Such lists are currently used by mail servers for filtering incoming emails and blocking the ones listed, in order to improve mail security and integrity. The blacklist is also the opposite of what is called a whitelist. falko Fri, 06 Jul 2007 15:00:49 GMT http://www.howtoforge.com/how-to-back-up-an-ubuntu-8.10-system-with-systemimager SystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image). This means that you have to install some software on your image server and on your golden client in order to run SystemImager. This tutorial shows how to install a SystemImager server and a SystemImager client, both using Ubuntu 8.10, and how to create/update/restore/delete images. falko Thu, 13 Nov 2008 12:57:18 GMT http://www.howtoforge.com/how-to-back-up-mysql-databases-with-mylvmbackup-on-ubuntu-12.10 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 an Ubuntu 12.10 server. falko Tue, 15 Jan 2013 11:19:30 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
