[[UPDATE PAST MIDNIGHT 31 OCT 2005

Finally got ADSL pppoe connection working in Brazil but it took a disproportionate amount of trial and error chasing odd tips from all over the place.
As a layman, seems to me DHCP was setting an IP address in Ethernet card eth0 when this and network mask should be blank as DLink DSL-500G modem is a bridge device, not a router to telco portal. Anyway, after doing the ADSL/PPPOE Configuration I typed ifconfig as root.

In ppp0 I found the telco inet addr: below

ppp0 Link encap:Point-to-Point Protocol
inet addr:200.165.217.131 P-t-P:200.217.72.8 Mask:255.255.255.255
...

which I grabbed to type as root

route add default gw 200.165.217.131

then pinged. All sending-receiving fine in this ping, so fired up browser and was off to the races to log in to ISP.

Can't believe serious users go through this rigmarole as I'll have to change the ppp0 telco inet addr: every time I connect this dynamic IP using Knoppix 4.0.2 Live CD, but I'd pledged to get connected with Knoppix before the end of the month and made it with ten minutes to spare (local time).

Test-driving Knoppix 4.0.2 LiveCD pulling hair out attempting connect HP Pavilion notebook (flawless with WinXP SP2 HE) to Internet via RJ-45, sole connection to D-Link DSL-500G Router (nothing else connected).
Strange, no difficulty connecting this notebook online with Ubuntu 5.10 LiveCD preview - a reboot from Windows XP merely typing username and password after issuing sudo pppoeconf command puts me online with Ubuntu Breezy Badger.
I like the fast loading and general superb look and feel of Knoppix LiveCD, so would like to get this working online.

Here's what WinXP command prompt ipconf reveals with WinXP connected before re-booting from Knoppix LiveCD:

Ethernet adapter Local Area Connection
Connection-specific DNS Suffix
IP Address 10.1.1.3
Subnet Mask 255.0.0.0
Default Gateway 10.1.1.1

PPP Adapter MyISPsname
Connection-specific DNS Suffix
IP Address 200.141.121.209
Subnet Mask 255.255.255.255
Default Gateway 200.141.121.209

Unable to get sudo pppoeconf or DHCP Broadcast to work in Knoppix netcardconfig I reply No to DHCP Broadcast and face a barrage of five values to answer. Can a kind soul tell me what octet to put in each netcardconfig box, please,

Please enter IP Address for eth0
Please enter Network Mask for eth0
Please enter Broadcast Address for eth0
Please enter Default Gateway
Please enter Name Server

plus any other tips to get Knoppix LiveCD online with ADSL.

Thanks for helping this Linux newbie.
