feh - lightweight but powerful image viewer
2008-02-06 02:49:00 Let's continue with the light weight applications, this time I will show you a great image viewer, that does not need too much disk space nor hardware requirements. The application is feh, to install it run: sudo aptitude install feh then to use it, you will have to be used to command line, but that is one of the great things about Linux isn't it? If you want to open a single picture run: feh /path/to/the/picture/picture.png If you need to open a whole directory with pictures run: feh /directory/ This will open the first picture on that directory, and you can navigate with the left and right arrows, you will notice that if the size exceeds your monitor size, you will not be able to see the whole picture, to avoid this, you can use. feh -g 1024x768 /directory/ This way you will have a window, of 1024x768 pixels, and the picture will be stretched to that size, you can of course use any geometry you prefer. you can can also use it in full screen mode feh -F /directory/ This will ope...

2008-02-05 12:30:00 If you want to keep always the latest available copy of Skype on your computer, not having to check the skype home page every time, you may want to use the skype repository for Debian , which also works for Ubuntu . First add this line to your /etc/apt/sources.list deb http://download.skype.com/linux/repos/deb ian/ stable non-free which can be done with this command: sudo echo "deb http://download.skype.com/linux/repos/deb ian/ stable non-free" >> /etc/apt/sources.list once that is done, install the software with: sudo aptitude update sudo aptitude install skype You will have to accept untrusted packages, as I could not find the key for skype repository. then you are done.

How to start programs with FluxBox at startup
2008-02-04 01:24:00 If you are using FluxBox and want to start programs when you log into FluxBox, you will need to edit the file $home/.fluxbox/startup. As you can see each user will have its own startup script, so each one of them can have their own programs starting at login time. The startup script may look like this: # fluxbox startup-script: # # Lines starting with a '#' are ignored. # You can set your favourite wallpaper here if you don't want # to do it from your style. # # fbsetbg -f /home/ggarron/pictures/wallpaper.png # # This sets a black background /usr/bin/fbsetroot -solid black # This shows the fluxbox-splash-screen # fbsetbg -C /usr/share/fluxbox/splash.jpg # Other examples.

The perfect light Debian with Fluxbox
2008-02-03 20:35:00 As I have mentioned in previous posts, I use to work on Desktops PCs, one in my office and one in my Home, I use my Laptop (an old IBM T30) only when I travel, and as I like to travel light, this also goes for my Laptop, so here I will show how do I configured my Laptop with Debian Lenny, and just the necesary software for my job while abroad.

How to add sub-menus to FluxBox
2008-02-02 16:16:00 I have started using FluxBox, which is an alternative to KDE or Gnome or XFCE, FluxBox is smaller than all the other three mentioned by me, and it is also faster, FluxBox is the Default windows manager for DSL (Damn small Linux). Well after this really small introduction, let's go to the point. To access the menu just right-click on the Desktop and you will see the menu of FluxBox, but if you want to add another application, like VMware you will have to edit the file $HOME/.fluxbox/menu with your favorite text editor, by default it should look like this: [begin] (fluxbox) [include] (/etc/X11/fluxbox/fluxbox-menu) [end] Now if you want to add another menu [begin] (fluxbox) [include] (/etc/X11/fluxbox/fluxbox-menu) [submenu] (Virtual) [exec] (Vmware) {vmware} [end] [end] If you want to add a sub-menu inside the first menu: [begin] (fluxbox) [include] (/etc/X11/fluxbox/fluxbox-menu) [submenu] (Virtual) [exec] (Vmware) {vmware} [submenu] (other-...

Using Lynx to store a page as text to read it later
2008-02-02 15:02:00 Sometimes you may want to store a web page as text to read it later, here is a small tip to achieve that, we are going to use Lynx for that. If you do not have it installed you can use your package manager to install it, taking Debian as example: sudo aptitude install lynx then run: lynx -dump http://www.go2linux.org > $HOME/go2linux.txt You will have the home page of Go2linux stored in your Home as go2linux.txt, and you can read it later as your convenience.

