samba - Mar 2015 - samba4 check database replication script. samba-check-db-repl.sh

Hai,???? 
?
I?have created a new?script for checking samba DC database replications. 
?
I?have tested with 2 DC's , if there people with more than 2 DCs, and want
to test for me, would be great.
I tested on debian wheezy, but should work on any apt-get capable os.? ( but
not?tested )
?

What it does.. 
- auto detects the?DC in you network. 
-?detects the DC met FSMO roles and compairs this db with all other DC's.? 
??? ( based on : 1 DC is running all the FSMO roles ) 
-?compaires with different settings. 
??? samba-tool drs showrepl and? samba-tool?ldapcmp
--filter="whenChanged"
- you can set these?check on or off per check.
- automatic checks for needed programs?and installs when not found.
- installs all needed programs without any questions asked.

- e-mail reporting when errors are found.? ( default only on errors found ) 
- if no sendmail program is found, installs postfix and sets relayhost for you
if needed.
????postfix wil be running on localhost only
??? relayhost is not needed if you have a "correct" dns setup. 
- can run as cron job, if administrator password is suppied in the script.
- run it without email address for console output only
- asks for Administrator password if not supplied in the script.
- colored output on console. 
- can run by change-ing only the "CONFIGURED=no" to yes

?
?
get it here: 
wget --no-check-certificate
https://secure.bazuin.nl/scripts/samba-check-db-repl.sh
?

Let me know what you think of this one..? 
Suggestions are always welkom.

Hi Louis, I am having a look at your script and I am sorry to say I have 
found a bug =-O

Line 124:

if [ "${SAMBA_CHECKDB_WITH_DRS}" = "no" ] || [ 
"${SAMBA_CHECKDB_WITH_LDAPCMP}" = "no" ] ; then

Should be:

if [ "${SAMBA_CHECKDB_WITH_DRS}" = "no" ] && [ 
"${SAMBA_CHECKDB_WITH_LDAPCMP}" = "no" ] ; then

The way it is written means that if either of the two variables is set 
to 'no', the script will print the error message and exit, I think you 
meant if both are set to 'no'

Darn.. and i did really my best to put on online without any bugs.. 
Still learning ... it gets better.. 
Thanks you fof having a look, i changed the code... 

And what do you think usable for the public? 

Greetz, 

Louis

Hi Louis, it should be very usefull, I know I will be using it in 
future. Just one or two little nit-picks :-)

You do realise that '! -z' is the same as '-n' ?

I also altered this:

if [ "${EMAIL_REPORT_ALWAYS}" = "yes" ]; then

to this:

if [ "${EMAIL_REPORT_ALWAYS}" = "yes" ] && [ -n 
"${EMAIL_REPORT_ADDRESS}" ]; then

Just a bit more error checking in case somebody wants to always send 
emails and doesn't add an email address.

Otherwise a very good script.
