how to run a script at boot time?

Ianculov Vucomir — Sun, 28 Sep 2008 12:23:26 +0000

Your script should be in /etc/init.d/ directory.
Then you have to make a symlink from your run-level directory.
I.e you’re in run-level 5 (multiuser with X)

chmod +x

cp /etc/init.d
ln -s /etc/init.d/ /etc/rc.d/rc5.d/S50
ln -s /etc/init.d/ /etc/rc.d/rc5.d/K50

Assumed that “eth0″ is the interface for network card

IP Address 10.0.0.1

Range: 10.0.0.1 to 10.0.0.30

Subnet Mask: 255.255.255.224

DNS Servers: 193.226.98.1, 193.226.98.2

Domains:r2d2.dositei.ro

Gateway Address: 10.0.0.1

sudo apt-get install dhcp3-server

sudo cp /etc/default/dhcp3-server /etc/default/dhcp3-server_backup

nano /etc/default/dhcp3-server

Find this line

INTERFACES=”"

Replace with the following line

INTERFACES=”eth0″

Save the edited file

sudo cp /etc/dhcp3/dhcpd.conf /etc/dhcp3/dhcpd.conf_backup

rm /etc/dhcpd.conf

nano /etc/dhcp3/dhcpd.conf

copy and paste the code

ddns-update-style none;

log-facility local7;

subnet 10.0.0.0 netmask 255.255.255.224 {
range 10.0.0.1 10.0.0.30;
