sudo apt install samba samba-common
sudo service smbd start
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
sudo vim /etc/samba/smb.conf
直接修改配置文件，去掉对应的注释就好。
直接在配置文件最后添加下面内容,即可共享/home/share。
[share]
comment = Share Folder require password
browseable = yes
path = /home/share
create mask = 0777
directory mask = 0777
valid users = share
public = yes
writable = yes
available = yes
然后需要在 Ubuntu上添加用户 share。
sudo adduser share
添加samba用户
sudo smbpasswd - a share
添加Samba用户sand并设置密码
sudo smbpasswd -a sand
# 接着输入密码
sudo service smbd restart
