[Bug 124795] Re: Cannot utime: Operation not permitted
I had similiar behaviour on my system (details were described in other bug discussion: https://bugs.launchpad.net/bzr/+bug/190725/comments/19 ). My suggestion is that error message in such case should be more usefull (I know that operation was not permitted, but I don't know what operation, why, what to search in google, how to fix etc). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/124795 Title: Cannot utime: Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntfs-3g/+bug/124795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 124795] Re: Cannot utime: Operation not permitted
I don't know how far is ntfs-3g privileges system integrated with kernel or FUSE, but if it is possible to add ntfs-3g option for allowing modification of access and modification times to every user who has write access would be very useful. This is not the first time I encounter this problem. e.g. CodeBlocks return an error during file save on ntfs partition.(I know CB should not change these times but for unknown reason it tries) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/124795 Title: Cannot utime: Operation not permitted -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 124795] Re: Cannot utime: Operation not permitted
I've seen that the manual says that the default security is that files and directories are created with the effective user and group of the mounting process, and have full access for everyone. I used the guid and umask options to change the security to have full access only for owner and group. I changed this because it is not acceptable that everyone has full permissions. but I cannot understand why tar gives errors... If I have write permissions on a folder, shouldn't I be able to create and delete files on it? Why should I be the same user of who mounts the ntfs partition? I created a folder in an ext3 partition with the same permissions (755) and tar does not print errors... drwxrwx--- 1 root ntfs 4096 2007-07-08 23:52 Dati (ntfs-3g) drwxrwx--- 3 root ntfs 4096 2007-07-09 09:43 test (ext3) What am I missing? This behavior is limiting as I can use the ntfs partition as /home (and I think also /, even if I would never do it) only without restricting the default permissions Thank you -- Cannot utime: Operation not permitted https://bugs.launchpad.net/bugs/124795 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If I have write permissions on a folder, shouldn't I be able to create and delete files on it? You can create and delete files but you can't update the timestamps as your error message says. From the utimes manual: Changing time stamps is permitted when: either the process has appropriate privileges (Linux: has the CAP_FOWNER capability), or the effective user ID equals the user ID of the file, or buf must is NULL and the process has write permission to the file. You're trying to change the timestamp as you/ntfs user/group , so you're not entitled to do so. The check is done by the kernel and it's correct. If you want to be able to change the timestamps then use the 'uid' mount option. Why should I be the same user of who mounts the ntfs partition? Because nobody implemented full multi-user support with full access right handling for NTFS yet. So either the above or full access for everybody are the current choices at the moment. -- Cannot utime: Operation not permitted https://bugs.launchpad.net/bugs/124795 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 124795] Re: Cannot utime: Operation not permitted
Ok I've understood that the difference between the ext3 try and the ntfs try is that in ntfs the user of created files is not me, while in ext3 is me. Thank you! I cannot mount the partition and change the uid to me because I'm in a multiuser environment, and so the other users would get the errors anyway. I will change the bug into: full multi user support not implemented yet in ntfs-3g. And I also think that this feature is a must to let ntfs-3g be used as a partition different by a share between windows/linux. Is there any implementation plan? or is it left for a far future?

[Bug 124795] Re: Cannot utime: Operation not permitted
See the 'Access handling, security' section in the ntfs-3g manual (type: man ntfs-3g). You either must be the same user as ntfs-3g is running or not use any access handling mount options (no uid, gid, umask, dmask, fmask). This is not a bug, the behavior is as it was designed and documented. -- Cannot utime: Operation not permitted https://bugs.launchpad.net/bugs/124795 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
