Packetfence 网络准入系统:
开源的准入系统,我公司现在有6-7百人吧,正在用。版本是5.7。现在最新的都出到6.多了
主要用户体验是:用户电脑接入网络,网页任何打开一个网页会自动跳转到一个登陆页面,注册后才可以进入内网。
主要特点:
1.旁路接入
2.支持802.1x或MAB认证
3.完美支持思科2960交换机,可分配VLAN
4.可以查到一个IP地址、MAC地址所在的交换机
5.其它功能可以自己发掘。 发现中国用这个系统的人也比较少。文档也很少。
安装参考:或者直接下载官网上做好的虚拟机。

其它需要花时间研究一下:
1. 逃生方案:fail-open 当准入系统故障时怎么处理------集群,或设置逃生返回VLAN
2. 用户自动注册------待研究
3. LDAP认证--- OK
4. 接入安全扫描检查-----配置snort Server做接口
