==Openhab hacks ==
* log files are at ohab: [http://ohab:9001/ log files]
** change log settings in '''org.ops4j.pax.logging.cfg''' in the ''userdata/etc''' directory. The location depend on install, normally in '''/var/log/openhab2/etc'''.
* karaf console login: By default disabled from anywhere but localhost. Thus ssh into ohab, then ssh from there to <pre>ssh -p 8101 openhab@localhost</pre> default pwd is habopen.
* timeout exception prevents any further updates. This is evidently a eclipse smarthome framework bug<pre>2017-11-21 16:59:30.517 [WARN ] [org.apache.karaf.services.eventadmin] - EventAdmin: Blacklisting ServiceReference [{org.osgi.service.event.EventHandler, org.eclipse.smarthome.core.events.EventPublisher}={event.topics=smarthome, component.name=org.eclipse.smarthome.core.internal.events.OSGiEventManager, component.id=38, service.id=139, service.bundleid=109, service.scope=bundle} | Bundle(org.eclipse.smarthome.core_0.9.0.201711202142 [109])] due to timeout!</pre>
