Build Your Own Atom-based NAS

[ponq]

Hi, I hope anyone can help me out here, it is driving me crazy. I get permission denied all the time when trying to write something to the nas-share.

I followed the guide and got it all up and running (Ubuntu server 9.04, Webmin, with a RAID 5 config).

I got one share, named NAS.
path /mnt/raidarr

all the permissions etc are set as described in the article.

I can see and view the share on my LAN (another two ubuntu machines, Linux Mint 6 and 7).

However, I cannot copy anything to the share, cannot create a dir from one of the machines (with webmin no prob ofcourse). All the time I get "permission denied".

I have no clue. Any with some tips? Much appreciated!

 

[roamer]

please login into your nas and provide output of the commands:

ls -la /mnt/
cat /etc/samba/smb.conf

Thanks for your reply!

And,

cat /etc/samba/smb.conf



#======================= 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

# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs

Where are the mentioned directory "path /mnt/raidarr" ?

And,

cat /etc/samba/smb.conf

...

Where are the share named "NAS" ?

 

[ponq]

Yeah, that surprises me as well. Could be something went wrong when executing the commands (I asked my wife to do them, b/c I was at work).

Here's the (correct?) output:

ls -la /mnt/
total 12
drwxr-xr-x 3 root root 4096 2009-05-27 01:02 .
drwxr-xr-x 21 root root 4096 2009-05-27 06:26 ..
drwxr-xr-x 3 root root 4096 2009-05-27 01:00 raidarr


And the smb.conf section regarding the NAS:

[NAS]
comment = Onze NAS
writeable = yes
guest only = yes
public = yes
path = /mnt/raidarr
available = yes


Any better?

login into your nas and execute the following command:

sudo chmod -R 777 /mnt/raidarr


currently only root has write permission to /mnt/raidarr.

thanks buddy! That did the trick!

Thank you Tim. I just built a MSI Wind Nettop 100 with Ubuntu Server 9.04 following these excellent instructions. I installed the OS to a 4Gb CF (without a swap file) and have RAID 1 across 2 1Tb WD Green drives. This will be replacing a couple of aging NSLU2 units. Again thank you.

Thank you Tim. I just built a MSI Wind Nettop 100 with Ubuntu Server 9.04 following these excellent instructions....

Glad to help.

Had been thinking about a synology or QNAP but looking at an ATOM self build looks to be a cost effective option.

The MSI Wind sounds like a good option rather than buying board/case seperate. My trouble is finding it in the UK.

Has anyone been able to get hold of one in the UK - importing from the US would be OK except trying to find someone who will ship and also not charge as much as the Wind itself appears to be next to impossible...

Have a look at the BBS2 model here (http://www.tranquilpc-shop.co.uk/) its pretty competitive with price of a self-build. I just got one myself.

And if you only need one drive, then their T7 barebones model is even cheaper and totally silent. You cant build anything like that yourself for less than 2x or 3x their price.

Wind PC using CF - how is the performance

I have installed Ubuntu 8.10 on a windpic on a single 1tb wd hard disk.
I also installed XMBC and am able to view videos on my large screen tv.
I am not getting the NAS performance quoted at this site but still pretty good.

Q. I was wondering how well it works when installed on a CF card. Is the performance
comparable to HD install assuming that the swap is still on the HD.
Further, with periodic access-time updates do the CF cards last?

A couple of pages back there was a question of whether Windows Home Server would work on an Atom, the answer is yes. Unluckily, the reports of using this as a media streamer have been negative, the demigrator issue seems to cause difficulties ( stuttering ).
