Hoe te om de geautomatiseerde steunen van Linux te creëren/van het Unix

door Sukrit Dhandhania op 18 november, 2008

Linux

Een „steek bespaart op tijd negen“, gaat het oude zeggen. In de wereld van computers die wij naar die steek als steunen hebben verwezen. Wanneer het runnen van een infrastructuur van productieIT, is het noodzakelijk dat wij een uptime op onze servers en toepassingen van zoals dicht bij honderd percenten mogelijk bereiken. Terwijl er een aantal manieren zijn om een de infrastructuurvast lichaam van IT te maken, is het onmogelijk om tot het mislukkingsbewijs te maken. Zo maken wij een plan B.

De servers worden gemaakt van drie brede lagen - de hardware, het werkende systeem en de toepassingen, en de gegevens. In het geval van een hardwaremislukking is het eerder eenvoudig om de machine met nieuwe te vervangen. Installerend het werkende systeem en de toepassingen ook zijn vrij eenvoudig. Het deel dat moeilijk is te vervangen is het gegeven en de configuratie dat uw toepassingen gebruiken. In het geval van mislukking is dit het deel dat niet kan worden vervangen. Zo wij steun dat gegeven periodiek. Wij steunen het zodanig dat het gemakkelijk wordt in geval van nood terug te winnen. [klik om verder te gaan…]

door Sukrit Dhandhania op 17 november, 2008

Linux

Behalve videospelletjes één van de grote voordelen om computers te gebruiken is dat zij niet schijnen letten op doend boring en herhaalde taken geen die wij eerder zouden doen. Voor monotone taken zoals het runnen van dagelijkse steunen zijn wij beter van het plannen van hen om in een bepaalde tijd elke dag te lopen, en interessanter materiaal met onze tijd te doen. Linux en het UNIX komen gewoonlijk met het nut „crontab“ door gebrek. Dit zeer nuttige bevel staat u toe om taken te plannen om in een gespecificeerde tijd te lopen en te herhalen zoals gevormd. Taak het geplande gebruiken wordt „crontab“ genoemd een „cronbaan“. [klik om verder te gaan…]

How to use dstat to monitor your Linux/UNIX server

by Sukrit Dhandhania on November 13, 2008

Linux

If you have a Linux server running at your office or at a data center for which you are responsible, you want to maintain an uptime of as close to a hundred percent. In such a case you want to make sure you keep an eye on how the system is running. To be precise you want to monitor all the system resources that contribute to the system running fine which then results in a high uptime. Memory, CPU, disk usage… are some of the things you want to observe. We would usually use a combination of the tools that come with a Linux or UNIX installation, such as “free”, “top”, “vmstat”… I’ll introduce you to a tool that gives you just about all the info that the other tools combined give you, all under one roof - Dstat. The developer of this command line tool, Dag Wieers, calls it “a versatile replacement for vmstat, iostat, netstat and ifstat”. He adds that “Dstat overcomes some of their limitations and adds some extra features…” To me Dstat is the mother of all command line system monitoring tools. It’s simple to install, easy to use, can be tweaked with ease, and it generates reports that you can plot as a graph to impress your boss. [click to continue...]

How to Remove Shortcut Icons in 64bit Vista

by Skyler Huse on November 11, 2008

Windows

I recently made the switch from 32 bit Vista to 64 bit. Mostly everything went just as smoothly as my old 32 bit OS, but there were a few hiccups. For example, previously mentioned WinSecret no longer had the option for hiding shortcut arrows! This may seem like a small thing, but Vista’s shortcut arrows take up about 3/4th of the actual icon sometimes. [click to continue...]

Using the Firefox Addon - User Agent Switcher

by Ken Murray on November 6, 2008

Firefox

I’m not a Windows user, so I’m not an Internet Explorer user. I have a Hotmail account just so I can chat with friends who only use MSN Messenger. Some of these friends feel the need to send email to my Hotmail account rather than my Gmail account so I do log in to check it now and again. Of course, I’m using Firefox on Linux, so things should work just fine, right? Not entirely. [click to continue...]
