Hi, I am trying to setup radsec using freeradius version 3.0.3. I have generated self-signed certificate on my freeradius server using openssl commands. I generates .pem and .pfx certificate. I have placed the same files in certs folder of raddb and edited tls file respectively. Command to send radius request: radtest test 456 localhost 2083 testing123 When I run the above command I could see that request is going on 1812 port. Then i checked netstat command to check ports opened for radiusd. TCP port 2083 is not opened. How to open up TCP port and any extra parameters needs to be present in radtest command? Thanks, Kavya
