Neoficialus Ubuntu 6.06 (Dapper Drake) naujoko gidas

Šį pradžiamokslį pradėjo kurti Chua Wen Kiat (Kuala Lumpur, Malaizija). Dabar jis išlaikomas Latvijos Universiteto Linux centro ir kiekvieno norinčio padėti.


Pagalbininkai: Orvils, Quash, Jiyuu0, Cargo, Byte, cope, krampo, Simos, Stubby, eljaco, shai, ThunderM, Hasile, adammichaelroach, Belisarivs, Cheator, Hank, Kaotiks, richux, Mantas Smelevičius...


Diskutuoti apie šį gidą galima oficialiame UbuntuGuide.org Forume esančiame ubuntuforums.org. Užeikite ir prisijunkite prie diskusijų.

Deja, dėl wiki-vandalizmo tik registruoti vartotojai gali redaguoti šį wiki, ir tik registruoti vartotojai gali sukurti tau naują vartotoją. Jei nori prisijungti prie mūsų ir padėti vystytis šiam projektui, pranešk [ orvils _at_ gmail _dot_ com ]. Nepamiršk parašyti kokio vartotojo vardo norėtum ir kodėl tau jo reikia (ką norėtum pakeisti ar pridėti į šį pradžiamokslį).

Bendrosios pastabos

  1. Tai yra neoficialus Ubuntu 6.06 (Dapper Drake) naujoko gidas. Jis nesusijęs su Ubuntu ar Canonical Ltd.
  2. Diskutuoti apie šį gidą galima oficialiame UbuntuGuide.org forume esančiame ubuntuforums.org. Užeikite ir prisijunkite prie diskusijų.
  3. Šis gidas testuotas pilnai instaliavus Ubuntu 6.06 x86 Install CD (Dapper Drake).
  4. Jei matote melsvą laukelį, tai reiškia kad turite įvykdyti nurodytas komandas Terminal'e (Applications -> System Tools -> Terminal) arba pasinaudoti to laukelio turiniu pagal kitus pateiktus nurodimus.
  5. Kad išvengtumėte rašybos klaidų nukopijuokite komandas ir įklijuokite jas tiesai į Terminal'ą (deš. pelės klavišu ant komandų -> "Copy" ar "Paste". Taip pat galite naudoti Ctrl+C kopijavimui ir Shift+Insert įklijavimui, arba tiesiog pažymėkite kopijavimui ir vid. peles klavišu įklijavimui).
  6. sudo ar gksudo reiškia superuser do (veiksmus atlieka supervartotojas). Komanda sudo paprašys jūsų slaptažodžio - "Password:". Įveskite savo vartotojo slaptažodį.
  7. Jei norite daugiau informacijos apie kokią nors komandą, paprasčiausiai pažiūrėkite vadove (manual'e), naudodamiesi komanda man. Pavyzdžiui, komanda man sudo parodys informaciją apie komandą sudo.
  8. Jei pavargote kiekvieną kartą įvedinėti komandą apt-get, skaitykite #How to apt-get the easy way (Synaptic).
  9. Komandoms apt-get ir wget reikalingas interneto ryšys, kad būtų galima įrašyti/atnaujinti/parsisiųsti programas.
  10. Failų parsisiuntimui spustelėkite deš. pelės klavišu ant nuorodos -> Pasirinkite "Save Link As..." -> Įsitikinkite, kad bylos pavadinimas ir plėtinys yra teisingi.
  11. Jei norite padėti išversti Ubuntu į savo gimtąją kalbą ar kitaip pagelbėti Ubuntu - aplankykite https://launchpad.net/
  12. Tegul "žmogiškumo kitiems" dvasia visada būna su jumis...


Jei naudojate Kubuntu jums nereikia instaliuoti gedit, nes dabar jau yra simbolinė nuoroda iš gedit į kate, taigi be problemų galite naudoti visas čia esančias komandas. Tiesa, jei norite naudoti gedit kaip savo redaktorių, darykite:
sudo apt-get install gedit
Jei "gedit" komanda (simbolinė nuoroda) neveikia, galite sukurti ją:
sudo ln -s /usr/bin/kate /usr/bin/gedit
Jei naudojate 64 bitų versiją pakeiskite visus "i386" į "amd64"

  • Pastaba: Prieš diegimą atkreipkite dėmesį, kad tam tikri pateikiami kodekai kai kuriose šalyse gali būti uždrausti. Jūs esate atsakingas už tai kad būtų laikomasi šių įstatymų.
  • naudokite savo mėgstamą teksto redaktorių (kwrite, gedit)
gksudo kwrite /etc/apt/sources.list
  • Atkomentuokite šias eilutes
#deb http://archive.ubuntu.com/ubuntu dapper main
#deb-src http://archive.ubuntu.com/ubuntu dapper main
  • Jei naudojate Ubuntu ar Xubuntu Dapper, failo gale pridėkite šią eilutę.

