===== Creating Recycle Bin for Samba storage =====
The best option is to have a "Recycle bin" for every users on the samba server.
Here is an example of modifying the home directories of your users in samba configuration file
[homes]
comment = Home Directory
valid users = %S
browsable = no
guest ok = no
read only = no
vfs object = recycle
recycle:repository = RecycleBin
recycle:keeptree = yes
recycle:exclude = *.tmp, *.bak
The “vfs object” line calls in the plug-in that enables recycle bin capability. On the other lines, you’re setting the name of the recycle bin directory, telling Samba to preserve the whole structure of any directories that a user may delete, and finally, telling it to not keep certain types of files.
==== newer version ====
If the required version of Samba is not installed, there are articles on how to update/install the correct version of Samba.
To implement the network recycle folder Samba uses a Virtual File System (VFS) module. The various VFS modules that Samba can use are in the local directory: //usr/lib/samba/vfs
Documentation on the options for the recycle.so module and other VFS modules can be found in the local directory //usr/share/doc/samba-x.x/docs/Samba-HOWTO-collection.pdf under chapter 19 or on the following website: http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/VFS.html
To implement a Samba recycle folder simply edit one of your shares to be similar to the example below:
**''/etc/samba/smb.conf''**
#============================ Share Definitions ==============================
[SambaShare]
path = /home/scripts
public = yes
writable = yes
browsable = yes
vfs object = recycle
recycle:repository = .deleted/%U
recycle:keeptree = Yes
recycle:touch = Yes
recycle:versions = Yes
recycle:maxsize = 0
recycle:exclude = *.tmp
recycle:exclude_dir = /tmp
recycle:noversions = *.doc
This configuration only implements a recycle folder on the directory "Samba Share". The above options must be specified for each Samba share you want the recycle folder functionality on.
The most interesting option above is:
recycle:repository = .deleted/%U
This specifies where the deleted files will be stored. This is relative to the share path. From the above example "Samba Share" has the path /home/scripts. Therefore anything that is deleted is moved to the directory .deleted under this path. The %U variable is the username of the person currently browsing the share. So for every user that deletes a file there is a directory with their username containing all the files they have deleted.
For example:
Scott is browsing the "Samba Share" directory and deletes a file. The deleted file can now be found under /home/scripts/.deleted/Scott \\
Brad is browsing the "Samba Share" directory and deletes a file. The deleted file can now be found under /home/scripts/.deleted/Brad \\
It is important to note that the .deleted directory must be created prior to use. It must then allow users to write to that directory. This is just an example and can be setup differently to suit your particular situation.
==== How can I list the currently active clients? ====
The winbindd deamon can log its status to the winbind log file upon request using the signal USR2.
If debuglevel is set to 2 or above, the windbindd dameon will also print the list of clients currently active.
# killall -USR2 winbindd
The winbind log level can be set separately in the smb.conf (/etc/samba/smb.conf) file using the "log level" option, for example:
log level = 2 winbind:3
**Reload the configuration in winbind by either sending a HUP signal to the winbindd daemon or by using "service winbind reload"**
# service winbind reload
===== samba + Windows Vista =====
Microsoft's security policy on WIndwos Vista is interestingly set by default to exclude mapping to Samba shares. To fix this click **START | Run | secpol.msc**. Go to Local Policies | Security Options and find Network Security: LAN Manager authentication level \\
Change the settings from Send NTLMv2 response only to Send LM & NTLM - use NTLMv2 session security if negotiated.
Vista defaults to only send the more secure NTLMv2 protocol, which Samba (and, incidentally, some NAS devices) do not support.
