[125005100010] |Performance tuning with System Control (sysctl) in Ubuntu
[125005100020] |The Linux kernel is flexible, and you can even modify the way it works on the fly by dynamically changing some of its parameters using sysctl command.
[125005100030] |Sysctl provides an interface that allows you to examine and change several hundred kernel parameters in Linux or BSD.
[125005100040] |Changes take effect immediately, and there’s even a way to make them persist after a reboot.sysctl is used to modify kernel parameters at runtime.
[125005100050] |The parameters available are those listed under /proc/sys/.
[125005100060] |Procfs is required for sysctl support in Linux.
[125005100070] |You can use sysctl to both read and write sysctl data.Many of the tunable performance items can be configured directly by the kernel.
[125005100080] |The command sysctl is used to view current kernel settings and adjust them.
[125005100090] |Important Note:- Editing sysctl.conf file might break your system this is for advanced users only
[125005100100] |Procedure to follow
[125005100110] |First you need to make a backup copy of /etc/sysctl.conf file using the following command
[125005100120] |cp /etc/sysctl.conf /etc/sysctl.conf.back
[125005100130] |Now edit the /etc/sysctl.conf file
[125005100140] |sudo gedit /etc/sysctl.conf
[125005100150] |Use which is suitable for you
[125005100160] |Add the following lines to /etc/sysctl.conf if you have 512MB RAM or more
[125005100170] |kernel.sem = 250 32000 100 128 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 fs.file-max = 65536 vm.swappiness = 0 vm.vfs_cache_pressure = 50
[125005100180] |If you have a fast broadband (UL 10Mbps / DL 10Mbps, my broadband connection speed) use the following setting
[125005100190] |net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 net.ipv4.tcp_no_metrics_save = 1
[125005100200] |If you have a Wifi (such as IEEE 802.11 a/b/g) or a 3.5G modem, use the following setting
[125005100210] |net.core.rmem_default = 524288 net.core.rmem_max = 524288 net.core.wmem_default = 524288 net.core.wmem_max = 524288 net.ipv4.tcp_wmem = 4096 87380 524288 net.ipv4.tcp_rmem = 4096 87380 524288 net.ipv4.tcp_mem = 524288 524288 524288 net.ipv4.tcp_rfc1337 = 1 net.ipv4.ip_no_pmtu_disc = 0 net.ipv4.tcp_sack = 1 net.ipv4.tcp_fack = 1 net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_timestamps = 1 net.ipv4.tcp_ecn = 0 net.ipv4.route.flush = 1
[125005100220] |If you want to Prevent SYN attack use the following setting
[125005100230] |net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_max_syn_backlog = 2048 net.ipv4.tcp_synack_retries = 2
[125005100240] |If you want to Disables packet forwarding use the following setting
[125005100250] |net.ipv4.ip_forward=0
[125005100260] |Increase the maximum number of open files use the following setting
[125005100270] |fs.file-max = 100000
[125005100280] |Save and exit the file
[125005100290] |Now you need to run the following command to take your changes in to live
[125005100300] |sudo sysctl -p

[125005110010] |How to Convert .BIN/.CUE Files to .ISO in Ubuntu
[125005110020] |An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization ) format that is supported by many software vendors.
[125005110030] |ISO image files typically have a file extension of .ISO.
[125005110040] |Occasionally, you might come across a disc image in the BIN format.
[125005110050] |While there are ways to use BIN/CUE’s in Linux, it is much easier to convert them to the standard ISO format.
[125005110060] |bchunk (BinChunker)
[125005110070] |CD image format conversion from bin/cue to iso/cdrThe bchunk package contains a UNIX/C rewrite of the BinChunker program.
[125005110080] |BinChunker converts a CD image in a .bin/.cue format (sometimes .raw/.cue) into a set of .iso and .cdr/.wav tracks.
[125005110090] |The .bin/.cue format is used by some non-UNIX CD-writing software, but is not supported on most other CD-writing programs.
