Networking :: Samba Client Accessing Windows Shares On Secondary Subnet
Sep 13, 2009
I have a machine acting as a gateway for a private network. While it can ping hosts on that private network, I can't use samba (smbclient or smbmount) to access shares on hosts on the private network from that machine. Other machines on the private network can access shares on other machines - just not the gateway server.
Here's how the gateway is configured:
When I try to connect to ports 139 or 445 (via smbclient or smbmount) the mount() system call times out. As I mentioned above, I can ping those hosts, so UDP packets work but TCP packets seem to get blocked or lost.

I have a NAS running Samba. My Samba shares are accessed from a Windows computer, it works very well.
With the kubuntu 10.04 computer, things are different : I can see the Samba shares in Dolphin, and copy files to the local drive, but lots of applications don't allow me to open a file on a Samba share.
Some applications such as OpenOffice let me browse to the share but refuse to open the remote file
Some other applications don't let me browse to shares at all.
What's up with that ? Surely I'm not the only one wanting to access files on a NAS ? How do other people do it ?
PS I chose kubuntu 10.04 because the 10.10 install hangs, the "ui" workaround I saw here and there did not work, the only solution offered was to go back to 10.04

I'm trying to do the normal setup of sharing some dir's on my linux machine using samba, to allow a windows laptop to access them.
I've managed to get the printer shared and this is allowing to send print jobs, which come out beautifully! however the actual file shares still aren't accessible
Depending on my settings, if I have security = user then when I access from the windows machine I get a username and password box - I dont want this functionality, I want the system to access right away as it would between two windows shares.
If i change security = share then it simply lists the shares, but tells me they are all inaccessible.
I've googled and searched here, tried various different things but I just can't see why/where its asking me for the username/password combo.

Since "upgrading" (ha!) to lucid I have had a number of problems that I am working my way through. The latest is accessing samba shares from a Win7 PC. It takes minutes to open the requested share from the Windows 7 PC. File transfers, once the directory is accessed, can be measured in bytes. It is an absolute trickle.
AFAIK the smb.conf is unchanged and, in any case, there is no problem accessing the shares from another linux PC.

My environment in a nutshell is like this:
- I'm a member of a Windows AD domain environment that spans many different subnets.
- My client workstation (Windows XP) is part of this domain and resides on one subnet.
- The server I'm trying to get Samba working on (SLES 10) is part of the same domain but resides on a different subnet.
- I want to access shares on the SLES 10 box from my workstation.
Here is what does work:
1. I can ping the workstation from the SLES box, both by hostname and ip.
2. I can ping the SLES box from my workstation, both by hostname and ip.
3. netstat -an shows that the SLES box is listening on ports 139 and 445.
4. I can telnet from my workstation to the SLES box on ports 139 and 445.
5. Output from smbclient -L coolserver (hostname obfuscated):
Code:
Anonymous login successful
Domain=[COOLDOMAIN] OS=[Unix] Server=[Samba 3.5.8-30.4-2516-SUSE-CODE10-x86_64] .....
Code:
Enter cooluser's password:
Domain=[COOLDOMAIN] OS=[Unix] Server=[Samba 3.5.8-30.4-2516-SUSE-CODE10-x86_64]
smb: >
So, cross-subnet communication seems to be working in a general sense and I have verified that my share is present and accessible by my chosen user id.
Here's what doesn't work (from the workstation):
1. Output from net view \coolserver:
Code:
System error 64 has occurred.
The specified network name is no longer available.
2. Output from net view \coolservercoolshare:
Code:
System error 5 has occurred.
Access is denied.
3. Same output as above if I try to connect via IP.
However, when I run any of the above commands from my workstation, I see the following in log.smbd on the SLES box:
Code:
coolworkstation (10.49.140.36) connect to service coolshare initially as user cooluser (uid=12171, gid=500) (pid 29039)
[2011/07/08 00:39:29.098422, 1] smbd/service.c:1251(close_cnum)
coolworkstation (10.49.140.36) closed connection to service coolshare
I'm not really sure how to interpret this because those are the exact same entries that get logged when I connect to the share locally, via the smbclient utility on the SLES box, which works fine... but from the Windows box I get the "Access is Denied" or "The specified network name is no longer available" errors. I also occasionally see this in log.smbd:
Code:
[2011/07/08 01:01:19.858308, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown
[2011/07/08 01:01:33.828692, 0] printing/print_cups.c:108(cups_connect)
Unable to connect to CUPS server localhost:631 - Connection refused
[2011/07/08 01:01:33.832127, 1] smbd/server.c:282(remove_child_pid)
Could not find child 29781 -- ignoring
I don't know if that is relevant. I created the Samba user via the smbpasswd utility and my smbusers file maps the system user directly to the Samba user, both of which have the same password. Here is my smb.conf:
Code:
[global]
workgroup = COOLDOMAIN
netbios name = coolserver
domain master = no
preferred master = yes
local master = yes
wins support = no .....
My workstation and the SLES box are both pointing to the same WINS server, which services the entire domain (which is also one of the DC's and one of the DNS servers). I'm really not sure what's going on. I'm guessing it probably has something to do with the subnet boundaries or the WINS configuration or something along those lines. I just don't understand because the smb daemon seems to be logging "successful" sessions from my workstation... but then the session just insta-closes.

