kppp, kinternet or yast?

Hi It's ages since I had to do a dialup installation. My client's ISP (wanadoo, Spain) tells me to use kppp to configure the installation. When I go to install kppp, yast tells me that kinternet is the tool to use. In the days of 6.2 I seem to remember it all being done with Yast. Surely, they write to the same files don't they? Does it matter which I use? Cheers, Steve.
