When setting up a slip interface with linuxconf under RH6.0, linuxconf creates /etc/sysconfig/network-scripts/chat-$DEVICE. Unfortunately, RedHat's network scripts (ifup-sl) expect to find a dip script (/etc/sysconfig/network-scripts/dip-$DEVICE). Workaround: use control-panel (netcfg) to set up network interfaces.