i have 3 ubuntu machines running 9.10. All of them are running SMB so that the Windows machines can access the shares on the Ubuntu machines, but the ubuntu machines can not access shares on the Windows machines. When I click to connect to a windows machine ( all of them running XP), it says "connecting to COMPUTERNAME.." It never opens the computer, and it always comes back with an error saying that it failed to connect. I haven't been using ubuntu for very long, so im not as savvy with it as I am on windows. All windows machines can see all ubuntu shares, just not the other way around and I'd like it to be both.

My network is barely functional. I'm running 2 linux servers connected by openvpn (tun) through routers on both sides. There are Windows clients (98 and XP) on both subnets. One server (ls3) acting as PDC for the domain. The Windows clients use the respective linux boxes as gateways. On the server side (ls3 which is both openvpn server and samba server), all the clients can read/write properly to shares on both sides. The problems are all on the client side. Share connections to the server side disconnect after a few moments.
Browsing on the client side windows machines is fine. I can see shares on the server side. Some server side files open and are readable, writable, other server side files will not open. Some samba logon scripts on the server side can be opened from the client side. Others open after a long wait to a blank file! Permissions on server side files are set to 777 for testing. If a file won't open or reads "blank", that doesn't change no matter how many times you try. A non-readable/writable file overwritten by a readable/writable one can be read and written to!
I can ping successfully from any client on either side to any other client by either ip address or workstation name. Firewalls on both side are set to forward tcp and udp traffic going to port 1194 to the respective gateway linux boxes. Iptables on both linux gateways are down for testing. I tried reversing the openvpn server/client roles with the same result; the same physical side of the network had the problem. On one of the windows 98 clients, I wiped out the networking configuration completely and rebuilt it from scratch. Same result.
One one of the windows xp clients, I tried to rejoin the domain. It went through successfully but the result was the same as above. The network was operating smoothly for several years until the client side dsl modem broke last week. It was replaced with a newer model and at the same time I migrated from a pptp connection to openvpn. How to resolve this, Is this something to do with openvpn? Is this a network hardware problem? Am I missing something in the port forwarding on the routers? My smb.conf files are ancient except I added interface tun0. I have never seen 2 files sitting next to each other in the same directory where one opens and the other doesn't!
I'm running Mandrake 9.2 on the client side and Mandriva 2008 on the server side. I have a Sonicwall firewall on the server side, a Westell 7500 on the client side. I note that during the modem install, the http port was opened to the linux box on the client side and the access log got huge over the weekend and I ran out of disk space until I closed it down and deleted the log. I tried a simple test while viewing /var/log/daemons/errors on the client side. From a windows workstation in the client subnet, I opened a dos window and tried to print a file located on the samba server on the openvpn server machine which I knew NOT to be problematic.
The file printed and there were no errors reported in the log. I repeated the test with a known problematic file. The file would not print. The errors log noted:
Authenticate/Decrypt packet error: packet HMAC authentication failed
I regenerated the static.key file on the server side and scp'd it to the client side and restarted both openvpn's. I checked for duplicate files named static.key on both sides. Same error.

