need help with network installation


I am trying a network installation of openSUSE 11. My connection is a PPPoE
connection. It needs me to login. During the install, by denying automatic
configuration by dhcp, I get into manual configuration where I set the IP
address, subnet mask and default gateway. However, I can’t find the option
for login. Help me in this regard.

Thank you.

I tried to get clues by pressing Alt+F3 and it showed me that the following was being tried.
url mount http://<myusername><mypassword>@<IP of my ISP>/

Any idea how I can set it right?
