INSTALL

NOTE: Change release 3.1.0 onwards
----------------------------------
Due to differences in release levels of the GNU autotools on different 
platforms we are no longer including the configure script as part 
of the distribution.

NOTE: For v5 - please read notes/NEWIN_v5 first!
------------------------------------------------

HOW TO BUILD:
-------------
The distribution uses GNU autotools for building.

Run ./autogen.sh or autoreconf after downloading and unpacking
to (re)generate the configure script and Makefile.in files.

Most users should then follow the standard
"./configure; make; make install" process common to UNIX packages.  

Please read the sections below for your OS for the most widely used
configuration options.

*** xBSD users, please ensure you have bash1 installed first ***

*** Debian and Ubuntu users, please read the Debian section first. ***

*** OS X / Darwin users, please read the OS X section first. ***

1.	  Run the ./autogen.sh script to generate the configure script.
	If an error occurs in running autogen.sh or ./configure then
	make sure you have an up-to-date version of automake tools and 
	then run autoreconf.

2.        Run the configure (./configure --help) script with
        the help option to see the user selectable settings.
        Default settings are shown in [].

3.        Run the configure (./configure) script with your
        options, if any.  It is HIGHLY LIKELY that you will
        want to change some options.  Please read down for
        suggested options for your platform.

4.        "make"** or "gmake" will now build E2Guardian.

5.        "make install" will create the directory structure and install
        all the files in the chosen paths.  For a more efficient
        install, try "make install-strip" which will strip symbol
	information to the DG binary smaller.

6.        "make clean" will remove the now un-needed object files etc.

7.        See the section later called ADDITIONAL SCRIPTS to add
        log rotation, optional CGI block page, startup scripts etc.


** You can often use "make -j 2" or "make -j 5" to compile DG faster,
   especially on multiple CPU computers.  As a general rule of thumb,
   use the number of CPUs/cores plus one.
   With Solaris and others you may need "gmake" instead of "make".
   


OPTIONS:
--------
`configure' configures e2guardian to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
			  [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
			  [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]

See ./configure --help for more details.


MACOSX:
-------

*** Note in order to do any compiling in OS X you need to install ***
*   the Developer Tools - an additional pkg called BSDSDK.pkg.      *

A standard configure script that should work, provided you have installed
MACOSX and the associated programs in their default locations.

    ./configure --localstatedir=/var \
        --mandir=/usr/share/man/ \
        --bindir=/usr/local/sbin/

You might consider changing the location of the log files to
'--with-logdir=/usr/local/e2guardian/logs/' and use the provided
log rotation script.  Alternatively stick with the default
(/var/log/e2guardian/) and read newsyslog(8).


DEBIAN:

Other Packages suggests to E2guardian: squid, clamav, clamav-freshclam
Autogen is needed !

Eg:
./autogen.sh && ./configure  '--prefix=/usr' '--enable-clamd=yes' '--with-proxyuser=e2guardian' '--with-proxygroup=e2guardian' '--sysconfdir=/etc' '--localstatedir=/var' '--enable-icap=yes' '--enable-commandline=yes' '--enable-email=yes' '--enable-ntlm=yes' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--enable-pcre=yes' '--enable-sslmitm=yes' 'CPPFLAGS=-mno-sse2 -g -O2' && make

NETBSD:
-------

A standard configure script that should work, provided you have installed
NetBSD and the associated programs in their default locations.
    ./configure  --localstatedir=/var \
        --prefix=/usr/pkg
        --sysconfdir=/usr/pkg/etc \
        --bindir=/usr/pkg/sbin/

For NetBSD you might consider changing the location of the log files
to '--with-logdir=/usr/local/e2guardian/logs/' and use the
provided log rotation script.  Alternatively stick with the default
(/var/log/e2guardian/) and read newsyslog(8).
Be sure that /usr/sbin/ is in your PATH before make install (for chown).


FREEBSD:
--------
A standard configure script that should work, provided you have installed
FreeBSD and the associated programs in their default locations.

    ./configure  --localstatedir=/var

For FreeBSD and OpenBSD you might consider changing the location of the
log files to '--with-logdir=/usr/local/e2guardian/logs/' and use the
provided log rotation script.  Alternatively stick with the default
(/var/log/e2guardian/) and read newsyslog(8).


OPENBSD:
--------
A standard configure script that should work, provided you have installed
OpenBSD and the associated programs in their default locations.

    ./configure  --localstatedir=/var \
        --bindir=/usr/sbin \
        --mandir=/usr/share/man \
        --sysconfdir=/etc


HOW TO CONFIGURE:
-----------------

Edit the e2guardian.conf, e2guardianf1.conf and other files.
The files are commented well.




ADDITIONAL SCRIPTS:
-------------------

In /usr/local/share/e2guardian/scripts (or wherever you configured
it to be) you will find at least the following files:
bsd-init - a BSD style startup script to be put in your rc.d
solaris-init - a Solaris style startup script to be put in your rc.d
systemv-init - a Linux style startup script to be put in your rc.d
e2guardian.service - a Linux style startup script to be put in your systemd directory
e2guardian - a logrotate.d file
logrotation - a sh script to rotate the logs
../e2guardian.pl - a cgi script for an access denied page

The installation of startup scripts is
deemed out of the scope of source code and is the playground of
packagers and sysadmins.

This is also true of log rotation scripts.  You can choose to use
the example logrotate.d file or you could crontab the logrotation
script thus:
crontab -e
59 23 * * sat /usr/local/share/e2guardian/scripts/logrotation
(now save)
I.e. 23:59 every Saturday.  Or change to as pleases you.

If you wish to use the cgi denied script rather than the template
html denied page you will find it in:
/usr/local/share/e2guardian/ (or wherever you configured it to
be).  This is not usually recommended but if you do want to do
this copy it to your web servers' cgi-bin directory.
E2Guardian.



HOW TO RUN:
-----------

You can start it by just running the binary.  You can stop it by
appending a ' -q' to the end, thus: 'e2guardian -q'.  Or you can use
the SysV(-like) script provided.