I just got my Ubuntu 10.10 laptop to finally be able to access my Windows 7 Professional's shares, and I'd like to share how I got it working. Whenever I would go to Places > Network on Ubuntu, and then double click on my Windows computer (sometimes after finding it in Windows Network > {workgroup name}), it would immediately bring up a box saying "Password required for {computer name}". My Windows password wouldn't work here, but I didn't even want to be asked for a password. In Windows, under Network and Sharing Center > Choose homegroup and sharing options > Change advanced sharing settings..., Turn off password protected sharing was already selected.
So, I eventually found out that samba (the program Linux uses to talk with Microsoft's SMB network share protocol) has a bug of sorts. The format of the SMB packets coming from a clean Windows 7 is known by samba. However, if you install Windows Live Sign-In Assistant (which is provided through Microsoft Update) on Windows 7, the packets coming from Windows 7 are modified, and samba can not handle this. A patch has been written for samba, but Ubuntu's repositories (which has samba version 2:3.5.4~dfsg-1ubuntu8.1) does not yet have that patch.
Also, it seems Microsoft has stopped Windows Live Sign-In Assistant from appearing in Programs and Features. It doesn't appear even if you specifically download and install it separately. I did, however, notice that the installer calls itself Windows Live Essentials 2011. So I found that in Programs and Features, and uninstalled it. It asked which components I wanted to uninstall, and I selected all of them. Rebooted Windows, and now I can access the share no problem. I also grabbed the offending packet using Wireshark before and after that uninstall. The packet is indeed different. Specifically, without Windows Live Essentials 2011, there is no mechToken in the packet.
The current version of samba available is 3.5.6. I may try downloading and compiling that later, and see if it deals with the change that Windows Live Essentials 2011 makes OK. Also, it may be possible to get the share working without uninstalling every single Windows Live Essentials 2011 component. You may want to try that if you would like to keep a component.

We are using spare parts (Socket 775 Biostar motherboard, OCZ 500wat PSU) to build a computer that will just be another system in the house. I want this system to be running Folding@Home, and the F@H SMP client for Linux is much less of a headache than its Windows couterpart, so I would like this computer to run Fedora. My dad loves networking, and knows how to do it in XP / Vista, so he has always opposed my frequent use of Linux. There are ways of accessing Windows shared folders from Linux, but that I haven't figured it out yet. I want to access Windows shared folders from my Fedora 10. I don't know how to go about doing this, can anyone point me in the right direction? Do I have to install anything special? I can go to Places, and then Network (in Gnome) and I see "Windows Network", but when I click it, I get "Unable to mount location Failed to retrieve share list from server"

I wonder how to get Samba share access working well...Dolphin supports Samba but it doesn't really mount anything, it seems... Non-KDE Applications therefor can't access samba that way. In Gnome there was a workaround for the same problem. You could simply go to ~/.gvfs in any application and find the samba mounted there.Is there anything like that in KDE? I set up a Samba mount via /etc/fstab for now but that is quite annoying because it fails after each Suspend, changing WLAN Access Points, etc. Then I have to go to the console and manually launch sudo mount -a to get it working again. How can I make things more comfortable?
P.S.: I'm even up for using something else than Samba to talk to my fileserver. However I don't know of anything that would work better in this regard. (NFS would have the exactly same problem for example)

