Nagios check_smb_status.sh -

i having little issue here plugin. when run locally on samba server machine works fine:

./check_smb_status.sh

total users/process:21 total machines:16 total files:67  |total users/process=21 total machines=16 total files=67 

but when run nrpe plugin nagios server it's output not correct:

./check_nrpe -h -t 500 -c check_smb_status

total users/process:0 total machines:0 total files:68  |total users/process=0 total machines=0 total files=67 

here source of check_smb_status.sh:

it's because nagios user cannot access files. can : chmod 666 /var/lib/samba/*.tdb , or 646 if think 666 devilish. of course, must keep in mind, security risk. , great samba power, comes great responsability :)
