How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10
Author: Falko Timme •
Tags: mysql, security, ubuntu •
Comments: 3 How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10 This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

How To Add Two-Factor Authentication To Openvpn AS With The WiKID Strong Authentication Server
Author: nowen • Tags: security • Comments: 0How To Add Two-Factor Authentication To Openvpn AS With The WiKID Strong Authentication Server It's been a while since our last tutorial on how to add two-factor authentication to OpenVPN using the WiKID Strong Authentication System. The people at OpenVPN have been very active lately and it seems like a good time to take a look at what they've done. It's still dead simple to configure, but it is mostly done via the new slick web interface.

Comments: 0 Trafficanalysis Using Debian Lenny By using my Network Monitoring Appliance we noticed a link in MRTG always under heavy load. On this link a lot of different traffic aggregates, so we decided to analyze of what quantities of protocols and therefore applications the cumulative traffic consists.

Setting Up A PXE Install Server On Ubuntu 9.10

Comments: 11 Setting Up A PXE Install Server On Ubuntu 9.10 This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 9.10 (Karmic Koala). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs.

Comments: 0 How To Back Up MySQL Databases With mylvmbackup On Debian Lenny mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on a Debian Lenny server.

How To Set Up A USB-Over-IP Server And Client With OpenSUSE 11.2

Tags: suse •
Comments: 2 How To Set Up A USB-Over-IP Server And Client With OpenSUSE 11.2 This tutorial shows how to set up a USB-over-IP server with OpenSUSE 11.2 as well as a USB-over-IP client (also running OpenSUSE 11.2). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 9.10 (Karmic Koala)
Author: Falko Timme •
Tags: ftp, ubuntu •
Comments: 0 This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.
