The following tutorial covers the process of remotely accessing and controlling a Ubuntu installation from another PC that is using Windows or Ubuntu. This process should also work for USB Pendrive linux and other Debian based operating systems (with minimal changes) running either from a local hard disk, CD or portable USB device as long as the system is connected to a network and or has an internet connection established and has Remote Desktop (vino vncviewer) installed.
The psmisc package is probably installed on almost all Debian and Ubuntu installations and contains a number of small tools related to process management on Unix systems. Namely, these are
peekfd. Below follows a short description of these useful tools.
Most linux users know about the root directory, but many of the folders contained in / are a mystery as to their purpose. I wanted to write about this in one of my switching to linux articles, but it would have made the article far to long, so I’ve made a separate post about it. I hope this article will better prepare you better for managing your linux system, no matter what you use it for. With no more ado, here we go!
Since dumping Windows I have learned a lot about Linux. Ubuntu to be specific. You should really try it if you are still using Windows. There must be 100’s of apps I might be missing here which is great. i just wanted to point out these that I really like and did not have in windows as standard or as updates. Except the updates of course which in Windows make you shut down your pc while they waste your time.
The Ubuntu Media Centre Team have decided to use Elisa as their core infrastructure to push the free software media centre effort forward. Elisa is a open source cross-platform media centre, designed to be as simple to use as possible.
This howto outlines the process by which one can set up the Subversion version control system, and have it work in tandem with Trac, the project manager for software development projects, on a server running Ubuntu (or possibly Debian). It is brought to you by Openject Consulting.
I love Ubuntu as it is simply the best operating system that I have come across. If there is one thing that I dislike about Ubuntu, it has to be the desktop. Don’t get me wrong, it is not GNOME that I dislike, but the default color and theme that Ubuntu use for their distribution. I just can’t stand the brown color and theme.
A full system crash (hang) is very rare on Linux. Here’s the bad news: It is still possible for programs on Linux to misbehave themselves (they are not spoiled, probably just coming down with something, or maybe growing). Perhaps the application went into an endless loop because it was feeling lonely, or just stopped responding because it was pouting when I accidentally mentioned something Microsoft-related.
I have just discovered that ext3 defaults to reserving 5% of its partition exclusively for root, as a precaution measure that your system does not get FUBAR when you use it for your root partition. I have a 230GB external USB disk that I use for all my big storage requirements, downloaded stuff, backups etc. Due to this reservation I had 11.5GB of unusable disk space, thankfully this is easy to fix:
Wine allows users to run Windows programs natively under Linux without paying a dime. However, there's a tiny problem: programs running in Wine don't look so great. They don't even try to fit into your native GNOME or KDE color scheme or use your preferred fonts. You could use a Windows theme, but themes make Wine run extremely slowly. Luckily, with a little configuration editing, it's easy to make Wine applications look at lot more like the rest of the apps on your desktop.
When you spend a lot of time in front of your computer, many small actions performed repeatedly can add up to a lot of wasted time. The worst of these small offenders is the copy and paste… so how can we simplify this in Firefox?
WiFi Radar is a Python/PyGTK2 utility for managing WiFi profiles.It enables you to scan for available networks and create profiles for your preferred networks. At boot time, running WiFi Radar will automatically scan for an available preferred network and connect to it. You can drag and drop your preferred networks to arrange the profile priority.
KDE 4.0.0 was released on Friday. For the KDE team, it represents a huge leap forward in many areas, one of them being that they didn't add a K onto the name of every new app. For once. But elsewhere, KDE 4 brings huge enhancements both on and under the surface.
This document is a step by step guide for configuring Ubuntu 7.10 as a Samba Domain Controller with an LDAP backend (OpenLDAP). The point is to configure a server that can be comparable, from a central authentication point of view, to a Windows Server 2003 Domain Controller. The end result will be a server with an LDAP directory for storing user, group, and computer accounts. A Windows XP Professional SP2 workstation will be able to join the domain once properly configured.
I spent some time this evening with the KDE 4.0 LiveCD to see what all the hoopla was about. I have been excited to see all the new improvements in the long anticipated KDE 4.0, as I’m sure many of you have been. Below are some of my inital impressions after half-hour with the LiveCD.
GNU/Linux is bursting with information about the system on which it runs. The system's hardware and memory, its Internet link and current processes, the latest activity of each user -- all this information and more is available. And, despite such desktop tools as the KDE Control Center or GNOME's System Monitor, the easiest place to get all the system information available is still the command line.
Avant Window Navigator (Awn) is a dock-like bar which sits at the bottom of the screen. It has support for launchers, task lists, and third party applets.The Awn project is the development of the ‘dock’, avant-window-navigator, and its corresponding shared library ‘libawn’, which is used to develop applets.
nmap is a wonderful tool specially for debugging, there are lots of times when you need to know if a port is open in a server, or maybe blocked by a firewall, or just to test your iptables rules. Here we will learn how to use it at the command line, and using its GUI front end, nmapFE and Knmap.
I only had a little time today to play with Ubuntu 8.04 Alpha 3, so here are a few of the new features and some thoughts:
The wealth of applications on a modern Linux system is phenomenal, but sifting through screen after screen of menu items is no fun. Likewise, it's convenient to have all of your files in one place, but the more you have the longer you have to look for the one you need.
gnome-volume-manager is the Gnome daemon in charge of controlling how removable media is going to be treated in Linux (When using Gnome).
RIG (Random Identity Generator) is a free replacement for a shareware program out there called ‘fake’. It generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself.
KDE 4.0 is the innovative Free Software desktop containing lots of applications for every day use as well as for specific purposes. Plasma is a new desktop shell developed for KDE 4, providing an intuitive interface to interact with the desktop and applications. The Konqueror web browser integrates the web with the desktop. The Dolphin file manager, the Okular document reader and the System Settings control center complete the basic desktop set.
Many Linux distributions try to be visually appealing. Some use Beryl-Compiz for cool 3-D effects on resource-laden boxes, while others turn to desktops like Enligtenment for a little bit of gloss at the expense of functionality. Geubuntu is a new distro that combines the best of those two worlds, equipping Enlightenment with bits from GNOME and Xfce on top of Ubuntu.
