What happens if remove auto eth0 from /etc/network/interfaces












0















I am using a BeagleBone and have two network interfaces. One ethernet interface which will connect locally to another device, and a ppp interface over USB which connects to a cellular modem.



I want the ppp connection to start automatically on boot-up and connect to the modem which I have set up running a script in rc.local. The ppp interface then receives a dynamic IP address from the ISP. This is fine



For the ethernet interface I would like a static IP address assigned to it , and for it to start automatically also. However, when I set auto eth0 in the /etc/network/interfaces file, the ppp interface then is not available on boot-up automatically as I would like.



What is the problem if I remove the line auto eth0 ? How can I enable both interfaces automatically? Thanks



Below is my /etc/network/interfaces file.



# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

#static IP address for eth0
auto eth0
iface eth0 inet static
address 192.168.1.80
netmask 255.255.255.0
gateway 192.168.1.1
