openldap/clients/gopher

This directory contains source for two programs:

	go500		A gopher index search server to X.500 gateway

	go500gw		A more general gopher to X.500 gateway

Both programs use the LDAP protocol to talk to X.500.

What you are trying to set up looks like this:

 --------             -----------------            --------           --------
| gopher |           | gopher to| LDAP |          | LDAP   |         | X.500  |
| client |<- gophr ->| LDAP g/w | API  |<- LDAP ->| server |<- DAP ->| server |
|________|           |__________|______|          |________|         |________|
                       go500gw                      ldapd
                         or
                        go500

Both go500 and go500gw can be run either from inetd or as stand-alone
servers.

go500 is useful when you always want to search a fixed portion of the X.500
tree.  It does not let you browse around or change where you search.

go500gw is useful when you want to provide a more general and flexible
gateway from gopher to X.500.  It allows users to browse around anywhere
in the X.500 tree, doing searches at any point.

*                            RUNNING go500                                *
**************************************************************************

1) Make and install the ldap distribution if you have not already done so:

	(cd ../; make lib-only; make inst-lib)

   or

	(cd ../; make all; make install)

   Use the second form if you don't already have an ldapd running
   somewhere you can connect to.  Note that to make an ldap server,
   you will need the ISODE libraries and include files.

2) Tailor go500 to your site before compiling:

	vi go500.c

   There are a couple of things to change in go500.c:

	DAPUSER - This is the DN go500 will bind to the directory as.
		You can specify NULL if you want.

	DEFAULT_BASE - This is the DN of the object below which go500
		will conduct its search.  You typically want this to
		be the DN or your organization.

	DEFAULT_LDAPHOST - This is the host that is running the ldap
		server.  If it's not on the localhost, you'll need to
		change this.

3) Make go500:

	make

4) Start the ldap daemon:

	ldapd [-c dsaname]

   You only need to do this if you're not already running one.

5) Start go500 as a stand-alone server:

	go500

   or arrange to have it start from inetd:

	# vi /etc/services	/* add the following line */
	go500           5555/tcp        go500           # go500 server

	# vi /etc/inetd.conf	/* add the following line */
	go500   stream  tcp     nowait  nobody  $(ETCDIR)/go500    go500 -I

	# kill -HUP <inetdpid>	/* make inetd notice the change */

   where $(ETCDIR) is replaced by the ETCDIR from the top level Makefile
   and <inetdpid> is replaced by the pid of the inetd process.

6) Configure your local gopher server to have an entry for go500.
   A sample .link file is given below, with the things you should
   change given in <>'s:

	Name=<Label of your choice>
	Type=7
	Port=5555
	Path=
	Host=<host.running.go500.here>

   You may also have to restart your gopher daemon, or remove
   the .cache file.

7) Run a gopher client and try it out.

**************************************************************************

1) Make the ldap distribution if you have not already done so:

	(cd ../; make lib-only)

   or

	(cd ../; make lib-only ldap-server)

   Use the second form if you don't already have an ldapd running
   somewhere you can connect to.  Note that to make an ldap server,
   you will need the ISODE libraries and include files.

2) Tailor go500gw to your site before compiling:

	vi go500gw.c

   There are a couple of things to change in go500gw.c:

	GO500DN - This is the DN go500gw will bind to the directory as.
		You can specify NULL if you want.

	HELPFILE - This is the pathname of the helpfile (actually, the
		file that's displayed when a user chooses "About the
		Gopher to X.500 Gateway").

	LDAPHOST - This is the host that is running the ldap server.
		If it's not on the localhost, you'll need to change this.

3) Make go500gw:

	make

4) Start the ldap daemon:

	ldapd [-c dsaname]

   You only need to do this if you're not already running one.

5) Start go500gw either as a stand-alone server:

	go500gw

   or arrange to have it start from inetd:

	# vi /etc/services	/* add the following line */
	go500gw           5555/tcp        go500gw           # go500gw server

	# vi /etc/inetd.conf	/* add the following line */
	go500gw	stream	tcp	nowait	nobody	$(ETCDIR)/go500gw  go500gw -I

	# kill -HUP <inetdpid>	/* make inetd notice the change */

   where $(ETCDIR) is replaced by the ETCDIR from the top level Makefile
   and <inetdpid> is replaced by the pid of the inetd process.

6) Configure your local gopher server to have an entry for go500gw.
   A sample .link file is given below, with the things you should
   change given in <>'s:

	Name=<Label of your choice>
	Type=1
	Port=7777
	Path=M
	Host=<host.running.go500gw.here>

   You may also have to restart your gopher daemon, or remove
   the .cache file.

   If you want to start go500gw at some point in the X.500 tree
   other than the root, you can change the Path parameter above
   to something like this, for example:

	Path=Mo=University of Michigan,c=US

   Of course, you would substitute your own organization's DN.

7) Run a gopher client and try it out.
