radius认证服务器ip该怎么填_radius认证服务器拒绝原因

大家好,又见面了,我是你们的朋友全栈君。 1. AAA和Radius概述   AAA是验证授权和记账Authentication,Authorization,and Accounting 的简称。它是运行于NAS上的客户端程序,它提供了一个用来对验证、授权和记账这三种安全功能进行配置的一致的框架。AAA的配置实际上是对网络安全的一种管理,这里的网络安全主要指访问控制,包括哪些用户可以访问网络服务器,具有访问权的用户可以得到哪些服务,如何对正在使用网络资源的用户进行记账。下面简单介绍一下验证, 授权,记账的作用。   · 验证(Authentication): 验证用户是否可以获得访问权可以选择使用RADIUS协议   · 授权(Authorization) : 授权用户可以使用哪些服务   · 记账(Accounting) : 记录用户使用网络资源的情况   · AAA的实现可采用RADIUS 协议RADIUS 是Remote Authentication Dial In User Service 的简称原来的初衷是用来管理使用串口和调制解调器的大量分散用户。现在已经远不止这些应用了

hostapd 配置「建议收藏」

hostapd is an IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator. This page is dedicated to the Linux documentation of it’s implementation and use. Please refer to the hostapd home page for information for other Operating Systems. As far a Linux is concerned, out of the old drivers you can only use these 3 drivers with hostapd: HostAP madwifi prism54 All new mac80211 based drivers that implement AP functionality are supported with hostapd’s nl80211 driver. The mac80211 subsystem moves all aspects of master mode into user space. It depends on hostapd to handle authenticating clients, setting encryption keys, establishing key rotation policy, and other aspects of the wireless infrastructure. Due to this, the old method of issuing ‘ iwconfig <wireless interface> mode master’ no longer works. Userspace programs like hostapd now use netlink (the nl80211 driver) to create a master mode interface for your traffic and a monitor mode interface for receiving and transmitting management frames. Getting hostapd Using your distributions hostapd It is advisable to try your distributions version of hostapd before taking the time to compile and install your own copy. This will make future maintenance easier as you’ll be able to use the init scripts shipped by the distro and hostapd will be updated by it as well. If your distribution ships 0.6.8 or later, you can test with this bare minimum config by creating the file hostapd-minimal.conf: #change wlan0 to your wireless device interface=wlan0 driver=nl80211 ssid=test channel=1 If that config errors out with something like: hostapd $ sudo hostapd ./hostapd-minimal.conf Configuration file: ./hostapd-minimal.conf Line 2: invalid/unknown driver ‘nl80211’ 1 errors found in configuration file ‘./hostapd-minimal.conf’ that means that your distro is not shipping hostapd with nl80211 driver support and you’ll need to follow the building instructions that follow. If it works, you can skip down to the configuring hostapd secti
