go500 - Local Gopher index search to X.500 search gateway
/usr/sbin/go500 [-b searchbase] [-d level] [-l] [-x hostname] [-c
rdncount] [-f filterfile] [-t templatefile] [-p port] [-I]
go500 is the local gopher index search to X.500 search daemon. It
looks like a gopher index server to a gopher client, translating the
search criteria it is given into a search of a pre-configured portion
of the X.500 directory. It uses LDAP to talk to X.500. By default, it
listens on port 5555 for connections from gopher clients.
The go500 server can be run either from inetd(8) or as stand-alone
To start go500 as a stand-alone server, simply start it with no argu-
If you would like to start it at boot time add some lines like this to
the etc/rc.local or equivalent file:
if [ -f /usr/sbin/go500 ]; then
/usr/sbin/go500; echo ' go500'
OPERATION WITH INETD
To arrange to have go500 started from inetd(8), the Internet protocol
daemon, add a line like the following to your /etc/services file, or
go500 5555/tcp go500
Next, add a line like this to your /etc/inetd.conf file, or the equiva-
go500 stream tcp nowait nobody /usr/sbin/go500 go500 -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.
The next step is to configure your local gopher server to have an entry
for go500. 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>
You may also have to restart your gopher daemon, or remove the .cache
file. See gopherd(8) for more details.
Specify an alternate starting point for searches. The argument
should be a Distinguished Name in the form defined by RFC 1485.
For example, the DN "o=University of Michigan, c=US" could be
given to search the University of Michigan portion of the X.500
Turn on debugging as defined by level. If this option is speci-
fied, go500 will not fork or disassociate from the invoking ter-
minal. 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 informa-
Specify an alternate filter configuration file for use with the
ldap_getfilter(3) facility, used by go500.
-l Enable logging of various status and errors to the LOG_DAEMON
facility via syslog(8).
Specify an alternate port on which to listen for connections.
Specify an alternate template configuration file for use
with the ldap_init_templates(3) facility, used by go500.
Specify the number of DN components to show for the names and DN
attributes within entries matching the search.
Specify an alternate host on which the ldap server is running.
-I Run from inetd(8).
Some implementations of inetd have a small limit on the number of argu-
ments that can be specified in the /etc/inetd.conf(5) file. This can
cause problems if you are using go500 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
ldap(3), inetd(8), gopherd(8), go500gw(8)
