Networking issue: LMDE refuses to create share in home

I have two Mint computers:
A has Julia 64-bit.
B has Debian Edition 32-bit.
I want to share files across these two computers.
Both have open-ssh, sshfs, samba (server and client), and nautilus-share installed.
I have no problem creating a share in my home directory in computer A with main edition.
However, computer B refuses to create a share in my home directory, saying that I lack permissions.
I can create share as root but this share is not shown under my profile.
I have the same user on both computers (ckosloff).
I am trying to connect to A from B via ssh, but no luck.
I would rather connect via samba, because there are Windows computers on my network, but for the moment I could settle to make the two Linux boxes talk to each other.
I'll tackle the other problem later, please help.

I know there have been threads about this, personally I use NFS for my occasional file sharing with my laptop. I did a forum search for file sharing lmde and came upon this that should be helpful:
http://forums.linuxmint.com/viewtopic.p ... 3&p=382386
The bottom post mentions additional steps that are needed for LMDE. If you're just sharing with Linux and not Win and want to use NFS instead (I didn't want to learn to configure samba for linux sharing...) this was very helpful for me:

Linux Mint Debian Edition Preliminary Steps
Step 1:
"Guest Access" option is disabled by default. To enable it:
Open smb.conf as root:
Add the following lines to the [global] section:
And restart samba:
Step 2:
You do not have permissions to create a usershare because you are not included in the correct group.
Code: Select all
sudo gpasswd -a your_user_name sambashare
:
Add samba client packages
Code: Select all
sudo apt-get install gvfs-fuse
sudo apt-get install libsmbclient
sudo apt-get install smbclient
sudo apt-get install python-smbc
Then add yourself to the fuse group:

Logoff and Login again for all the group changes to take affect

Just noticed this in your original post:
I have the same user on both computers (ckosloff).
Linux Mint Debian's smb.conf has the old [homes] section enabled. It's not browseable like a normal share because it's created "on the fly" the moment the remote user asks for it. It uses the [homes] share definition as a template and creates a share of that users home directory at that moment.
Since you have the same user on both machines this may be the only situation where it makes sense to add a samba password for yourself and have remote access to your entire home directory:
Like I said above it's not browseable from another Linux box like other shares so you can only access it by specifying it by user name:
For example:
Code: Select all
nautilus smb://192.168.0.100/ckosloff
That may be a little too much sharing but I thought I would point that out. I'm not a fan of the admin user creating an smbpasswd for himself ( privacy / security issues ) but in this unique case it might make sense.

altair,
I see that you are a guru helping many people around.
I am working on your writings as time permits.
I prefer to digest everything thoroughly before messing up my system.
So, problem is not yet solved, give me a couple days, I might be back with more questions.
Thank you.

You've got 2 problems here:

On 192.168.0.116 make sure samba is running:
And, If you have enabled the firewall disable it.

I hate to tell you this but everything looks right.
[1] There is one thing that's my fault because I didn't explain it very well:
ckosloff@lmde10 ~ $ ls -al /path/to/Debshare
ls: cannot access /path/to/Debshare: No such file or directory
You did exactly what I said to do but not what I meant you to do. This is what I was after:
I just want to make sure that ownership and permissions are correct for the shared folder and it's parent folder.
[2] The other thing is rather confusing. From your previous post:
Nautilus in LMDE still refuses to create share.
'net usershare' returned error 255: net usershare add: failed to add share debshare. Error was Operation not permitted
And yet you created the share successfully:
net usershare info --long
[debshare]
path=/home/ckosloff/Debshare
comment=
usershare_acl=Everyone:F,
guest_ok=n
That's going to require a username and password to access but it should still be visible from the other machines on the network. Are you still getting an error?
[3] Can LMDE see it's own share. You can test that by running the following command:
EDIT: Sorry, didn't answer your last question.
to check the status of all the services:
To check the status of a specific service:
Code: Select all

I created the share as root, however it does not show up in Nautilus under my profile as shared, just as a directory.
It does show up shared to root.
Something is happening though, because POMPANO is the name of the Windows workgroup and TNACH is a machine in that workgroup that is turned on.

Posted from computer A (Julia 64-bit main edition).
Success!
I could connect to LMDE and see all my home directory, not just debshare.
It asked for my password, and it went straight through.
I noticed however that it said Workgroup: Workgroup, but that is not the name of my workgroup.
That probably is because my smb.conf on comp. A needs editing.
Here is:

Great !!!

That answers the question posed by the original title of this topic. If you created a share of /home/ckosloff/Debshare as root then the share definition will be owned by root. If you subsequently tried to share the same directory as ckosloff you would get this exact error message:
'net usershare' returned error 255: net usershare add: failed to add share debshare. Error was Operation not permitted
That's the way it should work. If you look at the ownership / permissions of "debshare" at /var/lib/samba/usershares you will see that it is owned by root with permissions to write by root but read by everyone else. When you tried to create the share as yourself you attempted to overwrite the share definition that's owned by root.
If you want the workgroup on Machine A to match the workgroup on LMDE then edit the smb.conf on Machine A and change the workgroup:
# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = WORKGROUP
Then restart samba:
On Mint - non-Debian the command is:

This is the content of file Debshare in /var/lib/samba/usershares
#VERSION 2
path=/home/ckosloff/Debshare
comment=
usershare_acl=S-1-1-0:F
guest_ok=n
If I change it to guest_ok=y
will it work?
How can I make it accessible?
We are making good progress but I still have questions, maybe this thread is becoming too long.
I can start another one if necessary.
I understood all your explanations, everything is clear to me, thank you very much.

