Turning gnome-terminal to a Pop-up Terminal
Tuesday, February 03, 2015 @ 10:25:09 UTC by lbadmin (942 reads)
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.

How to configure SNMPv3 on ubuntu 14.04 server
Monday, September 29, 2014 @ 11:29:35 UTC by lbadmin (2763 reads)
Ubuntu Linuxgg234 writes
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

RationalPlan Single becomes free on Linux:

Starting with version 4.7 RationalPlan Single is distributed as freeware under all Linux operating systems. RationalPlan is a project management suite that puts the accent on productivity, ease of use and fast learning. The Single version can be seen as an alternative to Microsoft Project and the perfect solution for novice or accidental project managers.

RationalPlan products work on all major operating systems including Windows, Linux and Mac OS X. This is a major advantage as it offers cross platform compatibility. Linux platform was the last one that was adopted and presents the best integration with Ubuntu distributions (the products are even listed under the Ubuntu Apps Directory). Even more the company decided to offer the Single version as freeware on Linux. This decision is aiming to help the educational environment (students, teachers) and non-profit organizations.

How To Setup Your own Mail Server With Anti-Spam Configuration in 60 Minutes
Wednesday, September 10, 2014 @ 12:07:53 UTC by lbadmin (3052 reads)
Ubuntu Linuxmikeskril writes

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

How to manage a WiFi connection from the command line
Monday, September 01, 2014 @ 12:21:25 UTC by lbadmin (3347 reads)
Networkingxmodulo writes
Whenever you install a new Linux distribution on a computer, it is in general recommended that you connect to the internet via a wired connection. There are two main reasons for this: one, your wireless adapter may not have the right driver loaded; second, if you are installing from the command line, managing WiFi is scary. I always tried to avoid dealing with WiFi over the command line. But in the Linux world, there is no place for fear. If you do not know how to do something, that is the only reason you need to go ahead and learn it. Full Story

Configure NFS Server and Client Configuration on Ubuntu 14.04
Friday, August 08, 2014 @ 11:20:31 UTC by lbadmin (3777 reads)
Ubuntu Linuxgg234 writes
NFS was developed at a time when we weren't able to share our drives like we are able to today -- in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment. While this seems like a standard service to offer, it was not always like this. In the past, clients and servers were unable to share their disk space. Thin clients have no hard drives and thus need a "virtual" hard-disk. The NFS mount their hard disk from the server and, while the user thinks they are saving their documents to their local (thin client) disk, they are in fact saving them to the server. In a thin client environment, the root, usr and home partitions are all offered to the client from the server via NFS. Full Story
