tacplus.conf(5)

NAME

tacplus.conf - TACACS+ client configuration file

SYNOPSIS

/etc/tacplus.conf

DESCRIPTION

tacplus.conf contains the information necessary to configure

the TACACS+
client library. It is parsed by tac_config() (see libtac

plus(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 com

ments.

A TACACS+ server is described by two to four fields on a

line. The
fields are separated by white space. The `#' 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 `#' character. Within a

quoted string,
the double quote character can be represented by `
can be represented by `´. No other escape sequences are

supported.

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 `:' and a numeric port number, without inter

vening white
space. If the port specification is omitted, it defaults to

49, the
standard TACACS+ port.

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.

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.

The optional fourth field may contain the string `single

connection'. If
this option is included, the library will attempt to negoti

ate with the
server to keep the TCP connection open for multiple ses

sions. Some older
TACACS+ servers become confused if this option is specified.

Up to 10 TACACS+ servers may be specified. The servers are

tried in
order, until a valid response is received or the list is ex

hausted.

The standard location for this file is /etc/tacplus.conf.

An alternate
pathname may be specified in the call to tac_config() (see libtacplus(3)). Since the file contains sensitive informa

tion in the
form of the shared secrets, it should not be readable except

by root.
