Can't copy files to Samba server access denied


Ok im using samba 3.028 on ubuntu 8.04.2 with webmin 1.450 GUI. I have the samba set up and can see the share files throughout my network and can log in via the unix passwords I set up. I have given full read right access to these files for the unix users i setup but I still get access denied make sure disk is not write protected when i try to copy files into the shared files. I have tried to copy from a w2k server and w-xp machine.

here is the config file.

[global]
log file = /var/log/samba/log.%m
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
obey pam restrictions = yes
socket options = TCP_NODELAY
write list = user1,user2,shaun
map to guest = bad user
encrypt passwords = yes
passwd program = /usr/bin/passwd %u
passdb backend = tdbsam
dns proxy = no
netbios name = server_name
writeable = yes
server string = server_name
invalid users = root
default = Shared
unix password sync = yes
workgroup = workgroup
os level = 20
valid users = shaun
syslog = 0
panic action = /usr/share/samba/panic-action %d
usershare allow guests = yes
max log size = 1000
pam password change = yes

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field

# 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.

# 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 = true



#### Debugging/Accounting ####

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

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

# 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.

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


####### 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.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.


; guest account = nobody

# 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.

# 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).

# 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'.

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

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

# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no

; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory

# 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

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

# than setting them up individually then you'll need this
; load printers = yes

# printcap file

; printcap name = /etc/printcap

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

I suspect your problem is not samba, but file and directory permissions on the mounted shares.

Open a konsole and look at /media/ and the following nested directories. I think you will find only root has write permissions here; unless you modified them. Here is what it looks like on my system.

Quote:
ll -ad /media/
drwxr-xr-x 5 root root 4096 2009-03-04 09:42 /media/
Note, root is the owner, and group. Only root can write here.

What I have done is mounted the remote shares in my home directory. Here is one entry from my /etc/fstab file.

Quote:
sluggy:/home/cliff/download /home/cliff/sluggy nfs rsize=8192,wsize=8192,nosuid,soft 0 0
The first entry is the remote share, and the second is the mount point on my system.

The permissions...

Quote:
ll -d ~/sluggy
drwxr-xr-x 2 cliff cliff 4096 2007-12-29 14:02 /home/cliff/sluggy/
If I want anyone else to have access, I add them to the 'cliff' group. I can change the Cliff group access, with chown and chmod as required.

Hope this helps...

Unhappy Sorry for being a noob but..

Ok this is my 4th day using linux for the first time. I have used putty to access the server and am in the media directory but dont now how to see the nested directories. I have been pretty dependent on webmin sine i am not good at the CLI yet. From what I can tell in webmin root is the owner. So I need to change the owner to shaun and add the users to my group? If so how do I manage that?

Keep in mind there are permissions for the directories as well as the individual files and these behave somewhat differently.

Can you get a root console from Webmin? On some systems it is permitted.

Did you edit your /etc/fstab file with the changes in directory?

It would help if you posted your /etc/fstab so we can see what is in there.

You need to be root to change users and groups. You can change them in Webmin as well.

To display the directory permissions, you can run the command 'll -ad /home/user/directory' ( enter what is between the quotes ), ll is short for list long; the -ad says all directory. Just edit the /home/user/directory part to match the directory you want to look at. Output should look like this.

Quote:
ll -ad /home/cliff/sluggy
drwxr-xr-x 2 cliff cliff 4096 2007-12-29 14:02 /home/cliff/sluggy/
Note the string of characters on the second line. The d says directory, the rwxr-xr-x shows the permissions for user, group and everyone else. If the letter is there, then it is allowed. A - character in a position says it is not allowed. In this example, group can read and execute in that directory, but not write.

If I want to change it, I can run the chmod command. The easy way is to be the owner of the directory and if I did a 'chmod 777 /home/cliff/sluggy' I would change the permissions on the directory to...

Quote:
chmod 777 /home/cliff/sluggy
cliff@duelie ~/sluggy ll -ad /home/cliff/sluggy
drwxrwxrwx 2 cliff cliff 4096 2007-12-29 14:02 /home/cliff/sluggy/
Now everyone has read write and execute allowed on the files in the directory. Note, the files will have their own permissions, and can be different than the directory.

If you want to change them from a gui interface, you can in Konqueror, providing Konqueror is started as the correct user. On your home directory you don't need to worry about it. If it were a dir, or file in the '/' ( root ) area, then you would need to start Konq as root. That can be done with the command 'kdesu konqueror'. The system will prompt for the root password, give it, then you are running Konq as root. You do need to be careful, you can kill a system if you do the wrong thing.

Got it working.

OK if you are using WEBMIN the easy way to to see who the owner of a file is thru the file manager. So I opened the file manager and located the files I was sharing in samba. I selected the file and hit the info button in webmin's file manager and it showed me who the owner was so i changed the owner and it also allowed me to set the read write perms there. The file manager also allows you to share file too with out having to go through the samba gui.

Result now I can read and write files to these shared folders. Please post if you run into this problem Ill see if I can help. But im still a noob and I don't know the CLI.
