Uoffisiell Ubuntu 6.06 (Dapper Drake) Linux Nybegynnerguide

Denne guiden ble startet av Chua Wen Kiat fra Kuala Lumpur, Malaysia. Den blir for tiden vedlikeholdt og oppdatert av Linux Senteret ved Universitetet i Latvia og alle andre som er villig til å bidra. Den norske oversettelsen er gjort av Håvar Nielsen og utgitt under samme GPL lisens som det opprinnelige arbeidet. Har du kommentarer, send meg en epost.

Denne guiden kan diskuteres i det offisielle UbuntuGuide.org forumet på ubuntuforums.org. Kom innom og bli med i diskusjonen.


Uheldigvis kan kun registrerte brukere redigere denne wiki'en på grunn av wiki-vandalisme. Kun registrerte brukere kan lage en brukerkonto for deg. Dersom du ønsker å bli med og hjelpe til, la meg vite det [ raivis.dejus _at_ linux.edu.lv ]. (Bruk engelsk i eposten). Ikke glem å si hvilket brukernavn du ønsker deg eller hvorfor du vil ha en brukerkonto, (hva du ønsker å forandre eller legge til guiden).

Denne guiden holder på å bli oversatt til norsk. Arbeidet er ennå ikke fullført, og omtrent halvparten av denne siden er fortsatt på engelsk. Ønsker du å hjelpe til med oversettingen, så må du gjerne gjøre det. Denne siden er på bokmål og ikke nynorsk. Dersom du vil lage en nynorsk oversetting, så må du gjerne opprette en egen side for det.

Generelle merknader

  1. Dette er en uoffisiell Ubuntu 6.06 (Dapper Drake) nybegynnerguide og har ingenting med Ubuntu eller Canonical Ltd å gjøre.
  2. Denne guiden kan diskuteres i det offisielle (http://www.ubuntuforums.org/forumdisplay.php?f=78 UbuntuGuide.org-forumet] på ubuntuforums.org. Kom innom å bli med å diskuter.
  3. Denne guiden er testet på en full installsjon av Ubuntu 6.06 x86 Innstall CD (Dapper Drake).
  4. Hvis du ser en blåaktig boks, betyr det at du må kjøre kommandoene i en terminal (Programmer -> System -> Terminal) eller bruke innholdet i boksen som nevnt i andre instruksjoner på denne siden.
  5. For å redusere skrivefeil, kopier og lim inn kommandoene i en terminal (høyreklikk og klikk på "kopier" eller "lim inn". Du kan også bruke Ctrl+C for å kopiere og Shift+Insert for å lime inn, eller bare marker for å kopiere og klikk på den midterste museknappen for å lime inn).
  6. sudo eller gksudo betyr superuser do. sudo vil be deg om å skrive inn passordet ditt. Vennligst skriv inn ditt passord.
  7. Hvis du ønsker mer informasjon om en kommando, bare slå den opp i manualsidene gjennom kommandoen: man kommando. man sudo vil for eksempel vise manualsiden for sudokommandoen.
  8. Hvis du er lei av å skrive apt-get hele tiden, les #How to apt-get the easy way (Synaptic).
  9. apt-get og wget krever en Internettilkobling for å installere/oppdatere/laste ned programmer.
  10. For å laste ned en fil, høyreklikk på linken -> Velg "Lagre link som..." -> Sørg for at filnavnet og filtypen er riktig
  11. Hvis du øsnker å hjelpe til med å oversette Ubuntu til ditt morsmål eller hjelpe Ubuntu på andre måter, besøk: https://launchpad.net/
  12. Må ubuntuånden være med deg alltid...


Hvis du bruker Kubuntu, behøver du ikke å installere gedit lengre, fordi det er en symbolsk link fra gedit til kate, så du kan bruke alle kommandoene under uten problemer. Ellers, dersom du ønsker å bruke gedit som ditt tekstredigeringsverktøy allikevel, kjør følgende kommando i en terminal:
sudo apt-get install gedit
Hvis "gedit" kommandoen eller (den sombolske linken) ikke virker, kan du også lage den:
sudo ln -s /usr/bin/kate /usr/bin/gedit
Hvis du bruker en 64-bit versjon, bytt ut alle "i386" med "amd64"

gksudo gedit /etc/apt/sources.list
  • Bytt ut alt med følgende linjer
Denne listen er forandret iforhold til den engelske listen, ved at den bruker norske servere. Dette kan du se ved at det står "no." forran archive.ubuntu.com (no = landskoden for Norge)
## Legg til kommentarmarkører (##) forran hvilken som helst linje for at den ikke skal bli brukt. 
## Bruk den følgende sources.list på eget ansvar.

deb http://no.archive.ubuntu.com/ubuntu dapper main restricted universe multiverse
deb-src http://no.archive.ubuntu.com/ubuntu dapper main restricted universe multiverse

## STORE FEILFIKS OPPDATERINGER laget etter den opprinnelige utgivelsen

Hvordan installerer jeg Windows programmer i Linux (Wine)?

Det fulle navnet itl Wine er "Wine Is Not an Emulator." Wine er en åpen kildekode implementasjon av Windows API'en over X og Unix. Tenk på Wine som et kompatibilitetslag for å kjøre Windows programmer. Wine krever ikke Microsoft Windows, siden det er en helt fri alternativ implementasjon av Windows API'en, bestående av 100% ikke-Microsoft kode. Wine kan allikevel konfigureres til å bruke orginale Windows DLL'er, hvis de er tilgjengelige.

Med andre ord, Wine vil la deg kjøre Windows programmer under Linux.

  • Først, legg til et reservoar for Wine:
gksudo gedit /etc/apt/sources.list

# 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

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

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

If you can control fan speeds, great. Now creat a file called /etc/init.d/fancontrol, and paste in the following

#!/bin/sh
#
# Fancontrol start script.
#

set -e

# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol-pid

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

  • You need lm-sensors to display CPU temps, fan speed, and voltages in GKrellM.
  • You need nvidia driver to display nvidia GPU temperatures.
  • You need hddtemp to display harddrive temperatures

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 hddtemp

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.
lsmod | grep acx
  • If you have acx module loaded, remove it. It could also be acx_pci or similar.
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 manager1, 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.

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.

Security

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

  • Read #Generelle merknader
  • 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.

  • 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.

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.
  • Choose Right-Win key is compose, click Close.

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

...
#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

Upgrading Ubuntu

How to upgrade from Hoary Hedgehog -> Breezy Badger -> Dapper Drake

  • First, make sure you're fully upgraded:
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

/etc/apt/sources.list

for an upgrade to breezy your sources.list should look something similar to this:

## Uncomment the following two lines to fetch updated software from the network
deb http://us.archive.ubuntu.com/ubuntu breezy main restricted
deb-src http://us.archive.ubuntu.com/ubuntu breezy main restricted

## Uncomment the following two lines to fetch major bug fix updates produced
## after the final release of the distribution.
deb http://us.archive.ubuntu.com/ubuntu breezy-updates main restricted
deb-src http://us.archive.ubuntu.com/ubuntu breezy-updates main restricted

## Uncomment the following two lines to add software from the 'universe'
## repository.
## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu
## team, and may not be under a free licence. Please satisfy yourself as to
## your rights to use the software. Also, please note that software in

  • To upgrade from breezy to dapper, just replace (ctrl+h) all instances of 'breezy' with 'dapper' within the /etc/apt/sources.list
  • Save this file.
sudo apt-get update
