Hi,

I'm running Samba 3.2.5 on a server which I'd like to shut down when it

Is there a way to detect whether any user has opened a file on the

smbstatus will tell you.


slight correction,

smbstatus tells you what file are used and by who, currently.
not who HAS opened a file.


smbstatus will also tell you who has an active connection to what
shares, even if they have yet to actually open some file.

while it's possible for someone to open a file in app that reads to
ram then closes, such as notepad.exe, making edits and letting them
sit without saving for long enough that an smb client would disconnect
the session is unlikely given the save often mentality that most
have gotten from using PC's.  From application crashes, to power
outages, to 2 year old kids pressing buttons, save often!


Thanks for your suggestions!


so depending on what you mean by has opened (opened before and still
use it, or opened before and may have close it), smbstatus may be the
answer or not.


By has opened I mean opened before and still use it. Actually,
something more like would be disappointed if the server went down.
Ideally, a user might e.g. open a couple of source files to analyze them
and after a while (without making changes of saving anything) try to
open another file in the same directory.

I've done a couple of experiments with smbstatus, specifically its -S
and -L options. My clients run Windows 7 SP1 and Windows XP SP3. While a
Windows Expolores is opened for a share (or one of its subdirectories),
smbstatus -S will list that share. But once the Explorer is closed,
the entry is cleared. Similarly, using a File Open Dialog only produces
a short lived entry.

smbstatus -L does not seem to produce any list entries once a user has
opened a file. May be I have to specify some more specific locking in
smb.conf?

I've also experimented with root preexec and root postexec. Those
seem to be triggered at the same time the output of smbstatus -S changes.

Currently, I'm not even sure Samba preserves the kind of state
information required to detect the usage scenario  I'm interested in. Is
there any concept of an open file in Windows/Samba, after all? May be
it depends on the application used to open the file?




I suggest trying smbstatus -B too (shows byterange locks).

Also, reading the whole thread it seems to me (FWIW) that the only way 
to be 100% sure that a samba restart won't disappoint anyone is have 
smbstatus show no active connection.

Hello,

AFAIK the FUSE filesystems have in common the problem that they are read
only. I have to write to this share too.

My idea was a samba VFS that, when it finds a compressed file with a
certain extension ( say .gzvfs ) allows a normal read access to this
file but allows to read and write to other files

Hello,

Except at least ntfs-3g which is read + write (see
the link posted yesterday). It is fully compatible
with Windows, which may be useful in a Samba environment.


My idea was a samba VFS that, when it finds a compressed file with a
certain extension ( say .gzvfs ) allows a normal read access to this
file but allows to read and write to other files


Windows XP (and later) and almost all Linux file managers support 
viewing a compressed file (e.g. zip archive) as a normal folder. This 
feature lives inside the file manager application and doesn't require 
any server-side support.




For ntfs the compression is transparent. No specific
extension or change needed in applications or scripts.

Regards

Jean-Pierre



I recently read somewhere about a user that was exporting via samba an 
ntfs volume created under windows that had the compress option activated.
When writing to the share via samba he could create files but not 
overwrite them. Reason is ntfs-3g driver doesn't support overwriting 
transparently compressed files. He solved the issue by mounting the 
volume under Windows and deselecting the compress option.
I'm sorry but I don't remember if that post was recent, and can't find 
it againt right now.

Andrew,
  thanks for your response. Now that you mention it, I remember
having read something about the need to pass through 2K3 to land on
samba4. I'll investigate that detail (obviously I'd prefer to avoid
setting up a 2K3 server just to migrate...)

more stable samba3 (samba4 being alpha as of today ?).


It's a simple matter of what you want it to do.  You can't do printing
with Samba4, and the file server is best used for just the AD shares,
but on the plus side you get an AD server, and a smooth migration path
from AD (you can't migrate AD to Samba3 without rejoining machines, and
the loss of AD features).

You can of course try the direct W2K migration - the issue that is know
won't be a silly, un-noticed bug, it will either work or not.

Andrew Bartlett



I think I'll try the samba4 route.
The file server is already on a separate samba3 debian machine, so 
nothing would change on this side.
I'll have to do some research on whether I can move the print server 
funcionality onto the existing file server or setup a windows machine 
which would do just that.


Thank you for your suggestions.

Hi,
we have a mixture of windows 2000 and xp workstations which use a

If for some reason the winbind daemon doesn't start on the fileserver, 
the 2K clients are not able to access restricted folders (e.g. user A 
would get access deined errors when trying to browse folders owned by A 
with perm bits 600). No problems with the public folders.

