Unoffizielle Ubuntu 5.10 (Breezy Badger) Anfängerhilfe

Die Ubuntu Hilfe http://ubuntuguide.org/ wurde ursprünglich von Chua Wen Kiat (Kuala Lumpur, Malaysia) gestartet.
Nun wird sie gepflegt und aufrecht erhalten von `Linux Center of University of Latvia' und den Benutzern die bereit sind es weiterzuentwickeln.

Verantwortliche: orvils, Cargo, Quash, Byte, krampo, Simos, Fruchtnektar, ...

Generelles


  1. Dies ist eine unoffizielle Anfänger Hilfe von `Ubuntu 5.10 (Breezy Badger)', und steht in keiner Verbindung mit `Ubuntu and Canonical Ltd.'
  2. Diese Hilfe basiert auf der Voll Installation von `Ubuntu 5.10 x86 Install CD (Breezy Bader)'
  3. Eine Box mit gestrichelten Rand bedeutet das ein Befehl im Terminal Modus ausgeführt werden muss (Anwendungen -> Zubehör -> Terminal)
  4. Um Fehler zu vermeiden, solltet Ihr die Kommandos mit Strg+C kopieren, um sie dann im Terminal mit Shift+Einfg einzufügen.
  5. Der Befehl `sudo' bedeutet, das die nachfolgende Befehle als `Superuser' ausgeführt werden. Sudo erfordert ein Passwort (das eures Users)
  6. Eine ausführliche Hilfe zu jedem Befehl gibt `man [befehl]'. Z.B.: "man sudo" zeigt euch eine Hilfe zu den Befehl `sudo'
  7. Falls Ihr eine einfachere Methode bevorzugt als `apt-get' solltet ihr #How to apt-get the easy way (Synatptic) lesen
  8. `apt-get' und `wget' erfordern eine Internetverbindung zum installieren/updaten/downloaden von Programmen
  9. um eine Datei zu downloaden klickt mit rechtsklick auf den Link und wählt `Link speichern als...'. Versichert euch dass der Dateiname und die Erweiterung richtig ist.
  10. Wenn Ihr helfen wollt, Ubuntu in eure Nationalsprache zu übersetzen, oder Ubuntu auf andere weise helfen wollt, könnt ihr euch mal die Seite: https://launchpad.net/ anschauen!
  11. Falls Ihr irgendwelche Fehler (Bugs) in Ubuntu gefunden habt, oder Fehler so besucht bitte: (link missed | link fehlt) Johannes Matjeschk 01:07, 12 April 2006 (EEST)
  12. Möge die `Humanität zu anderen' immer mit dir sein... ich bin dein Vater, Tux!


Falls Ihr Kubuntu benutzt, solltet ihr noch Gedit nachinstallieren 
wget http://easylinux.info/uploads/gedit_2.13.1-0ubuntu1_i386.deb
sudo dpkg -i gedit_2.13.1-0ubuntu1_i386.deb
Wenn du einen 64-bit Prozessor besitzt, ersetze "i386" mit "amd64"


Oder ersetze `gedit' mit `kwrite', Ein Beispiel:
Was in Gnome so aussieht: 
 sudo gedit /etc/apt/sources.list
würde in Kubuntu so aussehen 
 sudo kwrite /etc/apt/sources.list

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 für 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 für 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 ] für « 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 für ēĒ, ūŪ, īĪ, ōŌ.
  • RightAlt+$ = £
  • RightAlt+% =
  • RightAlt+^ =
  • RightAlt+& =
  • RightAlt+*, then a = ą (and Ą). Similarly für ęĘ, įĮ.
  • RightAlt+(, then a = ă (and Ă)

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 für fine-grained selection of users.
  • If you enable the openssh server and you have no intention für now to enable remote connections, you may add AllowUsers nosuchuserhere to disable anyone connecting.
