Help on DHCP
Hi All,



I am trying to configure dhcp server on a linux host with eth0:1 which is using 192.168.1.10

I also want to restrict my DHCP client to just one Host adcnew222.


DHCP Server Host name - adcnew111

DHCP client name - adcnew222

My conf file is as follows on dhcp server :




In /etc/dhcpd.conf

=======

ddns-update-style interim;
ignore client-updates;

interface eth0:1;

subnet 192.168.1.0 netmask 255.255.255.0 {


range 192.168.1.128 192.168.1.254; # Range of IP addresses to be issued to DHCP clients
option subnet-mask 255.255.255.0; # Default subnet mask to be used by DHCP clients
option broadcast-address 192.168.1.255; # Default broadcastaddress to be used by DHCP clients
option routers 192.168.1.10; # Default gateway to be used by DHCP clients
option domain-name "us.domain.com";
option domain-name-servers 144.20.110.70, 138.22.202.15, 130.53.242.41; # Default DNS to be used by DHCP clients


default-lease-time 21600;
max-lease-time 43200;



host adcnew222 {
adcnew222.us.oracle.com;
hardware ethernet 00:16:3E:48:E1:3E;

}


}

       You can perform the following tasks using dhcpmgr:

       Configure DHCP service

           Use dhcpmgr to configure the DHCP daemon as a DHCP server, and select the data store to use for storing network configuration tables..

       Configure BOOTP relay service

           Use dhcpmgr to configure the DHCP daemon as a BOOTP relay.

       Manage DHCP or BOOTP relay service

           Use dhcpmgr to start, stop, enable, disable or unconfigure the DHCP service or BOOTP relay service, or change DHCP server parameters.

       Manage DHCP addresses

           Use dhcpmgr to add, modify, or delete IP addresses leased by the DHCP service.

       Manage DHCP macros

           Use dhcpmgr to add, modify or delete macros used to supply configuration parameters to DHCP clients.

           store.

       Move DHCP data to another server

           Use dhcpmgr to export data from one Solaris DHCP server and import data onto another Solaris DHCP server.