For the XP clients, the presence of winbindd makes no difference.

AFAIKT, the winbind daemon is required to map domain users and groups to

Following issue only occurs on a Windows XP system (it doesn't happen on

I have Ubuntu 10.10 (Maverick) server with samba 3.5.4. The server has a
samba share and another PC (which has Windows XP as operating system) is
connected to that share through a network drive. On the share, there are PHP
files which can be changed by a developer. The files are also available by
HTTP using an Apache HTTPD VirtualHost.

So, the developer has some PHP files open in PHPDesigner 7. He makes a
change and he wants to see his change in the browser (e.g.: Firefox). He
refreshes the page and he sees the result. Now, he returns to PHPDesigner
... but ... PHPDesigner is telling him: This file has changed, do you want
to reload it?.

The problem is: the file hasn't been changed, but the access time of the
file has. I had a look at this issue and I noticed there's no creation date
on Unix level. So in Windows, creation date is access time ... which makes
Windows XP thinks the file has been changed as it was accessed ...

Any idea's how we can solve this?


I have a very similar issue: MPLAB IDE code editor says source file xxx 
has changed, do you want to reload it ? every time I build a project, 
even though no modification has been made to the source file. The entire 
project is hosted on a mapped drive on a debian system. The MPLAB IDE is 
installed on Windows XP SP3.


There are no other problems a part from this annoying popup alert.

fileserver:~# cat /etc/debian_version
5.0.6

fileserver:~# smbd --version
Version 3.2.5

I belive windows is reading file atime as if it was mtime, thus thinking 
file has changed.

Regarding winbind, I find it strange that it didn't get installed along

That's also what I thought, but /etc/init.d/ contains two separate
scripts (smbd and nmbd; no trace of samba, as specified in the
Ubuntu documentation www.tinyurl.com/ubuntu-samba-doc), and since
since I couldn't see the shares from Windows, I figured I might have
to launch both separately.

/etc/init.d/smbd doesn't seem to launch nmbd, but I'm no shell expert:

Yes, it seems to care only about the process name it's been given, smbd 
in this case. I havent studied upstart so it might also be possible that 
somewhere in its configuration it's specified that smbd goes along with 
nmbd. But that's just useless speculation...

The problem is that I couldn't find an up-to-date documentation that
would say precisely what needs to be installed in Ubuntu and show a
very basic smb.conf that would work. Docs either assume people will
just append their stuff to the big default smb.conf... and somehow
figure out what packages need to be installed.


I usually do something similar to aptitude search samba and install what 
seems to be the main package, which hopefully will pull all the 
required dependencies. Then I install the -doc package, which tipically 
contains the up-to-date docs.

But I'm sure you already know that :-)



Don't know about available param, but public and writable shouldn't 
affect visibility of the server in windows neighborhood.


I added those because I saw them in some documentation... but at this
point, I'm clueless at what packages are really needed, and what needs
to be done in smb.conf to share a writable folder.


maybe add

guest ok = yes



Actually, I'm seeing something funny... but this is for another
thread.

Thank you all for your help.

If the ping from xp to the ubuntu server doesn't work either way (by 
specifying the server hosntname or its ip address) then I think you 
should check your network before struggling with samba config.


Just my 2 cents, HTH.

Thanks for the help. I can connect through its IP address (I could

\\ubuntu\share - The network path was not found.

If you know Ubuntu 10.04, could there be some security that prevents 
Samba from working?




My servers are pure debian, so no I don't know of Ubuntu specific tweaks.
I'd try to enable wins in samba and raise its os level (though it should 
already be higher than xp), but it could also be that xp refuses to 
revert to netbios name resolution (i.e. broadcast). I've seen this 
behaviour once, but can't remember right now what it was exactly...

Hi,
   here's a quick explanation of the top fields:

Mem total = the amount of physical RAM you have available.

Mem used = total amount of RAM  the system is using. What you want here 
is a number as close to Mem total as possible, unless you find it useful 
to fill your ram banks with costly unused chips... :-)


Mem free = this is of course total - used, so you want here a number as 
low as possible.


Buffers = amount of RAM used for various types of system buffers (e.g. 
network buffers). This amount varies with the workload. For example if 
you are copying a disk image over the network you'll have a large value 
here.


Cached = amount of RAM used for disk cache. This value varies with the 
current workload too. It is used to avoid reading directly from disk 
something you have already read once. Roughly speaking, if a client 
requests a 10M file, it's first read from disk but then it remains in 
memory so that if another client (or the same one) requests the same 
file, the system doesn't have to read it again from the (very slow) 
disk, but can serve it directly from (very fast) RAM. The disk cache is 
not allocated by the applications, it is instead managed directly by the 
kernel, so if an app needs more ram, the disk cache is sacrified.


Thus you can count buffers and disk cache as free memory (i.e. not 
allocated by apps).

Re: [Samba] Is there a maximum number of shares samba can serve?

Eric Boehm ha scritto:

I am being asked to determine the feasibility of serving hundreds
(300-400) of directories as individual shares instead of sharing a single
parent directory.

Personally, I don't think this is a good idea. Clients will go from
having a single connection to a single share to 50-300 connections to
multiple shares. That can't be good for performance or load.

I've searched the mailing list, the web, the documentation, the wiki
and the source code. I haven't been able to determine the maximum, if
any. Of course, I may have missed it. Feel free to point me to the
correct documentation or source file.

I've seen some references that you can't have either more than 145 or
165 shares per samba server.

However, if there is anyone running such a large number of shares and
has advice, I am happy to listen.



Hi,
I found some docs about this smb.conf parameter:

usershare max shares

which specifies the maximum number of shares that the samba admin will 
allow non-root users to create via the command


net usershare add

( read for example 
http://us1.samba.org/samba/docs/man/manpages-3/net.8.html )


The example value given in the docs for the usershare max shares 
parameter is 100, which makes me think that a samba server should cope 
with a number of shares in the hundreds.


I know it's not much, but I HTH nonetheless.

Re: [Samba] Very slow initial opening MS-Word and MS-Excel files from Samba

The first time a Word or Excel file is opened, i.e., when either Word or 
Excel have not been actively running recently (like, say for several 
minutes or more), the time it takes to start the application and load

Once the first evolution is complete, files open more-or-less instantly 
if I close the first document but leave either app running (but void of 
any open documents). This pertains to the same file opened a second 
time, or different files -- once Word/Excel has done whatever it is 
thats takes so long for initial start up, then load performance is 
acceptable (in fact it is very impressive!).


And it is not merely the loading of the app, because it happens both 
when I start the apps implicitly by double-clicking on a document in 
Windows Explorer, but also if I first start Word/Excel explicitly from 
the START menu without a specific document and then open one from the 
Samba share using File|Open.


Envirnoment:

Server is RHEL 5 with Samba version samba-3.0.23c-2.el5.2.0.2

Desktops are XP Pro SP2 on some, and XP Home SP2 on others.

MS Office Suite is XP Pro (i.e., Word/Excel 2002)

Desktops also run Symantec Corporate Edition 8.1 (although same problem 
continues on a machine from which I uninstalled that as part of my 
debugging.)


I initially had no explicit settings regarding opportunistic locking in 
smb.conf, but I've tried server different configurations without 
improvement. What appears below is the current configuration and the 
problem still pertains.



smb.conf:

[global]
workgroup = mygroup
server string = Samba Server
hosts allow = 192.168.123. 127.
cups options = raw
log file = /var/log/samba/%m.log

create mask = 0765
directory mask = 0775

Active Directory is not used. All workstations (about 25) simply map 
drive letters locally.


This performance problem appeared only after we began using Samba for 
file server. Never saw this in close to 15 years of using Netware -- so 
I suspect it is not purely an MS-Office problem, but something to do 
with the interaction between MS-Office and Samba. I eagerly await your 
help!





Have you tried copying (tens of MBs) files or even those same office 
files to/from the share ? What is the performance there ?


I had a similar performance problem which showed up in Office, but I 
found out it was not limited to office files, but affected the

Thanks for the tip. I did a packet capture when the share was working
quickly and when it had slowed down again following a reboot.

Now I'm a bit confused. Both traces show roughly the same number of
packets and the server response time is about the same in both cases
(somewhere between 0.1 and 0.2ms on average). However in the slower
trace, the time between the client receiving a response and sending its
next request is much larger - about 15ms versus 0.2ms.

It would appear, then, that the Samba server isn't at fault. The client
is experiencing long delays between submitting requests; which seems to
fix itself following some pattern of usage that I haven't yet figured out.

How weird. :S

I had a performance problem that was related to how the XP tcp/ip stack
manages ack packets. Maybe what I'm going to say is relevant to Vista, too ?

My client is Windows XP SP2, my server is Gentoo Linux running samba
3.0.22, network is 100Mbit on the client, 1Gbit on the server. The share
is mapped as drive K:, and is mounted on a couple of 10K rpm U160 scsi
drives (software raid-1).
Client PC has 1GB of ram, the server 2GB.

I never had performance problems on my client machine wrt. network
transfers. One day I noticed that accessing data on the network share
was terribly slow; the throughput dropped to about 200-300KB per second
max., while it usually reached 8-9MB/s while copying large files.
From that day the performance has not increased no matter how many
times  I rebooted the server or the client.
The strange thing is, I'm not the only one using XP SP2 on the same
share, but no one of my colleagues has reported problems to me (I'm the
network admin).

Googling around I found a forum where the following changes in the XP
registry were suggested:

HKLM ==
  System ==
CurrentControlSet ==
  Services ==
Tcpip ==
  Parameters ==
Interfaces ==
  {network interface GUID} ==
 TcpAckFrequency == DWORD: 1
 TcpDelAckTicks  == DWORD: 0

I creted the two keys (they were not present), set their values and
rebooted the client machine (no server reboot).
The performance returned to the expected levels, and has been so for
some days now.

 Hello All,
 
 I'm running Samba 3.0.24 as PDC and file server on Gentoo Linux,  
 AMD64, 2.6.19 kernel, 100MBit/s network, and experience quite slow  
 file transfers from Samba to WinXP SP2 clients: the speed is varying,  
 but is about 1-2Mb/s at best.
 
 I spent quite some time investigating the issue, here are the  
 intermediate results:
 
 1) This happens only when transferring _from_ _Samba_ to _WinXP_.
 
 All other combinations are unaffected:
 
   a) Transferring from WinXP to Samba server is at 10Mb/s.
 
   b) Transfering to/from Samba server from Gentoo Linux on the same PC  
 where WinXP is installed (so, completely the same hardware and  
 connection) is also at normal speed.
 
   c) Transferring to/from WinXP to the server where Samba is installed  
 using any other protocol (such as HTTPS or SCP) is also at normal speed.
 
 2) CPU is at almost idle level both at client and server, so it's not  
 the issue.
 
 3) If there is any other network activity, transfer speed is increased  
 up to normal level: f.e. doing two simulteneous transfers from Samba  
 server to WinXP client gives 5Mb/s at each transfer, as expected.
 
 4) Running tcpdump on server while the transfer is performed improves  
 transfer speed in about 1.5 - 3 times, but still not to the normal  
 speed.
 
 5) Playing with socket options does not give any results.
 
 Specifically, using advices from the article  
 http://www.dd.iij4u.or.jp/~okuyamak/Documents/tuning.english.html  
 about SO_SNDBUF does not improve situation (but read below).
 
 6) tcpdump + tcptrace show that there are a lot of retransmissions,  
 see dumps below.
 
 7) I've tested several WinXP clients with different hardware, all with  
 the same results.
 
 8) Samba logs looks normal to me, nothing special.
 
 Points (3) and (5), and also the article about SO_SNDBUF tuning gave  
 me an idea that there might be smth wrong with ACKs sent from WinXP.
 
 I've tried to search for problems with ACK delays in WinXP and found  
 the following articles:
 
 http://support.microsoft.com/kb/328890
 http://support.microsoft.com/kb/321098
 
 Based on them, I've done the following changes in WinXP registry:
 
   - set TcpAckFrequency to 1 to switch off delayed ACKs
   - set TcpDelAckTicks to 0 to disable delayed ACKs timer
 
 These changes did not help on their own. But combining them with the  
 change of SO_SNDBUF to 1500 suddenly improved the speeds up to about 6  
 Mb/s!
 
 It appeared that with these registry changes, setting SO_SNDBUF to any  
 value in the range 1404 - 1872 gives the same speed of 6.0 - 6.4 Mb/s,  
 while changing it even one byte lower / higher immmediately drops the  
 speed to less than 1Mb/s.
 
 However, while this is partial solution I could live with, this is  
 still not the normal speed, so I still would like to find the way to

I would do extensive testing with IMAP and outlook before you put this
in to place, as Outlook support for IMAP is terrible, especially if you
want to have any remote users. If you are using any other mail
client you will be ok.

That is for a different mailing list though!

