You should try rsync instead of cp: rsync -avz linux_path /mnt/windows_share/
and crontab instead of the perl loop: crontab -e
and add the following line to it:
* * * * * rsync -avz linux_path /mnt/windows_share/
It's going to be executed every minute, and if that's an option in your case, it's more robust than the while loop.
QEMU's built-in Samba service
The not-functioning -net user,smb
option was caused by an incompatibility with newer Samba versions (>= 4). This is fixed in QEMU v2.2.0 and newer with these changes:
(Debian has backported the latter two patches to 2.1+dfsg-6 which is present in Jessie.)
Usage
You can export one folder as \\10.0.2.4\qemu
when using User networking:
qemu-system-x86_64 \
-net user,smb=/absolute/path/to/folder \
-net nic,model=virtio \
...
When QEMU is successfully started with these options, a new /tmp/qemu-smb.*-*/
directory will be created containing a smb.conf
. If you are fast enough, then this file could be modified to make paths read-only or export more folders.
Mode of operation
The samba daemon is executed whenever ports 139 or 445 get accessed over a "user" network. Communication happens via standard input/output/error of the smbd process. This is the reason why newer daemons failed, it would write its error message to the pipe instead of protocol messages.
Due to this method of operation, the daemon will not listen on host ports, and therefore will only be accessible to the guest. So other clients in the network and even local users cannot gain access to folders using this daemon.
Since QEMU v2.2.0 printer sharing is completely disabled through the samba configuration, so another worry is gone here.
The speed depends on the network adapter, so it is recommended to use the virtio netkvm
driver under Windows.
Also note that the daemon is executed by its absolute path (typically /usr/sbin/smbd
) as specified at compile time (using the --smbd
option). Whenever you need to try a new binary or interpose smbd
, you will need to modify the file at that path.
Other caveats
Executables (*.exe
) must be executable on the host (chmod +x FILE
) for the guest to have execute permissions. To allow execution of any file, add the acl allow execute always = True
option to a share.
Example read-only smb.conf configuration which allows execution of any file (based on QEMU v2.2.0):
...
[qemu]
path=/home/peter/windows
read only=yes
guest ok=true
force user=peter
acl allow execute always = True
Best Answer
From your UNIX server you need to
mount
the Windows share using the procedure laid out in this link.Basically you create a directory on your UNIX machine that is called the mount point. You then use the
mount
command to mount the Windows share on that mount point. Then when you go to the directory that you have created you see the files that are in the Windows share.
