I'll try to provide all info. So that experts can help me solve the connection problem

1) I'm using ubuntu 4.10 http://www.ubuntulinux.org/ debian based distro

2) the command default in debian me@ubuntu:~ $ pppoe-discovery

Access-Concentrator: net9 Service-Name: net9 Got a cookie: 53 dd 47 9e 6e 39 bc 33 97 a5 11 60 e2 17 71 f2 fc 04 00 00 AC-Ethernet-Address: 00:0c:f1:fc:e6:ef -------------------------------------------------- Access-Concentrator: net9online Service-Name: cable AC-Ethernet-Address: 00:01:0a:11:44:34 --------------------------------------------------

3)adsl-start error ->

pd 2.4.2 started by root, uid 0 ing interface ppp0 nnect: ppp0 <--> /dev/pts/1 mote message: Login incorrect nnection terminated. flush failed: Input/output error it. pd 2.4.2 started by root, uid 0 ing interface ppp0 nnect: ppp0 <--> /dev/pts/1 mote message: Login incorrect nnection terminated. it.

4) username used to connect I tried to connect with both types of usernames. user and user@linuxuser both

5) kernel mode / Normal Mode pppoe connection method -> i dont know how to find this out?

6) tools used to configure pppoe first i used pppoeconf then adsl-setup then edited the pppoe.conf for a-c and service-name

Social and Real world : My ISP cable guy has his router setup in such a way that i can auth the net from web browser http:// 172.50.1.1 but it fails 1/4th of the time.

So on windows xp their so called "engineer" gave me the pacenet dialer and connected me to internet with 1) my username 2) A-C was "net9online" and "service-name" was cable

I called pacenet-call centre and they said they cannot create @linuxuser for me as i use 25kbps plan.

I think connection must work on linux because it works on windows,

I guess the problem might be in these 2 things

1) it sometimes connects with PAP and sometimes CHAP and both methods fail to authenticate, what should i use to connect to server, and how?

2) Problem might also be in kernel or normal mode pppoe , because i dont know the difference

Now I'm on linux and connected to internet by the router way http://172.50.1.1 , but can't hold it for 24*7
