[Samba] Problem doing a simple automount via Samba...

[Kirt Dankmyer]

I've looked at documenation, I've gone over mailing list archives,
I've checked various FAQs. I'm sure I'm missing something simple.

I've got two RedHat (Red Hat Enterprise Linux WS release 3) boxes,
devfront and devback. I'm trying to set up an automount so that I can
automatically mount a share from devback on devfront.

On devfront, here is /etc/auto.master:

# $Id: auto.master,v 1.2 1997/10/06 21:52:03 hpa Exp $
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
/misc	/etc/auto.misc	--timeout=60

Also on devfront, here is /etc/auto.misc:

# $Id: auto.misc,v 1.2 1997/10/06 21:52:04 hpa Exp $
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# Details may be found in the autofs(5) manpage

cd		-fstype=iso9660,ro,nosuid,nodev	:/dev/cdrom

# the following entries are samples to pique your imagination
#linux		-ro,soft,intr		ftp.example.org:/pub/linux
#boot		-fstype=ext2		:/dev/hda1
#floppy		-fstype=auto		:/dev/fd0
#floppy		-fstype=ext2		:/dev/fd0
#e2floppy	-fstype=ext2		:/dev/fd0
#jaz		-fstype=ext2		:/dev/sdc1
#removable	-fstype=ext2		:/dev/hdd
rh	-ro,soft,intr           inet640.aamc.org:/mirror/rh
ks	-ro,soft,intr		inet640.aamc.org:/kickstart
sharedcache -fstype=smbfs,ro,port=445,credentials=/etc/devback.creds
://devback/shared

The directory I'm concerned about is sharedcache. Here's the
/etc/samba/smb.conf from devback:

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#======================= Global Settings =====================================
[global]

# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = devback Cluster

# server string is the equivalent of the NT Description field
   server string = devback
   netbios name = devback

# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
   hosts allow = 143.220. 10.


# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this
#   printcap name = /etc/printcap
#   load printers = yes

# It should not be necessary to spell out the print system type unless
# yours is non-standard. Currently supported print systems include:
# bsd, sysv, plp, lprng, aix, hpux, qnx
#   printing = lprng

# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used
;  guest account = pcguest

# this tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/%m.log

# Put a capping on the size of the log files (in Kb).
   max log size = 0

# Security mode. Most people will want user level security. See
# security_level.txt for details.
   security = user

# Use password server option only with security = server
# The argument list may include:
#   password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
# or to auto-locate the domain controller/s
#   password server = *
;   password server = <NT-Server-Name>

# Password Level allows matching of _n_ characters of the password for
# all combinations of upper and lower case.
;  password level = 8
;  username level = 8

# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
   encrypt passwords = yes
   smb passwd file = /etc/samba/smbpasswd

# The following is needed to keep smbclient from spouting spurious errors
# when Samba is built with support for SSL.
;   ssl CA certFile = /usr/share/ssl/certs/ca-bundle.crt

# The following are needed to allow password changing from Windows to
# update the Linux sytsem password also.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
#        the encrypted SMB passwords. They allow the Unix password
#        to be kept in sync with the SMB password.
;  unix password sync = Yes
;  passwd program = /usr/bin/passwd %u
;  passwd chat = *New*password* %n\n *Retype*new*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully*

# Unix users can map to different SMB User names
#  username map = /etc/samba/smbusers

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting
;   include = /etc/samba/smb.conf.%m

# This parameter will control whether or not Samba should obey PAM's
# account and session management directives. The default behavior is
# to use PAM for clear text authentication only and to ignore any
# account or session management. Note that Samba always ignores PAM
# for authentication in the case of encrypt passwords = yes

;  obey pam restrictions = yes

# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

# Configure Samba to use multiple interfaces
# If you have multiple network interfaces then you must list them
# here. See the man page for details.
;   interfaces = 192.168.12.2/24 192.168.13.2/24
#interfaces = 143.220.3.0/24

