Samba搭建实现简单功能

                      Samba实验
  建立samba共享，共享目录为/test，要求：
  1、共享名为shared，工作组为magedu
  2、添加组develop，添加用户gentoo,centos和ubuntu，其中gentoo和centos以develop为附加组，Ubuntu不属于develop组，密码均为用户名
  3、添加samba用户，gentoo，centos和ubuntu密码均为“magedu”
  4、此samba共享shared仅允许develop组具有写权限，其他用户只能以只读方式访问
  5、此samba共享服务仅允许来自于172.16.0.0/16网络的主机访问
  [iyunv@localhost ~]# yum install samba
  [iyunv@localhost ~]# mkdir /test
  [iyunv@localhost ~]# groupadd develop
  [iyunv@localhost ~]# groupadd develop
  [iyunv@localhost ~]# useradd -G develop gentoo
  [iyunv@localhost ~]# useradd -G develop centos
  [iyunv@localhost ~]# useradd ubuntu
  [iyunv@localhost ~]# smbpasswd -a gentoo
  New SMB password:
  Retype new SMB password:
  Added user gentoo.
  [iyunv@localhost ~]# smbpasswd -a centos
  New SMB password:
  Retype new SMB password:
  Added user centos.
  [iyunv@localhost ~]# smbpasswd -a ubuntu
  New SMB password:
  Retype new SMB password:
  Added user ubuntu.
  修改/etc/samba/smb.conf，[global]中修改工作组
  workgroup = magedu
  [sharedddddd]
  comment = shared test
  path = /test
  browseable = yes
  writeable = yes
  write list = +develop
  allow hosts = 172.20.0.0/16
  [iyunv@localhost ~]# testparm
  Load smb config files from /etc/samba/smb.conf
  rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
  Processing section "[sharedddddd]"
  Loaded services file OK.
  Server role: ROLE_STANDALONE

  [global]
  workgroup = MAGEDU
  client signing = required
  idmap config * : backend = tdb
  [sharedddddd]
  comment = shared test
  path = /test
  write list = +develop
  read only = No
  hosts allow = 172.20.0.0/16
  [iyunv@localhost ~]# ll -d /test
  drwxr-xr-x 2 root root 4096 Aug 13 14:49 /test
  [iyunv@localhost ~]# chown :develop /test/
  [iyunv@localhost ~]# chmod g+w /test/
  [iyunv@localhost ~]# ll -d /test/
  drwxrwxr-x 2 root develop 4096 Aug 13 14:49 /test/
  验证，使用gentoo和centos登录可以创建文件，使用Ubuntu不能创建
