Unofficial Ubuntu 6.10 (Edgy Eft) Starter Guide

As Ubuntu 6.10 (Edgy Eft) has just been released, this guide is still a work in progress. Your help in testing and perfecting this guide is needed.

This guide was started by Chua Wen Kiat (Kuala Lumpur, Malaysia). It is now being maintained by the Linux Center of University of Latvia, and everyone else who is willing to contribute.

This guide can be discussed at the official UbuntuGuide.org Forum at ubuntuforums.org. Stop by and join the discussion.

Pagrindinės pastabos

  1. Tai yra Neoficialus Ubuntu 6.10 (Edgy Eft) naudotojo žinynas. Jis yra tiesiogiai nesusijęs su Ubuntu ir Canonical Ltd.
  2. Apie šį žinyną jūs galite diskutuoti oficialiame UbuntuGuide.org Forume ubuntuforums.org.
  3. Jei jūs matote tekstą mėlynesniame lange, tai reiškia jog tai turi būti įvykdoma Terminalo režime (Applications -> Accesories -> Terminal).
  4. Norėdami išvengti rašybos klaidų tekstą žymėkite, kopijuokite ir įdėkite (dešiniu pelytės klavišu -> "Copy" arba "Paste". Taip pat galite naudoti Ctrl+C kopijavimui arba Shift+Insert įdėjimui)
  5. "sudo" reiškia supervartotojo (root) režimą. Greičiausiai "sudo" paprašys "Password:". Įveskite savo vartotojo slaptažodį
  6. Jeigu norite daugiau informacijos apie komandą - pasinaudokite "man" žinynu. Pavyzdžiui, "man sudo" išves žinyną apie "sudo" komandą.
  7. Jeigu pavargstate visą laiką naudotis "apt-get" komanda, skaitykite #How to apt-get the easy way (Synaptic)
  8. "apt-get" ir "wget" reikalauja prisijungimo prie Interneto, kad įdiegti/atnaujinti/atsisiūsti programas
  9. Norėdami atsisiūsti bylą spustelėkite dešiniu pelytės klavišu ant nuorodos -> Pasirinkite "Save Link As..." -> Įsitikinkite, jog bylos pavadinimas ir plėtinys yra teisingi
  10. Jeigu norite padėti verčiant Ubuntu į jūsų kalbą ar kitaip prisidėti prie Ubuntu - apsilankykite https://launchpad.net/
  11. Tegu "žmogiškumo kitiems" dvasia visada būna su jumis...


Jeigu naudojate 64-bit platformą pakeiskite visur "i386" į "amd64"

  • Skaitykite #Pagrindinės pastabos
  • Easy Ubuntu yra maža pagalbinė programa, leidžianti naujokams lengvai įdiegti daugelį ivairių programų, kaip Media Kodekus, šriftus, Macromedia Flash ir Sun Java.

Paleiskite Terminal režimą Menu -> Accessories -> Terminal ir įvykdykite šias komandas 

wget http://easyubuntu.freecontrib.org/files/easyubuntu-3.023.tar.gz
tar -zxf easyubuntu-3.023.tar.gz
cd easyubuntu
cp packagelist-dapper.pot packagelist-edgy.pot

sudo python easyubuntu.in
  • Easy Ubuntu programos lange pasirinkite tai, ką norite atsisiūsti ir įdiegti į Ubuntu.
  • Pastaba: Ankstesnes nei EasyUbuntu 3.0 versijos vartotojai gali gauti klaidas diegdami Flash ir Java.
  • Jeigu norite automatizuotų atnaujinimu - sekite šias instrukcijas:

priklausomai nuo jūsų naudojamos Ubuntu versijos:

Ubuntu: 

sudo gedit /etc/apt/sources.list

Kubuntu: 

sudo kate /etc/apt/sources.list

Atsidariusioje tekstiniame redaktoriuje /etc/apt/sources.list bylos apačioje įrašykite: 

deb http://easyubuntu.cafuego.net main easyubuntu

Nuo šiol EasyUbuntu bus automatiškai atnaujinamas.

Kaip įdiegti Automatix2 į Ubuntu, Kubuntu, and Xubuntu

  • Skaitykite #Pagrindinės pastabos
  • Automatix2 yra tas pats Automatix suprogramuotas naudojant python programavimo kalbą, tačiau su geresne vartotojo sąsaja ir geresniu įvairių programų įdiegimo palaikymu Ubuntu/Kubuntu/Xubuntu terpėje.
  • Pastaba: Prieš įdiegdami tam tikrus kodekus, turėkite omenyje, jog jie yra uždrausti kai kuriose šalyse. Pries įdiegdami juos - įsitikinkite, jog nepažeidžiate tos šalies teisinių aktų. 
sudo gedit /etc/apt/sources.list
  • Įrašykite šias eilutes bylos apačioje 
## Automatix repo
deb http://www.getautomatix.com/apt edgy main
  • PASTABA: Kubuntu/Xubuntu vartotojai turi panaikinti komentarą (pašalinti # prieš "deb" žodį) pries visus papildomus šaltinius, kad galėtų pridėti Automatix repozitoriją.
  • Gaukite GPG raktą 
wget http://www.getautomatix.com/apt/key.gpg.asc
gpg --import key.gpg.asc
gpg --export --armor 521A9C7C | sudo apt-key add -
  • Atnaujinkite APT 
sudo apt-get update
  • Įvykdykite šias komandas, norėdami įdiegti Automatix2 
sudo apt-get install automatix2
  • Automatix2 gali būti paleidžiamas taip 
Menu -> System -> Automatix
  • Automatix2 taip pat galima paleisti iš Terminal režimo, įvykdžius komandą 
automatix2

