Nagios-users digest: check_wins. Please don't post in HTML.

[Alex St. Amand]

Thank you.  I had not tried it at the CLI as the nagios user only as root.
The problem was that the path in the plug-in contained the word netsaint
instead of nagios for the common lib path.  Fixing that fixed the problem

Dear Sir,

I am writing to thank you for your letter and say my reply is way way 
way down below that ugly HTML your mailer mangled your letter into.

The main problem that plugins like check_wins encounter is that the 
Nagios user cannot access the binaries that a program such as this needs 
to operate.

Please note that check_wins is a contrib plugin and therefore requires 
explicit path changes to work (core plugins work hard to find the path 
to Samba and so on and then edit the source to accordingly in the 
configure processe).

This may help

. su nagios (or whatever your Nag user is)

. run the plugin from the CLI

==> works ? some sort of permission problem with the Samba binary 
nmblookup (can't imagine what since on this system
tsitc> ls -l /usr/local/samba/bin/nmblookup
-rwxr-xr-x  1 root  wheel  516027 Apr  9  2003 
/usr/local/samba/bin/nmblookup
tsitc> )

==> doesn't work ?

Please post your

1 plugin version: 

(tsitc> /usr/local/nagios/libexec/check_wins -V
check_wins (netsaint-plugins 1.2.9-4) 2.8

tsitc> )

2 Samba nmblookup version:

tsitc> /usr/local/samba/bin/nmblookup -v
nmblookup: illegal option -- v
Usage: nmblookup [-M] [-B bcast address] [-d debuglevel] name
Version 2.2.8a

FWIW, I have been using check_wins for some years, and I know of at 
least one other site that is using it.

3 The definition of check_wins from checkcommand.cfg and how you are 
calling it from services.cfg

NB. You __must__ provide the -D and -C parameters

Perl Check WINS plugin for NetSaint.

Returns OK if the addresses of domain controllers are found in the list 
of domain controllers returned in the WINS response to a 'domain 
controllers query' 

Why would you want to do this ?

MS File server clients insist on connecting to file servers using 
NetBIOS names.
If they __don't__ resolve NetBIOS names with a WINS (NBNS) then they'll 
either fail to logon and  connect to shares or they will
broadcast requsts for names.
Both problems are eliminated by a healthy WINS.
Also, you may have a MS domain spanning a  number of WAN connected 
sites, with domain controllers far away from powerful local
domain controllers.
In this case, you want your local clients to have their logon requests 
validated by the local controllers.

The plugin works by
  asking the WINS to resolve the addresses of the domain controllers 
(supplied by -C or from the constant MY_DCS)
  asking the WINS to return the list of addresses of the domain 
controllers able to validate requests for the domain
   whose name is given by -D
  returning Ok          if all controller addresses are in that list (of 
addresses of domain controllers) or
  returning WARNING     if not all the controller addresses are in the 
list or
  returning CRITICAL    if there is no reply from the WINS or the list 
contains none of the contoller addresses

Usage: check_wins -W <wins> -D <domain>

-W, --wins=STRING
   Hostname or address of the WINS (Either Samba/nmbd or MS product)
-D, --domain=STRING
   MS Domain name to find the Domain controllers of.
-C, --controllers:STRING
   Optional __name(s)__ of domain controller that __must__ be found in 
the response to a domain controller name query.
   If not defined, then use the constant value MY_DCS. You must use 
either -C or make sure that MY_DCS contains the names 
   of __your__ domain controllers.
-T, --timeout:INTEGER
-d, --debug
   Debugging output.
-h, --help
   This stuff.
