xDSL Setup under Fedora 3

[Kalb]

Hi everyone. I really hope, someone can help me out here, as I can't seem to get my DSL Connection to work under Fedora (and it does work fine under WinXP).
First off, do I have to setup my Ethernet card with the connection wizard, and does it (the eth0 connection) have to activated or deavtivated for the DSL connection to work?
I tried the following with my eth0 connection avitavated and deavtvated, but got the same results:
I configured my DSL Connection with the connection wizard, but whenever I press "activate" it takes about 40 seonds before I get this error:
/sbin/adsl-start: line 217: 3993 Terminated $Connect "$@" >/dev/null 2>&1
Now I'm assuming this cryptic looking line, basically means, that my connection timed out, right?
Because even when I pull my cable from the ethernet card (the cable between ethernet card and dsl modem that is) I get the same error!
The next thing I tried were these steps:

Setting it up

* Run ‘adsl-setup’ and answer all the questions.
* When asked for your login, enter
1und1/1234-56@online.de
where 1234-56 is your 1&1 online account number. Don’t forget to append ‘@online.de’!
* When asked for the DNS server (domain name server), enter
server
* When asked for your Ethernet connection, enter eth0 if your DSL Modem is connected to the first ethernet card.
* Make sure you do not have a default route configured for your ethernet card.
* Make sure you do not have a name server configured for your ethernet card - unless your name server is actually working and connected to the internet. But if it was, why would you want to set up the DSL connection.

Establishing a connection

* To connect to the internet, type
/sbin/ifup ppp0
* To terminate the connection, type
/sbin/ifdown ppp0

I don't have 1 & 1 as my ISP, but T-Online. So the only thing that I did different was the login name part.
But still, the same error occured.
Oh and the worst part is yet to come:
Each (!!!) time I tried to connect to the net with one of the methods above, my DSL stopped working under WinXP too! I called my provider, and was told that my account was blocked, because I had supposedly entered the wrong password 9 times, which is completely impossible, since I definately entered it right and I only tried to connect twice, then went back to WinXP and the DSL connection was already not working anymore. So I can't even just try some things out, to get the DSL connection working under Fedora, because each time I do, I have to call my provider afterwards and make him unblock my account.

So please, I really need help (and yes, I am new to linux, so please try to be specific). I just don't understand why it doesn't work, and I certainly don't understand why these timed out connection attempts under Linux seem to mess my DSL Connection up :(

I have yahoo sbc dsl and here is the how to. (http://www.fedoraforum.org/forum/showthread.php?t=19352)

I don't want to seem rude or anything, but did you read my post? I already tried these "conventional" HOW-TOs to set up my DSL connection. But as I said, it just doen't work.

[imdeemvp]

Did you enter the needed info and did you see the link at the end of how to that shows details of the setup?

[Kalb]

Yeah I did, but I already tried the steps you explained and got the described errors (meaning I got a time-out or whatever under Fedora and then the DSL connection wouldn't work under WinXP anymore until I called my provider)
the only part I did different, was the DNS part, there I just entered "server" when the adsl-setup asked me about it, and left it blank when I used the connection wizard. But as far as I know I don't have to enter DNS manually for my provider (I don't have to in WinXP either).
And I have a Knoppix CD here, and when I boot with that, and use the dsl wizard that comes with knoppix, it works perfectly fine! I just don't get it, why it will not work under Fedora...

Just a quick thought, I know it might sound silly but seeing as your ISP is blocking your account claiming that the password has been entered incorrectly 9 times. When you've typed your password into adsl-setup does your password contain any numbers? If so were you typing them in from the numeric pad? Maybe numlock was off because I know that numlock doesnt automatically turn on when you boot. Try tying it just in a console to see if you get the expected output.

[Kalb]

It does contain numbers, but I didn't use the numpad to enter them. And besides, I only tried to connect twice and my ISP already blocked me claiming I entered it 9 times.
Man I'm telling you, this is really driving me nuts.

[imdeemvp]

During installation did you enable selinux and what are your firewall settings? system-config-securityleve

[Kalb]

OK, under Firewall Options it says:
Enable Firewall
Trusted services: (the following are checked) FTP, SSH
Trusted Devices: eth0 (is checked); sit0 (NOT checked)

SELinux:
Enabled
Enforcing Current: Enforcing
Pilicy Type: targeted
Under Apache everything is checked
Under Name service nothing is checked
under NIS there is one thing and that is checked
under transition nothing is checked

So should I modify any of these settings?

I didn't have a chance to try this out yet, but a friend of mine came up with the following:

As I said, when I try to connect with my DSL account, my provider claims I entered the wrong password 9 times (although I entered it correctly) BUT my password contrains special characters (a German Umlaut). Maybe linux doesn't know how to encrypt that, because passwords are generally transfered encrypted. So maybe it encrypts it wrong, and that's why.
What do you guys think? Is that possible? (I don't wanna try it just yet, cause you know, fear of getting my account blocked for 24 hours again :) So I'd like some backup on that suggestion before I try it out.)