Kitas automatizuotas būdas įdiegti papildomas programas

sh install.sh

Daugiau informacijos apie šį įdiegimo būdą galite rasti http://www.iki.fi/kuparine/comp/ubuntu/install.html

Kaip įdiegti J2SE Runtime Environment (JRE) su Mozilla Firefox įskiepiu

Pastaba: Programa įtraukta į Automatix2. Jeigu jūs naudojotės Automatix2, gali būti jog ši programa jau įdiegta 

sudo apt-get install sun-java5-jre sun-java5-plugin
  • Kai paklaus - sutikite su DLJ licencija.
  • Norėdami sukonfigūruoti J2SE kaip numatytają JVM (reikalinga programoms kaip Frostwire, RSSOwl ir Mozilla Firefox įskiepiui): 
sudo update-alternatives --config java

Tada pasirinkite opciją atitinkančią J2SE (paprastai 3-ia opcija).

Kaip įdiegti JRE v5.0 Update 9

Pastaba: Programa įtraukta į Automatix2. Jeigu jūs naudojotės Automatix2, gali būti jog ši programa jau įdiegta 

Pasirinkite "Java Runtime Environment (JRE) 5.0 Update 9" ir spauskite "Download"
Sutikite su Licencija 
Atsisiūskite "Linux self-extracting file"
  • Įdiekite reikalingus įrankius : 
sudo apt-get install java-package
  • Sukurkite Ubuntu paketą : 
fakeroot make-jpkg jre-1_5_0_09-linux-i586.bin
  • Įdiekite gautą paketą : 
sudo dpkg -i sun-j2re1.5_1.5.0+update09_i386.deb


  • Perleiskite iš naujo Mozilla Firefox
  • Jeigu gavote klaidą, pabandykite pakeisti 09 bylos pavadinime į artimą versiją.

Kaip įdiegti Java Development Kit (JDK) v5.0 

sudo apt-get install sun-java5-jdk
  • Sutikite su licencijos salygomis.
  • Nustatykite Sun JVM kaip numatytają Java versiją: 
sudo update-java-alternatives -s java-1.5.0-sun
  • Pakeiskite /etc/jvm ir įrašykite /usr/lib/jvm/java-1.5.0-sun viršuje visų siūlomų JVM: 
gksudo gedit /etc/jvm

Kaip įdiegti Flash Player (Macromedia Flash) Mozilla Firefox įskiepį 

sudo apt-get install flashplugin-nonfree
sudo update-flashplugin

Pastaba: jeigu gavote klaidą, jog paketas nerastas, pabandykite Gnash (GNU Flash pakaitalas) 

sudo apt-get install libflash-mozplugin
  • Perkraukite Mozilla Firefox


Pastaba: jeigu firefox "nulūžta" apsilankius svetainėse su flash turiniu: 

sudo gedit /usr/bin/firefox

ir įrašykite šią eilutę kaip paskutinę bylos pabaigoje: 

export XLIB_SKIP_ARGB_VISUALS=1

Dabar firefox neturėtų "lūžinėti". (Launchpad klaidos ataskaita: [1])

  • Perkraukite Mozilla Firefox


Pastaba: jeigu negirdite garso Flash Player programoje (pavyzdžiui YouTube puslapyje): 

sudo apt-get install alsa-oss
gksudo gedit /etc/firefox/firefoxrc

Pakeiskite: 

FIREFOX_DSP=""

Į: 

FIREFOX_DSP="aoss"
  • Perkraukite Mozilla Firefox. Dabar neturėtų būti problemų su garsu Flash Player programoje.

Kaip įdiegti PDF skaitymo programą (Adobe Reader) su papildiniu Mozilla Firefox 

sudo apt-get install acroread mozilla-acroread acroread-plugins
  • Applications -> Office -> Adobe Reader
  • Iš naujo paleiskite Mozilla Firefox

P.S.: Adobe Reader 7.0 nepasileis jei SCIM yra vykdoma. Jūs vykdote SCIM jei esate įdiegę kitą kalbą su System -> Administration -> Language Support. Norėdami tai pakeisti (apeiti), darykite taip: 

gksudo gedit /usr/bin/acroread

Pakeiskite: 

#!/bin/sh
#

Į: 

#!/bin/sh
#
GTK_IM_MODULE=xim

Išsaugokite failą. Dabar Adobe Reader 7.0 turėtų veikti.

