Tips on how to share Folder on Linux.

Note: to securely share a folder, you need have a account of that computer.

• right click on that folder, click “Property”
  • under “Sharing” tab
    • check “Share this folder”, (give a share name that appears on network)
    • Note: if you want to others who don't have a user account on this computer to access this shared folder
      • check “Guest access”, if you want other to modify, then check “Allow others to create”
• To access the share folder from other computer under same local network,
  • (Windows) press “Windows key + R”, then type "\\the_computer_name_or_ip\shareFolderName"
  • (Mac) go to Finder > Go menu > Connect to Server > at the dialog, enter "smb://the_computer_name_or_ip/shareFolderName"
  • (Linux - Ubuntu) Places menu > Connect to Server, choose “Windows Share”, type ip address, connect

FAQ:

• You may receive a message which says Sharing services are not installed. If this happens, ensure that the two checkboxes in the message box are checked and press Install services. Sharing service support will then be downloaded and installed; this may take a while.

• “Enter password to unlock your login keyring” prompt after automatic login and get rid of it for auto connect secured wireless point on boot
  1. Keyring is Gnome's password management tool, like Mac OS X's keychain or Firefox password remember function
  2. (since you choose automatic login, secure is not a problem) then choose no master password for your keyring, (default is your login password)
  3. to remove the keyring password, just go to System/Preferences/Passwords and Encryption Keys, right-click the “Passwords:login”-keyring and select “Change Password”, to a blank password

• DiskInternals Linux Reader: reader for Ext2/3/4, HFS format disk
• Ext2 IFS: reader and writer for Ext2/3 format disk
• Mediafour’s MacDrive: reader and writer for HFS format disk (not free)

Linux can natively read and write on NTFS, FAT format disk.
Mac can natively read NTFS, and read and write on FAT format disk.
Mac can use ntfs-3g tool to write on NTFS disk, but not recommended, as it's slow and unstable.
