 |
|
Hello
This is a weird one. I'm dealing with a Windows server via cygwin to rsync files to a remote gentoo server. For the most part, everything is working fine, but on occasion I'm seeing weird permission issues, and I can't wrap my head around what's wrong.
First off, here is the rsync command from the windows server:
| Code: | | C:\cygwin64\bin\rsync -e C:\cygwin64\bin\ssh -rltgouvD --exclude='RECYCLER' --exclude='System Volume Information' --delete '/cygdrive/f/' "backup@backupserver:/var/backup/acme/Acme\ Files/" > File.txt |
So the user on the gentoo server is 'backup'. Important to note.
Now, here is the error I'm receiving from the windows server (from the cygwin shell)...
| Code: |
rsync: recv_generator: mkdir "/var/backup/acme/Acme Files/Client Files/2017/17-24 Acme/QBA/7- Photos/Garage Concrete/October/20171012" failed: Permission denied (13)
*** Skipping any contents from this failed directory *** |
There are some other errors with other files - like..
| Code: | default_perms_for_dir: sys_acl_get_file(Client Files/2017/17-27 Acme/QBA/1- TEST/22 - Test package/S-3 Faucet Alternate, ACL_TYPE_DEFAULT): Permission denied, falling back on umask
rsync: mkstemp "/var/backup/acme/Acme Files/Client Files/2017/17-27 Acme/QBA/1- TEST/22 - Test package/S-3 Faucet Alternate/.4903sp.pdf.umkG5k" failed: Permission denied (13)
|
Now, let's look at the directory on the gentoo box...
| Code: | backupserver /var/backup/acme/Acme Files/Client Files/2017/17-24 Acme/QBA/7- Photos/Garage Concrete/October
ls -al
total 16
drwxr-xr-x 5 backup backup 152 Oct 26 2017 .
d---r-x--- 3 backup backup 72 Oct 13 2017 ..
drwxr-xr-x 2 backup backup 48 Jun 13 08:52 20171012
drwxr-xr-x 2 backup backup 48 Oct 19 2017 20171019
drwxr-xr-x 2 backup backup 48 Feb 7 16:51 Concrete
----r-x--- 1 backup backup 15360 Oct 26 2017 Thumbs.db
backupserver /var/backup/acme/Acme Files/Client Files/2017/17-24 Acme/QBA/7- Photos/Garage Concrete/October
ls -al 20171012
total 0
drwxr-xr-x 2 backup backup 48 Jun 13 08:52 .
drwxr-xr-x 5 backup backup 152 Oct 26 2017 .. |
As you can see.. 20171012 is owned by backup and there are no files there. Yet, it's able to write files into the /October directory. These are all created via rsync (I did not create these directories, etc).
Next, let's look at that directory/files on the windows server via cygwin..
| Code: | administrator@Acme /cygdrive/f/Client Files/2017/17-24 Acme/QBA/7- Photos/Garage Concrete/October
$ ls -al
total 16
d---rwx---+ 1 User1 Domain Users 0 Oct 26 2017 .
d---rwx---+ 1 User1 Domain Users 0 Oct 13 2017 ..
d---rwx---+ 1 User1 Domain Users 0 Oct 13 2017 20171012
d---rwx---+ 1 User1 Domain Users 0 Oct 19 2017 20171019
d---rwx---+ 1 User2 Domain Users 0 Feb 7 16:51 Concrete
----rwx---+ 1 User2 Domain Users 15360 Oct 26 2017 Thumbs.db
$ ls -1l 20171012
total 7020
d---rwx---+ 1 User1 Domain Users 0 Oct 13 2017 .
d---rwx---+ 1 User1 Domain Users 0 Oct 26 2017 ..
----rwx---+ 1 User1 Domain Users 7158184 Oct 12 2017 IMG_20171012_105628969.jpg
----rwx---+ 1 User1 Domain Users 26112 Feb 7 16:50 Thumbs.db |
All the files that are rsync'd to the gentoo server are a user in the Domain Users group.
Based on what I'm seeing.. backup is rsync'ing via SSH and writing to a backup owned directory.. not sure why the permission denied?
Any ideas?
As I mentioned, there are a ton of files that get there no problem.
Thanks!

I think your problem is the strange permissions on ... | Code: | $ mkdir test
$ cd test/
$ mkdir -m070 x
$ mkdir -m070 x/y
mkdir: cannot create directory 'x/y': Permission denied |
When the process uid and the directory owner uid match, the system uses the owner's permission bits, even if less precise bits (group or other) are more permissive.
If I am right, you need to figure out why the permissions are set to 050, fix it, and modify whatever set them that way so that it does not reapply them. The strange permissions might be a consequence of using rsync under Windows, which has a different ACL model. If so, you may need to instruct rsync to ignore the original permissions and use a value of your choosing. |

So I need to figure out the issue on the Windows server. What is the best to ignore original perms and use my values via rsync?
Thanks so much!
