Hi All, This isn't freeradius specific per se but I can't find anything on the web about this. Maybe someone here has experience with this. I'm trying to drop a session using radclient: Sending Disconnect-Request of id 169 to 204.101.13.1 port 1700 User-Name = "someid@example.com" Acct-Session-Id = "erx ip:67.69.123.10:67.69.201.164:1698:d542:29da:ae8e:33d542:002" rad_recv: Disconnect-NAK packet from host 204.101.13.1 port 1700, id=169, length=26 Error-Cause = Session-Context-Not-Found But regardless of what I try I can't seem to send the right attrs to get (ie. find) an active session dropped. The NAS is a Juniper Edge Routing Switch ERX-310. Best I can tell I have the right attrs. Including others results in Unsupported attr error. Omitting either of these two results in attr missing error. Does anybody know the what should be passed? Here is the radacct record for the session: radacctid: 959301 acctsessionid: erx ip:67.69.123.10:67.69.201.164:1698:d542:29da:ae8e:33d542:002 acctuniqueid: d0c22edd21381824 username: someid@example.com groupname: realm: nasipaddress: 204.101.13.1 nasportid: 124498 nasporttype: Virtual acctstarttime: 2015-11-19 10:28:55 acctstoptime: NULL acctsessiontime: 3600 acctauthentic: RADIUS connectinfo_start: connectinfo_stop: NULL acctinputoctets: 6638966 acctoutputoctets: 140935633 calledstationid: callingstationid: GigabitEthernet 5/0/4.1300052:130-52=23587452684=2 acctterminatecause: servicetype: Framed-User framedprotocol: PPP framedipaddress: 204.101.88.246 acctstartdelay: 0 acctstopdelay: NULL xascendsessionsvrkey: Bill
