Topic: TekRADIUS.exe high CPU usage
Delete operations put extra load on SQL server. Incoming RADIUS requests cannot be processed in timely manner when you have high load on the SQL server and this may cause high CPU usage. Your SQL server probably needs some fine tuning.

Hi,


Can you increase interim update period for 10.9.5.3 from 300 to 350 in TekRADIUS Manager / Clients tab? You do not change any settings in
your access controller or access point.


TekRADIUS clears an active session entry for station "A" if it does not receive an accounting interim update for the active session of station "A" specified in TekRADIUS Manager / Clients tab.
Another station "B" can connect when an active session entry is cleared. TekRADIUS re-creates active session entry if timed out checkpoint packet is received for station "A" but
session of station "B" stays active.


I can implement a new feature to disconnect station "B" in such cases if your system supports RADIUS packet of disconnect.


Best regards,

Hi,

today after update to 5.3.4.21 and cleaning all sessions from active session tab, TekRADIUS.exe has high CPU load 99%. I could make a wireshark Trace.
I have started the trace in the problem situation. About at Frame 10500 I killed TekRADIUS.exe in taskmanager and did a normal start in windows service manager. Maybe you can see any difference from problem situation to normal situation.

You recieve the trace as mail over 6MB.

Best regards

Hi,

the update I have installed todays morning around 7:30am. After installing and restarting I did as always: In TekRADIUS manager -> mark active sessions “Clear with accounting stop”. Sessions tab was empty. After a short time I have seen the picture I mail you now: Singh.Jasvinder has a double login in the SSID UMA which should not be allowed AND before I did a “Clear with accounting stop” Singh.Jasvinder’s and feyerabendt.antonia’s session was not visible in active sessions. Here you get the log file from today.

Picture is from today around 7:30am.

Best regards

Hi,

at this time I see not real double logins. But I think I know what the problem could be.

For both users it is possible to login to the SSID "UMA" and also "BEWOHNER3259". But SSID "BEWOHNER3259" should be forbidden for this users because they don't belong to the active dircetory group "AD-WLAN_BEWOHNER". You will recieve the log files and excel tables as mail. In the excel tables you see in red color how they use the wrong SSID.

At same time in log file you find messages like:
10.12.2017 11:43:31.036 - EAP-PEAP Authentication commencing for user 'sukwinder' [3 (182)]

10.12.2017 11:43:31.036 - TLS Session has been established [TLS_RSA_WITH_AES_256_CBC_SHA, TLS version: 1.2] (Group: Default, User: 'sukwinder').

10.12.2017 11:43:31.036 - PEAP Challenge sent for user 'sukwinder' [4 (182), 907bdad86d8cbd446ead19bacd34fe99].

10.12.2017 11:43:31.067 - PEAP Response received.

I think it is a bug because 'sukwinder' is not a real logon name. But Default group allows really "BEWOHNER3259" that is correct.


Background informations:
- SSIDs "UMA" and "BEWOHNER3259" are timed active.
- That Default group allows "BEWOHNER3259" is a workaround, because it is not possible in active directory for the AD group "AD-WLAN_BEWOHNER" that this group is the only primary group!

Hi,

This will not solve the problem but will provide additional diagnostic output to solve the problem.

Ok, now it is really the version 5.3.4.16 but there is now a bigger problem.

NOW
I downgrade it back to version 5.3.4.14

BECAUSE
Today since 04.12.2017 07:49:13 no accounting data is recorded on the SQL database. This is the point of time I update to 5.3.4.15 and for some minutes to 5.3.4.16 but there are absoulte nothing recorded in the database.

NOW
I went back to 5.3.4.14 and accounting works fine in SQL database! Active sessions tab in TekRADIUS Manager works fine! You got the log file as mail.

Correct. It writes 5.3.4.15 in log file, chinese signs and empty active session tab. Also in the unzipped file the exe file shows in properties 5.3.4.15.

Can you confirm that you cannot see "TekRADIUS Service 5.3.4.16 is being started" message in TekRADIUS log?
