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

For your first question:
If you remove auto eth0 then your eth0 interface won't start at boot.
If what you've posted is all your /etc/network/interface content where is the ppp connection configuration? Do you have your DNS configured?
FOLLOW-UP
All right. If you have your ppp working that's fine. To set a static IP you may need to have your DNS configured and add the following to your /etc/network/interfaces in addition to what you have already
BROADCAST 192.168.1.255
DNS-NAMESERVERS 8.8.8.8 # Supply here your DNS
I would rather have allow-hotplug instead of auto since the former allows the detection of events after the boot.

That's the thing. I have a separate script which executes the pppd command as given on the modem user manual. When I run the pppd command , then check ifconfig, I see my ppp interface. However i'm not sure if I need to configure this in the network/interfaces file. I'm new to this ppp stuff
