|One of the great benefits of a domain name that has been registered through a domain name IP address setup is the ability to take advantage of some excellent technologies. The one great technology that is made available by having your domain name come from an IP address is the capability to utilize a service called the Domain Name System (DNS). This service name is used to point websites to their particular servers via the Internet. Here are some things to know about DNS, and how to set up a custom setup for your domain name with a reserved IP address.|
One great thing about using a service such as the DNS is that you are able to use a domain name that has been reserved as one that will be mapped to an IP address. What this means is that whenever someone types in the domain name, it will automatically be interpreted as a series of numbers that are then sent off to the specific server that is specified in the records of the DNS. This in turn will allow the client computer to connect to that server and access the information that is located on that very server.
The DNS works in that it is used as a central database to help with the storage and distribution of information about websites. This is done through a process known as service registration or resourcing. Service registration is a process where a domain name is assigned to a specific entity that will be hosting the website. In order to access this entity and make sure that the information regarding the domain is correctly defined, and all of the proper DNS servers and components are properly set up, the client computer will need to synchronize its time with the DNS server via the Internet.
This process can be easily achieved by using a process known as a "step modify." This step modify is a process where the actual DNS server will rewrite a portion of the DNS zone file so that it will match the new FQDN domain name that has been specified. This means that instead of looking for the information concerning the IP address or the host name, the client computer will have to search for the specific DNS suffix instead. This entire process takes only a few seconds to complete.
In order for this method to work, the DNS server must be restarted after adjusting to the new FQDN domain name. There are a few reasons why this is necessary. If you had a domain name before that was not correctly typed, you will need to retype it into the DNS prompt window before entering the domain name or if there is an error, then the DNS server will return an error message. The resuming of the DNS resolver is only possible with the restart of the DNS server. This method is useful in cases where the primary domain name is also used as the FQDN.
One more possibility of making this work is when the FTP service iptables is configured to allow an interactive users to access the firewall or to allow ICMP echo off packets. If you are not able to change the firewall settings, then you might be able to enable the FTP security group in the Internet service iptables command line interface. The security group will not affect the DNS server but the other services that rely on the DNS server will be affected by the ICMP echo off packet.
If you are able to enable the FTP security group in the Internet service iptables command line interface, then you can set the TCP log forward feature and the FTP security group in the startup configuration for the Linux operating system so that these services will be able to send their traffic through the firewall. The Linux kernels by default do not support the TCP log forward and the only way to make this work is to configure the kernels for the Secure Transport (sts) and ICMP Echo Off (icojacks) protocols. The Linux kernels also have a limited support for the iSCSI protocol and the only protocol that it supports is the iSCSI over Ethernet (oscx). If you have a recent distribution like Red Hat, Fedora or Mandriva, you can enable the TCP log forward and the FTP security group in the netconf for the Linux startup option.
If you are unable to connect to the DNS server using the iSCSI target address or you get an error message, the IPsec module may be loading but the server is not responding. To resolve this problem, update the cache entries for the DNS server and load the modules again. Also verify that the command modem reset is used after rebooting. Another possible configuration error is related to the grammar engine. If you cannot type any text characters in the ';" operator class prompt, the grammar engine might be unable to determine the right character.
