internal table. Youcan add as many MAC addresses as you like to the table by issuingmore addmac commands. You then need to tell Host AP what to do withthe table you've built. The maccmd 1 command tells Host AP to use thetable as an "allowed" list, and to deny all other MACaddresses from associating. Finally, the maccmd 4 command boots offall associated clients, forcing them to reassociate. This happensautomatically for clients listed in the table, but everyone elseattempting to associate will be denied. Sometimes, you only need to ban a troublemaker or two, rather thanset an explicit policy of permitted devices. If you need to ban acouple of specific MAC address but allow all others, try this: iwpriv wlan0 addmac 00:30:65:fa:ca:deiwpriv wlan0 maccmd 2iwpriv wlan0 kickmac 00:30:65:fa:ca:deAs before, you can use addmac as many times as you like. The maccmd 2command sets the policy to "deny," and kickmac boots thespecified MAC immediately, if it happens to be associated. This isprobably nicer than booting everybody and making them reassociatejust to ban one troublemaker. Incidentally, if you'd like to removeMAC filtering altogether, try maccmd 0. If you make a mistake typing in a MAC address, you can use thedelmac command just as you would addmac, and it (predictably) deletesthe given MAC address from the table. Should you ever need to flushthe current MAC table entirely but keep the current policy, use thiscommand: iwpriv wlan0 maccmd 3Finally, you can view the running MAC table by using /proc: cat /proc/net/hostap/wlan0/ap_control The iwpriv program manipulates the running Host AP driver, butdoesn't preserve settings across reboots. Once you are happy with thecontents of your MAC filtering table, be sure to put the relevantcommands in an rc script to run at boot time. Note that even unassociated clients can still listen to networktraffic, so MAC filtering actually does very little to preventeavesdropping. To combat passive listening techniques, you will needto encrypt your data.Checkprocesses not run by youDifficulty: Expert Application: bash Imagine the scene - you read our list of Linux Format Awardsnominees this month, saw Crack Attack! on there, and took it uponyourself to give it a (very) thorough testing before casting yourvote in its favour. Sadly, to your shock, the game drags to a haltjust as you're about to beat your uppity subordinate - what could behappening to make your machine so slow? It must be some of thoseother users, stealing your precious CPU time with their scientificexperiments, webservers or other weird, geeky things! OK, let's list all the processes on the box not being run by you! ps aux | grep -v `whoami`Or, to be a little more clever, why not just list the top tentime-wasters: ps aux --sort=-%cpu | grep -m 11 -v `whoami` It is probably best to run this as root, as this will filter out mostof the vital background processes. Now that you have the information,you could just kill their processes, but much more dastardly is torun xeyes on their desktop. Repeatedly! Courtesy: linuxformat Fonte: 58 Cool Linux Hacks!

Lots of people have chosen to make the move from Windows to Linux but do they have 'it' in them to know and understand what's in store? Saturday, January 25, 2014: Well, frankly speaking nobody is perfect, and in the current discussion not everyone is a tech-savy geek. But does that mean they don't have right to feel and enjoy the 'best' things in life (in this discussion, the same pertains to technology). Over the years, many people have switched from Windows to Linux primarily owing to freedom that the latter provides. But, the question remains- is the 'average joe' in you truly familiar with what Linux really is? This goes out to all the people who have heard the term Linux and want to know a bit more but have no clue where to begin. Here are 10 things users must know about Linux:What is Linux?"Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released 5 October 1991 by Linus Torvalds." is how Wikipedia puts it. Most of you will probably have the Windows operating system that has seen a number of versions over the years. Now Windows is an Operating System, while Windows Kernel or the Windows NT Kernel is basically the engine for it. From the Windows NT Kernel multiple versions of Windows are formed including the home, professional and ultimate editions. Now coming to our point: there is a common misconception that Linux is an Operating System (or as even Wiki calls it). Linux is however the engine that spawns a whole host of different operating systems known as distributions.What is a distribution (distro)? The distribution is in fact the actual operating system. So you could look at it like this. There are multiple distributions each aimed at a different target audience. The difference between Linux and Windows is that there are hundreds of choices of Linux distributions with majority of them being free.How do I know which distribution is right for me? This basically comes down to personal preference. A lot of distributions provide live CDs which makes it possible to insert the CD into you CD drive and restart your computer and it will boot straight into the Linux distribution. Simply try out all the functions without worrying about messing up your Windows installation and if you like it you can then install it. However, blindly downloading distributions is not advisable for newbies. You can always visit www.distrowatch.org that convineantly lists the top 100 distributions. Further, the search tool can be used to search on the distribution type. Searching on 'older computers' provides a list of distributions that run well on older computers. Then there are distros for gamers, education and so on. Each distribution has a description which states the major goals of the projects. You can also see screenshots and read reviews.For first timers however, Ubuntu, Linux Mint or Zorin OS might be useful!What is a desktop environment? A
desktop environment is simply a series of menus, taskbars, windows and keyboard shortcuts that you use to start and run applications. Linux offers an abundant choice of desktop environments. The main desktop environments in use are Unity, Cinnamon, Mate, Gnome, KDE, XFCE and LXDE. Where can I get Linux distributions? Most distributions of course come free, however, some distros make it more complicated than others when choosing what to download. Ubuntu is fairly easier since there is only one desktop choice (Unity) and so you simply get the choice to download a 32 bit version or a 64 bit version. How do I install Linux but keep Windows? Some Linux distributions can run from inside Windows or as well as Windows without affecting the Windows install at all for those of you still wanting to hold on to Windows while trying out Linux. For instance, Ubuntu has the Wubi installer which runs Ubuntu from inside Windows. While, many other distros enable you to install the Linux distribution alongside Windows so that when you boot your PC you can choose whether to use Windows or Linux.Can I still run my Windows applications? WINE enables you to install Windows applications within the Linux operating system and run them straight from within Linux. While, VirtualBox enables you to install a copy of Windows within a virtual machine whereby you can install the Windows applications you wish to use.Is my hardware supported by Linux? The answer is a yes! The best thing however is to try out the live version of a distribution first and test all your hardware. How do I get support for Linux? The major distros have forums that you can go to for help. If the forums dont work then there are the ICQ chat rooms. Then there is of course Google and Youtube.Why would I want to use Linux instead of Windows? If your machine is running slowly or it is getting older then you might not be able to upgrade to a later version of Windows. However, the current version of Windows will eventually lose support and there is every chance security holes will be found and not plugged. Moving to a version of Linux that is designed for older computers will give you peace of mind that you are running on an operating system designed for you.

