Hello, I configured my isdn subsystem to activate the ippp0 interface at boot time. That is in /etc/sysconfig/network-scripts/ifcfg-ippp0 I have a ONBOOT="yes". But this interface is NOT started at boot time. I guess there's an error in /etc/rc.d/init.d/network: In line 38 egrep -v 'ifcfg-ippp[0-9]+$' | \ the -v is wrong. Best regards ~Andreas Simon
