Freeradius：根据 Nas-IP 地址将组分配给用户

我想知道是否有人可以帮助我。

目标是根据用户所连接的 AP 为不同的用户分配不同的 IP 地址。我无法静态地设置它，因为用户会移动并最终通过不同的 AP 进行连接。

所以我想检查一下我是否可以匹配 nas ip，然后将该用户分配给一个组，然后该组将分配正确的 IP 池。

我做了大量研究，发现这似乎很简单，只需将其添加到 radgroupcheck 表中即可。例如：

 id | groupname |   attribute    |   value    | op 
----+-----------+----------------+------------+----
  1 | Group1    | Nas-IP-Address | x.x.x.x    | ==
  4 | Group1    | Pool-Name      | POOL1      | :=

但是在半径 -X 中我甚至没有看到它尝试检查该组。

它似乎检查了 radusergroup 表，但是由于我需要根据位置动态设置用户组，所以里面没有任何内容。

任何帮助，将不胜感激。

谢谢

我认为你应该能够使用NAS 搜寻组去做你想做的事，

按照示例创建表：

CREATE TABLE radhuntgroup (
    id int(11) unsigned NOT NULL auto_increment,
    groupname varchar(64) NOT NULL default '',
    nasipaddress varchar(15) NOT NULL default '',
    nasportid varchar(15) default NULL,
    PRIMARY KEY  (id),
    KEY nasipaddress (nasipaddress)
) ;

添加您的 NAS 地址：

插入radhuntgroup(组名，nasipaddress) 值 ("Nas_1", "192.168.0.10"); 插入 (radhuntgroup组名，nasipaddress) 值 ("Nas_2", "192.168.1.10");

然后在该authorize {}部分中添加以下代码：

{ Huntgroup-Name := “%{sql:SELECT groupname FROM radhuntgroup WHERE nasipaddress='%{NAS-IP-Address}'}” }

然后，您可以在表中添加行radgroupcheck来检查其他值（如果需要），或者只是radgroupreply在表中添加可以为它们分配特定池的值。

NickW 的回答理论上应该可行。然而出于某种原因，使用 radtest 时它有效，但当我通过 AP 进行身份验证时失败了。我使用的是 EAP，所以 wpa2-enterpise 带有签名证书。（我遵循了这个 指导，请注意我使用的是 centos 服务器而不是 ubuntu )

我最终进入了我的站点启用/默认，在后认证部分，我在 sqlippool 之前添加了它。

update control {
                Pool-Name := "%{sql:select value from radgroupcheck left join radhuntgroup on (radhuntgroup.groupname=radgroupcheck.groupname) where radhuntgroup.nasipaddress ='%{NAS-IP-Address}'}"
    }

我的表格布局是标准的，我按照 NickW 的建议添加了 radhuntgroup，然后将其与我的 radgroupcheck 表格匹配，就像这样

radhuntgroup：

 id |  groupname   | nasipaddress | nasportid 
----+--------------+--------------+-----------
  1 | South Africa | 10.xx.xx.xx  | 
  2 | Mozambique   | 10.xx.xx.xx  |

radgroupcheck：

 id |  groupname   | attribute | op |   value    
----+--------------+-----------+----+------------
  4 | South Africa | Pool-Name | := | ZA_IP_POOL
  7 | Mozambique   | Pool-Name | := | MZ_IP_POOL

所以我的 radiusd -X 中的结果如下