# Configure remote browse list synchronisation here
#  request announcement to, or browse list sync from:
#	a specific host or from / to a whole subnet (see below)
;   remote browse sync = 192.168.3.25 192.168.5.255
# Cause this host to announce itself to local subnets here
;   remote announce = 192.168.1.255 192.168.2.44

# Browser Control Options:
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply
;   local master = no

# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
;   os level = 33

# Domain Master specifies Samba to be the Domain Master Browser. This
# allows Samba to collate browse lists between subnets. Don't use this
# if you already have a Windows NT domain controller doing this job
;   domain master = yes

# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election
;   preferred master = yes

# Enable this if you want Samba to be a domain logon server for
# Windows95 workstations.
;   domain logons = yes

# if you enable domain logons then you may want a per-machine or
# per user logon script
# run a specific logon batch file per workstation (machine)
;   logon script = %m.bat
# run a specific logon batch file per username
;   logon script = %U.bat

# Where to store roving profiles (only for Win95 and WinNT)
#        %L substitutes for this servers netbios name, %U is username
#        You must uncomment the [Profiles] share below
;   logon path = \\%L\Profiles\%U

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
;   wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
#	Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one	WINS Server on the network. The default is NO.
;   wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
   dns proxy = no

# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis
;  preserve case = no
;  short preserve case = no
# Default case is normally upper case for all DOS files
;  default case = lower
# Be very careful with case sensitivity - it can break things!
;  case sensitive = no

#============================ Share Definitions ==============================
#[homes]
#   comment = Home Directories
#   browseable = no
#   writable = yes
#   valid users = %S
#   create mode = 0664
#   directory mode = 0775
# If you want users samba doesn't recognize to be mapped to a guest user
; map to guest = bad user


# Un-comment the following and create the netlogon directory for Domain Logons
; [netlogon]
;   comment = Network Logon Service
;   path = /usr/local/samba/lib/netlogon
;   guest ok = yes
;   writable = no
;   share modes = no


# The following two entries demonstrate how to share a directory so that two
# users can place files there that will be owned by the specific users. In this
# setup, the directory should be writable by both users and should have the
# sticky bit set on it to prevent abuse. Obviously this could be extended to
# as many users as required.

[shared]
   comment = data share
   path = /data1/shared
   valid users = cfusionid cfusiondev credtest
   force group = shared
   public = no
   writable = yes
   printable = no
   create mask = 0765

Okay, so, here's what happens if I try to make use of the directory on
devfront, plus a tail of the messages log so you can see the error I'm
getting:

[root at devfront root]# cd /misc
[root at devfront misc]# cd sharedcache
-bash: cd: sharedcache: No such file or directory
[root at devfront misc]# tail /var/log/messages

Jan 30 12:32:18 devfront automount[21917]: failed to mount /misc/sharedcache
[root at devfront misc]#

I'm not sure why I'm getting these errors; the /etc/devback.creds file
on devfront contains the username and password for credtest on
devback, which is one of the accounts that has access to the share.
What am I doing wrong here?

This is the version of samba I'm using:

[root at devfront misc]# rpm -qa | grep samba
samba-common-3.0.9-1.3E.2
samba-3.0.9-1.3E.2
samba-client-3.0.9-1.3E.2
[root at devfront misc]# cat /etc/redhat-release
Red Hat Enterprise Linux WS release 3 (Taroon Update 4)

[kdankmyer at devback kdankmyer]$ rpm -qa | grep samba
samba-common-3.0.9-1.3E.3
samba-client-3.0.9-1.3E.3
samba-3.0.9-1.3E.3
[kdankmyer at devback kdankmyer]$ cat /etc/redhat-release
Red Hat Enterprise Linux WS release 3 (Taroon Update 5)

Could the version mismatch be the problem? E.2 as opposed to E.3? It
seems like it would make so little difference...
