I got radwho to work properly so it would show the user is connected. I also added DEFAULT Simultaneous-Use := 1 Fall-Through = 1 to the users file. I have added the fowling into the database that radius uses. mysql> select * from radgroupcheck; +----+-----------+------------------+----+-------+ | id | groupname | attribute | op | value | +----+-----------+------------------+----+-------+ | 1 | dialup | Simultaneous-Use | := | 1 | +----+-----------+------------------+----+-------+ But then multiple connections are still allowed to be made. I thought I covered everything, what did I miss?

I am looking for a answer on the best way to disable mulitipule logins by the same user. I have been reading http://freeradius.org/radiusd/doc/Simultaneous-Use One problem is I get a error when I try to run radwho radwho: Error reading /var/log/freeradius/sradutmp: No such file or directory This checkrad.pl scrpt I can not find it anywhere on my ubuntu 10.04 server. Where would if find a copy. I do have a radutmp file. Should there be entries in it when no one is connected? So is the only way,to run snmp on the server, or has that way outdated now? Thanks for the help
