• Three Ways To Access Linux Partitions (ext2/ext3) From Windows On Dual-Boot Systems

  Author: Falko Timme • Tags: linux, other • Comments: 49

  Three Ways To Access Linux Partitions (ext2/ext3) From Windows On Dual-Boot Systems If you have a dual-boot Windows/Linux system, you probably know this problem: you can access files from your Windows installation while you are in Linux, but not the other way round. This tutorial shows three ways how you can access your Linux partitions (with ext2 or ext3 filesystem) from within Windows: Explore2fs, DiskInternals Linux Reader, and the Ext2 Installable File System For Windows. While the first two provide read-only access, the Ext2 Installable File System For Windows can be used for read and write operations.

• Splitting Apache Logs With vlogger

  Author: Falko Timme • Tags: apache • Comments: 1

  Splitting Apache Logs With vlogger Vlogger is a little tool with which you can write Apache logs broken down by virtual hosts and days. With vlogger, we need to put just one CustomLog directive into our global Apache configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split Apache's overall access log into access logs for each virtual host each day, and you do not have to configure Apache to write one access log per virtual host (which could make you run out of file descriptors very fast).

• Virtual Users And Domains With Postfix, Courier And MySQL (Mandriva 2008.0)

  Author: Falko Timme • Tags: antivirus, mandriva, postfix • Comments: 1

  Virtual Users And Domains With Postfix, Courier And MySQL (Mandriva 2008.0) This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

• Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch

  Author: Falko Timme • Tags: backup, debian • Comments: 2

  Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

• Set Up Postfix For Relaying Emails Through Another Mailserver

  Author: Falko Timme • Tags: postfix, postfix • Comments: 18

  Set Up Postfix For Relaying Emails Through Another Mailserver This short guide shows how you can set up Postfix to relay emails through another mailserver. This can be useful if you run a Postfix mailserver in your local network and have a dynamic IP address because most dynamic IP addresses are blacklisted today. By relaying your emails through another mailserver that is hosted on a static IP address in a data center (e.g. your ISP's mailserver) you can prevent your emails from being categorized as spam.