[125005110100] |Install bchunk using the following command
[125005110110] |sudo aptitude install bchunk
[125005110120] |This will complete the installation.
[125005110130] |Using bchunk
[125005110140] |bchunk syntax
[125005110150] |bchunk [-v] [-p] [-r] [-w] [-s]
[125005110160] |Available options
[125005110170] |-v - Makes binchunker print some more unnecessary messages, which should not be of interest for anyone.
[125005110180] |-w - Makes binchunker write audio tracks in WAV format.
[125005110190] |-s - Makes binchunker swap byte order in the samples of audio tracks.
[125005110200] |-p - Makes binchunker go into PSX mode and truncate MODE2/2352 tracks to 2336 bytes at offset 0 instead of normal 2048 bytes at offset 24.
[125005110210] |-r - Makes binchunker output MODE2/2352 tracks in raw format, from offset 0 for 2352 bytes.
[125005110220] |Good for MPEG/VCD.
[125005110230] |Bchunk Example
[125005110240] |bchunk IMAGE.bin IMAGE.cue IMAGE.iso
[125005110250] |Using CDemu
[125005110260] |You can also use CDemu to do this and the ubuntu ppa as follows
[125005110270] |deb http://ppa.launchpad.net/cdemu/ubuntu hardy main deb-src http://ppa.launchpad.net/cdemu/ubuntu hardy main

[125005160020] |I have collected some common problems and solutions for Nvidia restricted drivers after Ubuntu 8.10 (Intrepid Ibex) Upgrade.I really thank for those users and ubuntu forum members who posted the solutions.I hope this will be useful for some users to fix their problems.
[125005160030] |Problem 1
[125005160040] |upgrade to 8.10 - can’t enable Nvidia restricted drivers
[125005160050] |Upgraded from 8.04.1 to 8.10 (x64).
[125005160060] |GF 7600GT.
[125005160070] |Athlon X2 64.
[125005160080] |Starts up using the unaccelerated drivers.
[125005160090] |Using ‘Hardware Drivers’ I try to enable the 177 driver, get error dialog: “Reconfiguring X.org video drivers is not possible: /etc/X11/xorg.conf if invalid”
[125005160100] |- tried deleting xorg.conf
[125005160110] |- tried dpkg-reconfig xserver-xorg
[125005160120] |- tried nvidia-xconfig
[125005160130] |None of these work.
[125005160140] |- /var/log/Xorg.0.log doesn’t show any syntax errors with any of these xorg.conf files.
[125005160150] |Any ideas?
[125005160160] |Solution
[125005160170] |1) Open Synaptic Package Manager
[125005160180] |2) Search nvidia
[125005160190] |3) Installed all the 177 that are not yet installed (except those with the -dev suffix) or run this command to install drivers sudo apt-get install nvidia-
[125005160200] |glx-177
[125005160210] |4) Made sure nvidia-settins is installed as well
[125005160220] |5) Restarted
[125005160230] |6) Went to “Hardware Drivers”
[125005160240] |7) Activated 177
[125005160250] |Run the following command to set the nvidia card settings
[125005160260] |gksudo nvidia-settings
[125005160270] |Problem 2
[125005160280] |nvidia-settings segmentation fault.In the nvidia-settings menu (System->Administration->NVIDIA X Server Settings), if I click “Save to X Configuration File” (in the “X Server Display Configurations” page), the window closes.
[125005160290] |This was not the behavior in Ubuntu 8.04.
[125005160300] |If I open the menu from the command line, then clicking “Save to X Configuration File” will print “Segmentation fault” before the window closes.
[125005160310] |This happens whether or not I use sudo when executing nvidia-settings.
[125005160320] |Solution
[125005160330] |I heard that the new X.Org was going to rely less on the xorg.conf file, but it still exits.
[125005160340] |I can still apply my desired changes by clicking “Apply”, so I personally do not have any problems.
