HI, I am trying to integrate FreeRadius and JRadius. I am using FreeRadius 2.1.8 and JRadius version 1.1.2 When I am running both the servers and sending any test packets to FreeRadius. I am getting Acces-Accept at FreeRadius side but it is not forwarding Packet to JRadius. I am getting the following log on FreeRadius side.. rlm_jradius: Reserving JRadius socket id: 7 rlm_jradius: packing attribute User-Name (type: 1; len: 8) rlm_jradius: packing attribute User-Password (type: 2; len: 6) rlm_jradius: packing attribute NAS-IP-Address (type: 4; len: 4) rlm_jradius: packing attribute Client-IP-Address (type: 1052; len: 4) rlm_jradius: packing attribute Module-Failure-Message (type: 1076; len: 24) rlm_jradius: packing packet with code: 1 (attr length: 106) rlm_jradius: packing packet with code: 0 (attr length: 0) rlm_jradius: packing attribute User-Password (type: 2; len: 6) rlm_jradius: packing attribute Auth-Type (type: 1000; len: 4) rlm_jradius: sending 172 bytes to socket 7 rlm_jradius: error sending request with socket 7 rlm_jradius: Closing JRadius connection 7 rlm_jradius: reconnecting socket id 7 rlm_jradius: sending 172 bytes to socket 7 rlm_jradius: error sending request with socket 7 rlm_jradius: problem packing the data[socket_send/first_read] rlm_jradius: Closing JRadius connection 7 rlm_jradius: Released JRadius socket id: 7 And at JRadius side I am getting the following logs: java.nio.BufferUnderflowException at java.nio.Buffer.nextGetIndex(Unknown Source) at java.nio.HeapByteBuffer.getInt(Unknown Source) at net.jradius.packet.Format.getUnsignedInt(Format.java:324) at net.jradius.freeradius.FreeRadiusListener.parseRequest(FreeRadiusListener.java:98) at net.jradius.server.ListenerRequest.getEventFromListener(ListenerRequest.java:78) at net.jradius.server.TCPListenerRequest.accept(TCPListenerRequest.java:70) at net.jradius.server.KeepAliveListener.run(KeepAliveListener.java:61) Please help me to understand the problem. whether the two versions are not compatible.
