.Dt TACPLUS.CONF 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm tacplus.conf
|
|
.Nd TACACS+ client configuration file
|
|
.Sh SYNOPSIS
|
|
.Pa /etc/tacplus.conf
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
contains the information necessary to configure the TACACS+ client
|
|
library.
|
|
It is parsed by
|
|
.Fn tac_config
|
|
(see
|
|
.Xr libtacplus 3 ) .
|
|
The file contains one or more lines of text, each describing a
|
|
single TACACS+ server which is to be used by the library.
|
|
Leading
|
|
white space is ignored, as are empty lines and lines containing
|
|
only comments.
|
|
.Pp
|
|
A TACACS+ server is described by two to four fields on a line.
|
|
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
|
|
The first 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 49, the standard TACACS+
|
|
port.
|
|
.Pp
|
|
The second 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 or is empty.
|
|
An empty secret disables the
|
|
normal encryption mechanism, causing all data to cross the network in
|
|
cleartext.
|
|
.Pp
|
|
The third field contains a decimal integer specifying the timeout
|
|
in seconds for communicating with the server.
|
|
The timeout applies
|
|
separately to each connect, write, and read operation.
|
|
If this field
|
|
is omitted, it defaults to 3 seconds.
|
|
.Pp
|
|
The optional fourth field may contain the string
|
|
.Ql single-connection .
|
|
If this option is included, the library will attempt to negotiate
|
|
with the server to keep the TCP connection open for multiple
|
|
sessions.
|
|
Some older TACACS+ servers become confused if this option
|
|
is specified.
|
|
.Pp
|
|
Up to 10 TACACS+ servers may be specified.
|
|
The servers are tried in
|
|
order, until a valid response is received or the list is exhausted.
|
|
.Pp
|
|
The standard location for this file is
|
|
.Pa /etc/tacplus.conf .
|
|
An alternate pathname may be specified in the call to
|
|
.Fn tac_config
|
|
(see
|
|
.Xr libtacplus 3 ) .
|
|
Since the file contains sensitive information in the form of the
|
|
shared secrets, it should not be readable except by root.
