.Dt RADIUS.CONF 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm radius.conf
|
|
.Nd RADIUS client configuration file
|
|
.Sh SYNOPSIS
|
|
.Pa /etc/radius.conf
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
contains the information necessary to configure the RADIUS client
|
|
library.
|
|
It is parsed by
|
|
.Xr rad_config 3 .
|
|
The file contains one or more lines of text, each describing a
|
|
single RADIUS server which will be used by the library.
|
|
Leading
|
|
white space is ignored, as are empty lines and lines containing
|
|
only comments.
|
|
.Pp
|
|
A RADIUS server is described by three to five fields on a line:
|
|
.Pp
|
|
.Bl -item -offset indent -compact
|
|
.It
|
|
Service type
|
|
.It
|
|
Server host
|
|
.It
|
|
Shared secret
|
|
.It
|
|
Timeout
|
|
.It
|
|
Retries
|
|
.El
|
|
.Pp
|
|
The fields are separated by white space.
|
|
The
|
|
.Ql #
|
|
character at the beginning of a field begins a comment, which extends
|
|
to the end of the line.
|
|
A field may be enclosed in double quotes,
|
|
in which case it may contain white space and/or begin with the
|
|
.Ql #
|
|
character.
|
|
Within a quoted string, the double quote character can
|
|
be represented by
|
|
.Ql \e\&" ,
|
|
and the backslash can be represented by
|
|
.Ql \e\e .
|
|
No other escape sequences are supported.
|
|
.Pp
|
|
.Pp
|
|
The first field gives the service type, either
|
|
.Ql auth
|
|
for RADIUS authentication or
|
|
.Ql acct
|
|
for RADIUS accounting.
|
|
If a single server provides both services, two
|
|
lines are required in the file.
|
|
Earlier versions of this file did
|
|
not include a service type.
|
|
For backward compatibility, if the first
|
|
field is not
|
|
.Ql auth
|
|
or
|
|
.Ql acct
|
|
the library behaves as if
|
|
.Ql auth
|
|
were specified, and interprets the fields in the line as if they
|
|
were fields two through five.
|
|
.Pp
|
|
The second field specifies
|
|
the server host, either as a fully qualified domain name or as a
|
|
dotted-quad IP address.
|
|
The host may optionally be followed by a
|
|
.Ql \&:
|
|
and a numeric port number, without intervening white space.
|
|
If the
|
|
port specification is omitted, it defaults to the
|
|
.Ql radius
|
|
or
|
|
.Ql radacct
|
|
service in the
|
|
.Pa /etc/services
|
|
file for service types
|
|
.Ql auth
|
|
and
|
|
.Ql acct ,
|
|
respectively.
|
|
If no such entry is present, the standard ports 1812 and 1813 are
|
|
used.
|
|
.Pp
|
|
The third field contains the shared secret, which should be known
|
|
only to the client and server hosts.
|
|
It is an arbitrary string of
|
|
characters, though it must be enclosed in double quotes if it
|
|
contains white space.
|
|
The shared secret may be
|
|
any length, but the RADIUS protocol uses only the first 128
|
|
characters.
|
|
N.B., some popular RADIUS servers have bugs which
|
|
prevent them from working properly with secrets longer than 16
|
|
characters.
|
|
.Pp
|
|
The fourth field contains a decimal integer specifying the timeout in
|
|
seconds for receiving a valid reply from the server.
|
|
If this field
|
|
is omitted, it defaults to 3 seconds.
|
|
.Pp
|
|
The fifth field contains a decimal integer specifying the maximum
|
|
number of attempts that will be made to authenticate with the server
|
|
before giving up.
|
|
If omitted, it defaults to 3 attempts.
|
|
Note,
|
|
this is the total number of attempts and not the number of retries.
|
|
.Pp
|
|
Up to 10 RADIUS servers may be specified for each service type.
|
|
The servers are tried in
|
|
round-robin fashion, until a valid response is received or the
|
|
maximum number of tries has been reached for all servers.
|
|
.Pp
|
|
The standard location for this file is
|
|
.Pa /etc/radius.conf .
|
|
But an alternate pathname may be specified in the call to
|
|
.Xr rad_config 3 .
|
|
Since the file contains sensitive information in the form of the
|
|
shared secrets, it should not be readable except by root.
