Allmäna Noteringar


  1. Detta är en Inofficiell Ubuntu 5.10 (Breezy Badger) Nybörjar Guide. Den är inte förknippad med Ubuntu och Canonical Ltd.
  2. Denna guide är testad på en full installation av Ubuntu 5.10 x86 Installations CD (Breezy Badger)
  3. Om du ser en blåtonad box betyder dett att du måste exekvera kommandona i terminal-läge, (Program -> Systemverktyg -> Terminal) eller använda innehållet i boxen som det nämnts i någon annan instruktion.
  4. För att reducera tryckfel, kopiera och klistra in kommandona i terminal-läge (högerklicka på kommandona -> "Kopiera" eller "Klistra in". Du kan också använda Ctrl+C för att kopiera och Shift+Insert för att klistra in)
  5. "sudo" betyder "superuser do". "sudo" kommer att fråga efter "Lösenord:". Vänligen ange användarlösenord
  6. Om du vill ha mer information om något kommando, läs manualsidorna för dessa genom att använda "man" kommandot. Till exempel, "man sudo" kommer att visa manualsidan för "sudo" kommandot.
  7. Om du tröttnar på att skriva "apt-get" hela tiden, Läs #Att apt-get:a det lätta sättet (Synaptic).
  8. "apt-get" och "wget" erfodrar Internet anslutning för att installera/updatera/ladda ner program
  9. För att ladda ner en fil, högerklicka på länken -> välj "Spara länk som..." -> Kontrollera att filnamn och filnamnstillägg är korrekta
  10. Om du vill hjälpa till att översätta Ubuntu till ditt hemspråk eller hjälpa Ubuntu på något annat sätt besök https://launchpad.net/
  11. Må "humanity to others" anden vara med dig...


Om du använder Kubuntu och behöver installera Gedit 
wget http://easylinux.info/uploads/gedit_2.13.1-0ubuntu1_i386.deb
sudo dpkg -i gedit_2.13.1-0ubuntu1_i386.deb
Eller ersätt 'gedit' med 'kwrite', till exempel, instället för att skriva 
 sudo gedit /etc/apt/sources.list
Skriv 
 sudo kwrite /etc/apt/sources.list
Om du använder en 64-bits processor ersätt "i386" med "amd64"

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)

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

sudo 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.
