Navigation as ftp

smbmount

Mounts the remote shares on the local files system

nmblookup

Gets an IP address from a NetBIOS name.

Server configuration

Server configurationConfiguration of Samba

Only one configuration file for the server.

Sections

[global]: general configuration options of the server

[homes]: options concerning the sharing of the personal directories.

[netlogon]: options concerning the management of netlogon (scripts).

[printer]:options concerning the sharing of printers

[share]: here, “share” indicates a specific shared folder.

Server configurationConfiguration of Samba

Variable substitutions

Allow to specify a variable instead of a name for a directive. These are some :

%U : The session username.

%G : The Primary group of %U

%h : The Server’s hostname

%I : The IP address of the client

%T : The current date and time

%s : The connected user

Server configurationConfiguration of Samba

[global] section Allows to configure environment parameters for the

server. Some basis parameters:

Workgroup netbios name Invalid users Hosts deny/allow guest account

Allows to activate the WINS server: name resolve order = wins host lmhosts bcast wins support = yes

Server configurationConfiguration of Samba

[global] section

Security options allow to specify how the security is managed:

user: Authentication on the server in order to list the shares and to have access on them.

share: Authentication is done on each shared folder. The listing is made without logging.

server or domain: Allows an authentication on another domain or server.

[share] section:

Each shared folder needs his section.

Share sections parameters:

comment: shared folder description.

path: path to the local folder.

valid users: list of authorized users

- user1, user2 : access for user1 and user2 only.

- @users: access for the group “users” only.

browseable: possibility to explore the shared folder

read only: access in read only mode.