  • Failo gale pridėkite šią eilutę
@reboot gnome-clipboard-daemon
  • Išsaugokite pakeitimus

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

sudo apt-get install sun-java5-jre sun-java5-plugin
  • Kai paprašis, sutykite su DLJ licencijos sąlygomis.
  • Nustatykite J2SE kaip numatytąją JVM (tai būtina programoms tokioms kaip Frostwire, RSSOwl taip pat ir Mozilla Firefox įskiepiui):
sudo update-alternatives --config java

Pasirinkite nustatymą atitinkantį J2SE.

Kaip įdiegti JRE v5.0 Update 8

  • Nukopijuokite jį į /usr/java/
sudo chmod a+x jre-1_5_0_08-linux-i586.bin
sudo ./jre-1_5_0_08-linux-i586.bin
cd /usr/lib/firefox/plugins
ln -s /usr/java/jre1.5.0_08/plugin/i386/ns7/libjavaplugin_oji.so

  • Perkraukite Mozilla Firefox

Kaip įdiegti Flash grotuvo (Macromedia Flash) įskiepį skirtą Mozilla Firefox

sudo apt-get install flashplugin-nonfree
sudo update-flashplugin
  • Perkraukite Mozilla Firefox

Pastaba: jei Flash grotuve nėra garso (pavyzdžiui YouTube tinklapyje):

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

Pakeiskite:

FIREFOX_DSP=""

Į:

FIREFOX_DSP="aoss"
  • Perkraukite Mozilla Firefox. Dabar garsas turėtų veikti.

Kaip įdiegti PDF Reader (Adobe Reader) su įskiepiu skirtu Mozilla Firefox

sudo apt-get install acroread mozilla-acroread acroread-plugins

Pastaba: Adobe Reader 7.0 neveiks jei veikia SCIM. Pas jus veikia SCIM, jei įdiegėte kitą kalbą į Ubuntu per System -> Administration -> Language Support. Kad to išvengtumėte, darykite tai

gksudo gedit /usr/bin/acroread

Pakeiskite:

#!/bin/sh
#

į:

#!/bin/sh
#
GTK_IM_MODULE=xim

Išsaugokite pakeitimus. Dabar jau Adobe Reader 7.0 turėtų veikti.

Kaip susieti Adobe Reader su PDF failais tarp Nautilus

How to install Internet Explorer + Flash 9

This will install a wine'd version of Internet Explorer 6 with Flash 9, as well as IE 5.5/5.01 if you really want them.

  • Note: Flash 9 will NOT be available in browsers other than IE.
  • Open a terminal and run this:
wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-2.0.tar.gz -O - | tar xvzf -
  • Or, if that doesn't work, use this command:
wget http://modzer0.cs.uaf.edu/~hardwarehank/files/ies4linux-2.0.tar.gz -O - | tar xvzf -
  • Then, just run it:
cd ies4linux-2.0
sh ies4linux

You don't have to run it as root (no sudo). If you do, it will make global symlinks, which is fine if you want that. Otherwise, it will use ~/bin. Read the README:

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

# 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

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"

	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

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

GKrellM is a hardware monitor that can display CPU and GPU temperatures, fan speeds, voltages, CPU load, network load, disk activity, 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..

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, and the installation/configuration is a bit tedious. Later I found "GKrellM", which works much better. 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 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.

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.

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

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

sudo cp /etc/bash.bashrc /etc/bash.bashrc_backup

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 restore GRUB menu after Windows installation

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.

  • 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)

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 password your-new-password
sudo /etc/init.d/mysql restart

How to install MYSQL Administrator

  • 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

  • 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
sudo apt-get upgrade
sudo apt-get dist-upgrade
  • Save your session, reboot, and enjoy.

NOTE:

  • I would NOT suggest upgrading directly from hoary to dapper. Upgrade: hoary->breezy->dapper
