linux - 树莓派 : Unable to set my RPI as a router

Question

我有一个 RPI，它通过有线连接到我们组织的路由器，并且在其 USB 端口中插入了一个 WIFI 加密狗。

首先我遵循了这个指令集:

http://sirlagz.net/2012/08/09/how-to-use-the-raspberry-pi-as-a-wireless-access-pointrouter-part-1/

下面是我的配置:

/etc/网络/接口(interface)

auto lo
iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet static
    wireless-essid Test
    wireless-key ABCDEFGHIJ
    wireless-channel 11
    wireless-mode managed
    address 192.xxx.x.2
    network 192.xxx.1.0
    netmask 255.255.255.0
    route add default gw 198.xxx.1.1

以下是系统日志:

Dec 13 09:46:07 raspberrypi hostapd: wlan0: STA b8:b4:2e:76:ad:1b IEEE 802.11: authenticated
Dec 13 09:46:07 raspberrypi hostapd: wlan0: STA b8:b4:2e:76:ad:1b IEEE 802.11: associated (aid 1)
Dec 13 09:46:07 raspberrypi hostapd: wlan0: STA b8:b4:2e:76:ad:1b RADIUS: starting accounting session 52AAD693-00000003
Dec 13 09:46:07 raspberrypi dnsmasq-dhcp[2114]: DHCPDISCOVER(wlan0) b8:b4:xx:xx:xx:xx
Dec 13 09:46:07 raspberrypi dnsmasq-dhcp[2114]: DHCPOFFER(wlan0) 192.xx.1.57 

下面是我的 hostapd 配置:

interface=wlan0
driver=nl80211
ctrl_interface=/var/run/hostapd
ssid=TEST
wpa_passphrase=TESTTESTTEST
hw_mode=g
channel=11
wmm_enabled=0

以下是 DHCP 配置:

option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;

send host-name = rasberrypi;
subnet 192.xxx.1.0 netmask 255.255.255.0 {
    range 192.xxx.1.3 192.xxx.1.240;
    option subnet-mask 255.255.255.0;
    option routers 192.xxx.1.2;
    option domain-name "test.in";
    default-lease-time 21600;
    max-lease-time 43200;
};

问题是，在我的 WIFI 移动设备上为我的 WIFI essid 选择并输入密码后，我一直收到“获取 IP 地址..”并且根本没有连接。我尝试使用其他设备但输出相同。

我的配置和设置是否正常？

# iwconfig
mon.wlan0  IEEE 802.11bgn  Mode:Monitor  Frequency:2.462 GHz  Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

wlan0     IEEE 802.11bgn  Mode:Master  Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

lo        no wireless extensions.

eth0      no wireless extensions.

我还设置了 dnsmasq，下面是我的配置:

root@raspberrypi:~# cat /etc/dnsmasq.conf  | grep -v '#'
interface=wlan0
dhcp-range=192.xxx.1.2,192.xxx.1.254,255.255.255.0,12h

我确实在系统日志中看到以下几行:

Answer 1

你见过吗？

wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
# I've set these to WPA-PSK to indicate that we are using a Pre-Shared Key with CCMP encryption.
# Otherwise, hostapd also has a built in RADIUS server that we can use for authentcation
# But I'll leave that to another post.

在您的 hostapd 配置中至少添加:wpa_key_mgmt=WPA-PSK，否则默认情况下它将使用 RADIUS。正如我们在您的日志中看到的那样。
