A few notes on HP's iLO.

You may get some interesting information about an iLO by using (at least) the following URLs (replace 10.x.x.x with the actual IP address of the iLO) - no authentication is required:

# curl -k ''
<SPN>ProLiant DL360 G7</SPN>
<PN>Integrated Lights-Out 3 (iLO 3)</PN>
<SN>ILOUSE235xxxx      </SN>

In addition, using a slightly different URL returns license information:

# curl -k ''
<?xml version="1.0"?>
<LNAME>iLO 3 Advanced</LNAME>
<IDATE>Wed Oct 23 13:05:29 2013</IDATE>
<SN>ILOUSE235D0M5      </SN>
<SBSN>USE235D0M5      </SBSN>
