How to connect to internet via DSL (pppoe) using terminal ?

I need to connect to Internet using terminal (because there is a bug in graphical KDE network manager - DSL connection doesn’t work). Using Ubuntu I could do it by using “pppoeconf” command (it asked me login and password). How can I do that in openSUSE ? Or, as an alternative, maybe you know how to handle the bug in KDE ?

I have 25 pop accounts, using pppoe, using KDE. What bug?

BTW, are you using wicked or Network Manager to manage connectivity?
