Dear subscribers of the Genode mailinglist,
After some help by Christian Prochaska I managed to setup AMT SOL on Lenovo
X250. I thought I’d share my experience because there are some pitfalls of
which I was unaware.
On older systems like the Lenovo X201, you had to enable Legacy Redirection
Mode for SOL to work. Unfortunately for the X250 this option is no longer
available in the AMT <Ctrl-P> boot menu. Instead you can use wsman to set the
‘ListenerEnabled’ flag of the AMT_RedirectionService to true, and SOL will be
available.
Please note that you cannot run wsman on the machine that you're trying to
configure. wsman connects to the amt interface of the target machine and the
amt interface is not accessible from the machine itself.
So, on another machine, make sure you have installed wsman:
$ sudo apt-get install wsmancli
Then inspect the ListenerEnabled flag with wsman:
$ wsman get
http://intel.com/wbem/wscim/1/amt-schema/1/AMT_RedirectionService -h
<TARGET_MACHINE_IP_ADDR> -P 16992 -u admin -p ‘<YOUR_AMT_PASSWORD>'
If set to false, set it to true using:
$ wsman put
http://intel.com/wbem/wscim/1/amt-schema/1/AMT_RedirectionService -h
<TARGET_MACHINE_IP_ADDR> -P 16992 -u admin -p ‘<YOUR_AMT_PASSWORD>' -k
ListenerEnabled=true
For debugging you can increase the verbosity with the -d flag, e.g. -d 6.
Also note that the uri is not a url for a file on the Intel site ;-)
Thanks to Christian!
Met vriendelijke groet / kind regards,
Martijn Verschoor
