daft samba problem


Not sure what happened, it has been working just fine. To explain, I have two ubuntu jaunty boxes sat next to one another, and my girlfriends lappy usully via wifi and and win xp box.

So when hell happened I copied the smb.conf frum tux2 to tux, restarted, and checked. Nope, cant find any shares. Out curiosty I logged onto tux2 and asked agine. Now it can find tux, and all is fine, so can lappy.

So it's sorta working, but not from tux.

what is going on ????
Code:
#

# Sample configuration file for the Samba suite for Debian GNU/Linux.

#

#

# 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 most of which 

# are not shown in this example

#

# Some options that are often worth tuning have been included as

# commented-out examples in this file.

#  - When such options are commented with ";", the proposed setting

#    differs from the default Samba behaviour

#  - When commented with "#", the proposed setting is the default

#    behaviour of Samba but the option is considered important

#    enough to be mentioned here

#

# NOTE: Whenever you modify this file you should run the command

# "testparm" to check that you have not made any basic syntactic 

# errors. 

# A well-established practice is to name the original file

# "smb.conf.master" and create the "real" config file with

# testparm -s smb.conf.master >smb.conf

# This minimizes the size of the really used smb.conf file

# which, according to the Samba Team, impacts performance

# However, use this with caution if your smb.conf file contains nested

# "include" statements. See Debian bug #483187 for a case

# where using a master file is not a good idea.

#



#======================= Global Settings =======================



[global]



## Browsing/Identification ###



# Change this to the workgroup/NT-domain name your Samba server will part of

   workgroup = WORKGROUP



# server string is the equivalent of the NT Description field

   server string = %h server (Samba, Ubuntu)



# Windows Internet Name Serving Support Section:

# WINS Support - Tells the NMBD component of Samba to enable its WINS Server

#   wins support = no



# 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



# This will prevent nmbd to search for NetBIOS names through DNS.

   dns proxy = no



# What naming service and in what order should we use to resolve host names

# to IP addresses

;   name resolve order = lmhosts host wins bcast



#### Networking ####



# The specific set of interfaces / networks to bind to

# This can be either the interface name or an IP address/netmask;

# interface names are normally preferred

;   interfaces = 127.0.0.0/8 eth0



# Only bind to the named interfaces and/or networks; you must use the

# 'interfaces' option above to use this.

# It is recommended that you enable this feature if your Samba machine is

# not protected by a firewall or is a firewall itself.  However, this

# option cannot handle dynamic or non-broadcast interfaces correctly.

;   bind interfaces only = yes







#### Debugging/Accounting ####



# This tells Samba to use a separate log file for each machine

# that connects

   log file = /var/log/samba/log.%m



# Cap the size of the individual log files (in KiB).

   max log size = 1000



# If you want Samba to only log through syslog then set the following

# parameter to 'yes'.

#   syslog only = no



# We want Samba to log a minimum amount of information to syslog. Everything

# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log

# through syslog you should set the following parameter to something higher.

   syslog = 0



# Do something sensible when Samba crashes: mail the admin a backtrace

   panic action = /usr/share/samba/panic-action %d





####### Authentication #######



# "security = user" is always a good idea. This will require a Unix account

# in this server for every user accessing the server. See

# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html

# in the samba-doc package for details.

#   security = user



# You may wish to use password encryption.  See the section on

# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

   encrypt passwords = true



# If you are using encrypted passwords, Samba will need to know what

# password database type you are using.  

   passdb backend = tdbsam



   obey pam restrictions = yes



# This boolean parameter controls whether Samba attempts to sync the Unix

# password with the SMB password when the encrypted SMB password in the

# passdb is changed.

   unix password sync = yes



# For Unix password sync to work on a Debian GNU/Linux system, the following

# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for

# sending the correct chat script for the passwd program in Debian Sarge).

   passwd program = /usr/bin/passwd %u

   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .



