DNS: MX Records Explained |
vote
|
|
This article is a nice introduction to the DNS MX record and its usage.
The MX record shows that all emails @ mydomain.com should be routed to the mail server at mydomain.com. The DNS record shows that mydomain.com is located at 216.34.94.184. This means that email meant for liz@mydomain.com will be routed to the email server at 216.34.94.184. This finishes the task of the MX record. The email server on that server(say sendmail) then takes over, collects the email and then proceeds to distribute it to the user ``liz''. read more... |

Tutorial: Install MyDNS-NG, MyDNSConfig on Debian |
vote
|
|
| This tutorial will describe how to install and configure MyDNS-NG and MyDNSConfig 3 on Debian Squeeze. MyDNS-NG is a DNS server that uses a MySQL database as backend instead of configuration files. The advantage is that MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted. A secondary nameserver can be easily set up by installing a second instance of MyDNS that accesses the same database or, to be more redundant, uses the MySQL master / slave replication features to replicate the data to the secondary nameserver. read more... |

| What is djbDNS? And why do we use djbDNS? There is a new point of view to serve the dns service - each of the dns server functions is a separate service, like authority, cache, forward and so on. The other difference is the daemon-tools which will rapidly restart services to prevent zombies. read more... |

Tutorial: Install a Bind9 Master / Slave DNS System |
vote
|
|
| In this tutorial two Bind DNS servers will be installed, one as the master and the other as a slave server. For security reasons Bind9 will be chrooted in its own jail. Using two servers for a domain is a commonly used setup and in order to host your own domain you are required to have at least two domain servers. If one breaks, the other can continue to serve your domain. read more... |

Tutorial: Setting Up A DNS Server |

An introduction to the Domain Name Service and how to use it..
There are a couple of ``gotchas'' that normally are avoided with name lookups that are often seen when setting up reverse zones. Before you go on you need reverse lookups of your machines working on your own nameserver. If it isn't go back and fix it before continuing.
I will discuss two failures of reverse lookups as seen from outside your network... read more... |

Dynamic DNS on Linux |
vote
|
|
Need to connect remotely to your Linux system -- but you don't have a static IP address?
The solution is to choose your own hostname for your PC, set up a record for it with a dynamic DNS service provider, and set up your PC to check its own IP address regularly and send an update message to the dynamic DNS server when it changes. Then you can SSH to myhost.unclenatesdomain.org and be assured it will reach your PC.
Choosing which dynamic DNS provider to go with can be as confusing as picking a Web hosting provider... read more... |

MyDNSConfig 1.0: Manage DNS through a web interface |
vote
|
|
MyDNSConfig is a free web-interface written in PHP that allows to administrate/create/delete DNS records easily. All data is stored in a MySQL database, and this MySQL database is used by the MyDNS name server to retrieve the DNS records which means: no zone files, no server reloads.
The software lets you manage the following record types:- A records
- ALIAS records
- CNAME records
- HINFO records
- MX records
- NS records
- PTR records (for reverse lookups)
- RP records
- SRV records
- TXT records (and therefore also SPF records)
MyDNSConfig has just been initially released in version 1.0.0 under a BSD license and is maintained by the ISPConfig (http://www.ispconfig.org) development team.
The release of the software is accompanied by a HowtoForge tutorial that describes how to install and configure the MyDNS nameserver and MyDNSConfig: http://www.howtoforge.com/mydns_name_server
MyDNSConfig can be downloaded from http://www.mydnsconfig.org. read more... |

Tutorial: DjbDNS on Ubuntu Server 8.04 |

|
|
DjbDNS is a collection of Domain Name System tools. It includes software for all the fundamental DNS operations. This tutorial shows how to set it up on an Ubuntu 8.04 AMD64 server.
When a browser wants to contact www.hotwired.com, it first asks a DNS cache, such as djbdns's dnscache, to find the IP address of www.hotwired.com. Internet service providers run dnscache to find IP addresses requested by their customers. If you're running a home computer or a workstation, you can run your own dnscache to speed up your web browsing. read more... |

Tutorial: A MySQL based DNS Server: MyDNS |
vote
|
|
In this tutorial I will describe how to install and configure MyDNS, a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. This has the advantage that you can easily use web-based frontends to administrate your DNS records. You could even write your own frontend, e.g. using PHP, to interact with the MyDNS database. MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted! This is a major advantage.
I will also show how to set up a secondary DNS server, but I will not use normal zone transfers to get the records from the primary to the secondary DNS server; instead, I will use MySQL database replication. I will simply replicate the data from the primary to the secondary server.
There are multiple web frontends to MyDNS. Of course, you can use phpMyAdmin for the MyDNS administration, or you can use the web frontend that comes with MyDNS (which is not for beginners because it lacks the field descriptions), or you can use MyDNSConfig, a tool written by myself. I will show how to install each of them. read more... |
