Note: For Ubuntu 8.04 (Hardy) and later, shared directories are created directly from the directory. Browse to the location of the directory you would like to share, right-click the directory, and choose Sharing Options. Click the "Share this folder".

The shares are defined in the background using the "net usershare" command and the definitions are saved in /var/lib/samba/usershares/ . Therefore, shares defined with this method are not visible in smb.conf.

username map = /etc/samba/smbusers

log file = /var/log/samba/log.%m

Samba Server Configuration by GUI

For Gnome, the package system-config-samba is convenient. Once installed, launch System - Administration - Samba. (Shares created using the "Sharing options" context menu will not be visible in this tool.)  Or launch it by searching samba in dashhome. 找到对应的leon用户，然后输入samba 用户名和密码并确定。

A less friendly but also graphical tool is , a web-based interface.