# This boolean controls whether PAM will be used for password changes

# when requested by an SMB client instead of the program listed in

# 'passwd program'. The default is 'no'.

   pam password change = yes



# This option controls how unsuccessful authentication attempts are mapped 

# to anonymous connections

   map to guest = bad user



########## Domains ###########



# Is this machine able to authenticate users. Both PDC and BDC

# must have this setting enabled. If you are the BDC you must

# change the 'domain master' setting to no

#

;   domain logons = yes

#

# The following setting only takes effect if 'domain logons' is set

# It specifies the location of the user's profile directory

# from the client point of view)

# The following required a [profiles] share to be setup on the

# samba server (see below)

;   logon path = \\%N\profiles\%U

# Another common choice is storing the profile in the user's home directory

# (this is Samba's default)

#   logon path = \\%N\%U\profile



# The following setting only takes effect if 'domain logons' is set

# It specifies the location of a user's home directory (from the client

# point of view)

;   logon drive = H:

#   logon home = \\%N\%U



# The following setting only takes effect if 'domain logons' is set

# It specifies the script to run during logon. The script must be stored

# in the [netlogon] share

# NOTE: Must be store in 'DOS' file format convention

;   logon script = logon.cmd



# This allows Unix users to be created on the domain controller via the SAMR

# RPC pipe.  The example command creates a user account with a disabled Unix

# password; please adapt to your needs

; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u



# This allows machine accounts to be created on the domain controller via the 

# SAMR RPC pipe.  

# The following assumes a "machines" group exists on the system

; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u



# This allows Unix groups to be created on the domain controller via the SAMR

# RPC pipe.  

; add group script = /usr/sbin/addgroup --force-badname %g



########## Printing ##########



# If you want to automatically load your printer list rather

# than setting them up individually then you'll need this

#   load printers = yes



# lpr(ng) printing. You may wish to override the location of the

# printcap file

;   printing = bsd

;   printcap name = /etc/printcap



# CUPS printing.  See also the cupsaddsmb(8) manpage in the

# cupsys-client package.

;   printing = cups

;   printcap name = cups



############ Misc ############



# 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 = /home/samba/etc/smb.conf.%m



# Most people will find that this option gives better performance.

# See smb.conf(5) and /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/speed.html

# for details

# You may want to add the following on a Linux system:

#         SO_RCVBUF=8192 SO_SNDBUF=8192

#   socket options = TCP_NODELAY



# The following parameter is useful only if you have the linpopup package

# installed. The samba maintainer and the linpopup maintainer are

# working to ease installation and configuration of linpopup and samba.

;   message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s; rm %s' &



# Domain Master specifies Samba to be the Domain Master Browser. If this

# machine will be configured as a BDC (a secondary logon server), you

# must set this to 'no'; otherwise, the default behavior is recommended.

#   domain master = auto



# Some defaults for winbind (make sure you're not using the ranges

# for something else.)

;   idmap uid = 10000-20000

;   idmap gid = 10000-20000

;   template shell = /bin/bash



# The following was the default behaviour in sarge,

# but samba upstream reverted the default because it might induce

# performance issues in large organizations.

# See Debian bug #368251 for some of the consequences of *not*

# having this setting and smb.conf(5) for details.

;   winbind enum groups = yes

;   winbind enum users = yes



# Setup usershare options to enable non-root users to share folders

Debug like so...

Check you can ping from one to the other. No ping, no work...

Suppose the two machines are called foo and bah..

foo> ping bah
go to other machine...
bah> ping foo

If that worked. Grreat. If it didn't there's your problem right there. Network does Not Work.

Now look at the output of dmesg and see if you can get some clues. (Paste anything samba related here)

Then
sudo bash
cd /var/log/samba
ls -lrt
and look at anything interesting / juicy there. Paste here so we can help.

Since this is a 'newbie' forum, you might want to explain what 'dmesg' is and how to extract from its output the "anything samba related".

Open up a terminal window and at the prompt type dmesg
myname@mybox:~$ dmesg

It's going to splat a thousand log messages all over your screen. Alas, most of them won't concern samba.

