samba4 not working

[DrRob]

Hi,

I'm trying to set up samba4 server, but it's not working.  Here are my steps:

• Download and flash piCore-9.0.3 to an SD card
• Transfer SD card to Pi (an original model B) and boot
• Find out the IP address of the Pi
• ssh to the pi (user: tc, password: piCore)
• resize the second partition (see the README)
• filetool.sh -b (to save the generated ssh host key)
• sudo reboot (so the kernel can see the enlarged partition)
• ssh in again
• resize the filesystem (see the README)
• add "mount /mnt/sda1" to /opt/bootlocal.sh (the files I want to share are on a USB memory stick)
• mount /mnt/sda1
• tce-load -wi samba4
• install my smb.conf to /usr/local/etc/samba (it makes a directory from /mnt/sda1 available via a share)
• add /usr/local/etc/samba to /opt/.filetool.lst
• sudo adduser and sudo smbpasswd -a for a couple of users that are referenced in the smb.conf
• filetool.sh -b (to save the setup so far)
• sudo reboot (just in case...)
• how are you supposed to set up the samba service to run automatically?  For now I'm running it manually, with debugging on...
• sudo smbd -i -d20
• ...results in lots of debug, ending with "waiting for connections".  So far, so good.
• Attempt to connect to the share from a Macbook, using the IP address of the Pi
• A pause of a couple of seconds, then more debug output from samba, ending with "Server exit (failed to receive smb request)" and "Terminated" twice.  :-(

I'll attach a gzip'd file containing the debug output.

What am I doing wrong?

Thanks,
Rob.

Code: [Select]

sudo /usr/local/etc/init.d/samba start


[DrRob]

/usr/local/etc/init.d/samba doesn't exist...

[Misalf]

Oh, you're right. I modified my copy to include that script.
What it basically does is

Code: [Select]

mkdir -p /var/lib/samba
mkdir -p /usr/local/etc/samba/private
/usr/local/sbin/nmbd -D
/usr/local/sbin/smbd -D


[DrRob]

Thanks for that, but unfortunately smbd still crashes when I try to open the share.  :-( 

(nmbd is fine.)

[DrRob]

Ah, ok, apparently that's normal when running "smbd -i": https://lists.samba.org/archive/samba/2012-September/169099.html (which makes that mode kinda useless...).

Now I see a different error in /usr/local/var/log/samba/smbd.log:

  check_ntlm_password:  Authentication for user [recorder] -> [recorder] FAILED with error NT_STATUS_NO_SUCH_USER

so that's progress.

[Paul_123]

You have to create the samba user/password files.

smbpasswd -s -a tc

This will create everything needed for authentication..... the files are saved in /usr/local/var/lib/samba so be sure you add these to you backups.

I believe that the user name you use above has to be a username on the piCore system.

[DrRob]

Thanks Misalf and Paul_123, I have it working now.  Tomorrow I'll post the working bullet-list of steps in case anyone else needs to do this.

So, here's a verified list of steps to set up piCore as a Samba server:

• Download and flash piCore-9.0.3 to an SD card
• Transfer SD card to Pi (an original model B) and boot
• Find out the IP address of the Pi
• ssh to the pi (user: tc, password: piCore)
• resize the second partition (see the README)
• filetool.sh -b (to save the generated ssh host key)
• sudo reboot (so the kernel can see the enlarged partition)
• ssh in again
• resize the filesystem (see the README)
• add "mount /mnt/sda1" to /opt/bootlocal.sh (the files I want to share are on a USB memory stick)
• mount /mnt/sda1
• tce-load -wi samba4
• install my smb.conf to /usr/local/etc/samba (it makes a directory from /mnt/sda1 available via a share)
• add the following to /opt/.filetool.lst:

Code: [Select]

/usr/local/etc/samba
/usr/local/etc/init.d/samba
/usr/local/var/lib/samba

• sudo adduser and sudo smbpasswd -a for a couple of users that are referenced in the smb.conf (I see some output from smbpasswd on the first run that looks like errors, but it seems to be ok)
• create file /usr/local/etc/init.d/samba containing:

Code: [Select]

mkdir -p /var/lib/samba
mkdir -p /var/log/samba
mkdir -p /usr/local/etc/samba/private
/usr/local/sbin/nmbd -D
/usr/local/sbin/smbd -D


• sudo chmod +x /usr/local/etc/init.d/samba
• add to the end of /opt/bootlocal.sh:

Code: [Select]

/usr/local/etc/init.d/samba start

• filetool.sh -b
• sudo reboot
• The network share should be available now, by IP address or by share name

[Misalf]

Code: [Select]

/usr/local/etc/init.d/samba start
If the script you created (/usr/local/etc/init.d/samba) doesn't use any arguments, the  start  option can (or should?) be omitted.

[DrRob]

True, it's a very minimalistic version of the init script.

I'm wondering if there's a package containing a service management tool that would look after starting up samba and restarting it if it dies.  Something to add to the to-do list...

So, here's a verified list of steps to set up piCore as a Samba server:

• install my smb.conf to /usr/local/etc/samba (it makes a directory from /mnt/sda1 available via a share)

Where do we find your smb.conf example?

[njs]

Also, I cannot seem to even create an smb.conf.  Even using "sudo" I get "-sh: can't create sbm.conf: Permission denied"

[DrRob]

Where do we find your smb.conf example?

SMB configuration is a bit out of scope of this discussion, but see the attached example.  Note that I have a USB stick plugged into the Pi with a "recordings" directory at its root, so the "path = /mnt/sda1/recordings" in this smb.conf is valid, and I've created a couple of users to match those quoted in smb.conf.

HTH,
Rob.

[DrRob]

Also, I cannot seem to even create an smb.conf.  Even using "sudo" I get "-sh: can't create sbm.conf: Permission denied"

Please post the command-line you're trying.
