ADSL on Ubuntu 9.10 (Karmic Koala)

Working with ADSL modems on Ubuntu 9.10:

Configure: pppoeconf

sudo pppoeconf

Check: rohit@lenovo:/etc/network$ more interfaces auto lo iface lo inet loopback iface dsl-provider inet ppp pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf provider dsl-provider auto eth0 iface eth0 inet manual
Start: pon
rohit@lenovo:/etc/network$ sudo pon dsl-provider Plugin rp-pppoe.so loaded. RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5
Stop:poff
sudo poff
Log:plog
rohit@lenovo:/etc/network$ plog Dec 8 16:37:45 lenovo pppd[11102]: Plugin rp-pppoe.so loaded. Dec 8 16:37:45 lenovo pppd[11102]: RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5

This method works well for BSNL's ADSL lines in Kolkata.
