FreeRADIUS：自定义 SQL 计数器仅部分工作

我想在我的 FreeRADIUS 安装中添加一个自定义 SQL 检查计数器。基本上它与 Max-Daily-Session 相同，但仅限于当前Called-Station-Id。

我将其添加到sql / mysql / counter.conf：

sqlcounter dailycounterlocation {
        counter-name = Daily-Session-Location-Time
        check-name = Max-Daily-Session-Location
        reply-name = Session-Timeout
        sqlmod-inst = sql 
        key = User-Name
        reset = daily
        query = "SELECT SUM(acctsessiontime - \ 
             GREATEST((%b - UNIX_TIMESTAMP(acctstarttime)), 0)) \
             FROM radacct WHERE username = '${key}' AND \
             (UNIX_TIMESTAMP(acctstarttime) + acctsessiontime > '%b') \
             AND calledstationid = '%{Called-Station-Id}' "
}

然后在 sites-enabled/default 中：

[...]
authorize {
    dailycounterlocation {
        reject = 1
    }
    if(reject){
        update reply {
            Reply-Message := "You have reached your daily time limit from this location"
        }
        reject
    }
}

最后在自定义词典文件中：

ATTRIBUTE       Max-Daily-Session-Location     107      integer

如果用户在此重置期间（今天）有先前的会话，则此方法有效，但如果这是当天的第一个会话，则Session-Timeout不会返回属性，因此不会强制执行限制。

如果我将工厂添加Max-Daily-Session到用户，则在组 SQL 查询后的第二天第一次连接期间，我会在调试中看到以下内容：

rlm_counter: Current Time: 1425241760 [2015-03-01 21:29:20], Next reset 1425250800 [2015-03-02 00:00:00]
rlm_counter: reset_db: Closing database
rlm_counter: reset_db: Opened new database
rlm_counter: add_defaults: Start
rlm_counter: DEFAULT1 set to 1425250800
rlm_counter: DEFAULT2 set to 1425078000
rlm_counter: add_defaults: End 
rlm_counter: reset_db ended
rlm_counter: Entering module authorize code
rlm_counter: Searching the database for key 'ALG02MAX'
rlm_counter: Could not find the requested key in the database.
rlm_counter: Check item = 200, Count = 0 
rlm_counter: res is greater than zero
rlm_counter: (Check item - counter) is greater than zero
rlm_counter: Authorized user ALG02MAX, check_item=200, counter=0
rlm_counter: Sent Reply-Item for user ALG02MAX, Type=Session-Timeout, value=200
++[daily] = ok

这样，默认值为200返回Session-Timeout（在表中radgroupcheck）。为什么我的计数器没有发生这种情况？我遗漏了什么？谢谢

解决这个问题的方法是在模块配置中添加一个计数器，并从authorize站点配置文件的部分调用它。

另外modules/counter：

 counter dailylocation {
        filename = ${db_dir}/db.daily
        key = User-Name
        count-attribute = Acct-Session-Time
        reset = daily
        counter-name = Max-Daily-Session-Location-Time
        check-name = Max-Daily-Session-Location
        reply-name = Session-Timeout
        allowed-servicetype = Framed-User
        cache-size = 5000
 }

然后sites-enabled/default在 部分中authorize，紧接着daily添加

dailylocation

这将使计数器能够被检查！