[125005160350] |I am wondering if the segfault is a bug.
[125005160360] |I renamed my xorg.conf file to something radically different: xorg_conf_backup.txt Then, when I had nvidia-settings save to xorg file, it asked where it was.
[125005160370] |I just pointed it to the same location (/etc/X11/xorg.conf) and had it make a new one.
[125005160380] |That seemed to make it stick.
[125005160390] |It seems unhappy in having to deal with existing xorg files.
[125005160400] |Problem 3
[125005160410] |How to get 1920×1200 Resolution Dell 2405fwp Nvidia 6150se

[125005160460] |1. Isntall the restricted drivers System ---> Hardware Drivers
[125005160470] |2. Select the recommended drivers, install and reboot.
[125005160480] |3. Backup the original /etc/X11/xorg.conf:
[125005160490] |$ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.org
[125005160500] |4. Edit /etc/X11/xorg.conf:

[125005160520] |5. look for the Section “Monitor”
[125005160530] |add the following lines[DO NOT CHANGE ANYTHING ELSE]:
[125005160540] |HorizSync 30-81 VertRefresh 60
[125005160550] |6. look for Section “Screen”
[125005160560] |add the following lines[DO NOT CHANGE ANYTHING ELSE]:
[125005160570] |SubSection “Display” Depth 24 Modes “1920x1200_60″ EndSubSection
[125005160580] |7. Then do: $ sudo nvidia-settings

[125005160600] |8. Saving the X configuration File [while nvidia-settings is still open]:
[125005160610] |$ sudo rm /etc/X11/xorg.conf
[125005160620] |save file as /etc/X11/xorg.conf
[125005160630] |9. edit /etc/X11/xorg.conf if needed be repeat 5 &6
[125005160640] |10. then Reboot and press the autosize button on the LCD
[125005160650] |And here is a copy of my working xorg.conf file:

[125005160710] |Ubuntu 8.10 My Graphics can’t be enabled. nVidia Go 7400 graphics card
[125005160720] |Solution
[125005160730] |I got mine working by going to System->Administration->Hardware Drivers.
[125005160740] |However, the two options presented to me are the 173 and 177 drivers, so that might not help you.
[125005160750] |The 177 driver, which was also recommended, worked.
[125005160760] |After activating that driver, I edited the display setting with System->Administration->NVIDIA X Server Settings and then clicked Apply.
[125005160770] |Problem 5 (Intrepid blank screen problem)
[125005160780] |I wanted to install the Intrepid Ibex [8.10] upgrade.
[125005160790] |Today I started the Update Manager and let it upgrade to 8.10.
[125005160800] |Downloading the Binaries took 5-odd hours[I'm on a 384Kbps connection and the download size is just a mite less than 1GB].It took an hour to install and asked to reboot.
[125005160810] |This is where the troubles started.
[125005160820] |After rebooting, it went to the beige screen that precedes the splash screen and then to a black blank screen.
[125005160830] |I could move around the mouse and that was it.

[125005161100] |Install NVIDIA XFX 8600 GT in Ubuntu 8.10
[125005161110] |My machine is MSI RS-480-IL2 motherboard, with NVIDIA XFX 8600 GT card.
[125005161120] |This is the procedure I followed:
[125005161130] |Just go to System -> Adminitration-> Hardware Drivers and enable NVIDIA 177 driver.
[125005161140] |It will download and install the driver.
[125005161150] |Here there is a small hitch.
[125005161160] |Sometimes the download progress window stops at 0% only, it is bug, but the download takes place in the background and installs the driver.
[125005161170] |You need to be patient for about 5 minutes (256 KBPS download speed).
[125005161180] |After that, just check under System -> Administration for a new menu entry “NVIDIA Settings”, if so, the driver is installed.
[125005161190] |If you select the menu item, it will say “Looks like NVIDIA driver is not being used, Update your Xorg.conf file, just run “nvidia-xconfig” from terminal as root”.
