Come da richiesta di Stefano sono a riproporre qui un post che ho pubblicato nel forum dedicato a Sme8. (link al post in inglese
http://forums.contribs.org/index.php/topic,47393.msg233852.html#msg233852Stavo cercando di far funzionare l'audit di Samba sotto Sme8beta6.
Situazione:
sto usando diversi contrib, tra i quali l'utile (almeno per me) SharedFolder. Ora ero intenzionato ad abilitare l'audit di Samba, ed ho iniziato a documentarmi. Ho trovato alcuni articoli già pubblicati sul forum, e sono partito da questi per trovare una soluzione al mio problema.
Il primo
http://forums.contribs.org/index.php?topic=46444.0 parla appunto di abilitare l'audit sulle i-bay ma, lavorando su un contrib che crea la sue proprie cartelle condivise, purtroppo non funziona.
Andando avanti nella lettura sono imbattuto in
http://forums.contribs.org/index.php?topic=35872.0 ed in
http://a32.me/2009/10/samba-audit-trail/, così ho iniziato a modificare a mano i fragment del samba di modo da far funzionare il tutto.
Ho modificato il fragment di sharedfolder (/etc/e-smith/templates/etc/smb.conf/90shares
{
# process all information-bay directories
use esmith::AccountsDB;
my $adb = esmith::AccountsDB->open_ro();
foreach my $share ($adb->get_all_by_prop(type => 'share'))
{
if ( ($share->prop('smbAccess') || 'browseable') =~ /browseable$/ ){
$OUT .= esmith::templates::processTemplate (
{
MORE_DATA => {
share => $share,
},
TEMPLATE_PATH => "/etc/smb.conf/shares",
OUTPUT_TYPE => 'string',
});
}
else{
$OUT .= "# ".$share->key." access is disabled\n";
}
#inizio nuovo codice
$OUT .="# Audit settings
full_audit:prefix = %u|%I|%S
full_audit:failure = connect
full_audit:success = opendir mkdir rmdir open write rename unlink
full_audit:facility = local5
full_audit:priority = notice
"
#fine
}
}
Ho eseguito /sbin/e-smith/expand-template /etc/smb.conf e quando vado a controllare in smb.conf la modifica è avvenuta

Ma in messages non compare traccia dei log dele operazioni sui file.
Dietro consiglio di Stefano ho eseguito testparm senza che riscontrasse errori nei file di configurazione ed ho modificato il fragment nel seguente modo:
{
# process all information-bay directories
use esmith::AccountsDB;
my $adb = esmith::AccountsDB->open_ro();
foreach my $share ($adb->get_all_by_prop(type => 'share'))
{
if ( ($share->prop('smbAccess') || 'browseable') =~ /browseable$/ ){
$OUT .= esmith::templates::processTemplate (
{
MORE_DATA => {
share => $share,
},
TEMPLATE_PATH => "/etc/smb.conf/shares",
OUTPUT_TYPE => 'string',
});
}
else{
$OUT .= "# ".$share->key." access is disabled\n";
}
$OUT .="# Audit settings
#modifica al precendente
vfs objects = full_audit
#fine modifica
full_audit:prefix = %u|%I|%S
full_audit:failure = connect
full_audit:success = opendir mkdir rmdir open write rename unlink
full_audit:facility = local5
full_audit:priority = notice
"
}
}
Ora finalmente riesco a vedere i log in messages!
Grazie Stefano!
Prossimo step spostare i log in un file separato, inserirò i progressi di modo da agevolare la vita al prossimo che incapperà nel mio solito problema!