You can either filter out irrelevant jabber. For example my logs have too much cruft relating to fetchmail and usb.

dmesg | grep -viE 'fetchmail|usb'


Or filter it though "less" and explore it on your own.

dmesg | less

Or do both...

dmesg | grep -viE 'fetchmail|usb' | less

Or look for anything directly samba or nmb related.

dmesg | grep -iE 'samba|nmb' | less

Incidentally, that's a useful trick to see what _is_ actually set on in your samba config file less all the comment fluff...

grep -vE '^[:space:]*([#;]|$)' /etc/samba/smb.conf

Even so, that's going at things way too fast for a trubie newbie... so if any newbie didn't follow that (and cares) just ask.

To be fair anm not a true newbie, just a bit stuck on this.

the dmsg thing didn't mention samba or nmb, and the clean smaba..conf is

Hmm. Is all the bits of samba installed on the second machine?

sudo /etc/init.d/samba status
* nmbd is running
* smbd is running

ps auxw | grep -iE '[sn]mb'
root 18556 0.0 0.0 8440 1344 ? Ss Oct19 6:29 /usr/sbin/nmbd -D
root 18559 0.0 0.0 14548 1972 ? Ss Oct19 0:00 /usr/sbin/smbd -D
root 18563 0.0 0.0 14244 432 ? S Oct19 0:00 /usr/sbin/smbd -D

What about /var/log/samba/* any clues / error messages there?

Else it's time just to march through...
http://www.samba.org/samba/docs/man/...diagnosis.html
step by step until you see the problem.

Sigh! Samba is _way_ too configurable and complex in my opinion.

hostnames

I couldn't tell if you were being colorful or if you were trying to do everything with hostnames rather than IP addresses. If that's what you were trying to do, then give it a whirl with the IP addresses. If all goes well that way it's likely host resolution which can be fixed by editing /etc/hosts to include tux and friends.

well till you guys mentioned it, nmb was never running, it is now!

I think that was it, the only problem I have now, is to get onto the win7 (lappy) which is insisting on a password eventhough there isn't one!

Huh? It's just the out of the box config file I thought with the printer cd and a few shares turned on

Were you trying to connect to the server by it's IP address (192.168.x.x) or were you trying to connect by it's hostname (tux, tux2, lappy)? If you were just using the network browse feature then you were doing things by hostname. I've had trouble with linux not being consistent in identifying the hostnames of remote systems. In order to make it 100% accurate I modified the file /etc/hosts. That file maps IP addresses to hostnames a sample would be:
PHP Code:
127.0.0.1    localhost
127.0.1.1    DELL
192.168.1.101    dtest
192.168.1.102    dlin
192.168.1.104    DELL 
That's my /etc/hosts file on this machine.

Try editing `/etc/hosts`. It has ended days of "WTF?!?!?!?!" for me personally.

I use joe so in a terminal I would type:

sudo joe /etc/hosts
MYPASSWORD when prompted

arrow down to the bottom, modify according to the template you'll see for the 127.x.x.x filling in the hostnames. I include all the hosts including the one I'm editing. Hit enter to close the line, save the file (with joe it's ctrl+k+x) and reboot.

You probably don't have joe. vi is default for ubuntu I think. It takes half a second to install with synaptic. it's got a command menu which makes it easy to use for a newbie like me.

It works fine on tux2, and ebassy-pc, print and file sharing the works.

When I click on the network icon on tux, I get windows-networks icon, click on it I get WORKGROUP icon, click on that and unable to mount location, failed to retrive share list from server.

As suggested last night.

well I have just tried using connect to server, and with a few tweaks I can indeed connect to ebassy-pc.

So now its not as important, but why won't it work the usual way?

I bet this line from your log file is a source of woe...

Quote:
can't open username map /etc/samba/smbusers. Error No such file or directory
Don't forget there are two entirely independent notions of identity/authentication/authorization running around. The Windows / Samba username/password/permissions and the Unix/linux username/password/permissions.

smbusers is how the one is mapped to the other.
