Hi, Does someone know a document which explains the TDB structure. functionalites, and format of the TDB files etc. I need to understand why some of the TDBs like messages.tdb, unexpected.tdb, brlock if not read_only, locking.tdb, session.tdb, wins.tdb are called with TDB_CLEAR_IF_FIRST tdb flags. Why some TDBs are opend with O_RDWR|O_CREAT flags viz. gencache.tdb, group_mapping.tdb,

Hi! I've been fighting with Samba for over a week now and I can't seem to work it out. It all started when I installed the standard samba (2.2.1a-4) which came with RH7.2. I ran "smbstatus" and got the following error: Failed to open byte range locking database ERROR: Failed to initialise locking database Can't initialise locking module - exiting. I've tried the

In /varcache/samba/ I have several .tdb files. Like brlock.tdb, locking.tdb, ntdrivers.tdb, etc. Excusing my ignorance, what are these files, and what do they do? And why must they be copied when migrating from one samba server to a new one?

I'm running 2.11, and I've noticed a number of log entries that look like so: angie.log: tdb(/usr/local/samba/var/locks/locking.tdb): expand_file ftruncate to 8192 failed (Permission denied) [2004/10/03 15:14:36, 0] tdb/tdbutil.c:tdb_log(531) tdb(/usr/local/samba/var/locks/brlock.tdb): expand_file ftruncate to 8192 failed (Permission denied) The files in question look like this:

Hi all, i am trying to run Samba 2.2.3a under a RedHat 7.2 i386 machine. After i compiled and installed the packages, i made a smb.conf up. Just some standard stuff nothing special. Now, when i start smbd and then check it with smbstatus it gives me this error : Samba version 2.2.3a Service uid gid pid machine ---------------------------------------------- tdb((null)): tdb_open_ex: could not

(Yes, I should upgrade Samba to 3.0.35). We're running the Sun provided Samba daemon (SUNWsmbau and friends) on Solaris 10 Generic_138888-08 (sparc). Lots of Windows clients (mixed XP, 2003, 2008) hit this server and periodically we'll start seeing smbd processes begin piling up. These processes can't be killed with a normal kill -- only kill -9 will do the trick. In the past

I have successfully implemented Samba in the past but I am now perplexed by a new installation which fails smbstatus with the message: "tdb((null)): tdb_open_ex: could not open file /var/cache/samba/brlock.tdb: No such file or directory Failed to open byte range locking database "tdb((null)): tdb_open_ex: could not open file /var/cache/samba/locking.tdb: No such file or directory ERROR:

We've just gone live with a file & print server, and are having major problems with Samba. When used out of hours, with all PCs switched on and connected to the domain, everything works fine. However, during the day, we have problems where users can't print to any samba-hosted printer, Access database applications (where the database is held on the server) won't work, or work

Hello, I have been tracking this bug as much as possible, and it appears there is a severe problem in the code that deals with .tdb files. Lately our samba 2.2 testbed has been having painfully slow network responsiveness. It would go 30-60 seconds without a response to a client on many occasions (both browsing the network, and opening files/refreshing directories). Clients include Windows 98se,

i have taken a default intel redhat 7.2 machine which came with samba 2.2.1a and removed samba, samba-common, samba-client and samba-swat. i also removed /etc/samba and /var/lock/samba and all samba log files i then installed the samba RPM for samba 2.2.5 from: http://se.samba.org/samba/ftp/Binary_Packages/redhat/RPMS/7.2/samba-2.2.5- 1.i386.rpm i then installed this with rpm -ivh

i've been integrating a Samba server into a mixed windows 2000/2003 authentication environment for use as a NAS device. i finally have things working for the most part, but in the process of debugging authentication i noticed an error when performing the following command: hmason@mpinas1:~$ smbclient -L localhost the error shows up when loglevel = 5 in smb.conf: Netbios name list:-

I added LOG statements to mutex.c printing the strerror from the return values.   From   ret = pthread_mutexattr_init(&ma); in line 570   I got errorno 16 --> device busy.   But due the manual of pthread_mutex_attr_init() there should only be ENOMEM and EINVAL...   Doing gdb smbd -> run Doe not reveal anything, but I never used gdb for debugging anything. I just gave it a shot...        

Hi Slight problem - linux 2.4 running dovecot, Solaris 2.8 home directory server. Full lockd support etc. I had to make the following code patches (at end of mail for clarity) to get dovecot to read the users mbox files at all. 1) fcntl with F_SETLKW will not work against a Solaris 2.8 server as proved with a small test program. Other forms of fcntl (ie F_SETLK) are OK. I noticed there are

Hello, I've found this issue reported only once before but no real answer was provided/found. I am trying to migrate from an old 2.0.7 server, but the bundled install 3.0.24 on FC6 is giving me major pain. Putting aside the actual configuration and user migration which I need to figure out, the problem is that nmbd refuses to start with the following errors in the log: [2007/02/26 14:05:26,

Thanks very much, Volker. I want to synchronize three tdb files(listed as below) which is relevant to the opened file: 1) brlock.tdb 2) locking.tdb 3) smbXsrv_open_global.tdb These three tdb files are used to realize the durable file handle feature. As what you have said, the performance will be affected if storing these three files in the shared storage. So can I realize the synchronization

Version 2.0.5a (same prob w/2.0.4b, though). smbsh segfaults after I enter my password. As root, it just seg faults. As my login user, it dumps core. Attached is a script of an strace of it.
