[Gelöst] pxe-e32 tftp open timeout und bootcd Anmeldung

[Toni]

Hab den Server jetzt schon aufgesetzt diesmal auf Ubuntu, selbes Problem:

Code: Alles auswählen

PXE-T04: illegal(unregconized) tftp operation
PXE-E36: Error received from TFTP derver
PXE-M0F: Exiting PXE ROM

Code: Alles auswählen

lsof -i | grep tftp

gibt folgendes zurück:

Code: Alles auswählen

xinetd    1039      root    5u  IPv6   9299      0t0  UDP *:tftp

Sollte da IPv6 stehen?

ich nutzte einen Server 2008r2 als DHCP und DNS, hoffe die Einträge stimmen.
option 066 (name des server) opsi
option 067 (startdatei) linux/pxelinux.0

[SisterOfMercy]

dhcp option 66 should be the IP adress or the FQDN.

What is the output of sestatus?

[Toni]

changed option 66 to fqdn -> no changes

sestatus-> not installed

[SisterOfMercy]

sestatus-> not installed

Oh, right.. Ubuntu uses crapparmor.. Well, somehow find out if that is still running and perhaps if it is enforcing.

Das ist rausgekommen

apparmor module is loaded.
5 profiles are loaded.
5 profiles are in enforce mode.

   /sbin/dhclient (868)
   /usr/sbin/mysqld (1063)
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.

[SisterOfMercy]

Try setting all profiles in complain mode, I think this is supposed to allow actions, but complain about them.

On CentOS you have to set SELinux to permissive or create a policy, which includes TFTP actions.

done

same error on client side

Code: Alles auswählen

PXE-T04: illegal(unregconized) tftp operation
PXE-E36: Error received from TFTP derver
PXE-M0F: Exiting PXE ROM

[SisterOfMercy]

Is this one client or do all clients give the same error? If it's one client you might want to try a bios update.

[Toni]

all clients give the same error

solved, server network card broken
