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 für samba, smbd, nmbd, winbind, den Domain-Controller und die Domain selbst eine log-Datei 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
