What is Radius in telecommunication domain?

RADIUS stands for Remote Authentication Dial-In User Service 

  • it is a client/server security protocol
  • used for control user authentication
  • used for monitoring and control user profiles such as service package, speed, user groups, IP, session time
  • records internet user accounting - session time, connection start/stop, bandwidth usage included the reason for connection ending
  • used for real-time controlling online users - clear session, restrict authentication
  • the clients will connect to the Network Access Server (NAS) as medium server for authentication instead of directly communicating with the RADIUS

2>&1 in command means??

References.. 0 =  standard input  ( stdin ) 1 =  standard output  ( stdout )  2 =  standard error  ( stderr ) Hence, we can use command > output.log to print the std output stream, which is an implicit meaning of command 1>output.log Thus, the annex 2>&1 means print the std error to the same place as the std output.  Moreover, the we can hide the std output from printing out by using 2>/dev/null.
