DNS Common Abuses

Post date: April 17, 2005, 09:04 Category: Security Views: 2369 Comments
Tutorial quote: In paper I have present several features of DNS to make the reader familiar with the basics of the Domain Name System. I have also covered several well known and wide spread attacks that are used to exploit DNS. These attacks are by no means theoretical. In truth they grow more and more common as attackers become more sophisticated. The suggested defense methods outlined at the end of each section cover only the basic recommendations that can be used to thwart attackers.

Speedup DNS requests with a local cache

Post date: April 26, 2006, 09:04 Category: Network Views: 2711 Comments
Tutorial quote: One common server bottleneck is DNS lookups. Many common server tasks such as from looking up hostnames to write Apache logfiles and processing incoming mail require the use of DNS queries. If you're running a high-traffic system it might be useful to cache previous lookups.

Creating A DNS Cache With djbdns

Post date: May 5, 2007, 22:05 Category: Installing Views: 3706 Comments
Tutorial quote: Building a local DNS cache will speed up your internet connection since the time for the translation job (converting domain names into IP addresses) will become negligible with the assumption that the DNS cache gets the information from the parent DNS.

How To Install And Use The djbdns Name Server On Debian Etch

Post date: January 24, 2008, 11:01 Category: Installing Views: 2997 Comments
Tutorial quote: djbdns is a very secure suite of DNS tools that consists out of multiple parts: dnscache, a DNS cache that can be used in /etc/resolv.conf instead of your ISP's name servers and that tries to sort out wrong (malicious) DNS answers; axfrdns, a service that runs on the master DNS server and to which the slaves connect for zone transfers; and tinydns, the actual DNS server, a very secure replacement for BIND.

Running A MySQL-Based DNS Server: MyDNS

Post date: January 23, 2006, 15:01 Category: Network Views: 3554 Comments
Tutorial quote: 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.

How to set up a home DNS server

Post date: December 17, 2006, 17:12 Category: Network Views: 10026 Comments
Tutorial quote: In the first part of this series on the Domain Name System (DNS), we set up a caching nameserver that allowed our clients to take advantage of faster network operations by caching frequently requested DNS queries. In this article, we will extend our caching nameserver to a master nameserver that is responsible for managing the authoritative information for our internal client hostnames.

How To Run Your Own DNS Servers With ISPConfig 3 (Debian Squeeze)

Post date: July 21, 2011, 10:07 Category: Miscellaneous Views: 2866 Comments
Tutorial quote: This tutorial shows how you can run your own DNS servers (primary and secondary) with ISPConfig 3. To do this, you need two servers with two different public IP addresses and with ISPConfig 3 installed. I will use Debian Squeeze for both DNS servers here to demonstrate the base system setup process and ISPConfig 3 installation, but once you have ISPConfig 3 installed on your servers, the configuration inside ISPConfig 3 is identical, no matter what distribution you use.