Determining the type of file
2008-01-31 21:26:00 As some of you may know Linux does not use the extension (suffix) of the file to determine the type of it, what it does is to look at the file content. So you can name your files as you want and Linux will still be able to recognize it. If you ever need to know the type of a given file, with no suffix, or with the incorrect suffix, use the Linux command file You should have this command already installed on your Linux, but if not, installing it is really simple. Debian / Ubuntu sudo aptitude install file once installed, you can start guessing the file types. Example: $ ls *.txt -l -rw-r--r-- 1 ggarron ggarron 25511 2007-10-25 17:37 dhclient.txt -rw-r--r-- 1 ggarron ggarron 77757 2007-11-09 10:48 gammu.txt -rw-r--r-- 1 ggarron ggarron 1298 2007-11-20 16:46 latex.txt -rw-r--r-- 1 ggarron ggarron 73823 2007-08-31 11:29 man-iptables.txt -rw-r--r-- 1 ggarron ggarron 142738 2008-01-02 17:28 nmap.txt -rw-r--r-- 1 ggarron ggarron 9834 2007-12-13 18:12 picture.txt -rw-r--r-- 1 ggarro...

Manage your wifi networks and profiles with wifi-radar
2008-01-26 16:31:00 I have been traveling the last two weeks, and I have found how useful is wifi-radar on my Linux powered laptop. I have an IBM Thinkpad T30 with an Aironet Wifi internal card (for the records) As you may see on the wifi-radar home page, there are packages for Gentoo, Debian, Ubuntu and Suse, I have seen that the Gentoo link is broken, but it is also easy to install on it. Installing wifi-radar Gentoo emerge wifi-radar Debian / Ubuntu sudo aptitude install wifi-radar Fedora sudo yum install wifi-radar The first time you run wifi-radar, it will detect the available networks in that place and list it on the screen, like the screenshot below. You should create profiles for all connections you may want to connect, and then select the one you want to connect and click on connect, and if all your configuration is OK you will connect to that network. You can also run it as a daemon to do this run: sudo wifi-radar -d Wifi-radar will try to connect to the default networks you have configured... More About: Networks , Profiles , Radar , Manage
iftop - Check and analyze your traffic
2008-01-22 10:15:00 Introduction iftop is a real good utility both for your own PC/Laptop and for your server and specially good for the latter and even better if this server is acting as the main router in your premises. Well lets explain what iftop does, it is more or less like top, or htop but it does not measure the processes in the processor, but it measure the "processes" in the ethernet interface, giving you information about the IPs that have a connection with the PC where iftop is running, also giving information about the traffic, if it is incoming or outcoming, also how much traffic there is in that connection and the total amount of traffic in the interface. Installation Ubuntu / Debian sudo aptitude install iftop Fedora / CentOS yum install iftop Gentoo / Sabayon emerge iftop Some options Some of the options I use the most are: -p Enables promiscuous mode, so the traffic on any interface (if there is more than once) is checked and counted -P Shows also the port that connection is using bo...

Trolltech releasing QT under GPL3
2008-01-19 12:42:00 Yesterday at the KDE developer conferences, Trolltech CEO Haavard Nord announced that the QT cross-platform developer toolkit is going to be released under GPL 3, this are really good news for KDE developers, and also for any developer who uses QT toolkit. So maybe we will soon will be able to see the "buy" button for QT disappear, and it will be easier for developers to release its job. I am not a lawyer but as far as I understand, this also means that nobody will be able to use QT to sell "closed code" applications, and all applications developed using QT will have to be under GPL 3, maybe I am wrong. But I do still think this are good news. via: arstechnica If you read the comments under the original article, it seems to be an addition to the other licenses options they already have, and it seems that If you want to have your software closed, you will still have the option to pay for QT and keep your application code for you. Maybe we need a lawyer's analysis here.

CPU load
2008-01-15 06:18:00 One important thing to check on your Linux box, is the CPU utilization, specially if usually compile software, or if you have server applications running on your PC. One good tool to check this is: htop, which will show you a lot of useful information, the important data is the load average, that will show you if you are having processes waiting for the CPU or not. the three numbers shows your the load average in the last 1 minute, 5 minutes and 15 minutes, so you will also see the trend of the CPU usage, and now how much is good and how much is overloaded? Well it depends on how many CPUs your system have, one good explanation I have found about at: Linux Journal says: The point of perfect utilization, meaning that the CPUs are always busy and, yet, no process ever waits for one, is the average matching the number of CPUs. If there are four CPUs on a machine and the reported one-minute load average is 4.00, the machine has been utilizing its processors perfectly for the last 60 sec... More About: Load

From the man page: Nmap (“Network Mapper”) is an open source tool for network exploration and security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. While Nmap is commonly used for security audits, many systems and network administrators find it useful for routine tasks such as networ... More About: Networks , Open , Scan , Ports , Hosts