I am having a problem accessing my samba shares from my notebook that has a fresh install of Fedora 15. I know that the server with the samba shares is working since I can access them from the windose box. I have just moved from using Ubuntu to Fedora and have definitely found my home. How would I tell if samba is running (or any service for that matter) on my notebook? I Installed samba-client
Code:
yum install samba-client
Though I still cannot access the shares. All it shows is windows network.

provide support for a small business that uses Windows machines to access files stored on an Ubuntu server which has just been upgraded from 8.04 to 10.04 (32 bit version). Before the upgrade the users accessed their share by this batch file:
Code:
net use x: \servernamesharename /user:username
This would then prompt the user for his or her password which they would enter to allow them access to the share.Since upgrading to 10.04, the user gets a "system error 58" stating "The specified server cannot perform the requested operation"If the batch file command is changed to:
Code:
net use x: \servernamesharename
The same error message is given. The only work around I have found is to modify the file to read:
Code:
net use x: \servernamesharename /user:username password
This is not ideal at all as it makes the password protection useless.When I performed the upgrade I left the smb.conf unchanged. The smb.conf file is:
Code:
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.

# This is the main Samba configuration file. You should read the

When I boot up, or come out of standby, etc, it takes about a minute for my Windows shares on Win 7 to show up under Network. Is there anything I can try that will make this initial connection faster? Either on Debian or the Win7 machine? I have the latest Debian vanilla. This is over wifi. My other devices list the shares right away.

I have a problem with 'Samba' shares on Ubuntu 8.04. Bringing shared folders over from Windows (on another computer) is not a problem...until I try same process with a Windows backup folder holding .tib data from an 'Acronis' backup.The files appear in Ubuntu Network, everything looks o.k., Ubuntu just won't copy the data to another folder. Other shares work without a problem, its only with these ':.tib' data.

I setup shares on a fresh install of Ubuntu 9.10 via the shared folders application from here: [URL]. The shares are visible on my vista laptop but when I go to open them I get an error "you might not have permission to use this network resource". I set the smbpswd to nothing via the method in the above article as well and my /etc/samba/smd.conf has the follow lines:

Been trying to deal with this one for some time, and still not sure it's more or an issue on the Samba or Win 7 side.
Running Ubuntu 10.04 with Samba 3.4.7, using Windows clients from 2000 on up to access shares.
2000 and XP have no trouble both connecting initially to shares, but upon reboot the shares are disconnected and do not automatically reconnect unless one of them is double-clicked on. Passwords and mappings are saved such that Windows tries to reconnect upon restart. When manually reconnected in this way, shares remain open as they should. This isn't a big issue, but it would be preferable to have these shares reconnect so that links and shortcuts across the LAN work right from bootup.
The bigger issue is with Vista/Windows 7 - When shares are set up with appropriate passwords and such on the clients, they work as expected, until the client is rebooted. After signing into windows 2 things are observable:
- Black screen for 2-5 minutes before desktop appears
- error message appears when you try to double-click on a mapped share (even with a saved password) that the connection cannot be restored.
If you go into credentials manager and delete the saved password for the share(s) on the samba server, you are prompted for the password when you try to open any of the shares - reenter it and you're then fine until the next reboot.
There must be some issue with the persistence of the saved password, but not sure if this a Windows-side issue or not. Read some other info on this, and had to make the following changes earlier to even get Win 7 clients to connect to samba at all:
[URL]
It appears that when Win 7 starts up, it simply can't connect using the saved password, and the desktop doesn't come up until the reconnecting action(s) time out (if you disconnect your win 7 machine from the network the delay is not present).
It's not a game-breaker, but really annoying when rebooting having the delay and reentering the network share password(s).

I have a redhat server with SAMBA file services. I have copied all the users files into their respective home directories and mapped a network drive to their folders. However, when I try to access a file in those folders the machine reboots itself. There are no error messages or anything, it just reboots!

