[Samba] Strange access problems with hostname vs ip

Tue Dec 10 15:48:01 GMT 2002

I've recently installed and configured samba 2.2.7 on a Redhat 8.0 box. 
Samba is configured to use share level security and there is a single 
share which is public. When connecting to the machine by IP address 
(\\x.x.x.x\sharename) everything works fine. When I connect by hostname 
(\\hostname\sharename) I get "The account is not authorized to log in from 
this station." Things worth mentioning are that the client machine is a 
member of a domain and is running Windows XP. The samba server has it's 
workgroup set as the name of the domain. It also has a WINS server defined 
and seems to be registering with it correctly. DNS is also not a problem, 
you can ping the machine by hostname without problems. 

Thank you for any help,

Here is my smb.conf:

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

# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = <this is my domain name>

# server string is the equivalent of the NT Description field
   server string = <the machine name>

# 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 = 10.10.150. 10.11.13. 10.11.12.

# 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 = no

# 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 = guest

# 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 = share

# 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 = 

# 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

# The following are needed to allow password changing from Windows to
# update the Linux system 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

# You can use PAM's password change control flag for Samba. If
# enabled, then PAM will be used for password changes when requested
# by an SMB client instead of the program listed in passwd program.
# It should be possible to enable this without changing your passwd
# chat parameter for most setups.

   pam password change = yes

# Unix users can map to different SMB User names

# 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

# Cause this host to announce itself to local subnets here

# 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 = no 

# 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 = no

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

;   logon script = %U.bat

both

# 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.
