Hi, Can anyone tell me where I can get a setup and troubleshooting guide for ISC DHCP? My main problem is that when booting up Linux (2.0.34 Red Hat 5.1) I get the message "Using DHCP for eth0 ... failed". Also how do I change my firewall settings. In fact how do I find out what the syntax of the settings are? Thanks, Ishaaq Chandy
