新路程------rtl8188的配置

runwpa文件

#!/bin/bash

if [ "`which iwconfig`" = "" ] ; then   如果运行which iwconfig的结果为空则输出下面的提示
echo "WARNING:Wireless tool not exist!"
echo "        Please install it!"
exit
else
if [ `uname -r | cut -d. -f2` -eq 4 ]; then  运行uname -r，以.为分隔符取第二个参数如果等于4则运行if
wpa_supplicant -D ipw -c wpa1.conf -i wlan0
else
if [ `iwconfig -v |awk '{print $4}' | head -n 1` -lt  18 ] ; then
wpa_supplicant -D ipw -c wpa1.conf -i wlan0  
else  
wpa_supplicant -D wext -c wpa1.conf -i wlan0

关于wpa_supplicant 无线配置

options:
  -b = optional bridge interface name
  -B = run daemon in the background
  -c = Configuration file
  -C = ctrl_interface parameter (only used if -c is not)
  -i = interface name
  -d = increase debugging verbosity (-dd even more)
  -D = driver name (can be multiple drivers: nl80211,wext)
  -g = global ctrl_interface
  -K = include keys (passwords, etc.) in debug output
  -t = include timestamp in debug messages
  -h = show this help text
  -L = show license (GPL and BSD)
  -o = override driver parameter for new interfaces
  -O = override ctrl_interface parameter for new interfaces
  -p = driver parameters
  -P = PID file
  -q = decrease debugging verbosity (-qq even less)
  -v = show version
  -W = wait for a control interface monitor before starting
  -N = start describing new interface

wlan0dhcp文件：

#!/bin/bash


var0=`ps aux|awk '/dhclient wlan0/'|awk '$11!="awk"{print $2}'`  列出dhclient wlan0这个进程的第二个参数

#/usr # ps aux|awk '/dhclient wlan0/'|awk '$11!="awk"{print $2}'
#root
#/usr # ps aux|awk '/dhclient wlan0/'
# 1132 root       0:00 awk /dhclient wlan0

kill $var0  从这里看是抓进程号来杀死进程，应该是"awk"{print $1}才对啊

cp ifcfg-wlan0 /etc/sysconfig/network-scripts/

dhclient wlan0  如果是用DHCP获取IP的，那么用dhclient或dhcpcd获取ip

var1=`ifconfig wlan0 |awk '/inet/{print $2}'|awk -F: '{print $2}'`抓带inet的第二个参数以及以：为分隔符的第二个参数

rm -f /etc/sysconfig/network-scripts/ifcfg-wlan0

echo "get ip: $var1"
