I set the following
And then did an Install Configured Options
After this, even though the ansible run failed, somehow at
Admin Console -> Configure -> Services Enabled
I found an option between
"Services for XO Laptops such as Registration, Backup, and the Activity Server"
"Moodle, a Courseware Manager and E-Learning Platform"
that has not been there before. It has been unchecked and reads:
"Chat and Collaboration Server for XO Laptops and Others"
(which perfectly sounds like what I'm looking for by enabling ejabberd)
AND what had has changed as well is the gateway. Yeahh!! Before this ansible run I could perfectly connect to the internet via ssh (Laptop -> WLAN-AP -> IIAB-ssh -> USB-to-Ethernet-Cable) for i.e. to do apt-get update but could not browse the net through the access point. Now I can.
I checked it and did another Install Configured Options that failed. Don't know how to test whether it did something to the system.
Unfortunetely I can not tell exactly how it evolved, because before this I curled for rpi 6.3 and don't know if this did something either positively or negatively to the system. So I have to do anything again with better following through what exactly I did after starting with the fresh 6.2 rpi lite sample .ziped image.
And now I'm curious how to find out whether an ejabber-deamon is working and how to use it. I have still not found any documentation on XO/sugar and XS/XSCE/IIAB collaboration.
PS: Oh, what I did as well is edit the ejabberd/tasks/main.yml as suggested by Jerry, cited by @georgejhunt at http://iiab.io/t/connect-sugar-user-to-school-server-group-rpi-iiab-6-2/76/6
Yet I have not done anything else to it (have not done the ./runtags ejabberd so far). Until I'm busy doing hat's what's following next I guess.
PPS: @georgejhunt , I have such an USB adapter for connecting the gateway through Ethernet. However I changed location in between ansible runs and kept it work having a power bank connected LOL. Kind of chaotic here at the moment. Have not thought about doing software development here, but there I go I'm looking in this ansible thing more and more from time to time. It looses it's scarry factor when I see things change to the better even though the run fails.
PPPS: @holt, No, I have not experimented with sugarizer yet, though I have seen it being available with my rpi 6.2 lite sample image. I may give it a try now to see whether I already can collaborate.