[125005161200] |Do that, and it will update your xorg.conf file, just restart X, using CTRL + ALT + BACKSPACE, it will logout you out and ask for login again.
[125005161210] |Just login and you have NVIDIA 3D fully working.
[125005161220] |Try enabling 3D effects and enjoy !!!
[125005161230] |Ubuntu 8.10 really rocks, especially with 3D enabled.
[125005161240] |For all the persons who were kind enough to reply and comment on earlier post, I would like to thank all of you.
[125005161250] |Anyone facing problem with Ubuntu 8.04, I suggest upgrade to Ubuntu 8.10.
[125005161260] |It will solve many problems.

[125005170010] |Fix for Linux kernel 2.6.27 regression in Ubuntu 8.10 (Intrepid Ibex)
[125005170020] |After Yesterday (30th October 2008) Ubuntu 8.10 release a regression was discovered in Linux kernel version 2.6.27 packages.
[125005170030] |Details about Linux kernel regression
[125005170040] |Version 2.6.27 of the Linux kernel changed the order of options in TCP headers.
[125005170050] |While this change was RFC-compliant, it was found that some old routers and consumer DSL modems would not route traffic for these systems when TCP timestamps were enabled.
[125005170060] |As a workaround, TCP timestamps were disabled via sysctl.
[125005170070] |Solution
[125005170080] |The problem can be corrected by upgrading your system to the following package versions:
[125005170090] |Ubuntu 8.10:
[125005170100] |linux-image-2.6.27-7-generic 2.6.27-7.15 linux-image-2.6.27-7-server 2.6.27-7.15 linux-image-2.6.27-7-virtual 2.6.27-7.15 procps 1:3.2.7-9ubuntu2.1
[125005170110] |sudo aptitude update
[125005170120] |sudo aptitude dist-upgrade
[125005170130] |After a standard system upgrade you need to reboot your computer to effect the necessary changes.
[125005180010] |Ubucleaner - Simple bash script to keep your Ubuntu System Clean
[125005180020] |Ubucleaner is a simple bash script that help you to keep your computer clean.
[125005180030] |Note:- This is Only for advanced Ubuntu users
[125005180040] |Ubucleaner Features
[125005180050] |- Clean apt cache
[125005180060] |- Remove config files left from uninstalled .deb packages(it happens if you don’t use the --purge switch with apt-get)
[125005180070] |- Remove every kernel except the one you are using
[125005180080] |- Empty the trashes of every user(including root)
[125005180090] |It uses apt and the kernel removing thing searches for ubuntu-only packages, so it can’t work on non-debian system and the result is undetermined for other debian-based system, but you can still use the other features of the script(you’ll just have to comment the parts you don’t want).
[125005180100] |The script assumes that you are using the text-based Aptitude application, rather than apt-get and dpkg.
[125005180110] |If you are not using Aptitude, you should also replace the reference to aptitude clean with apt-get clean and the reference to aptitude purge to dpkg --purge.This can be done done by editing the following script.
[125005180120] |First you need to download the script from here or using the following command
[125005180130] |wget http://www.opendesktop.org/CONTENT/content-files/71529-ubucleaner.sh
[125005180140] |Now you should have 71529-ubucleaner.sh file you need to give execute permissions using the following command
[125005180150] |sudo chmod +x 71529-ubucleaner.sh
[125005180160] |Run the script using the following command
[125005180170] |./71529-ubucleaner.sh

[125005220020] |In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go.
[125005220030] |This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.
[125005220040] |The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications.
[125005220050] |Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of ownership.New pre-configured installation options have been added to the Ubuntu Server.
[125005220060] |Mail Server, Open SSH Server,Samba File Server, Print Server, Tomcat Java Server,Virtual Machine Host and Database Server options join existing LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.

