Author: User

In the past, we have learned the basic content of the DHCP service, and we have also learned how to configure DHCP servers in Windows. Next we will mainly explain the configuration of the Linux DHCP server.

Linux DHCP server configuration

1. Install the Linux DHCP service package

RHEL4 fourth disc, dhcp-3.0.1-12_EL.i386.rpm

Mount/dev/cdrom/media/cdrom/

Install the DHCP package

 
 
  1. rpm -ivh /media/cdrom/RedHat/RPMS/dhcp-3.0.1-12_EL.i386.rpm 

2. dhcp. conf configuration file parsing

Copy the sample file to/etc/

 
 
  1. cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf 

Linux DHCP server configuration instance

 
 
  1. Ddns-update-style interim;  
  2. Ignore client-updates;  
  3. Subnet  10.0.0.0  netmask  255.0.0.0  {          
  4. # --- default gateway  
  5. option routers                   “10.0.0.0.1”;  
  6. option subnet-mask              “255.0.0.0”;  
  7. #       option nis-domain                “domain.org”;  
  8. #       option domain-name              "domain.org";  
  9. #       option domain-name-servers       10.0.0.1;  
  10. #       option time-offset              -18000; # Eastern Standard Time  
  11. #       option ntp-servers              192.168.1.1;  
  12. #       option netbios-name-servers     192.168.1.1;  
  13. # --- Selects point-to-point node (default is hybrid). Don't change this unless  
  14. # -- you understand Netbios very well  
  15. #       option netbios-node-type 2;   
  16. range dynamic-bootp 10.0.0.100 10.0.0.200;  
  17. default-lease-time 21600;  
  18. max-lease-time 43200;  
  19. "/etc/dhcpd.conf" 31L, 852C          1,1            
  20. # we want the nameserver to appear at a fixed address  
  21. host ns {  
  22. next-server marvin.redhat.com;  
  23. hardware ethernet 12:34:56:78:AB:CD;  
  24. fixed-address 207.175.42.254;  
  25. }  

3. configuration files are required for multiple network interfaces of the Linux DHCP server.

 
 
  1. /Etc/sysconfig/dhcpd
  2. DHCPDARGS = [network interface]

4. Start the dhcpd Service

 
 
  1. Service dhcpd start 

5. Configure the client to dynamically obtain the IP address
