Radius acctstarttime

[Oscar Jofre]

Thanks Alan,

 

So just for clarify:

 

  So if both the NAS and FreeRADIUS use NTP for the correct time, they should have the same time.

 

In Taiwan’s NAS I have NTP and the NAS clock is 2018-03-25 07:29:16 am

 



 

 

And when a write on radius comes from that router it saves as 2018-03-25 00:29:16 am ... the time from the centos where is installed freeradius.

 

So if the NAS have an incorrect time (could not sync with NTP) will save an incorrect time on raddact ?

 

 

Thanks,

  No.  Acct-Start-Time is sent by the NAS.  FreeRADIUS just writes it in the DB.

  Because the time on the NAS is wrong.

  Exactly.

  It comes from the NAS.

  The NAS sends the time to FreeRADIUS as a 32-bit number.  NOT as a printable string.  And there's no time zone information.  FreeRADIUS takes this time, converts it to a string, and writes it to the DB.

 

  So if both the NAS and FreeRADIUS use NTP for the correct time, they should have the same time.
