s_client is the literal string "s_client and instructs openssl to implement a generic TLS client.
“mender.example.com” is the FQDN of your Mender server.
Thank you @drewmoseley. I was finally able to start a deployment, but the rebooting does not end it remains at 99% ,The reason is that the ethernet configuration is not static because the network configuration systemd does not work so I made a configuration command line ip addr add but the configuration vanishes once a reboot is done.
Can you tell me how to establish a static network configuration other than the proposed solution on the doumentation ?
Thnak you
I don’t know enough about your setup to say. As discussed previously it depends on which NetworkManager you have running. I don’t know why the demo setup is not working for you.
Are you talking about NetworkManager runing on my linux computer ?
No. I’m talking about the network manager running on your Raspberry Pi. There are several choices in Yocto.
I did not build the image i am using the demo image built by mender, So i did not add or delete any packages
I’m not sure which image you are referring to. Where did you get the image?
The disk image i used is :
mender-raspberrypi3.sdimg.gz in the demo documentation https://docs.mender.io/1.7/getting-started/download-test-images
I just tested that image and it has systemd-networkd as expected. In my case, I was assigned an IP address over DHCP without any issues.
If you need a static IP address the following may be helpful: https://docs.mender.io/2.0/getting-started/deploy-to-physical-devices#set-a-static-device-ip-address-and-subnet
In which file you configured the dhcp ? And what are the lines you added ?
Thank you @drewmoseley
Nothing needs to change if you want DHCP. The meta-mender-demo layer sets that up automatically. It sounds like something is amiss in your local network configuration.
