samba - Mar 2015 - Windows XP sees fedora14/samba3 shares but not fedora20/samba4 shares

Marc, et al,

Thanks for your reply.  Sorry, I didn't mean to be confusing.

Summary of problem:
  1) XP sees samba shares on fedora14/samba3 machine, but not on
fedora20/samba4 machines.
  2) all fedora machines see all shares including on XP machine.
  3) clicking on f20 machine from XP tries to log in rather than showing
the shares. Login is not successful.
  4) all machines can ping each other by name.

Attached files:
  my-f14-smb.conf (comments stripped off)
  my-f20-smb.conf (comments stripped off)   <--- XP cannot see shares
  default-f20-smb.conf

  f20-samba-logs (log.nmbd, smbd, lap3 on f20 machine
  f14-samba-logs   --"-- on f14 machine

Hope this is clearer.
Thanks.

	-Al

# This is the main Samba configuration file. For detailed information about the
# options listed here, refer to the smb.conf(5) manual page. Samba has a huge
# number of configurable options, most of which are not shown in this example.
#
# The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step
# guides for installing, configuring, and using Samba:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# The Samba-3 by Example guide has working examples for smb.conf. This guide is
# generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# In this file, lines starting with a semicolon (;) or a hash (#) are
# comments and are ignored. This file uses hashes to denote commentary and
# semicolons for parts of the file you may wish to configure.
#
# Note: Run the "testparm" command after modifying this file to check
for basic
# syntax errors.
#
#---------------
# Security-Enhanced Linux (SELinux) Notes:
#
# Turn the samba_domain_controller Boolean on to allow Samba to use the useradd
# and groupadd family of binaries. Run the following command as the root user to
# turn this Boolean on:
# setsebool -P samba_domain_controller on
#
# Turn the samba_enable_home_dirs Boolean on if you want to share home
# directories via Samba. Run the following command as the root user to turn this
# Boolean on:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory, such as a new top-level directory, label it
# with samba_share_t so that SELinux allows Samba to read and write to it. Do
# not label system directories, such as /etc/ and /home/, with samba_share_t, as
# such directories should already have an SELinux label.
#
# Run the "ls -ldZ /path/to/directory" command to view the current
SELinux
# label for a given directory.
#
# Set SELinux labels only on files and directories you have created. Use the
# chcon command to temporarily change a label:
# chcon -t samba_share_t /path/to/directory
#
# Changes made via chcon are lost when the file system is relabeled or commands
# such as restorecon are run.
#
# Use the samba_export_all_ro or samba_export_all_rw Boolean to share system
# directories. To share such directories and only allow read-only permissions:
# setsebool -P samba_export_all_ro on
# To share such directories and allow read and write permissions:
# setsebool -P samba_export_all_rw on
#
# To run scripts (preexec/root prexec/print command/...), copy them to the
# /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.
# Note that if you move the scripts to /var/lib/samba/scripts/, they retain
# their existing SELinux labels, which may be labels that SELinux does not allow
# smbd to run. Copying the scripts will result in the correct SELinux labels.
# Run the "restorecon -R -v /var/lib/samba/scripts" command as the
root user to
# apply the correct SELinux labels to these files.

# server.

# system.
#
# load printers = when set you yes, the list of printers is automatically
# loaded, rather than setting them up individually.
#

#
# The options in this section can be un-commented if the file system supports
# extended attributes, and those attributes are enabled (usually via the
# "user_xattr" mount option). These options allow the administrator to
specify
# that DOS attributes are stored in extended attributes and also make sure that

IT WORKED!!!  THANK YOU.
Now the XP machine can see both the f14 and f20 shares.  (It was not
even necessary to restart nmbd or smbd on the f20 machines.)

Now, if I'm not asking for too much, can you please explain why this
worked.  :-)

Many thanks again.
