I have installed FreeRadius 1.0.5 on the machine which has the Redhat 9 os. I entered" Radtest test test localhost 0 testing123" to check if i had installed FreeRdius correctly and just find the following message: Sending Access-Request of id 77 to 127.0.0.1:1812 User-Name = "test" User-Password = "test" NAS-IP-Address = redhat NAS-Port = 0 Re-sending Access-Request of id 77 to 127.0.0.1:1812 User-Name = "test" User-Password = "\002*\362\230y\233\002\221?\250\027x\027\370\3608" NAS-IP-Address = redhat NAS-Port = 0 .......
