was the first
open-source tool to become widespread in our IT department.  I'd like
Nagios to continue to gain acceptance in our group (most of whom are SAP/Oracle/Windows/etc.),
and this problem doesn't help.

        I
don't want to look like I'm barging in and saying "Fix this!",
so I brought some stuff along with me, and I did what I could to diagnose
the problem.  First of all, I have two core files.  When I installed
Nagios, I used the 'install-unstripped' target, so these core files, and
my copy of Nagios, include debugging symbols.  Here's what the backtrace
looks like from the most recent coredump:

(gdb) bt
#0  0x2b20dd20 in strlen () from /lib/libc.so.6
#1  0x0042866f in hashfunc2 (
    name1=0x44e4f697 ,
    name2=0x4e202c69 ,
    hashslots=1024) at utils.c:4285
#2  0x00437d15 in find_service (
    host_name=0x44e4f697 ,
    svc_desc=0x4e202c69 )
    at ../common/objects.c:5016
#3  0x004518cf in handle_scheduled_downtime
(temp_downtime=0xfe6500)
    at ../common/downtime.c:311
#4  0x0042130e in handle_timed_event
(event=0x722320) at events.c:1289
#5  0x00421893 in event_execution_loop
() at events.c:964
#6  0x0040eeb2 in main (argc=Variable
"argc" is not available.
) at nagios.c:710
(gdb) 

        I tried to look through the code, and
the coredump, and the most I could determine is this:  It looks like
the scheduled downtime event struct was corrupted at some point during
its life in the high-priority event queue (for one thing, between the time
Nagios was started and the time it crashed, no more than 10 downtimes had
ever been scheduled, yet the downtime ID is 81, and no downtime had ever
been scheduled that was 2072 hours long):

(gdb) frame 3
#3  0x004518cf in handle_scheduled_downtime
(temp_downtime=0xfe6500)
    at ../common/downtime.c:311
311              
      svc=find_service(temp_downtime->host_name,temp_downtime->service_description);
(gdb) print *temp_downtime
$1 = {type = 0, host_name = 0x44e4f697 ,
  service_description = 0x4e202c69 , entry_time = 0, start_time = 2334111869775642625,
end_time = 0,
  fixed = 6488400, triggered_by = 0, duration
= 7459712, downtime_id = 81,
  author = 0x2aaa ,
  comment = 0x44e4f6bf , comment_id = 0,
  is_in_effect = 0, start_flex_downtime = 0,
incremented_pending_downtime = 1,
  next = 0x0}
(gdb) 

        So,
I've got two coredumps.  When the second coredump took place, and
before restarting Nagios, I tarballed the entire Nagios directory, including
all log files, cache files, etc..  I don't know if the object cache
or downtimes data files would be of any help, but I've got them in storage.

        So,
what else?  Well, I've looked at the event log for today, and I did
notice something weird:  My recurring downtime scheduler schedules
the day's downtimes every day at midnight, writing commands out to the
Nagios command socket.  The event logs record receiving 6 SCHEDULE_SVC_DOWNTIME
commands, which is correct.  The first downtime started correctly,
and ended correctly.  However (here's the weird part), the other downtimes
started at the exact same moment the first downtime ended.  Even more
weird, the second, third, and fourth downtimes ended when they should have
started.  Here's all of the downtime-related entries from the event
log, with the time values converted into readable dates/times:

Re: [Nagios-users] Apache2 permission denied error

SELinux. I don't have a specific resolution for you, but that should point 
you in the right direction.

Curiously, a search for "selinux" or "forbidden" comes up blank in the 
Nagios FAQ. This is a VERY common configuration error that I see on the 
list at least 3 times a month. Perhaps a relevant FAQ can be crafted?

[Nagios-users] Apache2 permission denied error

[Rusch, Daniel]

All,

 

I read the manual, the archives, googled etc.

 

System:  

 

Apache2 standard Suse 9 enterprise sp3 install

 

We installed nagios 2.5 as per install instructions (BTW I’ve
been using nagios since netsaint days and have installed nagios dozens of
times)



Apache runs as wwwrun

 

When we try to access the web interface we get the following
error:

 

Access forbidden!

You don't have permission to access the requested
object. It is either read-protected or not readable by the server. 

If you think this is a server error, please contact
the webmaster. 

Error 403

Checking the apache log file I see:

 

[Thu Aug 17 16:08:14 2006] [error]
[client 10.30.150.117] (13)Permission denied: file permissions deny server
access: /usr/local/nagios/share/index.html

 

 

The permissions on the share directory are (and all parent directories
too, ownership of parent directories change of course):

 

drwxrwxr-x   9 nagios nagios  360
2006-08-17 09:27 share  

 

permissions on the index.html file:

 

-rw-rw-r--  1 nagios nagios   658
2006-08-17 09:15 index.html

 

 

 

relevant groups:

 

nagios:!:1001:nagios,wwwrun

 

The Alias in apache for the share directory is:

 

Alias /nagios
/usr/local/nagios/share/



    Options None

    AllowOverride AuthConfig

    #AllowOverride None

    Order allow,deny

    Allow from all



 

As can be seen I have tried changing
the AllowOverirde directive to no avail

 

 

Thoughts?

 

Dan

We use webinject here for precisely this reason, and it works well.  It
also supports MRTG format output if you need that.

I had also written a homegrown plugin that parses the web page to pull
out session IDs from URLs and do a bit more magic, but the latest
webinject seems to do everything itself now.

Re: [Nagios-users] Good Linux and Mac Client

[Maxwell,Brady]

SNMP will work on both and NRPE works well for Linux boxes. Not sure
about Macs but since OSX is sitting on a free bsd Kernel (I think). NRPE
might work well on OSX as well. Not sure.
There is also NSCA which I have not had a lot of luck with except when
configuring remote nagios systems to report into a central Nagios Box,
or distributed nagios implementations.

Links to NRPE and NSCA are provided at the Nagios site

Re: [Nagios-users] detect 2 DHCP Servers on network?

[Harkisoon, Sharan W.]

I don't mean to be off topic, but rogue DHCP servers can be easily
avoided using switches that support layer-3 ACL's to block dhcp server
replies from user ports on switches that support it (all new cisco
switches including the 2950's/3550's/37xx's and even smc,dlink,allied
telesyn support this).  A cisco feature called "dhcp snooping" also
prevents rogue dhcp servers.  Food for thought.

   The pitfall here is that if you're running redundant DHCP servers
it's possible to receive two offers.  ISC DHCPD can function in this
way.  A regular client would see the first offer, accept it, and ignore
the second one; the monitoring script would have to be aware of the
network architecture to account for that.

   One thing you could do is record the IP address(es) of your real DHCP
server(s) and if you see anything come in from *anywhere else* raise the
alarm.

After all that and still a net NULL answer? Some kind of pointer would
have been useful to justify the chatter.

They are (sometimes) refered to as agents. Which make it much clearer what
way you want to go.

However these agents are as diverse as the things you want to monitor.

No client exists that I know of nor is there really a need for one.
check_nrpe or check_by_ssh + whatever interesting plugins you want to
run on the remote machine (check_disk, check_proc, check_swap, etc, etc,
etc) is the way to go. I definitely know the plugins compile under linux
and almost certainly compile under OSX.

>   check (ping)?I don't follow either. Some hosts you may only want to set up a service "PING", but you want the host to also be checked so that you get a single HOST failure, vs a service failure if the host is down.
So setup the host with a check_command   check-host-alive line, and then add a service for the same hostdefine service{     use generic-service    host_name  hostname
    service_description Ping    check_command   check-host-aliveIf the service check fails, it will force the hose to do a host check, and since well it's probably down, you should only receive a host critical/unreachable alert.
Sorry if your not really talking this basic, then your going to have to provide a bit more information.You could also force the host to actually be checked like a service by enabling active checks every x minutes (create a new host template)

Re: [Nagios-users] How to get stdout from event handlers into Nagiosemail messages?

[Kelly Alexander]

I was hoping that the event handler ran first, and then the
notice was sent out.  Guess that's not the way it works.

Since it's not possible I won't worry about it anymore and will
just write something that notifies me from the handler itself.

If you think about it, this must be impossible.

Since the event handler is called at the same time as the notifications,
the output (if any) is not avaiable when the notifications are queued as
the event handler has not yet run.

The only way I can see to do this is to code an email sender into your
event handler script.

You could fudge it by creating a dummy service for the same host that
uses freshness to immediately reset to OK and has a count of 1, and then
have your event handler send a passive alert (containing the output
text) to this service.  The dummy service (which has the same contacts
as the main service) then sends out a separate alert to the contacts
with this information.  You could probably even create a generic
eventhandler wrapper script to do this.

I would recommend firefox. Perhaps thunderbird for the alert messages.

But perhaps you think of something completely different as 'client' of
Nagios. But it would be wise to explain how you define a 'client'.

Couldn't you write a script that diffs nmap results and report "0" if
diff doesn't come back with anything and "1" otherwise? nmap could be
cronned to run hourly - or so - and the results diffed with a baseline
file resulting in the code which nagios can cat... or something.

Sorry, not a developer but this seems easy enough for someone who is,

good idea to have this python wrapper to nmap plugin. 

I was actually thinking more of one pass for the whole network alerting
you to what has changed. I think I will write this in bash to start off
with since that's the fastest language to do this kind of stuff in.

I can see how this does fit in very well with the nagios way of doing
things since the macros can be used to automate part of it, but you
still need to specify all the ports that should be open.

I think I may give this a python plugin try when I have some spare
time...

   The pitfall here is that if you're running redundant DHCP servers
it's possible to receive two offers.  ISC DHCPD can function in this
way.  A regular client would see the first offer, accept it, and
ignore the second one; the monitoring script would have to be aware
of the network architecture to account for that.

   One thing you could do is record the IP address(es) of your real
DHCP server(s) and if you see anything come in from *anywhere else*
raise the alarm.
  

that it what I previously mentioned as a good idea to implement, making
sure that the from address matches. This could easily be supplied as a
command line flag.

The other idea regarding the number of offers is also taken into
account, in the same way you should be able to specify how many offers
you should receive with another command line flag. Wish I knew C (a
lot) better, I'd add the code and send it back... If nobody has done it
by next year then I will re-learn C properly and write it.

and IP for hostaddress... Definately going to have to check this out.

Brian you are correct it is best practice to use the $HOSTADDRESS$ in
your check commands. Not doing so would require that you would need to
write a check command specific to each host and service. I am no expert
on this and have not used the plugin in the mentioned in this thread.

But I think maybe Marc is trying to say put the IP address in the
hosts.cfg when you define a host so you do not run into an issue with
DNS. So a host should be defined like this:
define host{
host_name   linux1.companyname.com
hostgroups  lin-servers
alias   Linux Server 1
address 192.168.125.15
check_command   check-host-alive
max_check_attempts  3
check_period24x7
contact_groups  localadmins
notification_interval 120
notification_period 24x7
notification_optionsd,u,r,f
}

Assuming linux1 is a http server I would write the check command for
this machine... well its straight out of the sample config.

# 'check_http' command definition
define command{
command_namecheck_http
command_line$USER1$/check_http -H $HOSTADDRESS$
}

You sure can, $HOSTADDRESS$. The recommendation was from the plugin
author but what he means is use an ip in your host{} definition's
host_address field instead of it's DNS name.

Well, there you go. :) I'm new to Nagios so perhaps this too is a
stupid question, but when you configure a check, can't you use a
variable for the host in the check command line? I guess I need to go
look at my config files again

check_nmap plugin for Nagios
Copyright (c) 2000 Jacob Lundqvist ([EMAIL PROTECTED])

Version: 1.21

Usage: check_ports [-v|--debug] [-H|--host host] [-V|--version]
[-h|--help]
   [-o|--optional port1,port2,port3 ...] [-r|--range
range]
   [-p|--port port1,port2,port3 ...] [-t|--timeout
timeout]

Options:
 -h = help (this screen ;-)
 -v = debug mode, show some extra output
 -H host= host to check (name or IP#)
 -o ports   = optional ports that can be open (one or more),
  no warning is given if optional port is closed
 -p ports   = ports that should be open (one or more)
 -r range   = port range to feed to nmap.  Example: :1024,2049,3000:7000
 -t timeout = timeout in seconds, default 10
 -V = Version info

This plugin attempts to verify open ports on the specified host.

If all specified ports are open, OK is returned.
If any of them are closed, WARNING is returned (except for optional
ports)
If other ports are open, CRITICAL is returned

If possible, supply an IP address for the host address,
as this will bypass the DNS lookup.

Check out the WebInject Nagios plugin.  I have it setup to check several 
pages in a secure website and it handles cookies.   It could save you 
the hassle of creating your our script.

Re: [Nagios-users] nmap

[Brian Loe]

Couldn't you write a script that diffs nmap results and report "0" if
diff doesn't come back with anything and "1" otherwise? nmap could be
cronned to run hourly - or so - and the results diffed with a baseline
file resulting in the code which nagios can cat... or something.

Sorry, not a developer but this seems easy enough for someone who is,
and I'd like to have it myself. :)

I have been thinking about this too. You could write a quick shell 
script to do this I guess, just take hourly reading and then diff them 
and warn if the port status has changed. Problem with this is that you 
can't really get the output cos nagios plugins are constrained to one 
line. Is there a good way to still get the output other than squashing 
it into one line? Would "stuff\nmorestuff" get around this if it's not 
immediately evaluated, but evaluated on the notify command? Or perhaps 
you could just output the whole thing normally and the web interface 
will take only the first line but the mail will show all lines?

Let me know what you come up with on this as I would also be very 
interested in doing this. Perhaps if we have an ongoing rolling 
discussion we could make this pretty good. I invite everyone to throw in 
their opinions and ideas on this

[Nagios-users] ARP

[Robin-David Hammond%KB3IEN]

I have a dumb-as-nails Motorola SIP adapter from  certain VoIP provider.

The think act closed on all tcp/udp ports and ignores ICMP echo request.

Mercifully the thing is hardwired to the nagios machine.

Anyone how a check_arp_tables script that will raise some kinda hell if 
the arp entry vanishes?

[Nagios-users] nmap

[Robin-David Hammond%KB3IEN]

Has anyone used nagios to track changes in the open ports on remote hosts?

I'm thinking that if the output of nmap changes one hour to the next that 
something ought to be investigated.

Sure it might be nothing, but might be a "OOh a root-kit! How Nice!" 
moment.

Hi,

You have to change the timeout of the plugins in the check command.
If the plugin is standard, the option is "-t"

And you have also to check the plugin execution timeout in the 
nagios.cfg file. But by default the value is 60 secs for services and 30 
for hosts.
So it should be enough.

[Nagios-users] plugin timeout setting?

[Dan Joseph]

Hi,

Is there a setting somewhere in the config for the plugin timeouts? 
We're getting some heavy traffic on a server and its timing out the 
plugins.  "CRITICAL - Plugin timed out after 10 seconds ".  I'd like to 
change that to 20 seconds if possible?

139 is a segfault I believe. Is the output of /bin/ping changing when
your primary DNS is down? Is it segfaulting. Have you tried running the
plugin manually when this is happing to see what's going on?

You might consider using check_icmp as it doesn't rely on /bin/ping for
processing.

  If you are good with perl, look at WWW::Mechanize. This allows

Nagios will only run a host check if a service on that host (any
defined) fails. This is a good thing. You can't make the host check
dependent on the failure of a specific check on that host (unless it's
the only service on that host). If that doesn't suit your purposes try
explaining what you want to accomplish better.

Re: [Nagios-users] check_http can't follow redirect properly, no cookies!

[Ton Voon]

No cookies in check_http, I'm afraid. It would be a nightmare enhance it to hold sessions.If you are good with perl, look at WWW::Mechanize. This allows you to store cookies and interact with a website as if you were a browser. We use this to login to monitor a betting site and retrieve funds information.On 17 Aug 2006, at 12:18, Hari Sekhon wrote:Hi,   I've got check_http doing a login which works fine and I'm using the -- to make sure I can fetch the secured page it's redirected to.The problem is that when the page is fetched it is fetched without the previously supplied credentials and therefore I get a login page instead of the page within the secure area.I really really need to get the page in the secure area.

[Nagios-users] Check ping error code 139

[Ilia Anokhin]

Hi everyone.

I've faced a strange thing using nagios - not long after primary DNS has
gone down, check_ping began to return error code 139 (Return code 139 is
out of bounds). Does any one know what was going on with it?

[Nagios-users] check_http can't follow redirect properly, no cookies!

[Hari Sekhon]

Hi,
   I've got check_http doing a login which works fine and I'm using the 
--onredirect=follow to make sure I can fetch the secured page it's 
redirected to.

The problem is that when the page is fetched it is fetched without the 
previously supplied credentials and therefore I get a login page instead 
of the page within the secure area.

I really really need to get the page in the secure area. Does anybody 
know how to make it store and use the credentials for the redirect. It's 
obviously not using it's cookie and I've looked through the --help but 
it makes not mention of cookies...


Thanks for any help in advance.

[Nagios-users] Trouble creating dependencies

[Nick Wales]

Hi,

I'm having trouble creating dependencies on my fairly small scale  
nagios installation

I am monitoring our remote office, which has a DSL link and VPN  
between here and there. As its DSL and on occasion goes down I'm  
trying to get nagios to stop monitoring the fileservers over there too.

I have created my dependencies.cfg file in etc/ edited nagios.cfg so  
the dependencies file is being looked at.

As a start I'm just trying to get nagios to not look at the 'Check  
host down' service on one of the fileservers over there, so here is  
my initial dependency within dependencies.cfg

define servicedependency {
dependent_host_name fileserver
dependent_service_description   Check Host Alive
host_name   curtainroadgateway
service_description Check Host Alive
execution_failure_criteria  c
notification_failure_criteria   c
}


Everything is critical at the moment because the office is empty and  
the fileservers are off, also the dsl is disconnected, yet nagios  
continues to show critical for the fileserver.

When starting up nagios there are no errors.

Any ideas what the problem is?

Thanks

Nick

I thought this was because of the redirect so I went back to --help and 
found --onredirect so now when I do --onredirect=follow it works fine 
and complains about the string.

Sorted.

[Nagios-users] check_http --url and --string don't work together?

[Hari Sekhon]

I can't seem to use --url and --string together. Url seems to make it 
not bother checking the string.

First I test the --string works as follows:

check_http -S -H www.somedomain.com --string=' 
The Wrong Nonexistent Web Page...'

which returns as expected. This is what I want to make sure it will warn 
me if it isn't finding exactly what I expect.

CRITICAL - string not found|time=0.210894s;;;0.00 size=6403B;;;0


But if I do

check_http -S -H www.somedomain.com --url="/some/path/" --string=' The Wrong Nonexistent Web Page...'

I get

OK - HTTP/1.1 302 Found - 0.110 second response time 
|time=0.110347s;;;0.00 size=690B;;;0


It doesn't check the string! Instead it just says that because some page 
was directed to that everything must be ok... ie False Positive.


The bigger picture:

I am trying to do testing of an https login page and get into a website. 
This requires that I log in via ssl and supply a username and password. 
The problem is that the login page will redirect to somewhere regardless 
of the result. If the login is successful you can get the internal pages 
and if unsuccessful it redirects to another login page. So I really need 
to get --url and --string working together to check the actual html.

I know there is webinject but I'd rather stick to check_http, it's much 
more straight forward and webinject's dependencies failed to install 
yesterday so I'd rather do this than bother fixing that just to try it.


Any ideas on getting this url and string business to work together?

Re: [Nagios-users] Daily status report?

[rob . moss]

What exactly is segfaulting?

You haven't provided much info to work with..

The script uses some basic Perl modules (libwwwperl) , so if there's
anything sefaulting it's related to your local box.

Make sure that you can run the reporting CGI's and Perl works, if not, you
need to fix them.
