That may give you some better ideas as to what's going on. You should also have a look at the DHCP server's logs. My guess is that you really don't have the MAC address of the machine registered with the DHCP server (it's easy to make a mistake with six hex octets) or that your iptables is blocking it. DHCP uses UDP port 68 (sometimes TCP port 68), so make sure iptables isn't blocking it (iptables is started before the network interfaces are brought up). If you need some rules for iptables to allow DHCP, here they are: -A INPUT -p tcp -m tcp --dport 68 -j ACCEPT -A INPUT -p udp -m udp --dport 68 -j ACCEPT Stick them somewhere appropriate in your /etc/sysconfig/iptables file and restart iptables. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - grep me no patterns and I'll tell you no lines - ----------------------------------------------------------------------
