RADIUS clients file

## NAME

clients - RADIUS clients file

## DESCRIPTION

The *clients* file resides in the radius database directory, by default */etc/raddb*. It contains a list of RADIUS clients. Every line starting with a hash sign ('**#**') is treated as comment and ignored.

Each line of the file contains two white-space delimited fields.

- client

  The RADIUS clients hostname This may be a plain hostname, or a dotted-quad IP address.

- secret

  This is the so-called "shared secret" that is held between a RADIUS server and client. It is used to encrypt passwords in RADIUS packets, and also for authentication. You need to configure the same secret on the client (terminal server) as in this file.

The *clients* file is read by **radiusd** on startup only.
