NSA 325 v2 unable to delete file

sniktaw

As the title suggests I'm unable to delete some files (through Windows File Explorer, Web Interface or SSH).

Files I can delete have Admin as the owner with permissions rwxrwxrwx

Files I cannot delete have 10018 as the owner with permissions rwxr-sr-x

I am unable to change the permissions.

Any ideas how to resolve this?

Thanks,

Darren

That is a strange list of attributes, rwxr-sr-x. The set-group-ID bit is set, which means it set the process’s effective group ID to that of the file, when executed. If the group is root, or 0 (zero), then maybe it's malware?

Anyway, the ability to delete a file is not a consequence of the file attributes, but of the directory attributes. I think you have no write access for that directory, maybe because it's 'w' bit isn't set.

Thanks for the quick response. Can you recommend the best way to edit permissions please?
the folder structure is: NFS\ABC\DEF\GHI\file.jpg
I can delete other folders from folder ABC but cannot delete folder DEF or the file.jpg
I cannot change the permissions, in Windows 10 file explorer, of folder DEF or GHI. Error: Failed to enumerate objects in the container. Access is denied.
Thank you, again.

Is it possible that the other, deleteable directories in ABC were empty? You can't delete a not-empty directory, so when a directory contains a non-deleteable file, you can't delete it, although you have the right permissions.

In this case I'd login over ssh, and execute:

cd /path/to/ABC
su
chmod -R a+w DEF

to give everybody write access to every file in DEF. If you don't know where ABC is located, execute

cat /etc/exports

to see the location of all NFS exports.

But maybe you should first execute 'dmesg', to see if there is a filesystem corruption.

Deleteable directories in ABC not empty.

Changed permissions as suggeseted and great, that worked. Thank you so much.
