Yes now if you are connecting from India then you shoule have BSNL Dataone, Tata, or reliance
I am describing you with graphical setup approach and the CUI.
Code:
GRAPHICAL
1]Launch system-config-network from KMenu->Settings->Network or by simply typing in "system-config-network" in konsole
2]Select New and then Select xDSL Connection then click Forward
3]If you have multiple card then select the Network card in the list
4]Then Type in the Provider Name (the name of your service provider is sot critical data)
5]Type in the Id and the Password and click Forward and your connection will be created.
6]Save the new connection and save it
CUI
1]Launch Konsole
2]get superuser "su" and then password
3]/sbin/pppoe-setup
4]Enter The Login name your service provider provided you with
5]Select the interface i.e the Network card (if you have more than one)
Press enter if it shows that the default is the only one card you have
or type in the card name in the system like eth0 , eth1 etc.
6]Enter the demand value "no". (by default it is "no")
7]When the DNS Server IP is requested from you enter "server" in lowercase (small letters)
Because you have dynamic IP Configuration and your service provider will provide you with a DNS Server
8]Enter the Password the service provider provided you. Confirm the password in the next line when prompted to
9]You will then be prompted that if you want , that the other users other than the root user can use this connection, enter "yes" to login without root access.
10]Enter Firewall settings as per your need, i would say you should enter "1" (You will be given three levels 1, 2, 3 details would be written beside them)
11]You will be asked then , if you wand to bring up this connection when you boot ,
enter "no" , if you would like to manually connect, (as all do when using this type of connection)
12]Check the details you entered in the list displayed then confirm with enterinh "y"
To Connect
1]Launch system-config-network and select the xDSL connection you created now, and click Activate
else
2]Launch konsole then type in "/sbin/ifup provname"
where the "provname" is the provider name yuo entered (case sensitive)
To Disconnect
1]Launch system-config-network and select the xDSL connection you created now, and click Deactivate
else
2]Launch konsole then type in "/sbin/ifdown provname"
where the "provname" is the provider name yuo entered (case sensitive)
Note one thing you may use any way to create connection but the both ways do the same work and you may connect in any way you like ( i mean there is no restrictions that if you created the connection with GUI then you need you ust the GUI way to connect, you can use both)you will also notice that a new xDSL connection has appeared in the system-config-network list
Please also note that then using the CUI Command line way the connection which will be created, the name will be "ppp0" by default
to connect do /sbin/ifup ppp0 (this the service provider field actually)
Configure the firewall properly.
Be shure your LAN Card works by entering command
"/sbin/ifconfig"
If you can see your network device name for example "eth0" in the list presented
and also can see the Hardware MAC Address Then all is ok.
If still dollowing thease you cannot connect to the net , please post.
