Controlling Filesystem Mounting on Linux by Playing with /etc/fstab: Controlling the mounting of filesystems is a useful technique for managing Linux systems. The mounting configurations are mostly in the /etc/fstab file. In this post, we will discuss 2 common and useful techniques for controlling the filesystem mounting by playing with the /etc/fstab file: allowing non-root users to mount/unmount filesystems and avoiding mounting failures blocking the booting of Linux.

What Is the Name of the Linux-based OS: A Survey ? Fclose.com: You may already well know ?Linux? and may also use the ?operating system based on the Linux kernel? directly or indirectly (you are indirectly using it now as Fclose.com is hosted on Linux). But how should we name the OS based on Linux? You may know there is GNU/Linux naming controversy. Different people have different opinions about this. Today, let?s see how do these widely used distributions call themselves by looking at their ?about? web pages. Continue reading: What Is the Name of the Linux-based OS: A Survey ?

A PHP Function for Fetching RSS Feed and Outputing Feed Items as HTML ? Fc

A PHP Function for Fetching RSS Feed and Outputing Feed Items as HTML ? Fclose.com: I aggregated all my new posts from several sites into a single RSS feed. Last time I updated my homepage, I came across an idea why not showing these feed items directly on the homepage as HTML content. After some study, I got one single PHP function in my hand that fetches an RSS feed and outputs HTML content in the page.

Turning gnome-terminal to a Pop-up Terminal

HOWTOs and similar articlesericzma writes
Turning gnome-terminal to a Pop-up Terminal: A pop-up terminal is great and handy on Linux and similar OS. On KDE, Yakuake is great. On Gnome or GTK, I ever tried Guake. It is quite good. However, it has not been as mature, stable and figure-rich as gnome-terminal. One day, I got this idea: why not using a script/program to manage the gnome-terminal and take action upon hotkey hits? The top-down effect is non-important to me. What I want is simple: use a hotkey (like F12) to activate/deactivate the terminal.

Lazy Linux Admins Going to Server Rooms Less: Forced Reboot, Auto Reboot after K

Lazy Linux Admins Going to Server Rooms Less: Forced Reboot, Auto Reboot after Kernel Panic and Email Notification after Reboot: Having to go the the server room to reset servers is the most headache thing for admins managing a cluster of Linux servers in a remote site. Either you can ping the server but can not ssh to it, or you even can not ping it. There are various reasons that may cause a Linux server crash or fail to be connected to by SSH. The most common two from my experience are: there may be a bad behaving progress that use up almost all physical memory and swap or there may be a kernel panic. In this post, I describe several techniques I learned to make myself go to the server room less by dealing with these kinds of failures.

Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more.It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. Full Story

Introduction

This tutorial will teach you how to set up your own robust email server. We are focusing on a small personal server with up to a few email accounts. After following this guide, you will have a fully functional mail server and you can connect with your favourite client to access, read and send emails. The Anti-Spam configuration will drop unwanted messages.

Software and technologies used

  • Postfix v2.9.6 as SMTP server
  • Dovecot v2.0.19 as IMAP server
  • We will use Unix user accounts and tunnel the SASL authentication through TLS
  • Postgrey v1.34 ? to reject spam from the beginning
  • SPF (Sender Policy Framework) validating to reduce spam
  • SPF DNS entry to prevent spoofing
  • DKIM (Domain Keys Identified Mail) to sign our email messages
