VirtualBox 上で CentOS や Ubuntu を起動させ、 Samba でファイル共有

Centos6の場合

sudo yum install -y samba
sudo chmod 755 /home/$USER
sudo smbpasswd -a $USER
sudo cp -a /etc/samba/smb.conf /etc/samba/smb.conf.org
sudo vi /etc/samba/smb.conf # 編集方法は以下参照
sudo /etc/rc.d/init.d/smb start
sudo /etc/rc.d/init.d/nmb start
sudo chkconfig smb on
sudo chkconfig nmb on
sudo setsebool -P samba_export_all_rw 1
sudo /etc/rc.d/init.d/iptables stop
sudo chkconfig iptables off
sudo chkconfig ip6tables off

CentOS7 の場合

sudo yum install -y samba
sudo chmod 755 /home/$USER
sudo smbpasswd -a $USER
sudo cp -a /etc/samba/smb.conf /etc/samba/smb.conf.org

ファイアウォールのポート開放

sudo ufw allow 137
sudo ufw allow 138
sudo ufw allow 139
sudo ufw allow 445

すべてのポートを空ける場合は以下

sudo ufw default ALLOW

Ubuntuからアクセスする方法（Ubuntuがクライアントの場合）

sudo apt-get install -y cifs-utils
sudo mkdir /mnt/XXX

※「XXX」は任意

マウント

sudo mount.cifs //AAA.AAA.AAA.AAA/BBB /mnt/XXX/ -o username=BBB,uid=$(id -u),gid=$(id -g)

AAA : サーバIP
BBB : サーバ側のユーザ名

アンマウント

sudo umount /mnt/XXX
