similar to: CIFS client mounts meta ops 30 times slow than server

Also from my observation, based on network packets and time measurements, it seems the CIFS clients haven't done any sort of cache. For example, doing a "ls" for 5 times on the same folder within a short period of time. The network packet sizes are almost equal every time and the time it takes is similar. Isn't there supposed to be some page cache or dentry cache that could

Hi Samba users, We would like to use samba for re-exporting our other distributed file system (BeeGFS). However, we found that the meta data operations are very slow (dir stat, removal etc.). On SMB client the performance is more than 30x slow than on the SMB server. We would expect some slowness but this is too big a drop. This is the result on CIFS client $ sudo mdtest -b 10 -I 10 -L -z 2

Dear Jeremy, thanks for your instant reply. :-) Along with Linux native getfacl/fetfacl, I also tested getcifsacl/setcifsacl (for sure thoroughly ;-)). Unfortunately, these CIFS client tools seem to have been designed as part of the "old" CIFS Unix Extensions, working only for SMB/CIFS mounts, and are not supposed to work with SMB2/SMB3 mounts, as I guess. During my tests, the

Windows ACLs map quite well into RichACLs. Unfortunately Christolph Hellwig has peristently blocked any merge of the RichACLs code into the Linux kernel. If you use ZFS then you can use ZFSACLs which are quivalent. >

Steve says there are two utilities in Linux, getcifsacl and setcifsacl that use a custom ioctl inside the Linux cifsfs kernel

Found some more info: mount.cifs to mount shares from my DCs (samba 4.2.11) works mount.cifs to mount shares from smbserver (also 4.2.11) does NOT work.

Thanks for the first reply, Jeremy. What about the (future) implementation of RichACL? Will there be any native Linux Client support along with the SMB2/SMB3 protocol? I know, there is a native implemenation for RichACLs in ext4 FS. Unfortunately, smbcals is not a native Linux ACL Tool and has a very unhandy syntax. I just tested some days ago. ;-) I am looking for a solution that allows the

Using samba 3.2.1, when trying to mount cifs mounts at boot from in the /etc/fstab, I get the following error in my syslog: CIFS VFS: cifs_mount failed w/return code = -22 After enabling debugging from the /proc interface, I get this: fs/cifs/cifsfs.c: Devname: //skuld.tolharadys.net/greeneg flags: 0 fs/cifs/connect.c: CIFS VFS: in cifs_mount as Xid: 10 with uid: 0 fs/cifs/connect.c:

Would be good to continue to encourage backports by the distros of recent kernel cifs, not just for encryption support, but also for SMB3 DFS support and various other features, and some very exciting patches are in progress for the upcoming kernels.

CIFS or SMB3 mount (vers=3.0)? I doubt that RHEL has backported the encryption feature in the kernel client yet, but would be a good question for RHEL support.

New version 6.10 of cifs-utils has been released. Highlighted changes: - smb3 alias/fstype is added - smb2-quota tool is added to display quota information - smb2-secdesc UI tool to view security descriptors is added - smbinfo is enhanced with capabilities to dump session keys and get/set compression of files - smbinfo bash completion is supported - getcifsacl tool is improved to support

Greetings, I am working on getting mount.cifs version: 1.11-3.2.4 on debian to mount a share on a samba server Version 3.0.13-1.1-SUSE on SuSe. This was working on older debian systems, but upon upgrading some of the systems to Lenny I am now having trouble mounting shares. Again, this was working and I have smbfs installed on the systems (which is what I used before). The samba server is set

Thanks Steve for Quick response!! *My question is*: => Accessing encrypted shares fully depends on kernel fix (as you provided), If no? => How can we use /etc/samba/smb.conf "smb encrypt = mandatory" parameter to access encrypted shares? Because using this parameter I am not able to access samba-shares either from windows/RHEL client Thanks Amit On 04/03/2017 11:48 AM,

Hai,   ( not all on samba topic but one i wanted to share. )   I did read :  https://wiki.samba.org/index.php/LinuxCIFSKernel mainly because of, from that page, 4.7 Kernel Fix badlock regression for guest mounts (mount with -o guest can fail to Samba servers when patched for badlock). I encountered such a problem yesterday. Luckly not in the office..   The fix. Cifs.ko version

I passed by the changelog for the Linux CIFS Kernel Module at https://wiki.samba.org/index.php/LinuxCIFSKernel. The following two sections caught my attention: >> 4.19 Kernel (69 changesets, module version 2.13) >>Allow cifs.ko to be built with insecure dialects disabled (vers=1.0 and vers=2.0 not allowed).

Hi, I just installed CIFS support on my machines and must say it works much better than smbfs. special characters alright, transfer speed doubled (from 2.8MB/s to 5.6MB/s on 100MBit). There's two issues tho I haven't been able to root out: -credentials file: tried username=<username> and password=<password> in /etc/credfile, tried user=<username> to match the

Hi, I'm trying to mount a Samba share on Linux 2.6.10, using samba-3.0.7. The authentication is done using Kerberos V5, on a Windows server. The share is located on a Solaris server that uses samba-3.0.10. Authentication with Kerberos is functional (I can get a ticket using kinit(1)). The server requires client (packet?) signing. The admins in charge of the server refuse to make it
