32
CFS (Common File System)
33
CFS Three ways to access

• World Wide Web (WWW)
• Secure File Transfer Protocol (SFTP)
• Network drive mapping (this is what we will do)

34
CFS WWW Interface

• Via WWW interface http//cfs.iu.edu/username
• Replace username with your username
• Drag and drop not possible

35
CFS SFTP Method

• You need a Secure File Transfer Protocol client
• Two common examples MacSFTP (for Macintosh
  machines) and SSH Secure Shell (for Windows
  Machines)
• Download from IUware Online http//iuware.indiana
  .edu

36
CFS Mapping a drive

• Right click on My Computer and select Map
  Network Drive
• In the Drive field, choose Z (the choice is
  arbitrary, but we should be consistent)
• In the Path field, type the following
  \\cfs.iu.edu\username
• Click Finish
• A window will open showing you your files

37
CFS Details

• You have just created a network drive mapping
• In that mapping, youll see a folder called
  1day-backup, which is a folder that contains
  the files that were backed up a day ago (in case
  you delete something important)
• Do not mess with your 1day-backup folder!

38
File Management
39
File Management

• Creating a folder right click in white space
  and choose New then choose Folder. Type a
  name for the folder.
• Rename a folder right click on a folder, choose
  rename, and enter a new name.
• Entering a folder double click on it
• Getting out of a folder click on the up
  button in the toolbar

40
File Management

• Deleting files click on them, then push the
  delete key OR right click on them, then choose
  delete
• Deleting folders done the same way
• Where did these things go?
• The Recycle bin!

41
File Management Recycle Bin

• Located on the desktop
• Double click on it to enter it
• You can restore a file by right clicking on it
  and choosing Restore
• You can permanently delete it by right clicking
  on it and choosing Delete
• Emptying the Recycle bin (under File)
• Why is the Recycle bin good? Why is it bad?

42
CFS Unmapping our drive

• Used to log out of the drive
• Makes it so the machine cant be used to get at
  files
• Go to My Computer, right click, and choose
  Disconnect Network Drive
• Click on the Z drive. Choose OK.

43
Steel(a web server)
44
Steel A web server

• We use SFTP to access Steel
• The lab machines should have the Secure File
  Transfer Client and the Secure Shell Client.
• We will connect to steel.ucs.indiana.edu with
  our username and password
• We will create a www folder as your web root
• Whatever you put in there will be visible at your
  http//mypage.iu.edu/username/ address

45
Steel SFTP

• Open the Secure File Transfer Protocol (SFTP)
  client
• Enter steel.ucs.indiana.edu as the host
• Enter your username. Click connect
• Enter you password when prompted
• When it logs you in, youll need to create a
  www folder. Right click in the white space in
  the right pane and click New Folder. Name it
  www.

46
Steel SSH

• Open the Secure Shell client
• Enter steel.ucs.indiana.edu as the host
• Enter your username. Click connect
• Enter you password when prompted
• If asked about your shell preference, choose 5
  for bash. You will then be disconnected.
  Reconnect.
• Use the spinweb command to make your www folder
  visible

47
Arent CFS and Steel the same?

• Nope. They both let you store files, but they are
  distinct
• CFS lets you upload and download your files using
  www, SFTP, or drive mappings
• Steel only lets you use SFTP for transferring.
  But, Steel is a public web server and it lets you
  login to the shell

48
CFS and Steel machines

• The CFS machine a seven IBM server cluster
• The Steel machine a nine Sun Solaris server
  cluster
