Hi I have following proxy configuration: Hi, I have following proxy configuration for 3rd party server (only piece of the configuration). .... require_message_authenticator = yes type = auth+acct port = 1812 # Status check via existing user status_check = request check_interval = 6 num_answers_to_alive = 3 username = "orange-system" password = "incorrect" # We don't need Access-Accept, enough is Access-Reject .... My server recieves only auth/autz requests which are proxied to 3rd party servers. In case of 3rd party unavailability the server sends request to check status of the 3rd party server. Question is why does server send Accounting Request instead of Access Accept ? Another question for clarification: If i use type=auth+acct, what is correct value for the port ? Is it correct port=1812 ? 15:34:29.016422 IP (tos 0x0, ttl 64, id 8072, offset 0, flags [none], proto: UDP (17), length: 118) tdrad1.vas.orange.sk.59157 > 10.14.135.19.radius: [udp sum ok] RADIUS, length: 90 Accounting Request (4), id: 0xea, Authenticator: 50365561fa7ae6cca5a956834b05dea8 Username Attribute (1), length: 15, Value: orange-system 0x0000: 6f72 616e 6765 2d73 7973 7465 6d Accounting Status Attribute (40), length: 6, Value: Stop 0x0000: 0000 0002 Accounting Session ID Attribute (44), length: 10, Value: 00000000 0x0000: 3030 3030 3030 3030 Event Timestamp Attribute (55), length: 6, Value: Mon Sep 21 15:34:29 2015 0x0000: 5600 0765 NAS ID Attribute (32), length: 33, Value: Status Check 64.
