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

Post date: January 24, 2008, 11:01 Category: Installing Views: 3023 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.

Using the GNU Privacy Guard

Post date: April 16, 2005, 00:04 Category: Software Views: 2426 Comments
Tutorial quote: Tonight we will investigate the gnupg utility (version 1.07). I will be running it on an OpenBSD 3.2 system but, as usual, any unix-like system should not display any significant differences. I will assume that GPG is already installed.

The GNU Privacy Guard can be regarded as a complete replacement for the popular PGP (Pretty Good Privacy) software. The difference between the two is that GnuPG does not have any licensing restrictions and it also runs on more platforms. They are both open source products. Although owned by a commercial entity, a freeware version of PGP is available (although only for Windows and Macintosh).

In a nutshell, what all this software does is allow two parties to communicate securely. This implies the following:
- the message has arrived at its destination unaltered
- the message can only be read by its intended recipient
- the authenticity of the sender has been verified by the recipient

Creating DjVu Documents Linux HOWTO

Post date: July 16, 2006, 16:07 Category: Miscellaneous Views: 3680 Comments
Tutorial quote: This document explains some of the uses of djvulibre implementation of DjVu for creating quality DjVu documents in linux. DjVu format features bitmap document compression and hypertext structure. It is used by numerous web sites all around the world for storing and distributing digital documents including scanned documents and high-resolution pictures. One of the advantages of DjVu files is that they are notably small, often smaller than PDF or JPEG files with the same content. This makes DjVu a helpful tool for digitizing books and journals, especially scientific ones.

Below it is considered the case when a DjVu document is created from a number of separate JPEG files each containing a single page. Here JPEG format is not a limitation, and the examples can cover arbitrary image formats. Conversion from PDF to DjVu is also discussed. Usage of scanner software is not explained: refer to the relevant documentation.

Change your Network card MAC ( Media Access Control) address

Post date: December 4, 2007, 10:12 Category: Network Views: 3049 Comments
Tutorial quote: Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

If you want to change your network card mac address you need to use simple utility called mac changer.MAC changer is a utility for manipulating the MAC address of network interfaces

ACL(Access Control List) Configuration

Post date: April 4, 2006, 20:04 Category: Installing Views: 3101 Comments
Tutorial quote: Access Control Lists (ACLs) provide a much more flexible way of specifying permissions on a file or other object than the standard Unix user/group/owner system. Windows NT and above, when running on an NTFS partition, use ACLs to specify permissions on files and directories. This document attempts to show how you can enable ACL support on your Linux box and use Samba to provide an SMB file server for use by machines in a Windows 2000 domain.

ACLs are best stored in the actual file system itself. To that end, there are patches available for ext2 and ext3 that enable ACL support using Extended Attributes (EAs). SGI's XFS also has ACL support built in, but XFS is not currently covered in this document.
