File sharing part 2(Solved)

Postby ajh911 on Wed Apr 24, 2013 4:08 pm

Further to my original post when I believed all resolved now back to square one despite every effort to try and solve the issue myself.
Let me start afresh. I have a new pc (barebones bundle with added 1TB HDD & dvd-RW) so a fresh install of mint 14 with MATE desktop. A netgear wireless router to which the Mint is connected using a wireless aerial adapter (no wireless lan card). My wife has an Asus laptop running Windows 7 connected wirelessly to router. That's the set up.
The Mint is the main PC so has all the working files and stored items. What we want to achieve is the ability for the laptop to access a shared folder on the Mint PC which has all the joint files. So within this shared folder is now the folders and files from the old XP pc that is no longer used. After my original request for help we were able to access, write and save a test file in the shared folder but now all of the folders and files have been added within the shared folder problems have returned.
The laptop can see the Mint PC on the network. It can see the folders & files within the shared folder. Some it can access but they show as read only, the others it comes up with error message saying "cannot access as document name or path is invalid".
If i go to menu/places/network their are two icons one for laptop and the mint and windows network. within windows network is a folder entitled home and within that there are the two computer icons again.
I have created a user for my wife on the Mint using the same name as the login on the laptop ensuring that it is in the same upper lower case way. If you go to administration/shared folders you then see on shared folders tab the path to the shared folder.
I know you will want me to run items etc but please give me step by step instructions and if for Terminal could you give me something I can copy/paste.
Many thanks for any help I just really need to get this sorted and hope i haven't done something to make matters worse.

So far there is absolutely nothing wrong with what you posted. Not sure if sharing the entire home folder of "andy" is a good idea but that's another discussion.

After my original request for help we were able to access, write and save a test file in the shared folder but now all of the folders and files have been added within the shared folder problems have returned.
The laptop can see the Mint PC on the network. It can see the folders & files within the shared folder. Some it can access but they show as read only, the others it comes up with error message saying "cannot access as document name or path is invalid".

All of your shares allow guest access so they will come across as the user "nobody" or if you added your wife to the users on Mint and then added her to the samba database she will come across as "wife" ( for the sake of discussion ).

So let's say Andy creates a file in say ... /home/andy/Shared/Misc/test.txt. It will have permissions of:
-rw-rw-r-- andy andy test.txt

Only andy can read and write to that file. nobody or wife will only be able to read. Is this the problem you are experiencing?

*** If you want nobody and wife to have full access to the file you can either set the files permissions to allow it:
Code: Select all
chmod 0666 /home/andy/Shared/Misc/test.txt

*** Or, you can set this up so that all remote users appear as "andy":
Edit smb.conf as root:
Code: Select all
gksu pluma /etc/samba/smb.conf

And add the following line to the share defintion:
Code: Select all
force user = andy

So that the share definition looks like this:
[Shared]
path = /home/andy/Shared
read only = No
force user = andy
guest ok = Yes

Then save the file and then restart samba:
Code: Select all
sudo service smbd restart

Note: when you restart samba the network has a hissy fit so wait a few minutes before trying to access the share again.

Now when the remote user accesses the share they will be converted to "andy" and have full access to everything "andy" has access to and conversely, when wife or nobody adds a file to the share it will save with owner = andy instead of nobody or wife so andy will have read / write access to those files while within Mint as well.
Please add a [SOLVED] at the end of your original subject header if your question has been answered and solved.

Hi,
You are correct in that I want the laptop/wife to be able open from Mint in laptop, amend and then save to Mint so full access.
Have followed instructions and config is below after adjustment with notice from Terminal following application.
But still no success. Laptop can see but when it opens the file it is read only. Did i enter incorrectly?

# 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 = home

# server string is the equivalent of the NT Description field
server string = %h server (Samba, LinuxMint)

# 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

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

Who owns the specific file that "wife" wants to write to and what are it's permissions?
Code: Select all
ls -l /path/to/specific/file

And by any chance is this a LibreOffice or OpenOffice file?

Further to the previous post. I had re-entered the smb.conf to check that my alterations were still there, which they were. Copied and pasted as above. I had left everything for about 10 mins and still read only. I re-booted the laptop. Still read only. Shut down and started mint still nothing. sat down wrote the above posting. then shutdown the mint pc, put kettle on and came back, thought i would check emails, pressed button it starts up but screen is white and blank!!! Go to laptop, it can see mint pc, can open files AND save!!!. I try to re-boot mint twice but still only get white screen and no HDD activity. SO, turned power off, make the cup of tea, come back start up and hey presto desktop comes back. Check laptop, and life is till good on the file front. Was this the hissy you referred to?!
So to test - shutdown mint and laptop. Finish tea, start mint, then start laptop, now laptop cannot see mint BUT can see and access files which are still ok can still save. If i go menu/places/network no laptop just mint, open windows network and there is icon for mint and laptop. Still no "sight" on laptop although can access files on shared! Then hey presto the laptop suddenly decides it can see the mint pc. Very weird.
SO - it looks like the share issue is solved but may have an issue with way the Network is set up. Any thoughts other than "oh mygod, please go away"

To answer your query it all started life as Word folder documents and been transferred to Mint. Laptop uses Word mint is Libre office (which I am very impressed by).

What is the name and path of the file that is read only to "wife".

Something like /home/andy/Shared/Misc/readonlyfile.txt is what I'm looking for.

I may have confused you. Since mint lost the desktop the laptop can access, read, write and save ALL files on the shared folder.
now desktop on mint is back the laptop can still read, write and save ALL files on the shared folder. It worked - thank you.

it somehow seemed to create an issue with the laptop seeing the Mint but it eventually did of it's own accord but could still access the files even though it couldn't see the Mint!!. that's why i wonder if i might have the network set up incorrectly or is it just another Windows 7 issue?

Every time the samba services are restarted and every time the machine is rebooted Samba and Windows do a little dance together before both can see each other by name. It's a Windows thing and it can take a long time - minutes - many minutes - sometimes 15 minutes or more before things are resolved.

Ironically, In an all Linux or in a Linux / Mac network Samba can be used bypassing this process.
