In this article I will explain how to install it as a Postfix filter on Debian Etch. falko Tue, 08 Jan 2008 11:50:47 GMT http://www.howtoforge.com/back_up_mysql_dbs_without_interruptions This article describes how you can back up MySQL databases without interrupting the MySQL service. Normally, when you want to create a MySQL backup, you either have to stop MySQL or issue a read lock on your MySQL tables in order to get a correct backup; if you do not do it this way, you can end up with an inconsistent backup. To get consistent backups without interrupting MySQL, I use a little trick: I replicate my MySQL database to a second MySQL server, and on the second MySQL server I use a cron job that creates regular backups of the replicated database. falko Mon, 14 May 2007 09:54:57 GMT http://www.howtoforge.com/how-to-benchmark-your-system-cpu-file-io-mysql-with-sysbench sysbench is a benchmark suite which allows you to quickly get an impression about system performance which is important if you plan to run a database under intensive load. This article explains how to benchmark your CPU, file IO, and MySQL performance with sysbench. falko Sun, 22 Jul 2012 10:20:14 GMT http://www.howtoforge.com/block_spam_at_mta_level_postfix The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails. falko Wed, 06 Jun 2007 09:59:29 GMT http://www.howtoforge.com/kernel_compilation_debian_etch Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on a Debian Etch system. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there. falko Thu, 14 Jun 2007 12:19:51 GMT http://www.howtoforge.com/compile_rtorrent_from_svn_ubuntu Torrent is a great way to transfer large files very quickly. However most torrent clients are gui based and have quite some impact on system resources (e.g. Azureus). rTorrent is a lightweight client running from the terminal. Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location. falko Wed, 19 Sep 2007 08:34:34 GMT http://www.howtoforge.com/sane_xsane_scanner This article shows how you can make your scanner (SCSI or USB) work with SANE/XSANE from a normal user account without getting permission errors. falko Sat, 07 Apr 2007 01:33:41 GMT http://www.howtoforge.com/convert_songs_to_mp3_ogg_with_k3b This guide describes how you can use the CD/DVD burning application K3b to convert songs from an audio CD into MP3 or Ogg files that you can use on your MP3 player, for example (if you choose the Ogg format, your MP3 player must support it). falko Thu, 09 Aug 2007 10:17:59 GMT http://www.howtoforge.com/enable-multiple-https-sites-on-one-ip-using-tls-extensions-on-debian-etch This guide is Debian specific but could be ported to other distributions since the concept is the same. In order to use TLS Extensions we have to patch and recompile Apache2 and recompile OpenSSL with the enable-tlsext directive. Since TLS extensions are relatively new, some Internet browsers will not work so the Apache2 server will deliver just the default site as http 1.0 does on an http 1.1 server. falko Mon, 19 Nov 2007 11:17:12 GMT http://www.howtoforge.com/ntfs_3g_mandriva2007_spring Normally Linux systems can only read from Windows NTFS partitions, but not write to them which can be very annoying if you have to work with Linux and Windows systems. This is where ntfs-3g comes into play. ntfs-3g is an open source, freely available NTFS driver for Linux with read and write support. This tutorial shows how to install and use ntfs-3g on a Mandriva 2007 Spring desktop to read from and write to Windows NTFS drives and partitions. falko Wed, 05 Sep 2007 09:18:19 GMT
