I am new to networking. I have a FC16 machine that has two network interfaces em1 and p3p1. The em1 is connected to the outside world. The p3p1 is the interface that I want to connect to my embedded board. I have configured p3p1 to a static ip address - here are the details. The problem is that the embedded device is not able to acquire the IP address sent out by the DHCP server. I cannot see the Discover, offer, request, and acknowledge messages also. What could be the issue here?
gvim ifcg-p3p1
HWADDR=cc:b2:55:ba:b6:a4
BOOTPROTO=none
#IPADDR=10.0.0.1
#NETMASK=255.255.255.0
#NETWORK=10.0.0.0
ONBOOT=yes
NM_CONTROLLED=no
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
IPADDR=10.0.0.10
NETMASK=255.255.255.0
GATEWAY=10.0.0.1
PREFIX=24
Now, on ifconfig, it shows me this.
p3p1 Link encap:Ethernet HWaddr CC:B2:55:BA:B6:A4
inet addr:10.0.0.10 Bcast:10.0.0.255 Mask:255.255.255.0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I have given the extra parameters on the dhcp config file.
gvim /etc/sysconfig/dhcpd
DHCPDARGS="p3p1"
Now, this is the dhcpd.conf file.
# gvim /etc/dhcp/dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see dhcpd.conf(5) man page
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
ddns-update-style none;
subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.1 10.0.0.14 ;
}
However, on running the dhcp server-
as
#sudo service dhcpd restart
Redirecting to /bin/systemctl restart dhcpd.service
I see that there is no DORA - Discover, Offer, Request, Ack. procedure.
