[newbie] radutmp question

[Cheng-Lin Yang]

Hi all,
I have encountered a problem with radutmp. The information of my
environment is a vpn service and auth with freeradius 1.1.7. The
problem happened as below:

1. start up the radiusd
2. user "abc" connect to vpn, and I can use radwho to see "abc" user
3. shutdown radiusd
4. user disconnect from vpn server (radiusd not start yet)
5. start up radiusd, and radwho still shows "abc" is connected

Is there any way to solve this problem? any suggestion is extremely
welcomed. Thank you. :)

Regards,
clyang
