Re: En passant ;-)

$ man smb.conf

 hosts allow (S)

 A synonym for this parameter is allow hosts.



 This parameter is a comma, space, or tab delimited set of hosts

 which are permitted to access a service.



 If specified in the [global] section then it will apply to all

 services, regardless of whether the individual service has a

 different setting.



 You can specify the hosts by name or IP number. For example, you

 could restrict access to only the hosts on a Class C subnet with

 something like allow hosts = 150.203.5. . The full syntax of the

 list is described in the man page hosts_access(5). Note that

 this man page may not be present on your system, so a brief

 description will be given here also.



 Note that the localhost address 127.0.0.1 will always be allowed

 access unless specifically denied by a hosts deny option.



 You can also specify hosts by network/netmask pairs and by net-

 group names if your system supports netgroups. The EXCEPT key-

 word can also be used to limit a wildcard list. The following

 examples may provide some help:



 Example 1: allow all IPs in 150.203.*.*; except one



 hosts allow = 150.203. EXCEPT 150.203.6.66



 Example 2: allow hosts that match the given network/netmask



 hosts allow = 150.203.15.0/255.255.255.0



 Example 3: allow a couple of hosts



 hosts allow = lapland, arvidsjaur



 Example 4: allow only hosts in NIS netgroup "foonet", but deny

 access from one particular host



 hosts allow = @foonet



 hosts deny = pirate



 Note



 Note that access still requires suitable user-level passwords.



 See testparm(1) for a way of testing your host access to see if it does

 what you expect.



 Default: hosts allow = # none (i.e., all hosts permitted access)



 Example: hosts allow = 150.203.5. myhost.mynet.edu.au
