اگه از NttacPlus استفاده می کنی
Use of session-timeout
When you check the Session-Timeout option, as mentioned above, NTTacPlus computes during a user login the maximum length of the session for that user, sending to the NAS the result in the Session-Timeout attribute. After this time it’s up to the NAS to end the session. No command is explicitly sent by NTTacPlus.
The value transmitted in the Session Timeout attribute will be computed as the minimum value among the following ones: (see the chapter Account Management if you need further information about individual parameters):
• Maximum length of a single session (MaxConnectionTime)
• Residual time quota for the current period (QuotaLeft)
• Residual time credit for the account (TimeLeft)
Each of these parameters will be evaluated only if the account is configured to have a limitation on that parameter and only if the account is configured to be disconnected forcibly when this parameter is going to exhaust.
Otherwise, the Session-Timeout attribute won’t be sent to the NAS, and no implicit restrictions will be placed for the session.
NOTE: This method works correctly only with the RADIUS authentication and if the NAS supports the Session-Timeout attribute. Through this method it is not possible to kill manually a user session from the Edit/Kill command of the Remote Console.
