allowsindividual devices on an IP network to get their own networkconfiguration information (IP address, subnetmask, broadcast address, etc .) from a DHCP server. the overall purpose of DHCP is to make iteasier to administer a large network. (4/4): dhcp-devel-4.1.1-53.P1.el6.centos.x86_64.rpm | 158 kB # Header files and API documentation for using the isc dhcp libraries. thelibdhcpctl and libomapi static libraries are also encoded in this package.
Configuration process
1. Check the dhcpd. conf
is not modified, an error will still be reported when dhcpd is started.
You can refer to another user's dhcpd. conf file for modification.
Because I am working on a vro, there are many NICs, and the parameters are complicated, so I will not post them.
Next, paste it to someone else. This is easier to understand:
Ddns-update-style interim; # configure to use the transitional DHCP-DNS interactive update mode. Ignore client-updates; # ignore client upd
7. Configure the DHCP server and dhcp server for two different subnets.
The environment is as follows: (ensure that the two subnets can be pinged to each other before reference)
Vm1 192.168.170.3 VMnet8 (NAT Mode)
Virtual Machine vm2 192.168.155.3 VMnet1 (host mode only)
Virtual Machine gate 192.168.170.4 (eth1) VMnet8 (NAT Mode)
192.168.155.4 (eth0) VMnet1 (host mode only)First: configure the DHCP server on the gateway gate
(Eth0) provides IP Address Allocation service for the 192.168.155.0/24
IP address, such as "192.168.1.254". When the setting takes effect, the router's LAN IP address becomes "192.168.1.254", and the router is set up to be accessed via IP connection.
Route to the Internet
On other computers, set the gateway as the host router IP address, set up DNS or use DHCP to freely access the Internet. U disk Router is very powerful, can support the 3322com DDNS, support peanut shell DDNS

Install the DHCP service in Linux-Linux Enterprise Application-Linux server application information. For details, refer to the following section. 1. Create a DHCP server configuration file
You can use Redhat Linux 9.0 to install it with its own rpm package. After the installation is complete, the DHCP port supervisor dhcpd configuration file is the dhcpd. conf file in the/etc directory. Create the/etc/dhcpd. conf file manually. /Etc/dhcpd. conf usually includes three parts: parameters, declarat

When the Active Directory is updated between "bridgehead" servers, it is automatically compressed. The bridgehead server is automatically generated on the local LAN server. When the Active Directory is updated using the WAN link, the bridgehead server of each LAN will communicate with other bridgehea

If you cannot find your configuration file, you can use the search command we have learned, locate filename for search,
After finding this file, Let's first look at the template configuration.
For convenience, I used the cat command to import the configuration file to a text file, and then I got win. The template configuration file is as follows:

You can enable DHCP in "network address server settings (DHCP)" below.In addition, many ADSL modem also support web management. The default value of their IP addresses is often 192.168.1.1, which may conflict with the LP address of the router, the router cannot be installed and used. Therefore, we must change the lan ip address of the router. In the "Network Settings/router IP" section, change "local IP Address" to

The first step in configuring the DHCP server is to create a configuration file for storing the customer's network information. Global options can be declared for all customers, and optional options can be declared for each customer system.
This configuration file can be simply formatted using any additional tab or blank lines. The keywor

Today, if you want to allow your colleagues to access the version library of the company's intranet server at home or outside, you need to modify the configuration.
Because the Office uses routers to access the Internet, the public IP address will change constantly, So I first thought of a peanut shel
