how to connect to internet using ASDL

Dear all,

i am a Linux newbie recently installed Lorma Linux 4.0 in my PC (using
dual-boot). Till now i cannot connect to internet using ADSL. i have
consulted my ISP but recently they have very limited support for Linux, they
only provide FAQ for Linux on 56K dial-up, but not broadband (ADSL). i ask
the ISP support who told me they can use rp-pppoe to connect in Linux, no
specific setting required, but i failed.

Here is the details,
<<< after boot-up, i tried the followings,

This shows, that your network card is not set up to be used.
Well, i don't know about the type of your DSL modem (got it from
your ISP). If it is connected via Ethernet to your netcard,
i think you have to give eth0 a static IP to get it to work
with the modem.

At least my gateway box does so (though i certainly have
a totally different DSL modem).
I set up eth0 with some (nevermind) static private IP and the rest
is done by your pppoe-Tool (when it is set up correctly).
So i suggest to try this, too. Take e.g. IP 192.168.22.1
netmask 255.255.255.0

How you can set up eth0 with such an IP, depends on your
distro.....
You can use ifconfig, of course, but you should make sure
that your settings are kept for each boot of your box....
so look for the appropriate config files.
Maybe the installer of your distro did set the device
to (auto) DHCP-configuration which will not work, when
eth0 is connected to a simple DSL modem.....

Maybe you should set DEMAND=yes.
If you do so,each time internet access is requried,
your pppoe will dail up automatically.
If you leave it this way, you will have to start
pppoe yourself, when you want to go online.

Well eth1 is usually present, when your PC has 2 netcards.
Maybe the howto reffered to a PC which might be used as a
internet gateway for a LAN (1 NIC would be connected to the
DSL modem and the other NIC to the LAN).
Nevermind this for your basic problem when you just want to go online
with your linux box.

I'm not even sure the NIC needs an IP. At least it works also when
assigning it IP 0.0.0.0

I've never heard of tkpppoe until just now.

Looks good. You don't need any IP address for the Ethernet interface
that's used with PPPoE.

The real question is "Why do you have a network route for 169.254.0.0/16
assigned to the loopback interface?" Smells like Wintendo.

It could be an alias for eth0, although I have no idea why it's there.

It may be a distribution-related thing. Look through the system
configuration files in /etc/<whatever>/ and/or find a way of getting
rid of it. Or maybe it's possible that it's be a left-over Wintendo
thing? (The last seems unlikely, but I don't dual-boot either.)

Another question is "How can there be routes for ppp0 when ifconfig
showed no PPP interface?"

What are some of the symptoms that cause you to believe you don't
have a viable PPPoE ADSL connection? Not counting the mysterious
eth1 or the missing PPP interface, it appears - from what I do know -
to be a good connection to me.

(If I read adsl-setup correctly then you have a 60 second connect
time-out set, which is not enough time to do much testing.)

Well you are right in some way. The IP of eth0 is never used when
talking to the internet via ADSL.

But my own gateway has a static IP on the eth-interface connected
to the DSL modem and it works fine:-)
Just thought it could be one possible problem, although i don't know
if this IP is really needed.
It's been a while since i set up my gateway, but i have some
thought that this _was_ neccessary.
Anyways, when the distro install assigned DHCP for eth0
and it has no chance to get configured, it may - however -
prevent eth0 from working correctly......weho knows?

What is Wintendo? Sorry, it's abit off-topic, but i never heard of that....

Guess you mixed up some things. This excerpt is from the mentioned
How-To and does not show the configuration in question.
At least i think it's this way.....

I just said an IP address wasn't needed, not that the Ethernet interface
couldn't be assigned an IP address (within reason - i.e, private).

Not for PPPoE ADSL.

Me. PPPoE ADSL uses the PPP interface; the Ethernet interface is
only a convenient means of transport for PPPoE frames that allows
the speed expected of a regular ADSL connection (one that doesn't
use PPPoE). PPPoE is used only because it gives the ISP much more
control over the connection than is possible with regular ADSL.

With regular ADSL the Ethernet interface would have to get an IP address
with DHCP, but the IP address for PPPoE ADSL is the local address of the
PPP interface.

A term I picked up here from another poster. Substitute "dows host" for
"tendo". :-))

Looking back I see what you mean, and I almost certainly *did*
misinterpret it.

So if the OP is reading this, that's how your routing should look
except substitute eth0 for eth1 but you needn't bother to configure an
IP address for eth0. The ifconfig output should show a PPP interface,
usually ppp0, and the local IP address will be your IP address for
the duration of the connection.

So the question "What are some of the symptoms that cause you to
believe you don't have a viable PPPoE ADSL connection?" is moot.
Now that Ralf has pointed out I misread your post, I see that you
don't have a connection. Period.

Look in the logs to see if there is anything related to your connection
attempt(s). Also find out what the message "/usr/bin/tkpppoe: line 24:
exec: wish: not found" means (is wish a shell of some sort?).

I suppose you are aware that you cannot use a 56 kb/s modem for a
PPPoE connection, and that digital lines to your house are required.

Did you do anything about this error? Look at line 24 of your
/usr/bin/tkpppoe and see that it tries to invoke "wish". You don't have
it installed. "wish" is a "Simple windowing shell" provided by the tk
package. The Slackware description for tk:

tk: tk (Tk toolkit for Tcl)

Apparently something detected eth1.