Based on your earlier post it already is accessible so you have me confused again.
If you mean accessible to everyone then yes that last line will have to change.
But don't edit /var/lib/samba/usershares/debshare directly because that will not work. It won't work because the Linux file permissions on /home/ckosloff/Debshare won't be set right for guest access.
Instead go back to Nautilus ( as root since root owns the share definition ) > Right Click /home/ckosloff/Debshare > Sharing Options > enable "Guest access" and then it will ask you if you want it to modify permissions.

Well, the whole home folder is accessible, and also Debshare, but as a folder, it does not show the share icon.
I did follow instructions, and, as root, enabled guest access.
Restarted computer and Debshare still does not show the little hand icon.
I feel like deleting this share altogether, there is nothing much in it, I just created it for testing.
I managed to create under my profile another share, called dinoshare, this one shows the icon and everything, so I guess that part of my inquiry is done.
I have other questions though, because the Debian computer cannot access the Main, and I still have to be able to connect to Windows shares, and the Windows computers should be able to see my Linux shares (is that possible?).
By the way, the samba daemon is running in Main too.
So, what do you think of opening another thread to handle these other questions, in order to keep the forum nice and tidy?
Thanks for all the help!

I posted a tad bit in haste.
The Debian machine is always accessible from Main, but only with the IP address.
I checked on the router, and there is no name for it, although terminal does show a name for this computer (lmde10).
Surprisingly, the main edition computer does have a name in the network (Julia-Pavilion).
I would like the LMDE to have a name too, how do I go about it?

Don't base anything on the little share emblem in nautilus - it's an unreliable indicator if something is shared as it appears and disappears apparently based on temperatures and humidity levels.
Besides even when it's working it will only display that emblem to the user that created it ( root ).

Your Debian machine does have a name. By default Samba will use the host name of the computer it's running on as the netbios name. When you ran smbtree on the Debian machine it listed your share with the correct netbios name:
\\LMDE10 lmde10 server
\\LMDE10\debshare
\\LMDE10\ckosloff Home Directories
\\LMDE10\Print_to_PDF Print to a PDF File
\\LMDE10\IPC$ IPC Service (lmde10 server)
\\LMDE10\print$ Printer Drivers
If the other computers can't see lmde10 then this isn't really a samba issue it's a networking issue. The first thing you can try is to reorder the way the Debian machine announces it's presence to the network:
Add a line to the [global] section of smb.conf:
Code: Select all
name resolve order = bcast host lmhosts wins
Save smb.conf and restart samba:
Wait a few minutes for the network to settle down and see if others can see your Debian machine.
BTW, can you post the make and model of your router. There's a way to have your router issue a static ip address to your machines using something called "DHCP Reservation" that can also be used to fix this networking problem.

Hi altair,
Thanks for continuing support.
Added lines to smb.conf, restarted samba, then restarted computer, then restarted whole network.
Same situation: router still does not see the name for 192.168.0.116.
Moreover, I get this error:
Could not display "smb://lmde10/ckosloff/"
Error: failed to mount Windows share
Please select another viewer and try again.
I can access via IP.
Regarding router: it is a D-Link DIR-635.
It can only assign one reservation and it is taken by the network printer.
Otherwise it would be a nightmare after each lease renewal.
It is strange that all devices connected to the router have a netbios name, except for lmde10.
BTW, I have a problem in main computer too, it cannot display its smbtree, but I reserve that one for the networking forum.
Just mentioning this for the implications it might have here, because I am using main to connect to lmde10.

I have a D-Link router myself ( not your model ) and if there is a limit I'm not aware of it ( I currently have 8 Reserved DHCP ip addresses ). The 635 even has a table where you can list all of them:
Screenshot.png
It's true that the lease will expire at a given interval but it will renew to the same reserved ip address. I've had the same ip address on one of my boxes for 4 years. While you're in there you might want to make sure your "Always broadcast" box is checked.
It is strange that all devices connected to the router have a netbios name, except for lmde10.
I've got a funny feeling your firewall is getting in the way assuming you enabled one on LMDE. You can check it by installing the following package:
And running the following command:
Code: Select all
sudo nmap -sS -sU -T4 192.168.0.100
You need the following ports to be open for samba to work:
PORT STATE SERVICE
139/tcp open netbios-ssn
445/tcp open microsoft-ds
137/udp open|filtered netbios-ns
138/udp open|filtered netbios-dgm
BTW, I have a problem in main computer too, it cannot display its smbtree, but I reserve that one for the networking forum.
You mean that smbtree comes back blank or it lists everything on the network except it's own shares?