We have an existing Windows 2000 network that I am trying to add an Ubuntu 8.04 server to. I have put links into the windows domain DFS to the linux machine's samba shares.
The shares work fine for local users that are physically on the same network (192.168.0.X). Remote users from other offices or dialing in with a vpn client can not access the these particular folders off the DFS. However, they can map them directly from the ubuntu server.

I have an Ubuntu Server 9.10 box running Samba 3.4.0. It has 4 shares, one of which is a CIFS connection to an XP machine, another of which is a password protected share. All the shares work fine and well. However, lately the client has called to say that "everything's hanging and freezing" when they browse the shares via Windows Explorer (approximately 30+ PCs on network, variety of XP, Vista and 7 OSes).
Not all users always experience the problem, and I remote in to test when I hear this via an XP machine, and today for the fist time I also experienced this problem - browsing literally sticks and hangs. No entries in PC's eventviewer. They are running on Netgear switches, all the same age, a couple of months old. A simple reboot and and everything's fine again for an indeterminable time, then I get another phonecall and an unhappy client on the end!

At the school i work in i have a server2k3 server that provides a domain to all the windows clients, aswell as a fedora server that acts as an imaging machine and webserver.
Im rather concious of the fact that if for any reason the Server2k3 server was to die there is no backup of active directory, or anything that can take its place whilst a replacement is found.
So is it possible to use a fedora machine with samba as a secondary domain controller? so it can be used as a login server, and has a copy of AD.

I'm trying to connect to a Samba share on a VirtualBox'ed Windows 7 that is connected to an openSUSE host in bridged mode. For reasons beyond my comprehension I cannot use the shared folders feature, so I'm using Samba instead. I configured a share through openSUSE's Samba server configuration tool:
[iTunes]
inherit acls = Yes
path = /home/myusername/iTunes
read only = No
valid users = myusername
I also set a password for this user using smbpasswd -a myusername. I can go to smb://192.168.1.6 on the host machine and log in to the share successfully, but on Windows 7 I see this: What am I doing wrong? I can connect to the shares list without any problems. It's just the login that doesn't work.
Update: I noticed that my Samba server is part of the WORKGROUP domain.
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.7-1.17.1-2505-SUSE-SL11.4-x86_64]

We have a samba server with a couple of shares defined as follows:
Code:
[Storage]
comment = Storage
browseable = yes
path = /home/samba
writable = yes
[Backup]
comment = Backup
browseable = yes
path = /mnt/hd2/home/samba
writable = no
[Administration]
comment = Administration
path = /home/adm
valid users = adm
public = no
writeable = yes
browseable = no
We have two samba users: samba and adm. The first is used to connect to Storage and Backup shares, and adm is used to connect to Administration share. There are two problems:
1) If Storage and Backup shares are connected to a Win7 box, the Administration share cannot be connected. All we get is an error saying that that share is already connected with different username.
2) We have managed to work around this by connecting the Administration share with the IP-address of the server instead of it's name(?!). The problem then becomes that sometimes connecting Administration share this way makes Storage share read-only. Not always though.
Wrong "security" type in smb.conf (was "user", needs to be "share"). For some reason the Storage share still occasionally gets connected read-only. Win7 also tends to forget the passwords/usernames for some shares upon reboot (not all of them, though).

I am in the process of migrating my small workplace to a basic spin i've created of f14. Everything is suave but some file browser windows eg: file upload in gmail, hotmail etc, does not show my samba shortcuts i've created nor even the option to browse the network in the "places" section. It shows other locally created shortcuts but no samba ones. Just to test it, even creating an ftp:// shoftcut yeilds no dice. I had a quick search through the forums and I couldn't find anything. I have a feeling this has an easy solution that my inferior brain cannot comprehend! Loving F14 on my macbook pro and so are my employees in my office! Feels much less bloated than Ubuntu IMHO.

Package samba is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
However the following packages replace it:
