Hello everyone,
I have a couple of related questions regarding service dependencies in
Nagios and their limitations. I have two service checks (let's call
them A and B) and service A depends on service B to function
correctly. I want to set Nagios up so that if service B crashes then
both services
Is there any plugin exist to detect rogue dhcp servers across all vlans/ subnet?
I have had a look at two programs (not Nagios plugins): dhcp_probe and
roguedetect - none suitable for human consumption yet. There is an
excellent program on Windows call "dhcploc.exe" but I'm on Linux.
Thanks.

It doesn't appear to me that the configuration syntax has changed
significantly, but I haven't used 3.x yet.
NACE updates your templates, so the syntax shouldn't matter much. If
you write Nagios 3.x configs, and let NACE reuse them with variable
replacement, there shouldn't be a problem.
Thanks.

I am no expert but AFAIK it merely encrypts the traffic ie, no
certificates at all.

What does "fails" mean in this context? Timeout? No route to host? Does
this happen for all hosts, or just for one host? Does it happen for
local hosts on your own subnet as well as for remote hosts behind a router?

I encountered this too. My solution was a script in /usr/local/scripts
called by cron that stops the NTP daemon, runs "ntpdate "
twice, then restarts the NTP daemon. This runs in cron every 2 hours and
seems to keep things in sync...

check_icmp and check_ping can check a particular device but native ping fails.

Hi Idriss,
What I think? I think I learned something new! Thanks for telling me
about the NRPE-with-SSL option; I was not aware of that.
That said, I suspect that the overhead for SSL and SSH will be very
similar, because under the hood they use quite similar algorithms. I

Hi,
create a check which will fail for sure and comment it in nagios.cfg.
Create an event handler, then when you need just enable the check in the cfg
and restart nagios.
That's all.

Hi Russell,

Yes
nrpe will alow you to execute remote commands.
if the service execution you define is refering a command executed via nrpe on
a remote server , you
should get the same response as if nagios exeuted the service normaly.

Hello Marc,
Thanks for your answer. In fact I find a solution.
My Syslog-NG server which receives all Bluecoat messages send a SNMP TRAP
when it detects a "status changes in the failover" with Regex.
FInally, Nagios create an alarm in my TRAP service for my bluecoat.
Best regards

Is there any plugin that allows such a functionality?
Is it possible to use NRPE?

Hello,
I know that Nagios is able to issue actions through the use of Event Handlers.
Is it possible to also manually issue an action (ex. launching a script)?
I mean, can an operator decide to launch a script via the nagios interface?
Many thanks

Answering to myself:
pnp4nagios is better than nagiosgraph (sorry me nagiosgraph's
developers). I recommend anyone to use pnp4nagios.

You can also try going to http://localhost/nagios/index.html to verify your
directory index directive is being carried through properly within the
Apachy configuration. I ran into an issue recently when switching to SSL, I
could no longer browse directly to Nagios and had to add the DirectoryIndex
