Hello,

Hi,
I'm planning to install an image of Debian to a number of computers. Each of
these computers will have the same configuration except the hostname and the
IP address. The IP configuration has to be static. I can't use a DHCP
server.
QUESTION; Is there a way to assign a hostname and a static IP address at
boot time depending on the MAC address of the computer's network interface
card?
If you know which macs you will have, you can make an init script
which generate /etc/network/interface and /etc/hostname and /etc/hosts
the first boot and then remove itself.
Imagine:
$ cat /etc/machines
mac1 ip1 hostname1
....
macN ipN hostname N
$ cat /etc/init.d/10setnetworkonlyfirstboot
#!/bin/bash
mymac=$(ip add show dev eth0 | awk '/ether/ {print $2}')
myhost=$(awk "/$mymac/ {print \$3}")
myip=$(awk "/$mymac/ {print \$2}")
sed -i "s/IP/$myip" /etc/network/interfaces # and probably some
changes in /etc/hosts
sed -i "s/HOSTNAME/$myhost" /etc/hostname # and probably some changes
in /etc/hosts
rm -f /etc/init.d/10setnetworkonlyfirstboot
$ cat /etc/network/interfaces
auto eth0
iface eth0 inet static
address IP
network xxx
gateway yyy
$ cat /etc/hostname
HOSTNAME
Do you think this is a good approach ? It is not very elegant, but
maybe it works.
Regards,
