Office 365: Enable mail forwarding to external email domains...

For a society i do some IT administration things - and now something really new: a Office 365 tenant.

First thing was to enable mail forwarding to external email accounts. Sounds easy - hmmm not really.

Configuring the forwarding in outlook.com is quite easy:

But this does not work:

Remote Server returned '550 5.7.520 Access denied, Your organization does not allow external forwarding. Please contact your administrator for further assistance. AS(7555)'

To change this behaviour you have to go to the admin settings:

https://protection.office.com/antispam

Now click policy:

Then choose Anti-spam:

And the chose the third entry and click "edit policy":

And the last step: Change Automatic forwarding to "on"

After you click save the email will now forwarded to external domains...

Microk8s: rejoining a node after a reinstall of microk8s

 

If you are running a microk8s kubernetes cluster, you can hit the scenario, that you lost one node and you have to reinstall the complete os or just the microk8s.

In this case you want to join this node once again to your cluster. But removing the node does not work, because the rest of the cluster can not reach the node (because it is gone...):

root@zigbee:/home/ubuntu# microk8s.remove-node ubuntu
Removal failed. Node ubuntu is registered with dqlite. Please, run first 'microk8s leave' on the departing node. 
If the node is not available anymore and will never attempt to join the cluster in the future use the '--force' flag 
to unregister the node while removing it. 

The solution is given in the failed answer: just add "--force"

root@zigbee:/home/ubuntu# microk8s.remove-node ubuntu --force
root@zigbee:/home/ubuntu# microk8s.add-node 
From the node you wish to join to this cluster, run the following:
microk8s join 192.168.178.57:25000/de0736090ce0055e45aff1c5897deba0
If the node you are adding is not reachable through the default interface you can use one of the following:
 microk8s join 192.168.178.57:25000/de0736090ce0055e45aff1c5897deba0
 microk8s join 172.17.0.1:25000/de0736090ce0055e45aff1c5897deba0
 microk8s join 10.1.190.192:25000/de0736090ce0055e45aff1c5897deba0

And then the join works without any problem:

root@ubuntu:/home/ubuntu# microk8s join 192.168.178.57:25000/de0736090ce0055e45aff1c5897deba0
Contacting cluster at 192.168.178.57
Waiting for this node to finish joining the cluster. ..  
 

Signal: Data backup of newer signal versions cannot be imported

 

I switched from Whatsapp to Signal (in terms of many communications are now on signal, but still some are left on Whatsapp) and afterwards i moved to a new smartphone.

But while doing the restore procedure for the backup (take a look here) i got this error:

Data backup of newer signal versions cannot be imported

or in german

Datensicherungen neuerer Signal-Versionen können nicht importiert werden

 

I investigated the version numbers on android playstore and both were 5.2.3.

On my new smartphone the android os was not on the latest release (on this new smartphone there was still some outstanding os versions to install).

But nothing did the job - i asked signal support, so let's see, what they are telling me...

EDIT: Even deinstalling signal on my old smartphone and reinstalling signal showed this error message...

MicroK8s: kubectl get componentstatus deprecated - etcd status missing

 

If you want to check the health of the basic components with

kubectl get componentstatuses 
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME                 STATUS    MESSAGE   ERROR
controller-manager   Healthy   ok        
scheduler            Healthy   ok        

Then etcd is missing.

This is a problem of a change in the api of kuberentes https://kubernetes.io/docs/setup/release/notes/#deprecation-5

The command to check etcd is:
