Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script). Here is a another example:
/bin/bash ./configure CONFIG_SHELL=/bin/bash
Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
configuration-related scripts to be executed by `/bin/bash'.
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## dummy dependencies for each header file. Too bad gcc doesn't do

.SH NAME
xhost \- server access control program for X
.SH SYNOPSIS
.B xhost
[[+\-]name ...]
.SH DESCRIPTION
The \fIxhost\fP program
is used to add and delete host names or user names to the list allowed
to make connections to the X server. In the case of hosts, this provides
a rudimentary form of privacy control and security. It is only sufficient
for a workstation (single user) environment, although it does limit the
worst abuses. Environments which require more sophisticated measures should
implement the user-based mechanism or use the hooks in the
protocol for passing other authentication data to the server.
.SH OPTIONS
\fIXhost\fP accepts the following command line options described below. For
security, the options that effect access control may only be run from the
"controlling host". For workstations, this is the same machine as the
server. For X terminals, it is the login host.
.TP 8
.B \-help
Prints a usage message.
.TP 8
.BI "[+]" "name"
The given \fIname\fP (the plus sign is optional)
is added to the list allowed to connect to the X server.
The name can be a host name or a user name.
.TP 8
.BI \- "name"
The given \fIname\fP is removed from the list of allowed
to connect to the server. The name can be a host name or a user name.
Existing connections are not broken, but new
connection attempts will be denied.
Note that the current machine is allowed to be removed; however, further
connections (including attempts to add it back) will not be permitted.
Resetting the server (thereby breaking all connections)
is the only way to allow local connections again.
.TP 8
.B \+
Access is granted to everyone, even if they aren't on the list
(i.e., access control is turned off).
.TP 8
.B \-
Access is restricted to only those on the list
(i.e., access control is turned on).
.TP 8
.I nothing
If no command line arguments are given,
a message indicating whether or not access control is currently enabled
is printed, followed by the list of those allowed to connect.
This is the only option that may be used from machines other than
the controlling host.
.SH NAMES
A complete name has the syntax
``family:name'' where the families are
as follows:
.PP
.nf
.ta 1i
inet Internet host (IPv4)
inet6 Internet host (IPv6)
dnet DECnet host
nis Secure RPC network name
krb Kerberos V5 principal
local contains only one name, the empty string
si Server Interpreted
.fi
.PP
The family is case insensitive.
The format of the name varies with the family.
.PP
When Secure RPC is being used, the
network independent netname (e.g., "nis:unix.\fIuid\fP@\fIdomainname\fP") can
be specified, or a local user can be specified with just the username
and a trailing at-sign (e.g., "nis:pat@").
.PP
For backward compatibility with pre-R6 \fIxhost\fP,
names that contain an at-sign (@) are assumed to be in the nis family.
Otherwise they are assumed to be Internet addresses. If compiled to support
IPv6, then all IPv4 and IPv6 addresses returned by getaddrinfo(3) are added to
the access list in the appropriate inet or inet6 family.
.PP
Server interpreted addresses consist of a case-sensitive type tag and a
string representing a given value, separated by a colon. For example,
"si:hostname:almas" is a server interpreted address of type \fIhostname\fP,
with a value of \fIalmas\fP.
.SH DIAGNOSTICS
For each name added to the access control list,
a line of the form "\fIname\fP being added to access control list"
is printed.
For each name removed from the access control list,
a line of the form "\fIname\fP being removed from access control list"
is printed.
.SH FILES
/etc/X*.hosts
.SH "SEE ALSO"
X(__miscmansuffix__), Xsecurity(__miscmansuffix__), Xserver(1), xdm(1), xauth(1), getaddrinfo(3)
.SH ENVIRONMENT
.TP 8
.B DISPLAY
to get the default host and display to use.
.SH BUGS
.PP
You can't specify a display on the command line because
.B \-display
is a valid command line argument (indicating that you want
to remove the machine named
.I ``display''
from the access list).
.PP
The X server stores network addresses, not host names, unless you use
the server-interpreted hostname type address. If somehow you change a
host's network address while the server is still running, and you are
using a network-address based form of authentication, \fIxhost\fP must
be used to add the new address and/or remove the old address.
