CFS(Common File System)


33/52

CFS Three ways to access

World Wide Web (WWW)

Secure File Transfer Protocol (SFTP)

Network drive mapping (this is what wewill do)


34/52

CFS WWW Interface

Via WWW interface

http://cfs.iu.edu/username

Replace username with your username

Drag and drop not possible
http://cfs.iu.edu/usernamehttp://cfs.iu.edu/username


35/52

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
http://iuware.indiana.edu/http://iuware.indiana.edu/

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
http://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/usernamehttp://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/usernamehttp://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/usernamehttp://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/usernamehttp://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/usernamehttp://localhost/var/www/apps/conversion/tmp/scratch_8//cfs.iu.edu/username


37/52

CFS Details

You have just created a network drivemapping

In that mapping, youll see a folder called

1day-backup, which is a folder thatcontains the files that were backed up aday ago (in case you delete somethingimportant)

Do not mess with your 1day-backupfolder!

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.


43/52

Steel(a web server)


44/52

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 withour username and password

We will create a www folder as your web root

Whatever you put in there will be visible at yourhttp://mypage.iu.edu/~username/ address
http://mypage.iu.edu/~username/http://mypage.iu.edu/~username/


45/52

Steel SFTP

Open the Secure File Transfer Protocol(SFTP) client

Enter steel.ucs.indiana.edu as the host

Enter your username. Click connectEnter you password when prompted

When it logs you in, youll need to create a

www folder. Right click in the whitespace in the right pane and click NewFolder. Name it www.


46/52

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 yourwww folder visible


47/52

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


48/52

CFS and Steel machines

The CFS machine a seven IBM server

cluster

The Steel machine a nine Sun Solaris

server cluster
