We know that no matter how the WAN interface IP address of the youxun router changes after DDNS is configured, Internet users only need to remember our dynamic domain name and can log on to our Intranet server at any time. The configuration method is as follows:1. youxun router advanced settings → DDNS, fill in the account and password of the requested peanut shell, and click to execute2. youxun router pean

serve external users, so that you do not need to set up a DNS server outside of the control, this improves security. Of course, you can also enable DNS Resolvers to be used by both internal and external users. 5. Protect DNS from cache pollution DNS Cache pollution has become a common problem. Most DNS servers can store DNS query results in the cache before they reply to the requesting host. DNS high-speed cache can greatly improve the DNS query performance within your organization. The problem

-4.1.1/DHCPD. conf. Sample/etc/DHCP/DHCPD. conf The DHCPD. conf file contains two parts: global configuration and local configuration: 1. When global configuration conflicts with local configuration, local configuration has a higher priority. 2. Each line in the configuration file must end with a semicolon, because no error is reported when DHCPD is started. You can only check the log file/var/log/message to see if the configuration file is faulty. 3. Local configuration must be included

I used to assign a private server to the rhct Model Tester. Haha, that's good. Now I have taken the CE test again. In fact, it is almost the same. I have already completed the configuration. Now I have time to summarize it. A few days ago, I tried to copy the private server with Chong GE. It was too big. No copies. In fact, the most important thing in the server is DHCP, DNS and an NIS server. Nothing else. It's quite simple to just meet functional requirements. I just need to configure it. DHC

The simplest DHCP Service and the simplest DHCP Service In the past few days, you have prepared to install the linux operating system on the network. Finally, we decided to use pxe + kickstart. After the principles and solutions are completed, the system starts construction and the result is blocked by DHCP. This does not require research on the simplest and most practical DHCP use methods. * Red is required * Note that green * The Blue is the required package for package installation. 1. DHCP

I. Application introductionOur router is embedded with a peanut shell client. After logging on to the peanut shell domain name on the router, we can dynamically associate the WAN port IP address of the router with the IP address of the peanut shell domain name. If you need to access the server under the vro through the Internet, you can use this domain name to access the intranet server by setting the virtual server on the vro and logging on to the peanut shell domain name, you do not need to ca

through the router Win2003 server, and the server has installed a variety of services, such as Web sites, Remote Desktop control, routing management. 2, there is a common computer, the normal access to the line. 3, have a peanut shell account. and set the DDNS. (specifically how to set this section does not speak) Second, enter the routing setup1, forwarding rules-Virtual server-Add new entries > Using interfaces, the default is generally

allow DNS parsers to be used by both internal and external users. 5. Protect DNS from cache contamination DNS cache contamination has become an increasingly common problem. Most DNS servers are able to store DNS query results in the cache before replying to the requesting host. DNS caching can greatly improve DNS query performance within your organization. The problem is that if your DNS server's cache is "contaminated" with a lot of fake DNS information, users may be sent to a malicious site

Cloud Router Tpddns use step one, enter the Setup interface Tpddns is a dynamic domain name resolution service, you can change the IP address and fixed domain name corresponding. Because the router WAN port IP is dynamically changing (for example, under broadband dialing), if the login tpddns, then only need to use the domain name to access the server under the router, regardless of the dynamic change of IP address. This article describes how to use Tpdds. Login Router Management interface, c

" table. Select the "Prevent cache pollution" option and restart the DNS server. 6. Make ddns use only secure connections Many DNS servers accept dynamic updates. The Dynamic Update feature enables these DNS servers to record DHCP-enabled hostsHost Name and IP address. DDNS can greatly reduce the management cost of the DNS administrator. Otherwise, the Administrator must manually configure the DNS resource

. "Peanut shells" support common telephone lines, ISDN, XDSL, cable TV networks, twisted pair wires, and other access service lines that can provide real Internet IP addresses, regardless of whether the IP address obtained by the connection is dynamic or static. Peanut shell is a free Desktop Domain Name management, dynamic domain name resolution (ddns) and other functions as one of the client software. The peanut shell client provides users with

Wake on the network, WOL. Simply speaking, the computer is in the shutdown state, you can send special packets to the network card via the Internet, the network card after receiving the specified package, turn on the computer. WOL requires hardware to support this feature, the current market mainstream Ethernet card support WOL function, and wireless network card to find a number of not found to support the function of the wireless card.I have successfully implemented the wake on LAN function at
