Unfortunately I didn’t seem to have saved one of those big gencache.tdb files (we don’t currently see them). Or at least I can’t seem to find them now… A while ago when we first discovered this I posted a message: https://lists.samba.org/archive/samba/2017-December/212577.html <https://lists.samba.org/archive/samba/2017-December/212577.html> I now notice that I never replied to a

Is it normal that the gencache.tdb should grow and grow “forever” and fill up with “RA/<hex>” posts? I’ve been investigating why our Samba 4.7.3 servers (happened with older version 4 servers too) would use such insane amounts of memory on our FreeBSD 11.1 servers (we see smbd processes using hundreds of megabytes of RAM and up to 5GB virtual memory). Anyway, one part that seems to use

For what it’s worth you are not alone in seeing similar problems with Samba and gencache. Our site has some 110K users (university with staff & students (including former ones), and currently around 2000 active (SMB) clients connecting to 5 different Samba servers (around 400-500 clients per server). When we previously just let things “run” gencache.tdb would grow forever and authentication

I’m going to try to upgrade from 4.7.6 to 4.7.7 on one of our servers soon and see if things break or not. With 4.7.6 things are stable at least. Our file servers are in a Microsoft Windows domain (consisting of 6 Microsoft Windows 2016 AD servers). The graphs (logarithmic time scale) below are login times from a probe station that times a connect using “smbclient” with a Kerberos ticket and

Hi! Technical description below, but the exec summary is: Yes, we have a performance problem with gencache.

I am trying to determine which tdb files must be backed up in order to perform a proper system restore. I am running Centos's samba-4.9.1-6.el7.x86_64 as a PDC. There is a basic backup routine which backs up all files under /var/lib/samba but this appears to be wasteful, especially as gencache.tdb keeps growing until I delete. I can find a Samba3 reference at

Hi, I recently upgraded an older box running as a file server for a small company to Mandriva (Mandrake) 10.1. It's running Samba 3.0.10.1, the default Mandrake package. We have a custom script that mounts a Windows share using smbfs, backs up specific directories, and unmounts when it's done. The problem is, it's not mounting reliably. There is an entry in /etc/fstab for the

The config looks ok, thats great. :-) Its not needed to stop samba running : net cache flush If you run: net cache list and have a look, then flush it and look again. You see its empty. If you need to copy the idmap than it is needed to stop samba. Can you show me an output of. dpkg -l | egrep "tevent|tdb|ldb|talloc|cmocka" Im running latest versions of these. Own compile or

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:-

Dear all, The server log is filled with entries "xxx len xxxxx deyond eof at 8192" I have search on google but can't found a solution for it, please advise.

I run smbd 4.18.8 inside a docker container via "smbd --foreground" (see the attached config). Recently my server was abruptly restarted due to a power outage. Upon the restart it was able to successfully start the container, but the shares became inaccessible due to smbd rejecting all authentication attempts. In the logs I found: [2024/03/18 08:22:50.790021, 5]

Hi all, I've finally almost gotten my desired Samba+AD integration working: I've joined a domain, AD users can login, kerberos works (keytab integration, caching, etc.), etc. However, this is only true as long as I hack my /etc/hosts and /etc/samba/lmhosts files to trick Samba into always using my networks Windows 2000 Active Directory Server. The second a Samba command finds and

A little summary of building Samba 4.12.0rc3 on OmniOS: The following 4 (5) small patches are needed in order to compile and run Samba 4.12.0rc3 on the latest OmniOS r151032p (OpenSolaris/Illumos variant): 1. ARRAY_SIZE is already defined in <sys/sysmacros.h> on OmniOS, put an #ifndef around it in lib/replace/replace.h (can be ignored but causes a gazillion compiler warnings :-):

The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 2974 (/usr/sbin/smbd). This means there was a problem with the program, such as a segfault. Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred. The Samba log files may contain additional information about the problem. If the

Hi All, Firstly, I know this is a MacOS X issue and not sure if you guys can help, but I'm really hoping you can since I don't appear to be getting any joy elsewhere. Running OSX 10.5.4 and recently (last week) nmbd is hogging the CPU. I know this is a part of the Samba server on OSX, hence the post to this mail-list. When I disconnect from the network, nmbd goes away and doesn't

Hi all, I have a midsize AD domain with some 50k users but only 100 workstations joined. Sometimes I find server CPU throttling at 100%. In order to let it drop and have smooth performance I delete cache: systemctl stop samba net cache flush systemctl start samba First of all, is it needed a samba stop to flush the cache? Even if cache flush does the job to restore performance, I am clueless
