Ubuntu Linux Distribution Novice Application guide [i]

The Ubuntu system is a Linux based system, and all of his software updates are installed by command: Apt-get install.

First, the implementation of Chinese input This command is to complete the GCC compiler, the Ubuntu is a variant of Debian, Debian is inclined to use packaged files to execute, and ordinary Linux is compiled based on the source code, through the Gcc,make to complete.

sudo apt-get install build-essential

The command is to make some patches to the compilation environment.

Apt-get BUILD-DEP VIM-GTK

This command is to initialize SCIM Chinese.

sudo apt-get install Scim-pinyin im-switch

Im-switch-z en_us-s Scim-pinyin

So far, the environment has already supported Chinese.

Second, in Ubuntu, the traditional UNIX ' root ' is blocked (that is, you can't log in using root).

Execute the command with root, and precede each command with a ' sudo ' command.

Start a root shell (for example, a window where you can run the root command) using:

Sudo-s

Third, wireless card driver does not get up:

To view the system's wireless device settings:

Iwconfig,

Port Ath0 to automatically obtain IP

Dhclient Ath0

Automatically allow Ath0 to scan available wireless networks

sudo iwlist ath0 scan

Ath0 Scan Completed:

Cell 01-address:00:0c:41:9d:3d:2d

Essid: "Linksys"

Mode:master

frequency:2.437 GHz (Channel 6)

quality=53/94 Signal level=-42 dbm Noise level=-95 dbm

Encryption Key:on

Bit rates:1 mb/s; 2 MB/s; 5 MB/s; 6 MB/s; 9 MB/s

Disable Network

sudo ifdown ath0

Activate network

sudo idup ath0

Set the channel for the wireless network, which should be consistent with the AP

sudo iwconfig ath0 Channel 6

Set Essid

sudo iwconfig ath0 Essid Linksys

Set mode

sudo iwconfig ath0 mode managed

All the interfaces we see with the ifconfig command are not necessarily activated, like Ath0, and I find that even if ath0 is not activated it will appear inside.
