[newbie] Dhcp problems

[Rick Nyhan]

i have a teensy problem, in order to configure my cable modem, i have to go through a dhcp *not a problem dynamic ips work* but the command i have to run in order for it to send out my host name cx618-b is in this command /sbin/dhcpcd -d -I cx618-b   now the problem... at bootup the process of eth0 just hangs until it fails, then i have to login as root and run that command line, get my ip sign out and login under my account, how would i correct the startup script to send just that command?   Peter
