Private IP Addresses - 0 views

  • IP Helper-Address The ip helper-address command is a static command that is configured on a router interface to direct broadcasts to desired destinations within your internetwork. Configuring the ip helper-address command is simple and straightforward. You just have to be aware of which interface the broadcasts are being received on and where you want to forward these broadcasts to. For example, in Figure 7.21, the 2501A router Ethernet0 interface receives a Dynamic Host Configuration Protocol (DHCP) client request from HostA, which is a broadcast looking for a DHCP server. Figure 7.21: An ip helper-address single server example The 2501A router needs to be configured as follows: 2501A#config t 2501A(config)#interface ethernet0 2501A(config-if)#ip helper-address 172.16.30.2 The 2501A router now receives the DHCP client broadcast and forwards this broadcast to the DHCP server, which then provides a DHCP address to the client. If you have more than one DHCP server for redundancy purposes, as shown in Figure 7.22, you can configure a subnet broadcast address instead of a single server address. Figure 7.22: An ip helper-address multiple server example The 2501A router would be configured as follows: 2501A#config t 2501A(config)#interface ethernet0 2501A(config-if)#ip helper-address 172.16.30.255 The 2501 router now takes a DHCP client broadcast and sends this to any DHCP server on the 172.16.30.0 network. Remember that when you enable the ip helper-address command, you are forwarding more than just DHCP requests. Let’s discuss all the ports that are being forwarded

    This website is all about the software package Drupal with quick links on everything from how to get started to support forums. This will be very useful for the individual project as it lists a whole range of different types of websites that it supports so will give a better idea on how the configuration should be done.

Linux DHCP Server, Dynamic IP, DHCP how to, sytem administration, linux system, linux d... - 0 views

  • The entire DHCP server configuration consists of three stages. If you are running a firewall (iptables), allow the DHCP You must configure the /etc/dhcpd.conf A running dhcpd daemon (which can be started at boot time)
  • Even though DHCP gives out IP address dynamically, it also has the ability to reserve an IP address for a certain computer. In this sense it's almost as if the client computer has a static IP even though it uses DHCP to get it. This is useful if you want to be able to put entries in your /etc/hosts file and not have to worry about the entry becoming invalid over time.  The first thing we must do is to specify a name for the computer as a helpful identifier
