[Gelöst] Named Pipe wird mit Nullbyte erzeugt

[sunnysky]

Hallo,
ich habe eine neue opsi Installation gemäß Handbuch auf einem Ubuntu 20.04 Rechner installiert.
Opsi an sich läuft prima, aber wenn ein Client versucht sich über pxeboot die Bootdatei zu holen,
liefert der Server zwar die Datei an den Client aber dann passiert nichts mehr.

Hier die Protokiolle:

Der Opsi server liefert die pxelinux.0 Datei per TFTP an den PXE boot client aus
jedoch scheint es dann nicht zu einem weiteren Bootvorgang zu kommen.

Die Named Pipe Datei die beim setup des Netboot Produktes angelegt wird hat leider Nullbyte und
enthält keine weiteren informationen.

Reinstall des opsi-tftpd-hpa und des opsi-linux-bootimage Paketes mit anschließemdem restart sowie
das neue setzen von Berechtigungen mit opsi-setup --set-rights hat an diesem Nullbyte verhalten nichts geändert.

Was kann ich tun damit damit die Named Pipe Dateien mit den erforderlichen Bootkomandos geschrieben werden?

Danke und Grüße

Hier endet der Log Eintrag, die Erstellung von Pipe Informationen wird hier nicht mehr angezeigt.

[SisterOfMercy]

Are you sure the named pipe is empty? When I create one the size is also 0. Reading it with cat shows what was in there. Of course you would then have to setup the netboot product again, because the file has disappeared.

Are you using a client with legacy boot? And what kind of client is that? Furthermore you say nothing happens any more on the client, but what do you see on the client?

[sunnysky]

Danke vielmals, das war der richtige Hint .

Ein cat der Named Pipe hat die richtigen Informationen geliefert obwohl diese Nullbyte anzeigt.

Mein Client hat versucht PXE mit UEFI zu booten und konnte daher den Bootvorgang nicht weiterführen da
mir das UEFI Modul fehlt.Legacy boot mit einem anderen System funktioniert jetzt.
