Hi, I am beginner. I installed Freeradius in my windows PC. With default configuration it works as expected. Now I have a RADIUS client which will send request to server and I want server to authenticate the same. I should be changing users.conf raduser User-Password == "Password" where User-name = "raduser" and Password = "Password" I will have to change clients.conf as well. client <ipaddr/mask>{ secret = secret shortname = client name # what is the significance of shortname } In radiusd.conf, I have changed to which Ip and port RADIUS server has to listen to. (optional) After doing respective changes, I will execute following command: radtest raduser Password 10.253.6.11 1812 Password The result is as follows: C:\FreeRADIUS.net\bin>radclient.exe -d ..\etc\raddb -f radtest.txt -x -s 127.1 au th testing123 Sending Access-Request of id 108 to 127.0.0.1 port 1812 User-Name = "testuser" User-Password = "testpw" NAS-IP-Address = 127.0.0.1 NAS-Port = 123 rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=108, length=20 Total approved auths: 1 Total denied auths: 0 Total lost auths: 0 Here I would like to know why am I getting reply from 127.0.0.1 when I have explicitly asked to receive from 10.253.6.11 PFA the debug log. Thanks in advance, Kavya
