Hi,
I am new to Linux. Just installed Ubuntu 10.04 few days back. The problem I am having is not able to connect to internet. Mine is direct cable connection using CAT5 cable terminted to my ethernet card. and I connect to the net using a dial-up connection. I think other end of the cable is terminated to a common switch.
I have tried searching it over net. The only thing I could figure out is that I have to do some configuration on pppoe (am i right?)

Are there any commands I have to enter or anything like we used to do in windows ?

Please help. Will be really thankful.

Piyush.

Greetingz!

Okay, I'm not exactly sure what kind of Internet connection you have. You mention "dial-up" and "Cat5" in the same sentance, so I'm assuming you have some sort of ADSL setup.
If that's the case, then I would suggest you look at how your Windows configuration is setup;

1) Do you have to launch any sort of custom software to connect to the Internet?
If so, then it's probably a PPPoE connection manager. There are many ways to setup a PPPoE connection, however I'm not an Ubuntu user myself.
It would be a good idea to ground yourself in the basics first, so hit up the Wikipedia article on PPPoE first.

2) If you don't need to launch a custom application to connect to the Internet, then check you're web browser's settings.
There's a chance it has a connection setup to use by default (I know it's possible to do that with Internet Explorer)

On the flip side, there may be a way to configure your ADSL modem to "listen" for a connection request, and do all the connection-building for you.

One more tip; Ubuntu seems to have a wizard or GUI setup for almost *everything*. Be sure to check the documentation for the Operating System.

Good Luck!

pppoeconf is a commandline tool (available in at least 6.06 and 8.04; possible in later ubuntu versions as well)

If it's about pppoe, that's the program that your looking for; probably needs root permissions, so you need to use sudo.

It will scan the network ports for a modem and allow you to configure the required information.

Thanks Xeleema, ronlau9 and Wim Sturkenboom,

I am not using any third party software or modem for connection. I connect using a dial up connection made by my ISP guy; putting ISP server name in dialling number.

I guess it is something to do with pppoeconf. I have tried configuring it and following the steps to create a connection. But while connecting I get the error of CHAP authetication failed. Is it something to do with chap-secret file?

Also, in windows, apart from username and paasword, there was field for dialling number. I used to put ISP server name there. I couldn't find such field here in linux. I think i need to configure my ISP server name somewhere.

Please help. Thanks for the support.

Ah! This is starting to sound more and more like a PPPoE setup!
Which is strange, because you mentioned that you think the other end of the Cat5 termintes at a switch. Connected to that switch should be an ADSL modem.

Is this a "Home" or "Office" setup? I would really suggest that you try to map-out and get a feel for the layout of your networking infrastructure. Mainly because, if there's an ADSL modem somewhere, and you have the only computer, then you should be A-OK.

Just to be on the safe side, pop open a command prompt and run 'ifconfig -a' and tell us the names of the NICs you have (eth0, eth1, lo, sip0, etc) and what IPs they have.

Note: if you get "command not found", then switch to root. If you still get "command not found" run 'updatedb && locate ifconfig | grep bin'


Hell, if you get REALLY stuck, read this.

So finally, After a week's effort, I could solve my problem. Following are things I did.

1. Run pppoeconf and followed the steps.
2. pppoe-discovery to get my ISP's ACNAME & SERVICENAME
3. pppoe-setup and followed the steps.
During this setup it gave the error of missing pppoe.conf file.
4. I downloaded a sample pppoe.conf file from a web site
5. again pppoe-setup and followed the steps.
6. Edit pppoe.conf to enter my ISP's ACNAME & SERVICENAME
7. pppoe-start to start my connection.
8. pppoe-stop to stop my connections.

So, to find out these 8 step, it took 8 days. But, now I have a smile that it is up and working.

Thank you all for the support.

Congratulations; not bad, one step per day on average ;-)
