[ale] Cups, Samba, and Qemu...

[Marvin, International Martian of Mystery]

I'm trying to get a machine set-up that runs windows in a full-screen 
instance of Qemu running on a blank X console (no wm), with tun/tap 
networking and ipmasq to talk to the outside world- particularly the 
localhost (via samba), and the HP usb-printer connected to it.

The printer works fine under CUPS in a KDE session.  Test pages come out 
perfectly, and random PDF's downloaded from the interweb come out 
looking like they were printed for the company which produced them by 
pros...

The Virtual Windoze-box has no problem connecting with the wider 
internet, or the LAN gateway.  I can ping, ssh, etc. all over the local 
network- including the localhost.  But SAMBA is giving me problems.  
Sometimes the windoze box can see the local host, but not it's shares, 
sometimes can see shares and host, but can't access 'em anytime.  The 
printer doesn't show up at all.  

<smb.conf>
# 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
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba HOWTO Collection.
#
# 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, eg: LINUX2
workgroup = kdmfam

# server string is the equivalent of the NT Description field
server string = Oscars Goodies

# Security mode. Defines in which mode Samba will operate. Possible
# values are share, user, server, domain and ads. Most people will want
# user level security. See the HOWTO Collection for details.
security = user

# 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 = 192.168.100. 192.168.2. 192.168.1 127.

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
load printers = yes

# you may wish to override the location of the printcap file
;   printcap name = /etc/printcap

# on SystemV system setting printcap name to lpstat should allow
# you to automatically obtain a printer list from the SystemV spool
# system
;   printcap name = lpstat

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

# 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

# Put a capping on the size of the log files (in Kb).
max log size = 50

# 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>

# Use the realm option only with security = ads
# Specifies the Active Directory realm the host is part of
;   realm = MY_REALM

# Backend to store user information in. New installations should
# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.
;   passdb backend = tdbsam

# 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.
# Note: Consider carefully the location in the configuration file of
#       this line.  The included file is read at that point.

# Most people will find that this option gives better performance.
# See the chapter 'Samba performance issues' in the Samba HOWTO Collection
# and the manual pages for details.

#         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.

# 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)

# run a specific logon batch file per username
;   logon script = %U.bat

# Where to store roving profiles (only for Win95 and WinNT)

NOT both

# at least one  WINS Server on the network. The default is NO.

Are there any special considerations for runnning SAMBA over a tun/tap 
network?