How to install Windows Applications in Linux (Wine)

Wine Is Not an Emulator. Wine is an Open Source implementation of the Windows API on top of X and Unix. Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available.

In other words, Wine will let you run Windows applications in Linux.

  • First, add repository for Wine: 
gksudo gedit /etc/apt/sources.list
  • Add the following lines at the end of this file 
# Repository for wine
deb http://wine.budgetdedicated.com/apt dapper main
deb-src http://wine.budgetdedicated.com/apt dapper main
  • Save the edited file 
sudo apt-get update

  • Replace everything with the following lines 
# GDM Configuration Customization file.
#
# This file is the appropriate place for specifying your customizations to the
# GDM configuration.   If you run gdmsetup, it will automatically edit this
# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration.  Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
# 
# To hand-edit this file, simply add or modify the key=value combination in
# the appropriate section in the template below.  Refer to the comments in the
# gdm.conf file for information about each option.  Also refer to the reference
# documentation.
# 
# If you hand edit a GDM configuration file, you should run the following
# command to get the GDM daemon to notice the change.  Any running GDM GUI
# programs will also be notified to update with the new configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# For example, the "Enable" key in the "[debug]" section would be specified by
# "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings.  You can also restart GDM by sending
# a HUP or USR1 signal to the daemon.  HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
# 
# For full reference documentation see the gnome help browser under
# GNOME|System category.  You can also find the docs in HTML form on
# http://www.gnome.org/projects/gdm/

Activate side-mouse-buttons in FireFox

Just add two lines to xorg.conf will activate side-mouse-buttons in FireFox. This should work with most 5-button mouse. Here is a list of mice that worked with this instruction.

  • Logitech MX510
  • Logitech MX518
  • Logitech MX700
  • Intellimouse Explorer (first edition)


Backup Gnome configuration file 

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Modify the Gnome configuration file 

gksudo gedit /etc/X11/xorg.conf

Find the Input Device section for your mouse and add two lines as shown below. You may also increase the number of buttons if your mouse has more than 7, just fix the rest of the section based upon the number of buttons (remember back/forward, wheel click & tilt left/right all count as buttons)

Change: 

Section "InputDevice"
	Identifier "Configured Mouse"
	Driver "mouse"
	Option "CorePointer"
	...
	Option "Protocol" "ExplorerPS/2"
	...
	Option "Emulate3Buttons"       "true"
EndSection

to: 

Section "InputDevice"
	Identifier "Configured Mouse"
	Driver "mouse"
	Option "CorePointer"
	...
	Option "Protocol" "ExplorerPS/2"
	...
	Option "Emulate3Buttons"       "true"
	Option "Buttons" "7"
 	Option "ButtonMapping" "1 2 3 6 7"
EndSection


At this point you can reboot your computer or reboot Gnome (Ctrl-Alt-BackSpace) to see if your forward/back buttons work in FireFox. They still won't work in Nautilus yet until you install the imwheel dameon.

How to setup pivot (screen rotation) with default X.org NVIDIA drivers

  • Some LCD monitors are equipped with the pivot feature, to take advantage of it the display has to be rotated 90 degrees. The default nVidia drivers shipped with X.org ("nv") support software screen rotation. Note that it's unaccelerated and can be slow, read #How to install Graphics Driver (NVIDIA) if you decide to install the proprietary driver.
  • To rotate the screen find the "Device" section for the "nv" driver in the /etc/X11/xorg.conf file: 
Section "Device"                                                                
       Identifier      "NVIDIA Corporation NV34 [GeForce FX 5200]"
       Driver          "nv"
  • Add the following options to this section: 
       Option "Rotate" "CW"

Where the "Rotate" option has two possible values (depending on the orientation of the monitor):

  1. CW - rotate the display clockwise (right).
  2. CCW - rotate the display counterclockwise (right).

How to setup pivot (screen rotation) with proprietary NVIDIA drivers

  • Some LCD monitors are equipped with the pivot feature, to take advantage of it the display has to be rotated 90 degrees. The proprietary nVidia drivers support hardware rotation with the Xrandr extension.
  • To enable rotation support find the "Device" section for the "nvidia" driver in the /etc/X11/xorg.conf file: 
Section "Device"                                                                
       Identifier      "NVIDIA Corporation NV34 [GeForce FX 5200]"
       Driver          "nvidia"
  • Add the following option to this section: 
       Option          "RandRRotation" "on"
  • Then the display can be rotated (direction depends on the orientation of the monitor) by:
  1. Setting the "Rotation" property to either "Left" or "Right" in the "System > Preferences > Screen Resolution" dialog.
  2. Issuing either "xrandr -o left" or "xrandr -o right" command.

