32 .Nd RADIUS client configuration file
37 contains the information necessary to configure the RADIUS client
41 The file contains one or more lines of text, each describing a
42 single RADIUS server which will be used by the library.
44 white space is ignored, as are empty lines and lines containing
47 A RADIUS server is described by three to seven fields on a line:
49 .Bl -item -offset indent -compact
66 The fields are separated by white space.
69 character at the beginning of a field begins a comment, which extends
70 to the end of the line.
71 A field may be enclosed in double quotes,
72 in which case it may contain white space and/or begin with the
75 Within a quoted string, the double quote character can
78 and the backslash can be represented by
80 No other escape sequences are supported.
82 The first field gives the service type, either
84 for RADIUS authentication or
86 for RADIUS accounting.
87 If a single server provides both services, two
88 lines are required in the file.
89 Earlier versions of this file did
90 not include a service type.
91 For backward compatibility, if the first
96 the library behaves as if
98 were specified, and interprets the fields in the line as if they
99 were fields two through five.
101 The second field specifies
102 the server host, either as a fully qualified domain name or as a
103 dotted-quad IP address.
104 The host may optionally be followed by a
106 and a numeric port number, without intervening white space.
108 port specification is omitted, it defaults to the
114 file for service types
119 If no such entry is present, the standard ports 1812 and 1813 are
122 The third field contains the shared secret, which should be known
123 only to the client and server hosts.
124 It is an arbitrary string of
125 characters, though it must be enclosed in double quotes if it
126 contains white space.
127 The shared secret may be
128 any length, but the RADIUS protocol uses only the first 128
130 N.B., some popular RADIUS servers have bugs which
131 prevent them from working properly with secrets longer than 16
134 The fourth field contains a decimal integer specifying the timeout in
135 seconds for receiving a valid reply from the server.
137 is omitted, it defaults to 3 seconds.
139 The fifth field contains a decimal integer specifying the maximum
140 number of attempts that will be made to authenticate with the server
142 If omitted, it defaults to 3 attempts.
144 this is the total number of attempts and not the number of retries.
146 The sixth field contains a decimal integer specifying a time interval
147 in seconds when the server will not requested if it was inaccessible
148 on the last try. 0 means ask always.
150 The seventh field contains an IP address on multihomed host. All
151 requests will be binded to this IP.
153 Up to 10 RADIUS servers may be specified for each service type.
154 The servers are tried in
155 round-robin fashion, until a valid response is received or the
156 maximum number of tries has been reached for all servers.
158 The standard location for this file is
159 .Pa /etc/radius.conf .
160 But an alternate pathname may be specified in the call to
162 Since the file contains sensitive information in the form of the
163 shared secrets, it should not be readable except by root.
