2.8 Take Down the Ethernet Interface
A PPP connection requires that any existing Ethernet connection be taken down. To
bring down the Ethernet connection, type the following command:
# ifconfig eth0 down
(Optional) To verify that the Ethernet connection is down, type:
# ifconfig
followed by the enter key. ​
eth0
​ should not be listed.
2.9 Bring Up the PPP Interface
To enable the PPP interface, type the following commands:
For Debian:
# pon att-TNAG
For Ubuntu:
# pppd call att-TNAG
followed by the enter key. You will see the second script you wrote appear on the
screen, followed by the network communication the Skywire modem is going through to
get connected.
Once the process is complete, test the connection:
#ping –c 2 www.google.com
and you should receive a response similar to this:
PING ​ www.google.com ​ (216.58.216.196) 56(84) bytes of data.