How to Correct the Graphics Resolution (Intel)

  • Intel 915g, 945g, etc. graphics chipsets only have a limited set of resolutions initially installed, despite the correct driver being detected.
  • Install the resolution altering tool: 
sudo apt-get install 915resolution
  • Run the following to see the availible modes: 
915resolution -l
  • Choose a resolution you don't need and replace, for example the following changes 1920x1440 to 1920x1200 
915resolution 5c 1920 1200
  • This should add the option for that resolution to the "System>Preferences>Screen Resolution" tool.
  • If it works correctly then you can make the change permanent: 
sudo gedit /etc/rc.local
  • Simply add the command you typed in above before: 
exit 0

How to detect CPU temperature, fan speeds and voltages (lm-sensors) 

sudo apt-get install lm-sensors

Create file called mkdev.sh, and paste in the following 

#!/bin/bash

# Here you can set several defaults.

# The number of devices to create (max: 256)
NUMBER=32

# The owner and group of the devices
OUSER=root
OGROUP=root
# The mode of the devices
MODE=600

# This script doesn't need to be run if devfs is used
if [ -r /proc/mounts ] ; then
if grep -q "/dev devfs" /proc/mounts ; then
echo "You do not need to run this script as your system uses devfs."
exit;
fi
fi

i=0;

while [ $i -lt $NUMBER ] ; do
echo /dev/i2c-$i
mknod -m $MODE /dev/i2c-$i c 89 $i || exit
chown "$OUSER:$OGROUP" /dev/i2c-$i || exit
i=$[$i + 1]
done
#end of file

Make this file executable, then run it 

sudo chmod +x mkdev.sh
./mkdev.sh

Now detect sensors, and answer "y" to all questions. 

sudo sensors-detect

Load the modules into kernel 

sensors -s

Now, let's see the output

               log_success_msg "  restart, force-reload - starts a new system-wide fancontrol service"
               exit 1
               ;;
esac

exit 0

Make it excutable 

sudo chmod +x /etc/init.d/fancontrol

Test it 

/etc/init.d/fancontrol start

and 

/etc/init.d/fancontrol stop

If it works fine, autoload it when you reboot. Insert the following line into /etc/rc.local, before "exit 0"

How to monitor CPU, GPU temperatures, fan speeds and voltages (GKrellM)

  • Install hddtemp first to monitor hard drive temperatures 
sudo apt-get install hddtemp

GKrellM is a hardware monitor that can display CPU and GPU temperatures, fan speeds, voltages, CPU load, network load, disk activity, disk temperature, memory usage, and swap usage. The installation is very easy, and configuration is just a few mouse-clicks. You can set alerts to warn you if the CPU is too hot or there is a fan failure. The hddtemp utility works with GKrellM to allow it to sense the disk temperature, as keeping your disks cool (e.g. less than around 40C) will allow them to last longer than if they run continually at higher temperatures (e.g. above 50C). 

sudo apt-get install gkrellm

To run the program 

Click Applications -> System Tools -> GKrellM

To configure the settings, 

Right click on GKrellM -> Configuration

I was struggling with lm_sensors before, but it doesn't detect all of the sensors on my computer. Later I found "GKrellM". It displays the GPU temperature on my nVidia 6600 GT out of the box. GKrellM also has plugins that show weather info, set reminders, etc.

Add an audio alert (optional Step): Here is how to play an audio message when the CPU is too hot or a fan fails. First you need to find or record your own audio alert files. (I use Audacity to record my own.) Then go to: 

Configuration -> Builtins folder (Left side)-> Sensors -> Temperatures folder (Right side)-> CPU -> Alerts Button

Paste ONE of the following lines into a Terminal window first to test the sound. If you have two sound cards, you can use "-ao oss:/dev/dsp1" option to route the sound to the second sound card. Modify the file path and name so it points to the correct file. If you can hear the sound, then copy that line to a command line text field on the GKrellM's Alerts window. 

mplayer /home/myfolder/alert_messages/heat_alert.mp3
mplayer -ao oss:/dev/dsp1 /home/myfolder/alert_messages/heat_alert.mp3

How to install Windows Wireless Drivers (Ndiswrapper)


  • Find out if you have acx module loaded. Because acx module interferes with windows driver, we need to remove it if it is found. 
lsmod | grep acx
  • Remove the acx module if found. It could also be acx_pci or similar. Please Note: New kernel updates will auto load the acx module again. So repeat the following two commands every time the kernel is updated. 
sudo rmmod acx
sudo mv /lib/modules/2.6.15-26-386/kernel/drivers/net/wireless/acx /root/
  • Install ndiswrapper and drivers 
sudo apt-get install ndiswrapper-utils
sudo ndiswrapper -i /location_of_your_wireless_driver/your_driver.inf
sudo ndiswrapper -l
sudo modprobe ndiswrapper
  • Set ndiswrapper to load on startup 
sudo ndiswrapper -m
gksudo gedit /etc/modules
  • Add the following module to the list 
ndiswrapper
  • Now you can configure your wireless card with ifconfig and iwconfig.
e.g. Supposing wlan0 is your wireless device. 
sudo iwconfig wlan0 essid "AP" key ababababababababab mode Managed
iwconfig
  • You sould now be able to see the MAC address of the access point and signal rate.

