SCO csh still thinks true is false.  Write to SCO today and tell them that next
year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

(Actually, Configure ought to just patch csh in place.  Hmm.  Hmmmmm.  All
we'd have to do is go in and swap the && and || tokens, wherever they are.)

This installation shell script will examine your system and ask you questions
to determine how the cgiwrap package should be installed. If you get
stuck on a question, you may use a ! shell escape to start a subshell or
execute a command.  Many of the questions will have default answers in square
brackets; typing carriage return will give you the default.

On some of the questions which ask for file or directory names you are allowed
to use the ~name construct to specify the login directory belonging to "name",
even if you don't have a shell which knows about that.  Questions where this is
allowed will be marked "(~name ok)".

EOH
	rp=''
	dflt='Type carriage return to continue'
	. ./myread
	cat <<'EOH'

The prompter used in this script allows you to use shell variables and
backticks in your answers.  You may use $1, $2, etc...  to refer to the words
in the default answer, as if the default line was a set of arguments given to a
script shell.  This means you may also use $* to repeat the whole default line,
so you do not have to re-type everything to add something to the default.

Everytime there is a substitution, you will have to confirm.  If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.

If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
the questions and use the computed defaults (or the previous answers if there
was already a config.sh file). Type 'Configure -h' for a list of options.

EOH
	. ./myread
	cat <<EOH

Much effort has been expended to ensure that this shell script will run on any
Unix system.  If despite that it blows up on yours, your best bet is to edit
Configure and run it again.  Also, let me (cgiwrap@umr.edu)
know how I blew it.  If you can't run Configure for some reason, you'll have to
generate a config.sh file by hand.

This installation script affects things in two ways:

1) it may do direct variable substitutions on some of the files included
   in this kit.
2) it builds a config.h file for inclusion in C programs.  You may edit
   any of these files as the need arises after running this script.

If you make a mistake on a question, there is no easy way to back up to it
currently.  The easiest thing to do is to edit config.sh and rerun all the SH
files.  Configure will offer to let you do this before it runs the SH files.

The next question deals with whether or not you want cgiwrap to verify
that it is being run from the web server. The way it does this is, it
checks it's effective UID and compares that to the userid that the web
server runs as. If they are not the same, and you have this option turned
on, cgiwrap will exit.

Now you need to tell me what userid your web server is running as. Note, 
this is most likely not 'root'. This is usually configured as part of your
server config. You can check which one it is by looking at the child 
httpd processes and seeing who owns them.

The next few questions have to do with whether or not AFS is installed on 
the webserver system. (AFS is the Andrew File System, if you don't know 
what AFS is, or if you aren't sure if it is installed, answer the first

If you answer yes, the questions following will ask you if you want to 
set an AFS PAG for the script you run, and the locations of the AFS 
libraries that will need to be linked in with CGIwrap.

The next question(s) deal with whether you want CGIwrap to restrict it's 
usage only to userids that are listed in a configuration file.  I 
generally enable checking the deny file, and then set up an empty deny 
file. This way, if for some reason I need to temporarily disable a user, 
I can just add them to the deny file without any fuss.

There are two optional files, an allow file or a deny file. If you enable 
the option to check the allow file, only users listed in the allow file 
will be allowed to use CGIwrap. If you enable the option to check the 
deny file, all userids except those that are listed in the deny file will be
allowed to use CGIwrap.

The file format is one userid per line.

The next several questions are for enabling or disabling certain checks 
that are made on the script before allowing it to be executed.

You can enable the check to prevent the script from executing if any of 
the following are true:
	o Script's owner does not match user
	o Script's group does not match user
	o Script is setuid
	o Script is setgid

If any of the chosen checks fail, the script will not be executed, and an
error message will be returned to the user.

CGIwrap has the capability of automatically redirecting the stderr output
to stdout. This means that users can debug their scripts from the web 
browser instead of having to look at the server's error_log to see the error
output from their scripts. I reccomend you leave this as yes.

This feature has actually turned out to be one of the more handy 
capabilities of CGIwrap, particularly when combined with the debugging mode.

I can set things up so that your shell scripts and binaries are more portable,
at what may be a noticable cost in performance.  In particular, if you
ask to be portable, the following happens:

     1) Shell scripts will rely on the PATH variable rather than using
	the paths derived above.
     2) ~username interpretations will be done at run time rather than

Some versions of Unix support shared libraries, which make executables smaller
but make load time slightly longer.

On some systems, mostly newer Unix System V's, the shared library is included
by putting the option "-lc_s" as the last thing on the cc command line when
linking.  Other systems use shared libraries by default.  There may be other
libraries needed to compile $package on your machine as well.  If your system
needs the "-lc_s" option, include it here.  Include any other special libraries

I can use 'nm' to extract the symbols from your C libraries. This is a time
consuming task which may generate huge output on the disk (up to 3 megabytes)
but that should make the symbols extraction faster. The alternative is to skip
the 'nm' extraction part and to compile a small test program instead to
determine whether each symbol is present. If you have a fast C compiler and/or
if your 'nm' output cannot be parsed, this may be the best solution.

In order to function, CGIwrap issues a library call to change the real 
and effective uid and gid of the current process.

Different systems have different calls available for doing this. 

Your system has the following calls available:

EOM

d_conf_useset='define'

# sete_
if [ "$d_setegid" = "define" ]; then
	echo "   setegid()"
fi

if [ "$d_seteuid" = "define" ]; then
	echo "   seteuid()"
fi

# setre_
if [ "$d_setreuid" = "define" ]; then
	echo "   setreuid()"
fi

if [ "$d_setregid" = "define" ]; then
	echo "   setregid()"
fi

# setres_
if [ "$d_setresuid" = "define" ]; then
	echo "   setresuid()"
fi

if [ "$d_setresgid" = "define" ]; then
	echo "   setresgid()"
fi

# setr_
if [ "$d_setruid" = "define" ]; then
	echo "   setruid()"
fi

if [ "$d_setrgid" = "define" ]; then
	echo "   setrgid()"
fi

# set_
if [ "$d_setuid" = "define" ]; then
	echo "   setuid()"
fi

if [ "$d_setgid" = "define" ]; then
	echo "   setgid()"
fi


$cat <<'EOM'

The CGIwrap source code uses the following logic to determine which
set_ call to use. If this is not correct for your system, or you have 
special needs: 1) Send me a note about it, particularly if it is a 
problem with support for a particular machine. 2) Hand edit the config.sh 
file to change the d_set*id to 'define' and 'undef' as appropriate for the
configuration you desire.

The first match in the following list is used:

	setuid & setgid
	setreuid & setregid
	setresuid & setresgid
	seteuid, setegid, setruid, & setrgid

Regardless of which is chosen, CGIwrap as distributed WILL NOT allow
the script to execute if the both the real and effective uid and gid have 
not been successfully changed to those of the user owning the script. 
This is the case REGARDLESS of what options or setting have been chosen 
in this Configure script.

EOM
