Anyone know of any good ways to check VPN connections with Nagios?
Ping? If you can reach the remote end, the tunnel can be assumed
to be up.
HTH,
We use check_mailq from the standard nagios-plugins package.
I've used check_mailq also (with great success).
That assumes, of course, that this plugin is running *on* the Postfix
server in question.

Inside the tunnel, I can do that.
But I'm thinking of a scenario where I might set up a VPN (e.g. PIX,
Check Point, etc) and then continually check it every hour or so with a
test user.
Has anyone used Nagios to detect rogue DHCP severs?
I've got a complicated campus environment where people do things such as
plug in Linksys routers (the wrong way) and hand out DHCP addresses.

yes I've done this, by writing a bash script to wrap the check_dhcp
plugin and change the status code and output if more than the right
number of dhcp servers responded (also, you make sure the dhcp server
that responded is the right one using the check_dhcp plugin option.)

Going out and DHCREQUEST'ing and validating may be intermittent in
accuracy; you'd be best off with a SPAN port, tcpdump watching all DHCP
Client and DHCP Server traffic.
DHC-Offers should match a source MAC address(es) you certify.
Otherwise, ask your switching fabric to shutdown the port
Jeff,
The ncfg files for linux graphs does not work with Windows (except for
PING), you have to create/modify your windows ncfg file.
Run the command (plugin) in a terminal window , and the value you get after

can you explain why this would be intermittent in accuracy?
If there is another dhcp server present on the subnet, you will get an
offer from it as well, I have used this quite a lot and caught a

I'm in the process of switching from NRPE_NT to NSClient++ to monitor

monitor all automatic Windows services and notify if any of those are
not running.
On the Nagios server side I'm using version 1.4.9 of check_nt. If I run
Thanks for your help. I figured out what I was doing wrong and fixed it
already.

For whatever reason, I'm not getting what I'm expecting.
Oddly, I get the same OK result,

That sounds very reasonable; there's always the possibility that you won't

Indeed. Looking at the source of dhcpdetector.pl
(https://svn.bountysource.com/roguedetect/trunk/dhcpdetector.pl) it shouldn't
be too hard to modify it into a nagios plugin (trivial even).
