2.SH NAME
3hosts_access \- format of host access control files
4.SH DESCRIPTION
5This manual page describes a simple access control language that is
6based on client (host name/address, user name), and server (process
7name, host name/address) patterns. Examples are given at the end. The
8impatient reader is encouraged to skip to the EXAMPLES section for a

86.IP \(bu
87An expression of the form `n.n.n.n/m.m.m.m\' is interpreted as a
88`net/mask\' pair. A host address is matched if `net\' is equal to the
89bitwise AND of the address and the `mask\'. For example, the net/mask
90pattern `131.155.72.0/255.255.254.0\' matches every address in the
91range `131.155.72.0\' through `131.155.73.255\'.
92.IP \(bu
93A string that begins with a `/\' character is treated as a file
94name. A host name or address is matched if it matches any host name
95or address pattern listed in the named file. The file format is
96zero or more lines with zero or more host name or address patterns
97separated by whitespace. A file name pattern can be used anywhere
98a host name or address pattern can be used.
