Installing Samba [SOLVED]

[hengreer]

Hi all, relatively new to the raspberry pi. Using version 3b.
I'm trying to set up a plex server on the pi, I've got the server up and running and I now just need to put things on it. To do this I wanted to share a folder on a HDD mounted to the pi to be able to transfer files from my windows pc to the pi without having to unplug the HDD. I've got it mounted I believe and am trying to install samba.

I ran this

Code: Select all

$ sudo apt-get install samba samba-common-bin

It ran fine until I came upon the problem below. (This is the same errors just from an apt upgrade)

Code: Select all

Anyone have any ideas how to fix this?

Yes



OH, you mean how do I fix this

Run these commands:

Code: Select all

sudo systemctl start smbd
sudo systemctl start nmbd

sudo systemctl enable smbd
sudo systemctl enable nmbd

[hengreer]

Hi,
I've tried running all 4 of those commands as suggested, As you can see below it came up with the error

Code: Select all

pi@raspberrypi:/ $ sudo systemctl start smbd
Job for smbd.service failed because the control process exited with error code.
See "systemctl status smbd.service" and "journalctl -xe" for details.
pi@raspberrypi:/ $ sudo systemctl start nmbd
Job for nmbd.service failed because the control process exited with error code.
See "systemctl status nmbd.service" and "journalctl -xe" for details.
pi@raspberrypi:/ $ sudo systemctl enable smbd

Synchronizing state of nmbd.service with SysV service script with /lib/systemd/systemd-sysv-install.

For good measure I had a look at the 1st file:

Code: Select all

Checked the fiile /usr/sbin/smbd $SMBDOPTIONS and it doesn't exist? Not sure what happened their but I've no idea which package to reinstall to generate that file.

Suggestions welcome.

[hortimech]

You can ignore that variable, if it isn't set, it will be blank and so ignored.

Does /etc/samba/smb.conf exist and if so, what does it contain ?

[hengreer]

It does indeed exist

Code: Select all

cat /etc/samba/smb.conf

[hortimech]

Well, after removing all the comments and default lines, this is the effective smb.conf:

Code: Select all

[global]
	workgroup = workgroup
	idmap uid = 16777216-33554431
	idmap gid = 16777216-33554431

	guest ok = yes

	security = user
	server string = Samba Server %v
	cups options = raw

[homes]
	comment = Home Directories
	browseable = no
	read only = no
	valid users = %S

[printers]
	comment = All Printers
	path = /var/spool/samba
	browseable = no
	printable = yes

[downloads]
	path = /root/downloads
	read only = no
	valid users = root
	public = no

Which is interesting because it is neither one thing or another, it is basically a standalone server, but lots of it would only make sense if it was a Unix domain member. If you are trying to set up a standalone server, remove the first block of lines from the smb.conf above (the ones between [global] and 'security = user') with the possible exception of the 'workgroup' line, if 'workgroup' is a replacement for the real workgroup name, leave it in, if it isn't, remove it.
I should also point out that, the supplied smb.conf isn't the default, it has been heavily modified.
The next question is, do you have a root user, because this is the only user that can really connect.

[hengreer]

Right due to the fact you say it's a heavily modified version I've decided the best thing to do is uninstall everything and try again, however I still have the same error as above, and this time there is no smb.conf file.

What OS are you using ?
If it is raspbian, the default smb.conf, with all commented lines removed (lines that start with '#' or ';') looks like this:

Code: Select all

[global]
   workgroup = WORKGROUP
   log file = /var/log/samba/log.%m
   max log size = 1000
   logging = file
   panic action = /usr/share/samba/panic-action %d

   pam password change = yes
   map to guest = bad user
   usershare allow guests = yes

   comment = Home Directories
   browseable = no
   read only = yes
   create mask = 0700
   directory mask = 0700
   valid users = %S

[printers]
   comment = All Printers
   browseable = no
   path = /var/spool/samba
   printable = yes
   guest ok = no
   read only = yes
   create mask = 0700

[print$]
   comment = Printer Drivers
   path = /var/lib/samba/printers
   browseable = yes
   read only = yes
   guest ok = no

Which makes it a standalone server.
Check your smb.conf now, if it looks like the above it should work, so try starting the 'smbd' & 'nmbd' deamons.

Code: Select all

sudo systemctl start smbd
sudo systemctl start nmbd

Or

Code: Select all

sudo service smbd start
sudo service nmbd start

Or

Code: Select all

sudo /etc/init.d/smbd start
sudo /etc/init.d/nmbd start

Or, if all else fails

Code: Select all

sudo /usr/sbin/smbd -i

The last one will log to screen

[hengreer]

I think I've solved that problem. I cleared it all out, purged it again, went and found the conf file and deleted it. Then whilst googling I found the advise to install the following.

It appears to have fixed the issue.

[hortimech]

Bit lost now, If you now install winbind, I could talk you through provisioning a Samba AD DC, or to put it another way, you do not need most of the packages you installed.

By installing the 'samba' package, you should get these packages installed as well:

python-dnspython python-samba samba-common samba-common-bin samba-libs

So this just leaves (out of the packages you installed) : libsmbclient libwbclient0 python3-smbc samba-dsdb-modules samba-vfs-modules

Ignoring 'python3-smbc', these are:

libsmbclient: for client applications to talk to SMB servers using the SMB/CIFS protocol.

libwbclient0; for client applications to interact with the winbind pipe

samba-dsdb-modules: support for various Active Directory features

samba-vfs-modules: Virtual FileSystem modules

None of which have anything to do with a Samba standalone server.

So congratulations on fixing it, but I just do not see how
