Hello, im debugging a problem in a Freeradius/Mikrotik setup with 3 NAS and 1 Freeradius setup, ~ 3K users online....and getting Stale Sessions, after a lot of googling and digging i found something curious... Accounting requests Packets do include the Acct-Session-Time attribute, which the RFC says should only go only if Acct-Status-Type is a STOP one.... Am I missing something here? How does freeradius act on this case? Also, Timestamp is UTC, while mysql shows local time....is this ok? Example packet: Accounting-Request Id 209 10.0.0.11:34077 -> 10.0.0.1:1813 +1199.991 Service-Type = Framed-User Framed-Protocol = PPP NAS-Port = 671504 NAS-Port-Type = Ethernet User-Name = "1234566" Calling-Station-Id = "00:12:22:A0:bb:5C" Called-Station-Id = "Remota ffgdfg ffffff" NAS-Port-Id = "Vlan dfg rerererer" Acct-Session-Id = "8105f258" Framed-IP-Address = 123.111.222.333 Acct-Authentic = RADIUS Event-Timestamp = "Apr 14 2012 21:23:42 UTC" Acct-Session-Time = 1500 Acct-Input-Octets = 2852 Acct-Input-Gigawords = 0 Acct-Input-Packets = 74 Acct-Output-Octets = 5721 Acct-Output-Gigawords = 0 Acct-Output-Packets = 95 Acct-Status-Type = Interim-Update NAS-Identifier = "XXX_PPPoE_1" Acct-Delay-Time = 0 NAS-IP-Address = 10.0.0.11 Accounting-Response Id 209 10.0.0.1:1813 -> 10.0.0.11:34077 +1200.000 thanks!
