Tutorial quote: The current leading SSH server, OpenSSH, offers two main methods of authentication: interactive password and public key authentication. While interactive password authentication is the default, there are several reasons for using public key authentication. After reading some background information about public key cryptography, you should have a firm understanding of what public key cryptography is and how it works. You're welcome to skip straight to generating keys for use with SSH. Setting up public key authentication will require a few minutes, but the results are worthwhile.

Master-Master Replication With MySQL 5 On Fedora 8

Post date: February 19, 2008, 11:02 Category: Network Views: 3260 Comments
Tutorial quote: This document describes how to set up master-master replication with MySQL 5 on Fedora 8. Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.
