ich wollte in einer Virtuellen Maschine (vSphere) einen Client mit PXE-Boot konfigurieren - so dass ich an dem das neue Image immer weiter entwickeln kann. Leider funktionierte die Tastatur und Maus in LINBO nur für die Aufnahme der MAC-Adresse. Beim nächsten Booten erkannte LINBO dann weder Tastatur noch Maus. Hab vieles probiert und dachte dann, ein Upgrade hilft vielleicht (auch bei für unsere neuen Lenovo 13w-Convertibles).
Also nach Anleitung von 18.04 auf 22.04 und v7.2 geupgraded. Leider geht seit dem der DHCP-Dienst nicht mehr. Habe ich beim Upgrade eine Config-Datei überschreiben lassen?
Er findet die /etc/dhcp/devices.conf nicht - welche es auch nicht gibt

Wen du es nicht weißt, solltest du den aktuellen Inhalt der DHCP-Konfiguration vielleicht hier einfügen, damit dir andere Teilnehmer das sagen können oder die Chance haben Abweichungen deiner Konfiguration mit ihrer funktionierenden Version zu vergleichen.

Ich habe jetzt mal eine leere /etc/dhcp/devices.conf angelegt und damit scheint er sich zufrieden zu geben… sorry fürs stören…
Die beiden anderen Probleme kommen im neuen Thread…
Hallo Holger,
du hast leider recht. Habe die Datei angelegt und deinen Inhalt eingetragen… Nach dem leeren anlegen der /etc/dhcp/devices.conf kann ich zwar den DHCP wieder starten systemctl start isc-dhcp-server aber der linuxmuster-import-devices läuft fast 35 Minuten, wobei er lange nach der Ausgabe #### sophomorix-device finished OK! ### hängt:
Aus einem sophomorix-device --dry-run kann ich keine Probleme erkennen:

Ich habe nochmal ein linuxmuster-import-devices ausgeführt und dabei die /var/log/syslog angeschaut… Hier stand um 14:400 Uhr „nur“ folgende Einträge. Interessant ist die fünf-minütige Pause:

Auffällig finde ich den Eintrag dhcpd[3351]: data: host_decl_name: not available.
Kann damit aber nichts anfangen…
Hast du mal wieder eine Idee? Oder soll ich das Upgrade nochmal durchführen? Hab ja nen Snapshot davon…
nun kann es sein, das wir den Fehler ganz schnell finden: dann wäre das bequemer als snapshot zurück holen und nochmal machen, aber wir wissen ja nicht, wo das Problem her kam.
Das Upgrade sollte ohne Probleme laufen: wir wüßten ja dann nicht, wo das Problem lag und ob da nicht noch andere Leichen im Keller sind.
Insofern würde ich, wenn die Zeit dazu da ist, lieber nochmal zurück gehen und das Upgrade ganz genau nach Anleitung durchführen und genau hinschauen, ob da irgend wo eine Fehlermeldung kommt.
Also in der unteren Zeile fehlt ein „|“ vor dem usb-eth-1, so dass da die Spaltenanzahl nicht mit den restlichen Zeilen übereinstimmt.
Korrektur: Prüfe bitte, ob „1 usb-eth-1“ einge gültige Angabe für die Spalte ist. Die nachfolgende Fehlermeldung lässt den Schluss zu, dass dem nicht der Fall ist und dort nur eine Zahl erwartet wird, die mit int() versucht wird auf Integer zu konvertieren.
