go500gw
is the general gopher to X.500 browsing and search gateway daemon.
It speaks gopher on one side and X.500 (via LDAP)
on the other. It presents the X.500 DIT as a tree of menus,
search items, and documents in gopher space, supporting both
browsing and searching of X.500 via a gopher client. By default,
it listens on port 7777 for connections from gopher clients.
The
go500gw
server can be run either from
inetd(8)
or as stand-alone server.
STAND-ALONE OPERATION
To start
go500gw
as a stand-alone server, simply start it with no arguments
/usr/sbin/go500gw
If you would like to start it at boot time add some lines like this to
the
/etc/rc.local(5)
or equivalent file:
if [ -f /usr/sbin/go500gw ]; then
/usr/sbin/go500gw; echo ' go500gw'
fi
OPERATION WITH INETD
To arrange to have
go500gw
started from
inetd(8),theInternetprotocol
daemon, add a line like the following to your
/etc/services(5)
file, or the equivalent:
go500gw 7777/tcp go500gw
Next, add a line like this to your
/etc/inetd.conf(5)
file, or the equivalent:
For these changes to take effect with inetd, you will probably have
to send it it a HUP signal. See
inetd(8)
for more details.
GOPHER CONFIGURATION
The next step is to configure your local gopher server to have an
entry for
go500gw.
With the standard unix gopher server, this
can be done with a
.link
file. 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=1<optional RFC 2253-format DN at which to start browsing>
Host=<host.running.go500gw.here>
You may also have to restart your gopher daemon, or remove the
.cache
file.
OPTIONS
-a
Search aliases when doing LDAP searches. The default is not to
search aliases.
-d level
Turn on debugging as defined by
level.
If this option is specified,
go500gw
will not fork or disassociate from the invoking terminal. Some general
operation and status messages are printed for any value of level.
level is taken as a bit string, with each bit corresponding to a
different kind of debugging information.
-f filterfile
Specify an alternate filter configuration file for use with the
ldap_getfilter(3)
facility, used by
go500gw.
-h helpfile
Specify an alternate help file. The help file is what is displayed
in the "About the Gopher to X.500 Gateway" menu item.
-l
Enable logging of various status and errors to the LOG_DAEMON facility via
syslog(8).
-p listenport
Specify an alternate port on which to listen for connections.
-P ldapport
Specify an alternate port on which to contact the LDAP server.
-t templatefile
Specify an alternate template configuration file for
use with the
ldap_init_templates(3)
facility, used by
go500gw .
-c rdncount
Specify the number of DN components to show for the names and DN attributes
within entries matching the search.
-x hostname
Specify an alternate host on which the ldap server is running.
Some implementations of inetd have a small limit on the number of arguments
that can be specified in the
/etc/inetd.conf(5)
file. This can cause
problems if you are using
go500gw
with a lot of arguments.
The default values for most of the things you can specify with
options are configured at compile time in the
include/ldapconfig.h.edit
include file.
