Logs

Alle logs befinden sich in /var/log/samba/
Dieses Verzeichnis kann beim starten von smbd und nmbd mit der -l - Option geändert werden
- smbd -l /var/log/samba
- nmbd -l /var/log/samba
Standardmäßig legt samba log-Dateien für samba, smbd, nmbd, winbind, den Domain-Controller und die Domain selbst an. Um alles in eine Datei zu schreiben muss ein Verzeichnis in der smb.conf angeben werden
- ls /var/log/samba/

cores  log.nmbd   log.smbd        log.wb-DOUGLAS  log.winbindd
log.   log.samba  log.wb-BUILTIN  log.wb-LINUGGS  log.winbindd-idmap

Log-Verzeichnis in der smb.conf ändern

Es ist ebenfalls möglich das log-Verzeichnis in der smb.conf anzugeben

[global]
...
log file = /var/log/samba/smb.log
...

Diese Angabe schreibt alle .logs in die Datei smb.log, welche im Verzeichnis /var/log/samba liegt

Spezielle Einstellungen für Logs

für jeden verbundenen Client eine Log-Datei anlegen

[global]
...
log file = %m.log
...

für jeden Share eine Log-Datei anlegen

[global] ... log file = %S.log ...

Log-Level einstellen

Der Log-Level wird mit der Option "log level" oder "debug level" in der smb.conf angepasst

Log-Level 1 (standard)

/etc/samba/smb.conf

[global]
...
log level = 1
...

tail -f /var/log/samba/log.samba

samba: setproctitle not initialized, please either call setproctitle_init() or link against libbsd-ctor.
