Server Monitoring With munin And monit On Mandriva 2008.0

Post date: February 26, 2008, 11:02 Category: Installing Views: 3866 Comments
Tutorial quote: In this article I will describe how you can monitor your Mandriva 2008.0 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: graphic that lets you recognize current or upcoming problems, and a watchdog that ensures the availability of the monitored services.

The Perfect Server - Mandriva 2010.1 (Spring) Free (x86_64) [ISPConfig 2]

Post date: July 18, 2010, 17:07 Category: Installing Views: 5556 Comments
Tutorial quote: This tutorial shows how to set up a Mandriva 2010.1 (Spring) Free (x86_64) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box). This tutorial is written for the 64-bit version of Mandriva 2010.1.

Server Monitoring With munin And monit On Debian Etch

Post date: May 13, 2007, 21:05 Category: System Views: 4503 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Etch 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 let 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.

The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]

Post date: October 21, 2010, 11:10 Category: Installing Views: 3937 Comments
Tutorial quote: This tutorial shows how to prepare a Debian Lenny (Debian 5.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This tutorials differs from "The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3]" in that I use BIND and Dovecot here instead of MyDNS and Courier (of course, the other two variants - BIND & Courier or MyDNS & Dovecot are possible as well).

Arcane Linux Commands: dc

Post date: December 31, 2007, 01:12 Category: Miscellaneous Views: 4202 Comments
Tutorial quote: If anybody within earshot of you is struggling to learn sed and ever remarks "This is like learning Klingon! Could they make it any more cryptic?", you can always point them to dc.

dc is the command-line Unix "Reverse-Polish Notation"(RPN) calculator. The name stands for "desktop calculator". OK, so what is a Polish calculator and why would you want to reverse one? The math that you do in school uses infix notation, with the operator between the numbers (3 + 5). Prefix notation puts the operator first (+ 3 5) and is what the Lisp language uses. The prefix notation is known as "Polish notation" after the nationality of Jan Łukasiewicz who invented it. Postfix notation, then, has the operator at the rear (3 5 +), and so is also the reverse of Polish notation.

What's the difference? In computer programming, you have to specify what order you want a multi-part calculation to be in. Everybody is familiar with the old problem of A*B-C. For A=5, B=3, C=2, multiplying first and subtracting second gives you 13, while subtracting first and multiplying second gives you 5. To specify which operations you want performed first, you have to either memorize the complex orders of operations (which change from one language to the next) or use a lot of parenthesis ((A*B)-C) or (A*(B-C)). Hey, that's what everybody complains about in all those languages that use parenthesis!
