Freigaben auf BackupDC nach Update verschwunden

Hallo,

ich habe gestern meinen DC und meinen BackupDC aktualisiert. Alles scheint gut gelaufen zu sein, bis auf eine Sache: Die Freigaben auf dem BackupDC sind nicht mehr verfügbar.

In der Domänenverwaltung sind sie weiterhin eingetragen - die Verzeichnisse bestehen auch noch - alle weiteren Dienste und Anwendungen auf dem BackupDC (ownClound und Apache2, MySQL) laufen und können aufgerufen werden. Nur keine Dateifreigaben.

Interessant dabei ist, das mein IP Range bei 192.168.2.xxx liegt

Die anderen Logs sind ohne weiteren nennenswerten Hinweise. Hat jemand eine Idee, was ich noch überprüfen sollte und/oder woran es liegen könnte?

Wie ist die Ausgabe von ifconfig?

Naja da ist dann also schon mal klar woher die Adresse 169.254.231.43 kommt. Wird eth1 benötigt? Was ist die Ausgabe von

ucr search interfaces

Vielen Dank für deine Mühe und Rückmeldung.

Das eth1 wird zur Zeit noch nicht verwendet. Eine Zugriff über 192.168.2.xxx ist schon möglich. Ich greife über SSH und der 2er Adresse auf den Server zu. Was mich nur wundert ist, das es bis zum Update funktionierte und erst nachdem Update “verbogen” wurde/ist.

interfaces/.*/address: <empty>

interfaces/br0/type: static
 Defines the type of IP assignment: 'static' configures the interface according to the values configured in additional variables (e.g. 'interfaces/eth0/address'). 'dhcp' configures dynamic assignment over DHCP. 'manual' required manual configuration.

 If the variable 'samba/interfaces/bindonly' is set to 'yes', Samba only binds to the interfaces listed in this variable. Multiple entries need to be separated by blanks.

samba/register/exclude/interfaces: docker0
 This variable defines network interfaces which are ignored by samba (e.g. eth0). Multiple values need to be separated by blanks.

Warum das Problem erst jetzt auftritt weiß ich nicht. Ich sehe da nun drei mögliche Lösungen:

  1. Du löschst eth1 über die UMC
  2. Du deaktivierst eth1 generell:
ucr set interfaces/eth1/start='no'

Danach mußt du wahrscheinlich noch rebooten.

  1. Du deaktivierst eth1 für Samba:
ucr set samba/interfaces='lo eth0' samba/interfaces/bindonly='yes' samba/register/exclude/interfaces='docker0 eth1'

Bei der 3. Möglichkeit bin ich mir nicht ganz sicher, ob meine Anleitung so richtig ist.

Danke für die Tipps

Ich hab mich für die Variante 2 entschieden - Und nach einem Neustart waren die Freigaben wieder erreichbar

Danke und LG