How to enable WPA with Ndiswrapper driver

  • First, make sure the Ndiswrapper driver works by itself without encryption.
  • Create a file called /etc/wpa_supplicant.conf, and paste in the following. Modify the ssid and psk values. 
ctrl_interface=/var/run/wpa_supplicant
 network={
   ssid="YourWiFiSSID"
   psk="YourWiFiPassword"
   key_mgmt=WPA-PSK
   proto=WPA
   pairwise=TKIP
 }
  • Test it. Make sure your router is broadcasting its SSID. 
sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd
  • If you WPA works. Load it automatically when you reboot. 
gksudo gedit /etc/network/interfaces
  • Change your wlan0 section to the following.

If you are using static IP: 

auto wlan0
iface wlan0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.1
pre-up wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant

or this, if you are using dhcp. 

auto wlan0
iface wlan0 inet dhcp
pre-up wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant

How to install a Wacom tablet

For a detailed guide with screenshots about how to configure the "Extended input devices" in your graphic applications, please follow the official Dapper guide at https://wiki.ubuntu.com//Wacom

With the version of the Linux Wacom driver (0.7.2) in Ubuntu 6.06 Dapper Drake, if you unplug you tablet, it won't function when you plug it back in and you will have to restart X. For this reason, it is best to leave the tablet plugged in. This limitation will be removed when the 0.7.4 version of the driver is included in Ubuntu.

  • 1. Using Synaptic package manager, check if the packages xserver-xorg-input-wacom and wacom-tools are already installed - if not, install them. If you prefer using the command line, you can also execute : 
     sudo apt-get install xserver-xorg-input-wacom wacom-tools
  • 2. Save a copy of your /etc/X11/xorg.conf : 
      sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
  • then edit it with the command line : 
      gksudo gedit /etc/X11/xorg.conf
  • and change all /dev/wacom occurences into /dev/input/wacom (created by wacom-tools udev scripts), then save the file.
  • You should be ready to go after you have restarted X. Remember to configure the "Extended input devices" in your graphic applications (Gimp, Inkscape), however you can already check if it's working by moving your stylus on the tablet : the mouse cursor should go through the whole screen.

How to enable Multicore Support

sudo gedit /etc/X11/xorg.conf
  • Add the following line to the appropriate "Monitor" section 
Modeline	"1920x1200" 154 1920 1968 2000 2080 1200 1203 1209 1235
  • For example the HP2335 should now look like: 
Section "Monitor"
	Identifier	"hp L2335"
	Option		"DPMS"
	Modeline	"1920x1200" 154 1920 1968 2000 2080 1200 1203 1209 1235

How to Configure Ubuntu/Kubuntu with WPA using Network-Manager

Ubuntu Dapper in typical cases can configure WPA to work out of the box with minimal hassle. You'll need to install network-manager.


For Ubuntu: 

sudo apt-get install network-manager-gnome

For Kubuntu (will install knetworkmanager): 

sudo apt-get install network-manager-kde

Logout/Reboot.

Ubuntu users should now see the NetworkManager Applet in the Gnome notification area. Kubuntu users will probably have to run knetworkmanager before they see NetworkManager in the systray.

If instead, you get a "The NetworkManager applet could not find some required resources. It cannot continue." message, then: 

sudo gtk-update-icon-cache -f /usr/share/icons/hicolor

Once Network-Manager is installed, click on the NM icon in the notification area (default is at the top right of Ubuntu/Gnome). Choose your network, then enter your passphrase. Type a password for the keyring, and you're set.

If you don't see your network, click "Create New Wireless Network...", type your essid/networkname, then choose "WPA Personal" for wireless security.

  • Note: If you installed Kubuntu then installed ubuntu-desktop & network-manager-gnome, you may not be able to use network-manager in Gnome, if at all. In this case, you may have to use WPA Supplicant and do some manual editing of conf files to get WPA up and running.
  • Note: When you first log into Gnome/KDE, the keyring application will ask for a password. Future revisions of Network-Manager should resolve this.

Remote Access

Remote Login via XDMCP

What is XDMCP?

GNOME windows can support several different users simultaniously. Unlike vncviewer that just duplicates the current screen on a remote system, XDMCP allows several different users to login and run different GNOME sessions at the same time. So if you have a fast computer runing Ubuntu, several users can use their slow machines to login and run heavy applications only available on the fast machine.

How to turn on the XDMCP feature

To turn on the XDMCP feature on the fast computer, click the menu 

System -> Administration -> Login Window

In the Login Window Preferences dialog window, select 

Remote Tab -> Style: Same as Local ->  Close the dialog window -> Restart the PC
How to login from another PC running Ubuntu 
1. Reboot the slow PC and stop at the login screen
2. Click Options at the lower left corner of the login screen
3. Select "Remote Login via XDMCP"
4. On the dialog window, type in the host name or ip of the fast computer you want to login to

sudo mount /dev/hda1 /media/windows/ -t ntfs -o nls=utf8,umask=0222
  • To unmount Windows partition 
sudo umount /media/windows/

