mount CD/DVD.iso

sudo mount -t iso9660 -o loop /full/path/to_your_.iso /mnt

ls /mnt

The CD/DVD won't show on the desktop.

If you want it to appear on the desktop, then 

sudo mkdir /media/fakecd

sudo mount -t iso9660 -o loop /path/to/your.iso /media/fakecd

sudo umount /media/fakecd

開samba檔案共享

[資料夾的名稱]

sudo /etc/init.d/samba restart
Debian:

上面那個太權限太危險了，訪客都可以讀寫資料夾，下面這個比較安全

[folder name]
path=/home/superppp/abc
browseable = yes
read only = no
writable = yes
valid users = bill

重啟samba之後，新增samba使用者：

sudo smbpasswd -a bill

輸入兩次密碼後，就可以安全使用了。
