Hello,
I have a DHCP server with this config file:
option domain-name "cassiopeia.ronet";
option domain-name-servers 192.168.0.1;
default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;
ddns-update-style none;
subnet 192.168.0.0 netmask 255.255.0.0 {
range 192.168.0.101 192.168.0.139;
option routers 192.168.0.1;
use-host-decl-names on;
option broadcast-address 192.168.0.255;
filename "pxeboot";
option root-path "192.168.0.1:/mnt/d1/rootfs";
}
I would like the diskless machines to set their hostname automatically.
I have a working named for this. For example:
cassiopeia# host diskless131.ronet
diskless131.ronet has address 192.168.0.131
cassiopeia# host 192.168.0.131
131.0.168.192.in-addr.arpa domain name pointer diskless131.ronet.
cassiopeia#
Of course I can create individual hosts in the dhcp config file and set
their hostnames. But I do not want to create 40 host declarations and
look for the hardware addresses by hand... The clients should be able
to determine their hostnames using a reverse dns lookup, and the set
their hostnames automatically. In the above example: after the machine
got its IP address (192.168.0.131) from the DHCP server, it should set
its hostname to 'diskless131.ronet'.
Sounds easy, but I do not know how to do that. Is it a standard
procedure, or do I need to write a custom script? (Where should I place it?)
Thanks,
Laszlo
