FreeRadius on RHEL 5 gives error "radclient: no response from server for ID 224"

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 5
  • FreeRadius client/server

Issue

  • FreeRadius on RHEL 5 gives error "radclient: no response from server for ID 224"

Resolution

  • In radclient, the second parameter is expected to be a packet type, such as "auth" or "status", or a numerical value that the server can understand in its place; not the port number as used in radtest. Replacing the port value with a valid packet type fixes the issue.

Root Cause

  • The parameters for radclient are slightly different to radtest:
    • Using radtest:
      # radtest user pass radiusserver.example.com 1812 sharedsecret
    • Using radclient:
      # echo "User-Name=user, User-Password=pass" | radclient radiusserver.example.com:1812 auth sharedsecret
  • Port is the parameter after the server in radtest, but uses a colon separator in radclient, with the next parameter being packet type

Diagnostic Steps

  • On client:
    [root@server1.example.com ~]# echo "User-Name=user, User-Password=pass" | radclient radiusserver.example.com 1812 sharedsecret
radclient: no response from server for ID 224
  • On Server:
    [root@radiusserver.example.com ~]# tail -f /var/log/radius/radius.log 
...