[125005230010] |Ubuntu Server:Install GUI and Webmin in Ubuntu 8.10 (Intrepid Ibex) Guide
[125005230020] |We have already discussed how to install ubuntu 8.10 LAMP server .If you are a new user and not familiar with command prompt you can install GUI for your ubuntu LAMP server using the 2 options
[125005230030] |1) Install desktop Environment
[125005230040] |2) Install Webmin
[125005230050] |1) Install desktop Environment
[125005230060] |First you nee to make sure you have enabled Universe and multiverse repositories in /etc/apt/sources.list file once you have enable you need to use the following command to install GUI
[125005230070] |sudo apt-get update
[125005230080] |sudo apt-get install ubuntu-desktop
[125005230090] |The above command will install GNOME desktop if you want to install KDE desktop use the following command
[125005230100] |sudo apt-get install kubuntu-desktop
[125005230110] |2) Install Webmin
[125005230120] |Webmin is a web-based interface for system administration for Unix.
[125005230130] |Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more.
[125005230140] |Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.Currently There is no Webmin package in the Ubuntu repositories.This tutorial will explain how to Install Webmin in Ubuntu Intrepid Ibex
[125005230150] |You can install webmin for your server web interface to configure apache2,mysql,FTp servers and many more.Now we will see how to install webmin in Ubuntu 8.10
[125005230160] |Preparing your system
[125005230170] |First you need to install the following packages
[125005230180] |sudo aptitude install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
[125005230190] |Now download the latest webmin using the following command or from here
[125005230200] |wget http://garr.dl.sourceforge.net/sourceforge/webadmin/webmin_1.441_all.deb
[125005230210] |Now we have webmin_1.441_all.deb package install this package using the following command
[125005230220] |sudo dpkg -i webmin_1.441_all.deb
[125005230230] |This will complete the installation.
[125005230240] |Ubuntu in particular don’t allow logins by the root user by default.
[125005230250] |However, the user created at system installation time can use sudo to switch to root.
[125005230260] |Webmin will allow any user who has this sudo capability to login with full root privileges.
[125005230270] |Now you need to open your web browser and enter the following
[125005230280] |https://your-server-ip:10000/
[125005230290] |Now you should see similar to the following Screen
[125005230300] |After login if you want to configure Apache,Mysql server you need to click on Servers on your lefthand side you should many servers are ready to configure
[125005230310] |This is very Easy to configure most of the servers and Enjoy your new Ubuntu Intrepid Ibex LAMP Server.
[125005240010] |How to Change The Bootsplash In Ubuntu 8.10 (Intrepid Ibex)
[125005240020] |Bootsplash can be a simple visualisation of the scrolling boot messages in the console, but it can also present graphics or some combinations of both.For some reason there is a bug in the new version (8.10 Intrepid Ibex) that will not let you change this.
[125005240030] |When you reboot you might see a quick flash of an error saying acpid:exiting we will see how to change bootsplash in ubuntu 8.10
[125005240040] |Note :- This procedure only for Intermediate and advanced users
[125005240050] |Procedure to follow
[125005240060] |First you need to uninstall existing usplash using the following command
[125005240070] |sudo aptitude remove usplash --purge
[125005240080] |Now download the latest version of splashy files libsplashy from here and splashy from here
[125005240090] |after downloading install those two files using the following commands from your terminal or you can double click on those packages to install
[125005240100] |sudo dpkg -i libsplashy1_0.3.10-1_i386.deb
[125005240110] |sudo dpkg -i splashy_0.3.10-1_i386.deb
[125005240120] |After installing new version of splashy, you will want to edit /boot/grub/menu.lst before that take a backup of your menu.lst file
[125005240130] |sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.backup
[125005240140] |Now edit the /boot/grub/menu.lst file using the following command
[125005240150] |sudo gedit /boot/grub/menu.lst
[125005240160] |Look for your kernel boot option.In my case with the following line
[125005240170] |kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=3dca6051-5877-438c-94c5-f5ff7803d851 ro quiet splash
[125005240180] |and add vga=791 at the end of it so it reads similar to the following line
[125005240190] |kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=3dca6051-5877-438c-94c5-f5ff7803d851 ro quiet splash vga=791
[125005240200] |Save and exit the file.
[125005240210] |Update your grub using the following command
[125005240220] |sudo update-grub
[125005240230] |Now you need to reboot your system, and you should see a new splashy splash screen on you ubuntu 8.10 system.This is just a workaround.
[125005240240] |If you know of a way to fix usplash in Ubuntu 8.10 please share with us.
[125005250010] |How to Use Remote Desktop in Ubuntu 8.10 (Intrepid Ibex)
[125005250020] |In this tutorial we will see how to enable remote desktop access in ubuntu desktop and accessing remotely.vino is VNC server for GNOME.VNC is a protocol that allows remote display of a user’s desktop.
[125005250030] |This package provides a VNC server that integrates with GNOME, allowing you to export your running desktop to another computer for remote use or diagnosis.
[125005250040] |By default ubuntu will come with vino-server so it is very easy to configure to enable remote desktop sharing in your ubuntu machine.If you want to access ubuntu machine remotely you need to login in to your ubuntu system.
[125005250050] |Important note :-Remote Desktop will only work if there’s a GNOME login session.Leaving your computer with an unattended GNOME login session is not secure and not recommended.
[125005250060] |Enable Remote Desktop in Ubuntu
[125005250070] |First you need to go to System -> Preferences -> Remote Desktop
[125005250080] |Once it opens you should see similar to the following screen
[125005250090] |![]()
In the above screen you need to configure remote desktop preferences for sharing and security
[125005250100] |For Sharing
[125005250110] |you need to tick the box next to the following two options
[125005250120] |Allow other users to view your desktop
[125005250130] |Allow other users to control your desktop
[125005250140] |For Security
[125005250150] |you need to tick the box next to the following two options
[125005250160] |Ask you for confirmation (If you tick this option some one need to click on allow from remote desktop once it connected if you don’t want you can untick this option)
[125005250170] |Require the user to enter this password:
[125005250180] |Password: Specify the password
[125005250190] |![]()
Now you need to click on Advanced Tab select your options click on close
[125005250200] |For Network
[125005250210] |Only allow local connections
[125005250220] |Use an alternative port
[125005250230] |Disable the wallpaper when connected
[125005250240] |For Security
[125005250250] |Require encryption
[125005250260] |Lock Screen on disconnect
[125005250270] |For Notification Area

[125005260010] |ccd2iso - Convert CloneCD disc image (.img) format to standard ISO (.iso)
[125005260020] |If you want to convert .img to .iso file you need to use ccd2iso.This converts CD backup files created using the non-free CloneCD program to a format understood by most Free Software CD writing programs.
[125005260030] |ccd2iso converts FOO.IMG to ISO format and writes the result to BAR.ISO.If fewer arguments than expected are given,ccd2iso will print its help message and quit.
[125005260040] |If more arguments than expected are given,ccd2iso will silently ignore them and use only the first two arguments.
[125005260050] |IMG files are raw-data copies of optical media,generated primarily by the Windows application CloneCD, and are primarily used to store CDs with odd properties,such as sectors which need to have read errors when read.
[125005260060] |Conversion to ISO format removes this information,as ISO format does not support this.
[125005260070] |IMG files almost always include a SUB file, which contains additional data for the disc format, and a CCD file, which is a plaintext configu-ration file describing the disc layout.ccd2iso does not make use of these files, but the applications which generate them expect them to have the same FOO prefix as the IMG file.
[125005260080] |Install ccd2iso in ubuntu
[125005260090] |sudo aptitude install ccd2iso
[125005260100] |This will complete the installation.
[125005260110] |ccd2iso Syntax
[125005260120] |ccd2iso [FOO.IMG] [BAR.ISO]

[125005270010] |How to get Atheros AR5007EG or AR242x wireless cards (may be other models) working in Ubuntu 8.10 (Intrepid Ibex)
[125005270020] |This tutorial will explain how to Atheros AR5007EG or AR242x wireless cards working in Ubuntu 8.10 (Intrepid Ibex).First you need to compile latest ath5k driver using the following procedure.Use one of the following method.
[125005270030] |Preparing your system
[125005270040] |sudo aptitude install build-essential
[125005270050] |This will install all the required compilers.
[125005270060] |Method 1
[125005270070] |Now you need to download the latest wireless drivers from here using the following command
[125005270080] |wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
[125005270090] |Now you have compat-wireless-2.6.tar.bz2 file you need to extract this file using the following command from the terminal
[125005270100] |sudo tar -jxvf compat-wireless-2.6.tar.bz2
[125005270110] |Move to the directory you extracted in terminal
[125005270120] |cd directoryname
[125005270130] |Run the following commands
[125005270140] |make
[125005270150] |sudo make install
[125005270160] |sudo make unload
[125005270170] |sudo make load
[125005270180] |Uninstall drivers
[125005270190] |If you want to uninstall cd in to the wireless drivers directory path and use the following commands
[125005270200] |sudo make unload
[125005270210] |sudo make uninstall
[125005270220] |Method 2
[125005270230] |if you are on Intrepid and still cannot use wifi with an Atheros card , you need to do two things, 1) install linux-backport-modules and 2) blacklist ath_pci and ath_hal.
[125005270240] |To install the backport modules, just search for it on Synaptic or use apt-get or aptitude, it’s called linux-backports-modules-intrepid.
[125005270250] |Then on System/Administration/Hardware Drivers make sure Atheros driver is activated.
[125005270260] |sudo aptitude install linux-backports-modules-intrepid
[125005270270] |For Jaunty Users run the following comamnd
[125005270280] |sudo apt-get install linux-backports-modules-jaunty
[125005270290] |To blacklist the old modules, do this:
[125005270300] |gksudo gedit /etc/modprobe.d/blacklist
[125005270310] |And add the following lines At the bottom of the file save and exit
[125005270320] |blacklist ath_hal blacklist ath_pci
[125005270330] |Now you need to reboot your system.
[125005270340] |IF after this steps you still cannot make it work, you probably have something left still blacklisting ath5k, thus making it not to load.
[125005270350] |You should search all the files on /etc/modprobe.d for all lines that had:
[125005270360] |blacklist ath5k
[125005270370] |And add a # before the start of the line, thus making it into a comment so the above one becomes
[125005270380] |# blacklist ath5k
[125005270390] |Save and exit the file
[125005270400] |I hope this help for some one to fix their wireless problem.
[125005280010] |Execute commands simultaneously on multiple servers Using PSSH/Cluster SSH/Multixterm
[125005280020] |If you have multiple servers with similar or identical configurations (such as nodes in a cluster), it’s often difficult to make sure the contents and configuration of those servers are identical.
[125005280030] |It’s even more difficult when you need to make configuration modifications from the command line, knowing you’ll have to execute the exact same command on a large number of systems .
[125005280040] |In this tutorial we will see some tools to execute one command on multiple remote servers using ssh.First you need to make sure you have ssh installed in your machine or you can install using the following command
[125005280050] |sudo aptitude install ssh
[125005280060] |Now we are going to see the following tools which does the required job we are looking for
[125005280070] |1) Pssh
[125005280080] |2) cluster ssh
[125005280090] |3) Multixterm
[125005280100] |1) Pssh
[125005280110] |pssh provides a number of commands for executing against a group of computers, using SSH.
[125005280120] |It’s most useful for operating on clusters of homogenously-configured hosts.
[125005280130] |The package contains:
[125005280140] |- Parallel ssh (parallel-ssh, upstream calls it pssh), executes commands on multiple hosts in parallel
[125005280150] |- Parallel scp (parallel-scp, upstream calls it pscp), copies files to multiple remote hosts in parallel
[125005280160] |- Parallel rsync (parallel-rsync, upstream calls it prsync), efficiently copies files to multiple hosts in parallel
[125005280170] |- Parallel nuke (parallel-nuke, upstream calls it pnuke), kills processes on multiple remote hosts in parallel
[125005280180] |- Parallel slurp (parallel-slurp, upstream calls it pslurp), copies files from multiple remote hosts to a central host in parallel
[125005280190] |These tools are good for controlling large collections of nodes, where faster alternatives
[125005280200] |Install pssh in Ubuntu
[125005280210] |sudo aptitude install pssh
[125005280220] |pssh Syntax
[125005280230] |pssh command -h hosts-file options
[125005280240] |-h --hosts hosts file (each line “host[:port] [user]“) -l --user username (OPTIONAL) -p --par max number of parallel threads (OPTIONAL) -o --outdir output directory for stdout files (OPTIONAL) -t --timeout timeout in seconds to do ssh to a host (OPTIONAL) -v --verbose turn on warning and diagnostic messages (OPTIONAL) -O --options SSH options (OPTIONAL)
[125005280250] |where the hosts-file contains a list of all the hosts that you want to have the command executed on.
[125005280260] |pssh Examples
[125005280270] |The following example runs hostname on three machines (IPs or hostnames) specified in the file ips.txt using login irb2 and saves the output in /tmp/foo.
[125005280280] |sudo cat ips.txt 128.112.152.122 18.31.0.190 128.232.103.201
[125005280290] |sudo pssh -h ips.txt -l irb2 -o /tmp/foo hostname
[125005280300] |Success on 128.112.152.122:22 Success on 18.31.0.190:22 Success on 128.232.103.201:22
[125005280310] |sudo ls /tmp/foo
[125005280320] |128.112.152.122 128.232.103.201 18.31.0.190
[125005280330] |sudo cat /tmp/foo/*
[125005280340] |planetlab-1.cs.princeton.edu planetlab1.xeno.cl.cam.ac.uk planetlab1.lcs.mit.edu
[125005280350] |By default, pssh uses at most 32 ssh processes in parallel to ssh to the various nodes.
[125005280360] |(This is somewhat important if you’re controlling hundreds or thousands of machines.)
[125005280370] |By default, it also uses a timeout of one minute to ssh to a node and obtain a result.
[125005280380] |For ssh commands that take longer than this (e.g., sleep 61), the -t option can be used.
[125005280390] |Note that pssh and pnuke have a default timeout of one minute. pscp and prsync have no default timeout, but one can be specified using the -t option.
[125005280400] |pscp
[125005280410] |Here’s an example of using pscp to copy files in parallel to a set of machines.
[125005280420] |sudo pscp -h ips.txt -l irb2 /etc/hosts /tmp/hosts
[125005280430] |Success on 128.112.152.122:22 Success on 18.31.0.190:22 Success on 128.232.103.201:22
[125005280440] |Using the -r option will perform a recursive copy for copying entire directories.
[125005280450] |2) cluster ssh
[125005280460] |administer multiple ssh or rsh shells simultaneouslyClusterSSH allows you to control multiple ssh or rsh sessions from a single input window.
[125005280470] |You can also configure clusters of machines for easy invocation and interact with individual terminal windows during a session.
[125005280480] |Install Cluster ssh in Ubuntu
[125005280490] |sudo aptitude install clusterssh
[125005280500] |Configuration Files
[125005280510] |This /etc/clusters file is cluster tag database.
[125005280520] |Contains a list of tags and hostnames, in the form
[125005280530] | [@]hostname [...]
[125005280540] |Newlines and comments (delimited with a #) are ignored.
[125005280550] |Cluster definitions can also be added to the $HOME/.csshrc file
