Changing Network Configurations

June 18th, 2020


Log into the unit via local terminal or SSH on port 2222 with the 'mango' user and supplied password.

NOTE: All MangoGT come with a hostname and static IPv6 address based on the unit serial number for ease of configuration.  In the following examples, XXXX represents the numerical serial number of the unit.

  • hostname: mangogtXXXX
  • IPv6: [fe80::XXXX]

For example, mangoGT1234 would have hostname mangogt1234 and IPv6 address [fe80::1234]

To change the network settings, run the following command to access the network settings file:

sudo nano /etc/network/interfaces

Modify the eth0 adapter as needed.  The MangoGT is a DHCP client by default and the below entry is an example of changing it to a static IP.  Note that the default gateway and DNS servers are not required if they are not applicable:

allow-hotplug eth0
    iface eth0 inet static
    address 192.168.0.100
    netmask 255.255.255.0
    gateway 192.168.0.1
    dns-nameservers 192.168.0.1 8.8.8.8

When finished, type Ctrl-X to exit the file, followed by y to save changes, and Enter to overwrite the file.

If DNS servers are required when using a static IP, they will also need to be defined in the /etc/resolv.conf file.  Run the following command:

sudo nano /etc/resolv.conf

Modify the entry as needed.  Below is an example matching the previous network settings example:

nameserver 192.168.0.1
nameserver 8.8.8.8 (edited)
