TCP/IP basics
When all of your configuration and zone files have no errors in them, you should be ready to restart the BIND service. Each IP address may then be it's own virtual server and individual domain. Our Goal By the end of this tutorial, we will have a primary DNS server, ns1 , and optionally a secondary DNS server, ns2 , which will serve as a backup. Its sole merits are; it is a convention; it makes sense to its authors. Above the existing options block, create a new ACL block called "trusted".

Some DNS servers provide support for both server roles in a single, "monolithic" program. Others are divided into smaller programs, each implementing a subsystem of the server.

As in the classic Computer Science microkernel debate, the importance and utility of this distinction is hotly debated. The feature matrix in this article does not discuss whether DNS features are provided in a single program or several, so long as those features are provided with the base server package and not with third-party add-on software.

In this overview of operating system support for the discussed DNS server, the following terms indicate the level of support:. From Wikipedia, the free encyclopedia. Consult the axfr-get documentation for further information.

But it is a solution with comparable capabilities. Instead, a zone transfer is needed, after which MaraDNS will act as an authoritative server for that zone. See DNS Slave for further information. Earlier versions could only pass through validation results from their own upstream nameservers.

This supports Recursion control, location aware responses, split-brain deployment, filters etc. It is fully supported in Windows Server The rest might need OS-specific rewrites.

For users of Red Hat 7. The script is to be run with the qualifiers start , stop , restart or status. A restart allows the web server to start again and read the configuration files to pick up any changes.

To have this script invoked upon system boot issue the command chkconfig --add httpd. See Linux Init Process Tutorial for a more complete discussion. Change the default value for ServerName www.

Giving Apache access to the file system: It is prudent to limit Apache's view of the file system to only those directories necessary. This is done with the directory statement. Start by denying access to everything, then grant access to the necessary directories.

Also use SELinux command to set the security context: The Apache web server daemon must be able to read your web pages in order to feed their contents to the network. Use an appropriate umask and file protection. Allow access to web directory: Default permissions on user directory: One may also use groups to control permissions.

See the YoLinux tutorial on managing groups. If the Apache web server can not access the file you will get the error " Forbidden" "You don't have permission to access file-name on this server.

You must allow the web server running as user "apache" to access the directory if it is to display pages held there. The server default for access using the IP address is typically the first domain defined in " conf. This is also the site hackers see when scanning the net via IP addresses. It is often a curse to have a domain starting with the letter "a" as mis-configured servers will lead all hacker traffic to this site.

Thus it is good practice to to generate a default configuration for IP address access. Then reboot the system:. When using SELinux security features, the security context labels must be added so that Apache can read your files. The default security context label used is inherited from the directory for newly created files.

Thus a copy cp must be used and not a move mv when placing files in the content directory. Move does not create a new file and thus the file does not receive the directory security context label. The context labels used for the default Apache directories can be viewed with the command: Assign a security context for web pages: Set the following options: The default SE boolean values are specified in the file: After the Apache configuration files have been edited, restart the httpd daemon: One may assign multiple IP addresses to a single network interface.

See the YoLinux networking tutorial: Each IP address may then be it's own virtual server and individual domain. This usually costs more. The standard name based virtual hosting method above is more popular for this reason.

The Apache web server daemon httpd can be started with the command line option "-f" to specify a unique configuration file for each instance. Configure a unique IP address for each instance of Apache.

Also see the local online Apache configuration manual: Adding web site login and password protection: See the YoLinux tutorial on web site password protection. Scanning the Apache web log files will not provide meaningful statistics unless they are graphed or presented in an easy to read fashion.

The following packages to a good job of presenting site statistics. It will often be used to denote something that needs to be replaced with your own settings or that it should be modified or added to a configuration file.

For example, if you see something like host1. On both servers, edit the bind9 service parameters file:. BIND's configuration consists of multiple files, which are included from the main configuration file, named. These filenames begin with "named" because that is the name of the process that BIND runs. We will start with configuring the options file. Above the existing options block, create a new ACL block called "trusted". This is where we will define list of clients that we will allow recursive DNS queries from i.

Using our example private IP addresses, we will add ns1 , ns2 , host1 , and host2 to our list of trusted clients:. Now that we have our list of trusted DNS clients, we will want to edit the options block. Currently, the start of the block looks like the following:. Below the directory directive, add the highlighted configuration lines and substitute in the proper ns1 IP address so it looks something like this:.

Now save and exit named. The above configuration specifies that only your own servers the "trusted" ones will be able to query your DNS server. Aside from a few comments, the file should be empty. Here, we will specify our forward and reverse zones. Assuming that our private subnet is If your servers span multiple private subnets but are in the same datacenter, be sure to specify an additional zone and zone file for each distinct subnet.

When you are finished adding all of your desired zones, save and exit the named. Now that our zones are specified in BIND, we need to create the corresponding forward and reverse zone files. That is, when the DNS receives a name query, "host1. Let's create the directory where our zone files will reside. According to our named. We will base our forward zone file on the sample db.

Copy it to the proper location with the following commands:. First, you will want to edit the SOA record. Replace the first "localhost" with ns1 's FQDN, then replace "root. Also, every time you edit a zone file, you should increment the serial value before you restart the named process--we will increment it to "3". It should look something like this:. Now delete the three records at the end of the file after the SOA record. If you're not sure which lines to delete, they are marked with a "delete this line" comment above.

At the end of the file, add your nameserver records with the following lines replace the names with your own. Note that the second column specifies that these are "NS" records:. Then add the A records for your hosts that belong in this zone. This includes any server whose name we want to end with ".

Using our example names and private IP addresses, we will add A records for ns1 , ns2 , host1 , and host2 like so:. On ns1 , for each reverse zone specified in the named. We will base our reverse zone file s on the sample db. Copy it to the proper location with the following commands substituting the destination filename so it matches your reverse zone definition:.

Edit the reverse zone file that corresponds to the reverse zone s defined in named. In the same manner as the forward zone file, you will want to edit the SOA record and increment the serial value.

Now delete the two records at the end of the file after the SOA record. Then add PTR records for all of your servers whose IP addresses are on the subnet of the zone file that you are editing. In our example, this includes all of our hosts because they are all on the