Thanks for your suggestion. Some of us are using Thunderbird, but the 
majority uses Outlook 2000. Thundrebird is unfortunately lacking some 
features of Outlook that would make some of the employees unhappy so the 
switch would not be without problems, but that's another story, and I 
think I'd better quit as we're already way too off-topic :-)

Did you have some PC-freeze problems that the reset on zero vc 
config parameter solved ?
We didn't have problems with freezing, we had problems with the network. 
It had the same effect, the client disconnected, the server thought it 
was still there.



Did the use of this parameter have some drawbacks ?
It hasn't caused any problems that I'm aware of and it has reduced the 
number of support calls, but I wouldn't consider it an alternative to 
fixing the root of the problem.


I believe it does cause problems if you have multiple connections coming 
into the server from behind a NAT connection and it may also play up if 
you have a terminal server.


We don't have neither of the two, so I guess I'll be safe :-)



Overall I think it is a neat option and in most simple networks it is 
worth having, just be wary that it may hide problems that will bite you 
down the track.

Obviously there is something causing the problem in the first place and 
you should try to track down what the problem is and fix it, in the mean 
time reset on zero vc might help make it more manageable.

sorts of problems with reiserfs. Some years ago I had
frequent customer emergencies because highly loaded tdb
files on reiserfs got corrupted. This meant that Samba was
not functioning on these machines. Changing the file system
to ext2/3 solved those problems reliably. But I have not
heard about those problems for a while. Not sure if reiserfs
was fixed or people don't use it anymore :-)

But then last week I heard about the lost homedir, and this
just supported my decision to never use reiser anymore for
anything.

I've been using reiser3 at home and work with no problem at all for 
almost 3 years now...


I can only say what *I* have experienced. I do not give a
firm recommendation either way. It's just that I will not
touch reiserfs anymore.

I have certainly also talked to a lot of people who are big
fans of reiserfs, so it's really your choice.

Volker


I admit the machines where I put reser3 were not under extremely high 
load, so it's certainly possible that particular workloads stress 
reiser3 in ways that corrupt the filesystem. I simply didn't see this.


So I guess our experiences just differ :-)

Thanks for clarifiyng your initial statement.

Great - thanks for the info. You might want to try

I'm trying to decide on a linux distro to use for our enterprise Samba

automatic updates for bugfixes and security (not to concerned about new

James Dinkel




We are using Gentoo Linux on a custom made P-IV-based raid1 scsi box.

Currently, gentoo offers 3.0.22-r3

Gentoo portage is technically very different from rpm, but once you get 
used to it, it's just as simple (IMHO even simpler wrt package 
dependencies).


It basically comes down to:

emerge --sync   # to get the latest version
emerge samba# dowload, compile and install
rc-update add samba default # start samba at boot

Configuration is just standard smb.conf editing (or webmin, if installed).

Just my 2 (euro)cents.

[Samba] oplocks causing more trouble than benefit ?

2006-11-03 Thread Marcello Romani

Hi everybody,
my setup is 1 fileserver running samba 3.0.22 on Gentoo Linux, and 
about 15 clients, some of which are XP and some W2K.


On some PCs we have Outlook 2000, and we store each user's outlook.pst 
file in a private folder on the fileserver.


One of the W2K clients had hardware problems that caused it to freeze 
once in a while.
Everytime this happened, the user would restart the machine and 
everything was fine except Outlook complained it could not open the 
personal folders file because it was already in use by another user (or 
process, I don't remember the error message exactly).


smbstatus showed in fact that the smbd process the user was connected to 
_before_ her PC freezed was still holding a DENY_WRITE lock on the 
outlook.pst file.


One solution was to manually kill that smbd process. While this worked 
almost every time (although it was really annoying because that PC's 
hardware failures were becoming frequent), one day I had to restart smbd 
entirely (or was it the entire server ?).


To make a long story short, I searched the docs and finally found that 
the problem was I had oplocks enabled in the smb.conf file. Disabling it 
solved the issue entirely.

The conf file now reads something like:

[NetworkDrive]
(snip other options)
oplocks = no


While trying to solve this issue I've read quite some docs about the 
oplocks feature, and I got the impression that while they may improve 
performance, they are very complicated and rely on a not so robust 
mechanism.
I didn't notice any slowdown after disabling oplocks, but this might be 
because our network and fileserver are underloaded.


So my question is: why are oplocks on by default ? Wouldn't it be safer 
to turn them off by default and specify under which circumstances they 
might give the performance improvements that justify their adoption ?


Thanks in advance.
