This option usually must be set to “Yes” only on one Samba server for all other samba server on the same network and workgroup. local master = Yes This option “local master” allows “nmbd” the Samba server daemon to try and become a local master browser on a subnet. Like the above, usually this option must be set to “Yes” only on one Samba server that act as a local master on a subnet for all the other Samba server on your network. preferred master = Yes This option “preferred master” specifies and controls if “nmbd” the Samba server daemon is a preferred master browser for its workgroup. Once again must usually be set to “Yes” on one server for all the other on your network. os level = 65 This option “os level” specifies by its value whether “nmbd” the Samba server daemon has a chance of becoming a local master browser  for the WORKGROUP in the local broadcast area. The number 65 will win against any NT Server. If you have a NT Server on your network and want to set your Linux Samba server to be and win NT server for becoming a local master browser for the workgroup in the local broadcast area then you must set the “os level” option to 65. Also this option must be set on one Linux Samba server and must be disable on all other Linux Samba server you may have on your network. dns proxy = No This option “dns proxy” if set to “Yes”  specifies that “nmbd” the Samba server daemon  when acting as a WINS server and finding that a Net BIOS name has not been registered, should treat the Net BIOS name word-for-word as a DNS name and do a lookup with the DNS server for that name on behalf of the name-querying client. Since we are not configured the Samba server for acting as a WINS server, we don’t need to set this option to “Yes”. Also setting this option to “Yes” will degrade your Samba performance. name resolve order = lmhosts host bcast This option “name resolve order”  specifies what naming services to use to resolve host names to IP addresses and in what order. The parameters we chose cause the local “lmhosts” file of samba to be examined first, followed by the others. bind interfaces only = True This option “bind interfaces only” if set to “True”, allows to limit what interfaces on a machine will serve “smb” requests. This is a security feature. The configuration option “interfaces = eth0 192.168.1.1” bellow complete this option. interfaces = eth0 192.168.1.1 This option “interfaces” allows you to override the default network interfaces list that Samba will use for browsing, name registration and other NBT traffic. By default Samba will query the kernel for the list of all active interfaces and use any interfaces except 127.0.0.1 that are broadcast capable. With this option, Samba will only listen on interface “eth0” on the IP address 192.168.1.1. This is a security feature and complete the above configuration option “bind interfaces only = True”. hosts deny = ALL This option “hosts deny” specifies the list of hosts that are NOT permitted access to Samba services unless the specific services have their own lists to override this one. For simplicity, we deny access to all hosts by default and allow specific hosts in the “hosts allow =” option bellow. hosts allow = 192.168.1.0/24 127.0.0.1
