35 contains the information necessary to configure the TACACS+ client
41 The file contains one or more lines of text, each describing a
42 single TACACS+ server which is to be used by the library.
44 white space is ignored, as are empty lines and lines containing
47 A TACACS+ server is described by a minimum of two fields on a line.
48 The fields are separated by whitespace and follow the same rules for
49 comments, quoting, escaping, and line continuation as the POSIX shell.
51 The first field specifies
52 the server host, either as a fully qualified domain name or as a
53 dotted-quad IP address.
54 The host may optionally be followed by a
56 and a numeric port number, without intervening white space.
58 port specification is omitted, it defaults to 49, the standard TACACS+
61 The second field contains the shared secret, which should be known
62 only to the client and server hosts.
63 It is an arbitrary string
64 of characters, though it must be enclosed in double quotes if it
65 contains white space or is empty.
66 An empty secret disables the
67 normal encryption mechanism, causing all data to cross the network in

71 timeout in seconds for communicating with the server.
