Here's a example from redhat's script that configures your networking. In my case it is in the file, /etc/sysconfig/network/network-scripts/ifcfg-eth0 you can edit it manually, but GUI's like netcfg (prior to rh7) or redhat-config-network in rh7+ will do this for you. Your details may differ. Also sure you don't have a GATEWAY set in /etc/sysconfig/network/network , since DHCP will set that for you:
DEVICE=eth0 <-- eth0 or eth1 ..... whichever BOOTPROTO=dhcp <-- Comcast appears to use standard DHCP BROADCAST= IPADDR= NETMASK= NETWORK= ONBOOT=yes <-- pick yes or no GATEWAY= <-- make sure this is blank (check you ../network file also) TYPE=Ethernet FORWARD_IPV4=yes <-- only if you have a local LAN USERCTL=no <-- that's up to you PEERDNS=yes <-- will set DNS for you DHCP_HOSTNAME=cc12345-a <-- you need to know your "CC" hostnameIf you like totally manual setup, the following command would do that: (and this would be distribution independant)
dhcpd -h cc12345-a eth0
You probably also need to know a few mail and news server names:
mail: mail.comcast.net (POP3) [some claim you may need e.g. mail.nrockv01.md.comcast.net] smtp: smtp.comcast.net news: news.md.comcast.giganews.com (i think)
