32 .Nd TACACS+ client configuration file
37 contains the information necessary to configure the TACACS+ client
38 library. It is parsed by
42 The file contains one or more lines of text, each describing a
43 single TACACS+ server which is to be used by the library. Leading
44 white space is ignored, as are empty lines and lines containing
47 A TACACS+ server is described by two to four fields on a line. The
48 fields are separated by white space. The
50 character at the beginning of a field begins a comment, which extends
51 to the end of the line. A field may be enclosed in double quotes,
52 in which case it may contain white space and/or begin with the
54 character. Within a quoted string, the double quote character can
57 and the backslash can be represented by
59 No other escape sequences are supported.
61 The first field specifies
62 the server host, either as a fully qualified domain name or as a
63 dotted-quad IP address. The host may optionally be followed by a
65 and a numeric port number, without intervening white space. If the
66 port specification is omitted, it defaults to 49, the standard TACACS+
69 The second field contains the shared secret, which should be known
70 only to the client and server hosts. It is an arbitrary string
71 of characters, though it must be enclosed in double quotes if it
72 contains white space or is empty. An empty secret disables the
73 normal encryption mechanism, causing all data to cross the network in
76 The third field contains a decimal integer specifying the timeout
77 in seconds for communicating with the server. The timeout applies
78 separately to each connect, write, and read operation. If this field
79 is omitted, it defaults to 3 seconds.
81 The optional fourth field may contain the string
82 .Ql single-connection .
83 If this option is included, the library will attempt to negotiate
84 with the server to keep the TCP connection open for multiple
85 sessions. Some older TACACS+ servers become confused if this option
88 Up to 10 TACACS+ servers may be specified. The servers are tried in
89 order, until a valid response is received or the list is exhausted.
