Hi All, I've just configured my Fedora installation to connect to my ISP thru ISDN Connection. I dialup by activating the ippp0 interface by the Network Device interface tool. It dialup normally and connect successfully to my ISP but the ippp0 interface remains in "Inactive" state. I can't disconnect thru the same tool: now I use ifconfig ippp0 down. It's not a problem unless, by typing "ifconfig -a" by the Terminal (in XFree), It shows alway my ippp0 interface up as if it wasn't brought down. Switching in textmode Console, the same command (ifconfig -a) doesn't show the ippp0 interface. Does Terminal "cache" the command output ? Why doesn't "Network Interface" tool recognize my ISDN interface up ? Thanks, Igor.
