Network and 3G configuration on NEXCOM NISE50 with Ubuntu Core 16.04
This article shows how to configure the network on the Nexcom NISE50 running Ubuntu 16.04.
Setting a static IP
To set up an static IP follow this steps
Edit the /etc/network/interfaces file
azeti@Nexcom-Master:~$ sudo vi /etc/network/interfaces
Set the IP, gateway and DNS for each interface (enp2s0 for Ethernet 1 and enp3s0 for Ethernet 2)
allow-hotplug enp3s0 iface enp3s0 inet static address 10.0.0.1 netmask 255.255.255.0 gateway 10.0.0.100 dns-nameservers 8.8.8.8 8.8.4.4Start the connection
root@Nexcom-Master:~#sudo ifdown enp3s0 ;sudo ifup enp3s0
Creating a 3G Connection
To create a mobile connection, execute this commands with the proper information
The exact command to create a new connection depends on the 3G card model used and the sim card provider. Different cards will use different interfaces (ifname) and different sim providers will use different apn, user an password.
To check the port to be used execute the command 'sudo mmcli -m 0' and check the System / Primary Port
root@Nexcom-Master:~# mmcli -m 0

Troubleshooting
- To check the assigned IP used "ifconfig"
To list the created connections use "network-manager.nmcli con"
root@Nexcom-Master:~$ nmcli con NAME UUID TYPE DEVICE TELEKOM_GSMDEMO d472ed41-113a-4a37-972c-6517e335f3cf gsm ttyACM3
To check the configuration of each connection use the command "nmcli con show connection-name"