How to mount/unmount Windows partitions (FAT) manually, and allow all users to read/write

e.g. Assumed that /dev/hda1 is the location of Windows partition (FAT)
Local mount folder: /media/windows
  • To mount Windows partition 
sudo mkdir /media/windows
sudo mount /dev/hda1 /media/windows/ -t vfat -o iocharset=utf8,umask=000
  • To unmount Windows partition 
sudo umount /media/windows/

How to mount Windows partitions (NTFS) on boot-up, and allow users read and write access

Warning: Ntfs writing support is still experimental. You should not enable it on production machines and/or volumes you don't have backups of. Proceed at your own risk! 

sudo apt-get install libfuse2 fuse-utils
  • Download the latest ntfsprogs package (these are from the Dapper repositories, so they are safe to install.)

libntfs8 ntfsprogs libfuse2 fuse-utils

  • Install the downloaded packages 
sudo dpkg -i libfuse2_*.deb fuse-utils_*.deb ntfsprogs_*.deb libntfs8_*.deb
  • Add fuse to the list of modules to load 
echo fuse | sudo tee -a /etc/modules
  • Create a user group to access the ntfs disks 
sudo addgroup ntfs
  • The output should look something like this, remember the GID (the number printed after the group name) as it may differ and we will need it later:
Adding group `ntfs' (1002)...
Done.
  • Create the local mount folder and edit the fstab file to mount the disks to this folder.
e.g. Assumed that /dev/hda1 is the location of Windows partition (NTFS)
Local mount folder: /media/windows 
sudo mkdir /media/windows
sudo cp /etc/fstab /etc/fstab.bak
gksudo gedit /etc/fstab
  • Append the following line at the end of file, using the GID number previously. The umask following this GID allows write access just to owner (root) and group (ntfs), and read access to everyone. 
/dev/hda1    /media/windows    ntfs-fuse    auto,gid=1002,umask=0002    0    0
  • Save the edited file.
  • Add users to the ntfs group, where "username" is the name of the user you would like to have write access 
sudo adduser username ntfs

sudo rm /sbin/mount.ntfs-fuse && sudo ln /usr/bin/ntfsmount /sbin/mount.ntfs-fuse
  • If you reboot now, the disk will be writable to the selected users when they logon. If you want the changes to take effect immediately without rebooting, execute the following command, ignoring the errors about "/" and others not being unmounted. You'll have to logout from all your user sessions for the new group to be acknowledged (usually a logout from your graphical session and login back again will do it). 
sudo modprobe fuse && sudo umount -a && sudo mount -a

Security

What are the basic things I need to know about securing my Ubuntu

  • Read #General Notes
  • Ensure hard drive is first in BIOS boot-up sequence
    • To prevent trespassers from using Linux Installation CD which allows them to gain root user access
    • To prevent trespassers from using Linux Live CD (e.g. UBUNTU/KNOPPIX/MEPIS) which allows them to destroy/browse/share the entire hard drive
    • To prevent trespassers from installing another Operating System
  • Ensure a password is set for BIOS
    • To prevent trespassers from changing the BIOS boot-up sequence
  • Ensure computer is located at a secured place
    • To prevent trespassers from removing computer's hard drive which allows them to destroy/browse/share the entire hard drive from a different computer
    • To prevent trespassers from removing computer's on-board battery which resets the BIOS password
  • Ensure passwords used on the system cannot be easily guessed
    • To prevent trespassers from cracking password file using brute force attacks (e.g. John the Ripper)
    • Create password with minimum length of 8 characters
    • Create password with mixture of characters/numbers, and upper/lower case
    • Not create a password with just a single or just a typical union of main languages (english, german, french, spanish...) dictionary words
  • Ensure interactive editing control for GRUB menu is disabled
  • Ensure history listing is disabled in Console mode
  • Ensure Ctrl+Alt+Del is disabled in Console mode
  • Ensure interactive option is set for remove, copy and move of files/folders in Console mode
  • For day to day usage, login as a normal user
  • Disable root user account, use "sudo" instead
    • To reduce the amount of time spent with root privileges, and thus the risk of inadvertently executing a command as root
    • "sudo" provides a more useful audit trail (/var/log/auth.log)
    • Read #How to disable root user account
  • Install a Firewall
  • Perform vulnerability test

How to disable all interactive editing control for GRUB menu

  • Run This: 
grub-md5-crypt 

Password: 
Retype password: 
$1$tumnZ1$xB/shuXs7MlawZXkLiBDV/
  • Backup your current configuration file 
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst_backup
gksudo gedit /boot/grub/menu.lst
  • Find this section 
...
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
#   password --md5 $1$tumnZ1$xB/shuXs7MlawZXkLiBDV/
# password topsecret
...
  • Add the following line below it 
password --md5 $1$tumnZ1$xB/shuXs7MlawZXkLiBDV/ (encrypted password above)
  • Find the section(s) that look like this (note the 'recovery mode' and the word 'single'): 
...
title		Ubuntu, kernel 2.6.10-5-386 (recovery mode)
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.10-5-386 root=/dev/hda2 ro single
initrd		/boot/initrd.img-2.6.10-5-386
savedefault
boot
...
  • Add lock between the title and root lines: 
...
title		Ubuntu, kernel 2.6.10-5-386 (recovery mode)
lock
root		(hd0,1)
...
  • Save the edited file

This will make it so your grub console will require a password to edit the lines, and the recovery modes won't work unless the password is typed. To access the other grub options at the menu, follow the instructions at the bottom of the screen. It will be something like pressing p and typing your password.

