NAME
go500gw - General Gopher to X.500 gateway for browsing and searching
SYNOPSIS
/usr/sbin/go500gw [-a] [-d level] [-f filterfile] [-t templatefile] [-c rdncount] [-h helpfile] [-l] [-p listenport] [-P ldapport] [-x
ldaphost] [-I]
DESCRIPTION
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:
go500gw stream tcp nowait nobody /usr/sbin/go500gw go500gw -I
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 termi-
nal. 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.
-I Run from inetd(8).
NOTES
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.