Speed up your Linux machine with these awesome hacks!Monday, October 07, 2013: Although Linux, the brainchild of Linus Torvalds is an extremely reliable operating system, and rarely needs to be rebooted, but when it does, the speed is a major concern. With Matrix style lines scrolling down the screen, it can make many lose patience. But fortunately, there are ways to speed things up. A majority of these tips are not very tricky all though some of these are unfortunately. Lets take a look at top 10 speed hacks of Linux and let your Linux box reincarnate with speed. 1. Quick Fixes - Disable unnecessary services to make Linux boot fasterLinux comes in various flavors bundled with a lot of applications. However, most of us don't even use Linux to its full potential. Depending upon the use of the machine, plenty of services and running programs wont be needed. And if you are using Linux just for a desktop, then you wont be needing the default send mail, httpd, and many other services. You can also turn off many other services if your Linux box is used as a small web server by going to Administration menu, tweaking the Services entry and deselect all of the services you dont want to start. 2. Free up Your Kernel - Disable unnecessary kernel modulesIf your Linux box is wired to the LAN/Ethernet, then you dont need to have a wireless kernel module loaded. More services like smartcard modules and others can be disabled and the load can be taken off from the kernel. This task is a bit difficult as it requires recompilation of kernel, which is daunting for even the Linux geeks. To do this, you will need the kernel sources and then follow the standard steps for compiling a kernel. You will be having a ride through the internals of your system just disable all of the kernel modules you dont need. For added safety, install Bootchart which will tell you if Kernel modules are properly installed and running on your system. Not only will this give you a good list of modules, it will illustrate for you what is happening during your system boot. You can also issue the commandchkconfig list | grep 3:onto find out what services are running. Once you know what loading modules you dont need, you can remove them during a kernel recompilation. While youre at it, compile the kernel to exactly match your architecture.3. Take Load Off Linux - Use a lightweight window manager instead of GNOME or KDEUsing a smaller window manager drastically reduces graphical boot time. Instead of having to wait that extra 30 to 60 seconds for GNOME or KDE to boot up, why not wait two to 10 seconds for Enlightenment or XFCE to boot up? Not only will they save you boot time, they will save your memory and the headache of dealing with bloatware. 4. CUI ROKZ - Use a text-based login instead of a graphical loginThe graphical logins do two things: increase load times and create headaches trying to
recover from an X windows failure. Most of Linux machines which boot to run level 3 instead of run level 5 will halt at the text-based login, where you only have to log in and issue startx to start your desktop of choice. So CUI login is the way to go. 5. The Flying Penguin - Use a lighter Linux distributionAre You a Linux newbie? Instead of loading the heavyweight SUSE, why not try a DSL, Puppy Linux, or Gentoo? The boot time is less than the more bloated Fedora (SUSE and even Ubuntu). Loading lighter Linux distributions will save you from lot of headaches. Of the larger distributions, OpenSuSE claims to boot the fastest, but between the latest Fedora and Ubuntu, Ubuntu blows Fedoras boot times away. 6. Get Savvy - Use an OpenBIOSIf youre tech savvy enough to upgrade your PCs firmware, you might consider migration to open source BIOS which will allow Linux to actually initialize the hardware as it boots (instead of relying on the BIOS). Also, many open BIOSes can be customised to meet your machines specific needs. If you dont go the open BIOS route, you can at least configure your BIOS to not search for a floppy drive thats not there or to boot directly to the first hard drive (instead of the CD drive first). 7. DHCP woes - Avoid dhcpIf you are working on a home network (or a small business network) where address lease isnt a problem, go with static IP addresses. This will keep your machine from having to call out to a dhcp server to get an IP address. If you take this approach, make sure you configure your /etc/resolve.confto reflect your DNS server addresses as well. 8. Hotplug unplugged - If you can spare it, get rid of hotplugHotplug is the system that allows you to plug in new devices and use them immediately. If you know your server wont need this system, delete it. This will cut down on boot time. On many systems, hotplugging consumes much of the boot time. Removing hotplug will vary depending upon the distribution you use. Although udev has majorly replaced hotplug. But if youre running an older distribution, this does apply.9. Initng for the daring onesThe initng system serves as a replacement for the sysvinit system and promises to drastically decrease boot times in UNIX-like operating systems. If you would like to see the initng system in action, you can give the Pingwinek livecd a try. 10. HackerPunk - Use a hack with DebianIf youre using Debian, there is a simple hack you can use to switch your startup scripts to run in parallel. If you look at the/etc/init.d/rcscript, you will see:CONCURRENCY=nonearound line 24. Change this line toCONCURRENCY=shelland you should see a reduction in boot times.
