PPPoE muddle in Debian over Ubuntu: a story
I have to admit that network scripts in RedHat/CentOS/Fedora, and also SuSE and even Mandriva, are somehow better than the Debian way, in some particular occasions.
My case involves a SpeedTouch 360 ADSL Modem (Ethernet), and a PPPoE connection.
If the ADSL modem is ppp0 and the Ethernet card connected to it is eth0, it's obviously enough that Roaring Penguin's PPPOE module (rp-pppoe or pppoe) will take care of configuring eth0 -- eth0 will be configured with DHCP.
Everything works 100% hassle-free in "whatever RedHat-like" (including SuSE). What happens weird in Debian Sarge, Debian unstable and Ubuntu?
