Hi, I use radius sqlippool to assign IP address to my users, yesterday, after a restart on radius service, it started to assign IP address that were already in use to the users. I'm almost crazy here, I don't know what can be causing this, we have been using this scheme for at least three months and this problem never happened. freeradius-2.1.12_1 I have this configuration in sites-enabled/default, post-auth block: if (Framed-Protocol == PPP) { sqlippool } and this in the accounting block: sqlippool this in the authorize block: update control { Pool-Name := "%{sql: SELECT nas_pool_name FROM naspool WHERE nas_ip=INET_ATON('%{NAS-IP-Address}')}" } mysql> desc naspool; +---------------+------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------------+------+-----+---------+-------+ | nas_ip | int(10) unsigned | NO | PRI | 0 | | | nas_pool_name | varchar(30) | YES | | NULL | | +---------------+------------------+------+-----+---------+-------+ The strange is that most, if not all of the duplicated address, are between a specific NAS and a random one. Obs. The expiry-time is set on 1h, and the interim update is set on 10m. Any suggestions?
