Dear Sir,

I am writing to thank you for the bug report and say

No,

Here is an example against an NT 4 SP6+ spooler (plugin in 'debug' mode)

tsitc> /usr/local/nagios/libexec/check_ms_spooler -H ipaprint -u 
foo -p bar -d
/usr/local/samba/bin/smbclient //ipaprint/BS22 -U foo%bar -c 
'queue; quit' ==>
"added interface ip=10.0.100.252 bcast=10.255.255.255 nmask=255.0.0.0
 Domain=[IPAUSTRALIA] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0]
"
$queue_report for $printer BS22: ""

/usr/local/samba/bin/smbclient //ipaprint/GW01 -U helpdesk%helpme -c 
'queue; quit' ==>
"added interface ip=10.0.100.252 bcast=10.255.255.255 nmask=255.0.0.0
 Domain=[IPAUSTRALIA] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0]
 370      9656         CurrentDocument
"
$queue_report for $printer GW01: "370      9656         CurrentDocument"

/usr/local/samba/bin/smbclient //ipaprint/IT06 -U helpdesk%helpme -c 
'queue; quit' ==>
"added interface ip=10.0.100.252 bcast=10.255.255.255 nmask=255.0.0.0
 Domain=[IPAUSTRALIA] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0]
"
$queue_report for $printer IT06: ""

 ... snip ...

Ok. Connected to 17 queues on //ipaprint. Queue GW01: 370      9656         
CurrentDocument

or for an empty spool

tsitc> /usr/local/nagios/libexec/check_ms_spooler -H ipaprint -u 
helpdesk -p helpme 
Ok. Connected to BS12 BS17 BS23 IT06 IT17 N005 N102 S003 S006 S102 S223 
S322 S401 TA25 TH02 TS10 TS30 queues on //ipaprint. All Queues empty

The plugin like many in the contrib directory wraps an executable (the 
Samba project smbclient) and attempts to parse its output.

Also note that paths in contrib plugins _must_ be corrected to suit your 
site.

Problems with this approach include :-

1 plugin fails if smbclient not installed

2 plugin fails if smbclient is not what plugin is expecting.

In this case, the plugin has only been tested against NT servers whose 
SMB file server listens on port 139; 2K boxen on the other hand may 

1 produce different smbclient output

2 may not accept connections on port 139 - which smbclient _may_ be 
trying.

Please would you 

1.1 Ensure that smblclient is installed in a path that agrees with what
is hard coded in the plugin (cringe). Edit plugin as required.

Here is the villain

use constant SMBCLIENT_PATH     => '/usr/local/samba/bin/smbclient' ;

1.2 Ensure you have a valid spooler account and password.

Try this,

 smbclient //spooler/queue -U User%Pass -c 'queue; quit'

and see if the output is sensible.

2 Run the plugin with -d option and post me the output.

3 Make sure that the plugin is connecting to the spooler - the errors 
should tell you if it's not but you may need to try

tsitc> /usr/local/nagios/libexec/check_ms_spooler -H ipaprint -u 
foo -p bar > & /dev/null & ; tethereal -q -l host ipaprint |&

(Change shell redirection chars |& and >& if you don't use C shell.  
Tethereal is part of the _excellent_ ethereal package; use tcpdump
otherwise. [Note the spiffy ethereal SMB decode courtesy of the Samba
team]).

Please send me this output if the suggestions above aren't helpful.

continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a

me, because I am involved in mankind; and therefore never send to know
