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.
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
# service winbind reload
samba + Windows Vista
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.
