Hello @MarekBelisko @mirzak @drewmoseley, i want to do set a static ip to my raspberryn in which file can i do it ? ---

Thank you @MarekBelisko. I tried this configuration but nothings seems to be changed before anf after a reboot , i checked this by runing ifconfig -a Otherwise i would like to know how to synchronize the clock because the system clock isn’t synchronized, i checked by runing timedatectl status. Thank you ---

What do you mean nothing was changed? By means of IP address assigned? Above configuration should work (maybe try to update `Name=enp*` in my example). Just noted it now that in original one was used this one. ---

This is what i wrote on enp.network ```auto [Match] Name=eth0 [Network] # static IP # 192.168.100.2 netmask 255.255.255.0 Address=192.168.100.2/24 Gateway=192.168.100.1 DNS=192.168.100.1 ``` Instead i run : ip add add 192.168.100.2/24 dev eth0 This command changes my ip adress Otherwise have you an idea about how to synchronize the clock ? Thank you ---

> [@MissLee](#): > > Name=eth0 try to update to: ```auto Name=enp* ``` and see if it works. For time synchronization there should be present systemd service (or ntpdate). But if you are not connected to internet then it will not work. ---

Ok @MarekBelisko When i run `systemctll status mender`it returns Autorization request to mender Docker failed, it means that i can’t connect to mender server which is the case because i can’t see my device pending on the UI. I am confused because Mender server is local on my host and i can ping to the ip address of my host and [s3.docker.mender.io](http://s3.docker.mender.io) and [docker.mender.io](http://docker.mender.io) do have the same ip address as my host. What do you think this isuue is due to ? Thank you ---

Probably because wrong time on RPI as certification verification need precise and actual time on platform. ---

SO i should be connected to internet to synchronize ? ---

Yes. Correct time is required for certificate processing. See [https://docs.mender.io/2.0/troubleshooting/mender-client#certificate-expired-or-not-yet-valid](https://docs.mender.io/2.0/troubleshooting/mender-client#certificate-expired-or-not-yet-valid) for more details. Also, regarding network configuration with the enp.network file as discussed above, that assumes you are using systemd-networkd for network management. This is the default if you use the meta-mender-demo layer but it may be different in your system depending on configuration. The following commands should confirm if you are running this configuration and have time syncing configured through systemd: > ``` > # systemctl status systemd-networkd > # systemctl status systemd-timesyncd > # timedatectl > > ``` Other packages that can replace systemd-networkd are connman and NetworkManager (and likely others that I’m unware of. To determine if either of these are running: > ``` > # systemctl status connman > # systemctl status NetworkManager > > ``` ---

Thank you @drewmoseley, i will try this commands. My question is : is it ok to use the command ip addr add x.x.x./y dev eth0 to configure an ethernet ip adress ? and how the raspberry is supposed to do the pull in for an update ? is there any commad to enable the pull in ? THank you ---

I think using the ‘ip addr’ command will work just fine but systemd may take control back and try to set it up based on how you have the enp.network file configured. Maybe doing “systemctl stop systemd-networkd” will work around that but I’ve not tested it. The Mender client is setup to run as a daemon and periodically checks the server for updates so you don’t need to do anything to trigger on the client side. Once a deployment is created in the Web UI then it will happen on the next device poll. ---

Those systemctl status commands should all be run separately to determine your configuration. ---

Exactly i run them separately and they return the same thing ---

which means these services are not found ---

Yeah, that’s not surprising. I assume your system is using systemd-networkd unless you have explicitly changed it. ---

Ok thanks @drewmoseley i will check that. I would like to know which ports are used in the raspberry to communicate with the server ( send and receive ) ? Thank you ---

Details are here: [https://docs.mender.io/2.0/getting-started/deploy-to-physical-devices#network-connectivity](https://docs.mender.io/2.0/getting-started/deploy-to-physical-devices#network-connectivity) There are no open ports required on the client. ---

Thanks @drewmoseley. Do you have an idea about this command in the trouble shooting section: echo | openssl s\_client -connect [mender.example.com:443](http://mender.example.com:443) 2\>/dev/null | openssl x509 -noout -dates Is the s\_client my raspberry pi 3 and [mender.example.com](http://mender.example.com) the id of my mender user ?
