...S X clients are taking a _long_ time to list long directories. One directory with 10K entries is taking 3-4 minutes to display the entries in Finder. I captured a few seconds worth of packets and noticed that it's doing three requests per file: 1. NTCreateAndX - just opens the file 2. Close 3. FIND_FIRST2 - to look for the resource fork The first two happen extremely fast, the 3rd one is the kicker. Samba is taking about 0.025 seconds to return a response to the client (usually no such file status). Multiple that by 10K requests and you have a few minutes on your hands. I'm guessing the proble...

Note that I have tracked down the issue to what I believe to be the root cause, and the root cause is NOT an issue in Samba, but an issue with Microsoft's SMB2/SMB3 client that uses completely inefficient SMB2_FIND_ID_BOTH_DIRECTORY_INFO requests in SMB2/3 as opposed to efficient FIND_FIRST2 requests in SMB1: The main parts of my analysis of the issue are contained here: https://lists.samba.org/archive/samba/2017-July/209749.html https://lists.samba.org/archive/samba/2017-July/209750.html https://lists.samba.org/archive/samba/2017-July/209751.html Just citing key findings for your r...

I'm not an expert on the SMB protocol but I've captured packet dumps from a fresh share mount and directory view from both the Windows NT4 client and the Mac OS X client and it looks to me like the NT4 client is doing the directory contents lookups with a single "FIND_FIRST2, \*" and a corresponding return packet from the server with the listing of the directory contents whereas the Mac OS X Finder client appears to be doing a FIND_FIRST2 call for every file, including metadata files, in the directory. This would seem to be supported by a strace of the smbd proces...

I'm working on an embedded system that will communicate with a Samba server, and I'm wondering if there's a way to do a simple directory listing. I used Wireshark to see what my Win2K computer does, and I see it's using FIND_FIRST2. This is fine, probably acceptable, but Samba returns a lot of information I do not need, such as file creation/access times. I just need filenames, and will only be reading from Samba. It ends up being more data to store in limited RAM and parse. Can NT_CREATE_ANDX be used to obtain a direct...

I can't open a file (on our samba server) using Actis, When I troubleshoot the problem using Wireshark, see SMB protocol using FIND_FIRST2 and filename using obscure Windows metacharacters, e.g. USAARG03V>>A.SWK , which gives STATUS_NO_SUCH_FILE (Samba is interpreting the name literally) But if the files are copied to a local drive Actis can find them. Thanks for your help.

Hi, We have been a samba shop since way back and have used DFS quit a lot the last years. When we went with security ads instead of domain our dfs died. We have tried 3.028(sun) in solaris wich we are leaving and 3.2.1 in linux, our migration target. For our 3.2.1 installation the config looks liket this and the problem manifests itself as a empty share. [Global] kernel oplocks = False oplocks