How to disable history listing in Console mode 

rm -f .bash_history
gedit ~/.bash_profile
  • Add the following: 
export HISTFILESIZE=4
unset HISTFILE=5

# Change this to a reasonable number of lines to save, I like to save only 100.
export HISTSIZE=1

# Ignores duplicate lines next to each other
export HISTCONTROL=ignoredups

This will disable Bash history for the user, retaining keystroke history and recall to use while limiting recall history to 100 lines. This will also not record duplicate lines next to each other.

How to disable Ctrl+Alt+Del from restarting computer in Console mode 

sudo cp /etc/inittab /etc/inittab_backup
gksudo gedit /etc/inittab
  • Find this line 
...
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
...
  • Replace with the following line 
#ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
  • Save the edited file 
sudo telinit q

How to enable prompt before removal/overwritten of files/folders in Console mode

How to setup a LoJack system for your laptop


What: Quote from Wikipedia: "LoJack is an aftermarket vehicle tracking system that allows cars to be tracked by police after being stolen. The manufacturer claims a 90% recovery rate. The name "LoJack" is a play on the word "hijack," meaning the theft of a vehicle through force."

Why: If your laptop is ever stolen and connected to the Internet. You will be able to find out from what IP it connects to the Internet from and contact the authorities.

How:

  • Get a free dynamic IP account from one of the many providers. Here we will use DynDNS. 
sudo apt-get install ddclient
  • Edit the configuration file /etc/ddclient.conf using you fevorite text editor (emacs, gedit, kedit or even vi) 
sudo emacs /etc/ddclient.conf
  • Make it look like this: 
# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
pid=/var/run/ddclient.pid
protocol=dyndns2
use=web
server=members.dyndns.org
login=YourNameHere
password='YourPasswordHere'
YourHostNameHere.gotmyip.com
NOTE:
* Make sure that you use the web IP detection method.
* Specify your own user id instead of the place holder YourNameHere.
* Specify your own password instead of the place holder YourPasswordHere, make sure to surround it with single quotes.
* The last line should specify the hostname you registered with the dynamic IP service.
  • You can now start the ddclient daemon, or wait until your next reboot. 
sudo /etc/init.d/ddclient start
  • The hostname you registered with your dynamic IP service should be updated. You can test it with the ping command: 
ping YourHostNameHere.gotmyip.com
Even if your laptop has a firewall that prevents pings the hostname should resolve to the IP of the network gateway that your laptop is connected to.
Now all that is left is for someone to steal your laptop.....

How to identify the name of the boot drive (hd0, hd1, hd2, etc)

Press "c" on boot menu. If you don't see a boot menu, press ESC key first when booting to show the boot menu.

Type: 

root (hd0,0)

Most likely you will get "(hd0,0) ext2fs", which should be your current Linux drive. Now change hd0 to hd1 to see what is there. 

root (hd1,0)

If you get "(hd1,0) filesystem type unknown, partition type 0x7", then hd1 is a Windows drive.

Now change hd1 to hd2, keep going until you reach hd7.

How to compile .deb files from source

  • Read #General Notes
  • Read #How to add extra repositories
  • There are various programs available to help automate the process of create .deb files from source. For more information, see the links at the end of this section. A basic well tested method is described here.
  • Install the necessary software to build the source (build-essential may be all that is necessary, though there may be other dependencies) and checkinstall (which creates deb files). 
sudo apt-get install checkinstall build-essential
  • In the directory where you have extracted the source, after you have run ./configure and make you can create a .deb file and install it with either of the following commands. The second -D option creates a .deb file in the directory that you can share with others or install without needing the source. 
sudo checkinstall

How to type extended characters

  • Add the keyboard layout US English International (with dead keys)
  • Make US English International (with dead keys) the default keyboard layout.

The key marked ['"] is now a dead key. When you press it, nothing happens. However if you press a consonant immediately afterwards, the consonant appears with an accent.

  • ' + a = á
  • ' + e = é
  • and so on for i-í, o-ó, y-ý, c-ć, z-ź, n-ń, l-ĺ, u-ú, r-ŕ
  • " + a = ä
  • " + e = ë
  • and so on for y-ÿ, u-ü, i-ï, o-ö

Similarly, ` and a consonant generates à, è, ù, ì, ò. Similarly, ~ and a consonant generates ã, ũ, ĩ, õ, ñ.

To type ' and ", press RightAlt+' and RightAlt+" respectively. To type ' and ", you may also press '+<space> and "+<space> respectively.

There are more characters available by keeping RightAlt pressed and typing a character. Therefore,

  • RightAlt+q = ä
  • RightAlt+w = å
  • RightAlt+e = é
  • RightAlt+r = ®
  • RightAlt+t = þ
  • RightAlt+y = ü
  • RightAlt+u = ú
  • RightAlt+i = í
  • RightAlt+o = ó
  • RightAlt+p = ö
  • RightAlt+[ and ] for « and » respectively.
  • RightAlt+a = á
  • RightAlt+s = ß
  • RightAlt+d = ð
  • RightAlt+l = ø
  • RightAlt+; = ¶
  • RightAlt+: = °
  • RightAlt+z = æ
  • RightAlt+c = ©
  • RightAlt+n = ñ
  • RightAlt+m = µ
  • RightAlt+, = ç
  • RightAlt+/ = ¿
  • RightAlt+1 = ¡
  • RightAlt+2 = ²
  • RightAlt+3 = ³
  • RightAlt+4 = ¤
  • RightAlt+5 = €
  • RightAlt+6 = ¼
  • RightAlt+7 = ½
  • RightAlt+8 = ¾
  • RightAlt+9 = ‘
  • RightAlt+0 = ’
  • RightAlt+- = ¥
  • RightAlt+= = ×
  • RightAlt+! = ¹
  • RightAlt+@, then o = ő (and Ő).
  • RightAlt+#, then a = ā (and Ā). Similarly for ēĒ, ūŪ, īĪ, ōŌ.
  • RightAlt+$ = £
  • RightAlt+% =
  • RightAlt+^ =
  • RightAlt+& =
  • RightAlt+*, then a = ą (and Ą). Similarly for ęĘ, įĮ.
  • RightAlt+(, then a = ă (and Ă)
  • RightAlt+(, then g = ğ (and Ğ)
  • RightAlt+), then a = å (and Å)
  • RightAlt+_ =
  • RightAlt++ = ÷

How to set the Compose key to type special characters

  • Click System, Preferences, Keyboard.
  • Under Layout Options, expand on Compose key position.

Now you can type extended characters using the RightWin key (next to AltGr), according to this keyboard settings file. Specifically, the lines that start with GDK_Multi_key are those that we can use here. The Compose key is actually GDK_Multi_key.

Some examples,

  • RightWin + C + = produces €
  • RightWin + = + C produces €
  • RightWin + C + O produces ©
  • RightWin + O + C produces ©
  • RightWin + a + ' produces á
  • RightWin + a + " produces ä
  • RightWin + a + ` produces à
  • RightWin + a + ~ produces ã
  • RightWin + a + * produces å
  • RightWin + a + ^ produces â
  • RightWin + a + > produces â
  • RightWin + a + , produces ą
  • RightWin + e + - produces ē
  • RightWin + S + 1 produces ¹
  • RightWin + S + 2 produces ²
  • RightWin + S + 3 produces ³

How to limit the user accounts that can connect through ssh remotely

e.g. If you enable the SSH server, then any user with a valid account can connect remotely
This can lead to security risks, as there exist remote password cracking tools that
try common username/password pairs.
  • Keep a backup of the ssh server configuration file with

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.ORIGINAL

  • Edit the configuration file

gksudo gedit /etc/ssh/sshd_config

  • Change the parameter PermitRootLogin from yes to no. The superuser must not be able to connect directly from remote.
  • Add the parameter AllowUsers and specify the usernames (space separated) that can connect remotely.
  • You can also use DenyUsers for fine-grained selection of users.
  • If you enable the openssh server and you have no intention for now to enable remote connections, you may add AllowUsers nosuchuserhere to disable anyone connecting.

Database Server

How to install MYSQL Database Server 

sudo apt-get install mysql-server
  • MySQL initially only allows connections from the localhost (127.0.0.1). We'll need to remove that restriction if you wish to make it accessible to everyone on the internet. Open the file /etc/mysql/my.cnf 
gksudo gedit /etc/mysql/my.cnf
  • Find the line bind-address = 127.0.0.1 and comment it out 
...
#bind-address           = 127.0.0.1
...
  • MySQL comes with no root password as default. This is a huge security risk. You'll need to set one. So that the local computer gets root access as well, you'll need to set a password for that too. The local-machine-name is the name of the computer you're working on. For more information see here 
mysqladmin -u root password your-new-password
mysqladmin -h root@local-machine-name -u root -p password your-new-password
sudo /etc/init.d/mysql restart

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
  • If you don't have a CD available make SURE you comment/remove the line pertaining to your CD media 
gksudo gedit /etc/apt/sources.list
  • To upgrade from Dapper to Edgy, just replace (ctrl+h) all instances of 'dapper' with 'edgy' within the /etc/apt/sources.list. (See how to add extra repositories).
  • Validate updates and upgrade. 
sudo aptitude update 
sudo aptitude dist-upgrade

(Note the use of aptitude rather than apt-get. Please use aptitude as it handles dependencies better and is more likely to succeed in upgrading your system.)

  • Save your session, reboot, and enjoy.


NOTE: Try to upgrade from immediately previous versions, e.g. Dapper to Edgy not Breezy to Edgy. If you are running Hoary for instance, upgrade Hoary->Breezy->Dapper->Edgy.
