    · posted by ryuzaki0 · from the not-welcome-here dept. · 158 comments
    hausmasta writes, "In this guide you will learn how to tweak your virtual Postfix setup to better combat spam by stopping the mail before it hits SpamAssasin, using RBL (Realtime Blacklists) and RHBL (slightly different), greylistings, and Helo Checks." A clear, step-by-step guide to a complex subject.

  2. LDAP Authentication in Linux

    · posted by ryuzaki0 · from the roadmaps dept. · 189 comments
    hausmasta writes "HowtoForge has published a walkthrough to show you how to store your users in LDAP and authenticate some of the services against it. It will not show how to install particular packages, as it is distribution/system dependent, instead it will focus on pure configuration of all components needed to have LDAP authentication/storage of users. The howto assumes that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch."

  3. Automate Spamcop Submissions

    · posted by ryuzaki0 · from the spam-is-bad-mmkay dept. · 183 comments
    hausmasta writes "Spamcop is pretty much dependent on user input. If no one submits and verifies spam, then they will have no blacklist. However that whole submission and verification process is a bit annoying. Why should I bother to actually submit spam to Spamcop and have it verified? If I just delete it, that will take less time.. This tutorial shows how to automate the Spam Cop submission and verification process. All I do is just put the spam into certain folders and our good old friend cron does the rest."

  4. Server Monitoring With Munin And Monit

    · posted by ryuzaki0 · 124 comments
    hausmasta writes "In this article I will describe how to monitor your server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services."

  5. Building A Web-And Mail Server With CentOS 4.3

    · posted by ryuzaki0 · from the learn-more-about-it dept. · 26 comments
    hausmasta writes "This is a detailed description how to set up a CentOS 4.3 based server that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.). This tutorial is written for the 64-bit version of CentOS 4.3, but should apply to the 32-bit version with very little modifications as well."

  6. How To Set Up A Load-Balanced MySQL Cluster

    · posted by ryuzaki0 · from the someone-teach-me-please dept. · 127 comments
    hausmasta writes "This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster)."
