  Hi!

    Could you help me about a problem with Jffs Filesystems and
Samba...?

Fitst of all, we are working on a MBX860 board with a MPC860 micro and
our Linux OS is
Hard Hat Linux PPC 2.1. We compiled/configured the Samba 2.2.4 on our
system wihout problem with a gcc 2.96 version...

...we have a folder on a Jffs Filesystem on our second flash partition
(1 MB size and
800 KB free); this folder is shared by our samba daemon and it can be
accesed from any Windows Pc in our Lan... reading a file works fine, but

if you try to copy a file greater than 200KB, Windows File Explorer
shows the following message:

    Cannot create the file FILENAME: Cannot read from the source file...

(This a translation from spanish Windows;-)

    Besides, it is possible to copy several files, from any Windows Pc,
up to 800 KB, but this files have to be smaller than 200 KB size.
    Of course,from console, you can copy a file greater than 200 KB into

that folder without problem...

    Do you any experience in this regard?

    Than you in advance.

    Ciao.

PD: I send you my smb.conf file...

# 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 many any basic syntactic errors.

#======================= Global Settings =====================================
[global]

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

# server string is the equivalent of the NT Description field
   server string = Prodys Pcmcia-Flash File Server 

# 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 = 10. 192.168.1. 127.0.0.1

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

# 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 = prodys 

# this tells Samba to use a separate log file for each machine
# that connects

# 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 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.

;   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 = yes

# 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 = %U.bat

# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
 name resolve order = host lmhosts wins bcast

# 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 = 10.0.0.244

# 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!
