how to use automounter with thumbdrive

[Database Administrator]

I've been mounting my thumb drives by hand and would like to use the
automounter to do this, both for convenience and also so that I learn how
to use the automounter. The usually execellent Handbook has failed to help
- it basically just points to the man pages for amd(8) and amd.conf(5), and
these in turn have proved to be totally opaque to me. Can anyone give me
clear directions on how to automount a thumb drive? I currently have
labelled the thumb drive and added an entry in /etc/fstab that allows me
mount the drive manually:

/dev/label/mtd /mtd msdosfs rw,noauto,-M775,-m664,-l

I know that I have to enable the automounter in /etc/rc.conf:

amd_enable="YES"

I am completely mystified about what has to be in /etc/amd.conf and
/etc/amd.map to get this to work.

(And, yes, I *have* googled, and the few examples of how to supposedly do
this are either out of date or otherwise have failed to provide an answer.)

Hi Will,

Here is my configuration, which is working (for me ):

/etc/amd.conf:
[ global ]
restart_mounts = yes
unmount_on_exit= yes

/etc/amd.map:
flash type:=program;fs:=/mnt/flash;\
mount:="/sbin/mount mount /mnt/flash";\
unmount:="/sbin/umount umount /mnt/flash"

/etc/fstab:
/dev/label/tdk /mnt/flash msdosfs rw,noauto 0 0

/etc/rc.conf:
portmap_enable=YES
portmap_flags="-h 127.0.0.1"
amd_enable=YES
amd_flags="-a /.amd_mnt -c 10 -w 2 -l syslog /media /etc/amd.map"

I used the examples from the amd manual:
http://www.am-utils.org/docs/am-util...16.html#SEC279

and this guide:

Thanks for the reply, but it still doesn't work for me. I modified my
amd.conf, amd.map, fstab, and rc.conf to exactly match yours, with the
single exception of the entry in fstab where I use my disk label:

/dev/label/mtd /mnt/flash msdosfs rw,noauto,-M775,-m664,-l

But still no joy...

Hi Will,

Does /mnt/flash exist? Are amd and portmap running? Any relevant log output?
Does the 'mount /mnt/flash' work?

$ ps -ax | grep 'amd\|rpc'
700 ?? Is 0:00.04 /usr/sbin/rpcbind
702 ?? Ss 0:00.15 /usr/sbin/amd -p -a /.amd_mnt -c 10 -w 2 -l syslog \
/media /etc/amd.map

Yes, I created /mnt/flash and can mount it manually without problem. Both
amd and rpcbind are running. There are no messages from amd of any kind in
/var/log/messages. (Incidentally, although I added the portmap entries to
/etc/rc.conf just as you have, I think they may not do anything. It looks
like portmap was renamed to rpcbind at some point in the past, but I
already had rpcbind_enable="YES" in my /etc/rc.conf because I'm using NFS.)

I think you are right about portmap becoming rpcbind. I've changed rc.conf
to use rpcbind_enable and rpcbind_flags -- this works on my system.

You can turn on debugging by adding "-D all" to amd_flags in rc.conf.

No difference - the log file still shows no messages. I've been
re-studying the man pages for amd(8) and amd.conf(5), but nowhere do they
explain exactly what a "map" is or its format. It's very frustrating.

I used the web manual for am-utils[1] as a reference for amd.map. While
reviewing amd(8) I noticed amq(8), which is the automounter query tool.
It'd be interesting to see what this returns on your system.

I've been playing around with the configuration and now have the following:

In /etc/fstab:

/dev/label/mtd /mtd msdosfs rw,noauto,-M775,-m664,-l

In /etc/amd.conf:

[ global ]
restart_mounts = yes
unmount_on_exit= yes

[ /mtd ]
map_name = amd.map

In /etc/amd.map:

mtd type:=program;fs:=/mtd;\
mount:="/sbin/mount mount /mtd";\
unmount:="/sbin/umount umount /mtd"

In /etc/rc.conf:

amd_enable="YES"
amd_flags="-c 10 -w 2 -l syslog:local0 /mtd /etc/amd.map"

(I discovered that if I explicitly specify a syslog level as above, I do
get messages logged, as shown below.)

Output of amq:
/ root "root" nephthyspid1018)
/mtd toplvl /etc/amd.map /mtd

Log entries in /var/log/local0 (timestamps edited out to save space):
