Yes, I've managed to successfully build a YP auto.master map. We used it
for about 3 months, and it seems to work smoothly so far. Our YP clients
don't hang indefinitely at login time, though sometime they did hang 1 or
2 minutes (rarely happened).

There are two automount data base files, auto.master and auto.w100, in our
configuration. The difference between our configuration and yours is that
we use inderect map instead of direct map.

# auto.master
#
# DIRECTORY     MAP             MOUNT OPTIONS
/net            -hosts          -intr
/w100           /etc/auto.w100  -intr

# auto.w100 (partial listing)
#
ssh             x2mips1:/usr/src/srcdsk1/export/x2sun3/ssh

The following is my makefile for making YP automounter database. It's
modified from the YP makefile of one Sun 386i machine.

# Makefile for making YP auto.master
#                        auto.w100
#
DIR =/etc
DOM = `domainname`
NOPUSH = ""
YPDIR=/usr/etc/yp
YPDBDIR=/var/yp
YPPUSH=$(YPDIR)/yppush
MAKEDBM=$(YPDIR)/makedbm

ALL_TARGETS = \
        auto.master \
        auto.w100

all: $(ALL_TARGETS)

auto.master: auto.master.time
auto.w100: auto.w100.time

auto.master.time: $(DIR)/auto.master
auto.w100.time: $(DIR)/auto.w100

auto.master.time \
auto.w100.time:
        - at if [ -f $(DIR)/$(@:.time=) ]; then \
                sed -e '/^[      ]*#/d' $(DIR)/$(@:.time=) \
                        | $(MAKEDBM) - $(YPDBDIR)/$(DOM)/$(@:.time=); \
                touch $@; \
                echo "updated $(@:.time=)"; \
                if [ ! $(NOPUSH) ]; then \
                        $(YPPUSH) $(@:.time=); \
                        echo "pushed $(@:.time=)"; \
                else \
                        : ; \
                fi \
        else \
                echo "couldn't find $(DIR)/$(@:.time=)"; \
        fi


  Our starting procedure of automounter at YP server and YP client are
different.

# at YP server
#
if [ -f /usr/etc/automount ]; then
        automount -f /etc/auto.master&  (echo -n ' automount')  >/dev/console
fi

# at YP client
#
if [ -f /usr/etc/automount ]; then
        automount &             (echo -n ' automount')  >/dev/console
fi


  The above is our automount configuration, hope it will give you some help.


Though our automounter runs smoothly, I have another question about YP
automount database. I have made both auto.master and auto.w100 into YP
database, but our YP clients can't access YP auto.w100, they can only use
YP auto.master. So I had to copy auto.w100 into all machines, either YP
server or YP clients should contain a local /etc/auto.w100 file to keep
our YP automounter running correctly. According to Sun's manual page, I
had tried to modify auto.master file as follows:

# auto.master
#
# DIRECTORY     MAP             MOUNT OPTIONS
/net            -hosts          -intr
/w100           +auto.w100      -intr

But it still doesn't work.  Could someone out there tell me how to make
automount database so that I can save much of SA work of making copies of
auto.w100, auto.w200, ...

Thanks in advance.

PS. I agree with davis that Sun's automounter manual is not well written.
We need more examples about how to use automounter on YP.
