Installing DHCP (uDHCPd) on TTYLinux

Under TTYLinux, the BusyBox provides most of the services I needed except DHCP server. After much research, I managed to have it install.
Stuff needed :
1. BusyBox binary package – [LINK]
2. TTYLinux – [LINK]
1. Boot into TTYLinux
2. Download the BusyBox into the TTYLinux - link
# wget http://busybox.net/downloads/binaries/latest/busybox-x86_64
3. Make it executable
# chmod +x busybox-x86_64
4. Install BusyBox
# ./busybox-x86_64 --install
5. Verify
# ls -l /usr/sbin --> notice udhcpd date/time ?
6. Copy service script under the /etc/rc.d/init.d folder (thttpd)
# cp /etc/rc.d/init.d/thttpd /etc/rc.d/init.d/udhcpd
# sed -i 's/thttpd/udhcpd/g' udhcpd
# sed -i 's/httpd/dhcpd/g' udhcpd
# sed -i 's/thttp/dhcpd/g' udhcpd
# nano /etc/rc.d/init.d/udhcpd
* comment out the portion for
     * addgroup
     * under start() -> comment out doGroupCheck
     ! load_proc ${UDHCPD} -fS /etc/udhcpd.conf $
# service udhcpd [start/stop/restart/status]
make sure interface facing the LAN has the an IP interface from the subnet.
# ifconfig --> verify
# ifconfig eth0 10.0.0.1 netmask 255.255.255.0
# ifconfig eth0 up
make it permanent at /etc/sysconfig/network-scripts/ifcfg-eth0
ENABLE=yes
IPADDRESS=10.0.0.1
CIDRLEN=24
NETWORK=10.0.0.0
NETMASK=255.255.255.0
BROADCAST=10.0.0.255
DHCP=no
! Restart the networking service to refresh the settings.# service network restart
7. Create the UDHCPD configuration file
# touch /etc/udhcpd.conf
Content of the /etc/udhcpd.conf
========================================
# Sample udhcpd configuration file (/etc/udhcpd.conf)
# The start and end of the IP lease block
start            10.0.0.20   
end                10.0.0.254   
# The interface that udhcpd will use
interface    eth0        #default: eth0
option    subnet    255.255.255.0
option    router    10.0.0.1
option    dns            10.0.0.2
========================================
8. Create the UDHCPD lease file
Add the leases file
# touch /var/lib/misc/udhcpd.leases
9. Allow the UDP port 67 and 68
# nano /etc/firewall.conf
    add under [UDP] 67 and 68
   
10. Restart the firewall services
# service firewall restart
Voila!
