802.1x网络认证
IEEE 802.1x是网络认证主机的标准,通常在大型网络,如校园网络或公司网络中使用,用于无线或有线网络认证。
在配置无线网络时候,需要使用以下工具命令:
wpa_supplicant-wpa_supplicant是支持使用WPA和WPA2(IEEE 802.11i/RSN)协议的的Linux, BSD, Mac OS X,Windows工具命令。iwipping
软件包安装
Linux使用wpa_supplicant软件来实现 802.1x认证。在Ubuntu中,需要安装wpasupplicant
apt install wpasupplicant基本配置
编辑
/etc/wpa_supplicant.conf添加以下内容
# Where is the control interface located? This is the default path:
ctrl_interface=/var/run/wpa_supplicant
# Who can use the WPA frontend? Replace "0" with a group name if you
# want other users besides root to control it.
# There should be no need to chance this value for a basic configuration:
ctrl_interface_group=0
# IEEE 802.1X works with EAPOL version 2, but the version is defaults
# to 1 because of compatibility problems with a number of wireless
# access points. So we explicitly set it to version 2:
eapol_version=2
# When configuring WPA-Supplicant for use on a wired network, we don’t need to
# scan for wireless access points. See the wpa-supplicant documentation if
# you are authenticating through 802.1x on a wireless network:
ap_scan=0无线网络配置
配置
/etc/wpa_supplicant.conf添加
上述配置和在MacBook上安装Gentoo中有关配置802.1x相同,如果使用NetworkManager也可以参考Ubuntu Touch手机设置802.1x无线网络
启动无线:
无线认证通过后,启动dhclient
也可以重新加载 network 脚本
上述手工执行任务成功以后,就可以修改成启动配置:修改
/etc/network/interfaces
有线网络配置
以下案例为有线网络IEEE 802.1x,使用EAP-Tunnelled传输层安全,使用PAP和MD5作为认证协议,不使用证书:
测试网络:
连接Pretected EAP(PEAP)
修改
/etc/network/interfaces
执行以下命令连接
