F15: How to set up an xDSL connection?

[sguazt]

Hello,

Until F14, I used to create a ADSL connectiont with system-config-network.
Now in F15:
* The system-config-network application seems to have lost its
"power": no GUI and not able to create such a connection
* I've looked at the GNOME3 default "network settings" but the only
connections that I can create are: Wired, Wireless, Mobile broadband,
Network proxy-

Finally, I found the application 'pppoe-setup' which did the work...
even if now when I do "ifup ppp0" I get the error:
  './network-functions: line 94:
/etc/sysconfig/network-scripts/ifcfg-Alice: Permission denied'

So, what is the right tool to use?

Thank you very much!

Best,
