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
[root@localhost ~]# yum install samba
[root@localhost ~]# mkdir /test
[root@localhost ~]# groupadd develop
[root@localhost ~]# groupadd develop
[root@localhost ~]# useradd -G develop gentoo
[root@localhost ~]# useradd -G develop centos
[root@localhost ~]# useradd ubuntu
[root@localhost ~]# smbpasswd -a gentoo
New SMB password:
Retype new SMB password:
Added user gentoo.
[root@localhost ~]# smbpasswd -a centos
New SMB password:
Retype new SMB password:
Added user centos.
[root@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
[root@localhost ~]# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

idmap config * : backend = tdb
[sharedddddd]
comment = shared test
path = /test
write list = +develop
read only = No
hosts allow = 172.20.0.0/16
[root@localhost ~]# ll -d /test
drwxr-xr-x 2 root root 4096 Aug 13 14:49 /test
[root@localhost ~]# chown :develop /test/
[root@localhost ~]# chmod g+w /test/
[root@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
