Re: [Bacula-users] Read all config files in a directory

I was playing with a combination of includes with "@|" and using m4 to generate the included files.

Ex:

# more gen_clients.sh
#!/bin/sh
m4 -D CLIENTNAME="kestrel" \
-D CLIENTPASS="PFV8i2UZ1c:p=47ZG5@Tc5pLmxFw04TaOaqa;MgDO;Mv" \
/etc/bacula/conf/clients/fd2.m4

fd2.m4 is a client config with the symbols CLIENTNAME and CLIENTPASS substituted in to define the client, jobs, disk storage and disk storage pools.

Ex:

Client {
Name = CLIENTNAME-fd
Address = CLIENTNAME
FDPort = 9102
Password = "CLIENTPASS"
.
.
}

Job {
Name = CLIENTNAME
.
.
.

The shell script that calls m4 can be included into bacula-dir.conf with "@|". I got busy and didn't finish the job. I'll have to make some time to do it since it would reduce the number of config files I have to maintain to a small fraction of what I have now. The sd(s) can also be configured with this trick.

That's not a real password, of course. Btw I generate new passwords like this:

# more 44rand.pl
#!/usr/bin/perl -w
for (1..44) {
$s .= chr(int(rand(75))+48);
}
print $s . "\n";

Not exactly cryptographically strong, but better than making them guessable or all the same.

IIRC, you could also use an include like "|cat /etc/bacula/dir/*.conf" 
- I haven't treid that myself, and it's possible you need to use a 
shell and add more quoting, like in "|/bin/sh -c '/bin/cat 
/etc/bacula/dir/*.conf'" or something.

Yup, it is possible indeed. I just tested it with a simple script:
#!/bin/sh
cat /usr/local/etc/bacula/$1/*.conf

..and then included all my clients into the configuration:
@|"/usr/local/etc/bacula/sh/catConfig.sh client"

So keeping configuration in MySQL is not a problem at all.. gooood :)
