It is parsed by 39.Xr tac_config 3 . 40The file contains one or more lines of text, each describing a 41single TACACS+ server which is to be used by the library. Leading 42white space is ignored, as are empty lines and lines containing 43only comments. 44.Pp 45A TACACS+ server is described by two to four fields on a line. The 46fields are separated by white space. The 47.Ql # 48character at the beginning of a field begins a comment, which extends 49to the end of the line. A field may be enclosed in double quotes, 50in which case it may contain white space and/or begin with the 51.Ql # 52character. Within a quoted string, the double quote character can 53be represented by 54.Ql \e\&" , 55and the backslash can be represented by 56.Ql \e\e . 57No other escape sequences are supported. 58.Pp 59The first field specifies 60the server host, either as a fully qualified domain name or as a 61dotted-quad IP address. The host may optionally be followed by a 62.Ql \&: 63and a numeric port number, without intervening white space. If the 64port specification is omitted, it defaults to 49, the standard TACACS+ 65port. 66.Pp 67The second field contains the shared secret, which should be known 68only to the client and server hosts. It is an arbitrary string 69of characters, though it must be enclosed in double quotes if it 70contains white space or is empty. An empty secret disables the 71normal encryption mechanism, causing all data to cross the network in 72cleartext. 73.Pp 74The third field contains a decimal integer specifying the timeout 75in seconds for communicating with the server. The timeout applies 76separately to each connect, write, and read operation. If this field 77is omitted, it defaults to 3 seconds. 78.Pp 79The optional fourth field may contain the string 80.Ql single-connection . 81If this option is included, the library will attempt to negotiate 82with the server to keep the TCP connection open for multiple 83sessions. Some older TACACS+ servers become confused if this option 84is specified. 85.Pp 86Up to 10 TACACS+ servers may be specified. The servers are tried in 87order, until a valid response is received or the list is exhausted. 88.Pp 89The standard location for this file is 90.Pa /etc/tacplus.conf . 91An alternate pathname may be specified in the call to 92.Xr tac_config 3 . 93Since the file contains sensitive information in the form of the 94shared secrets, it should not be readable except by root. 95.Sh FILES 96.Pa /etc/tacplus.conf 97.Sh EXAMPLES 98.Bd -literal 99# A simple entry using all the defaults: 100tacserver.domain.com OurLittleSecret 101 102# A server using a non-standard port, with an increased timeout and 103# the "single-connection" option. 104auth.domain.com:4333 "Don't tell!!" 15 single-connection 105 106# A server specified by its IP address: 107192.168.27.81 $X*#..38947ax-+= 108.Ed 109.Sh SEE ALSO 110.Xr libtacplus 3 111.Sh AUTHORS 112This documentation was written by 113.An John Polstra , 114and donated to the FreeBSD project by Juniper Networks, Inc. 115
