iLO 4 Reset – How to Reset to Default Without Credentials

This is most likely a firmware bug, but the only situation I've heard of that -sources- packets from 0.0.0.0 is RARP (reverse ARP) which sends out requests from an all zero MAC to find its IP address. This used to be a component of diskless boot once upon a time but hasn't been seen in quite a while.

It may be that the pinging station still held the ILO's MAC address in cache - and, of course, the intermediary switch. If the ILO had lost its address it could have been going through a RARP / BOOTP process. Or it just lost its mind.

All of HP's example scripts use <RIBCL VERSION="2.0">, but that's the only difference I see. I'm also not sure whether renaming a user in this way will actually work, so maybe that's it. Try just changing the password:

<RIBCL VERSION="2.0">
   <LOGIN USER_LOGIN="Administrator" PASSWORD="does-not-matter">
      <USER_INFO MODE="write">
         <MOD_USER USER_LOGIN="Administrator">
            <PASSWORD value="new-password"/>
         </MOD_USER>
      </USER_INFO>
   </LOGIN>
</RIBCL>

Also be aware that characters <>"& are not supported properly in passwords (iLO's don't quite parse XML correctly).

If that still fails, try using hpilo_cli, which can generate XML for you and pipe it through hponcfg.
