2.2.2.1 Getting and installing SSH for Windows 95, 98 and NT systems

The Computer Sciences Department has contributed to a UW-Madison site license for SecureCRT, a commercial implementation of the SSH client for the Windows 95, 98 and NT operating systems.

• You can download SecureCRT from http://shelf.doit.wisc.edu/securecrt/.
• SecureCRT will be including in future versions of the campus WiscWorld software package.

2.2.2.2 Establishing a secure session (SSH) using secureCRT on my home Windows computer

Start the secureCRT application. To create an entry for a host to connect to, complete the following steps:

1. Click on File | Connect. This will bring up the Connect dialog box.
2. Click on the New button.
3. Fill in the following fields:
   • Name: whatever name you want to call the session; for example ConnectNova
   • Protocol: ssh
   • DO NOT check connect via firewall
   • Hostname or IP: whatever host you would like to connect to; for example best-nova.cs.wisc.edu
   • Port: 22
   • User name: your username
   • Cipher: 3DES
   • Authentication: Password
   • Password: we recommend you leave this field blank and enter your system password when prompted.

If you've already created a session instance, you can simply edit the connection preferences by highlighting the appropriate session name and clicking on the edit button.

Note: Users can use any remote host which they are authorized to log into.

2.2.2.3 Transferring files from my home Windows workstation to my CS account

You *MUST* use SSH port forwarding. See the information on Establishing a secure session (SSH) using secureCRT on my home Windows computer

• To set-up SecureCRT for secure FTP
  
  
  1. Setup a secure connection for route66.cs.wisc.edu.
  2. In the Connect dialog box, highlight the route66 session you just created, and click on edit.
  3. In the Session Preferences dialog and click on the Advanced button on the Session tab.
     Select the Port Forwarding tab.
  4. To add a new forwarded port, click on New. Fill in the following fields
     • Local port: 21
     • Remote hostname: route66.cs.wisc.edu
     • Remote port: 21
  5. Click on OK in the Advanced SSH Options dialog, OK in the Session Preferences dialog, and OK in the Connect dialog.
     This should establish a connection to route66 using port forwarding. If this does not establish a connection, please check your steps and try again.
  6. Once the port forwarding has been established, any FTP application can now be used to securely transport files. Given below are examples of how to setup three of the many FTP clients that are available.
  
  
• To use WS_FTP (comes with WiscWorld) to transfer files:
  Start the application. The Session Properties dialog appears. If it does not open, clicking on the Connect button in the main application window will also open it. Fill in the follwing information:
  
  
  On the General tab
  • Profile name: whatever you want to call the session, for example SecureFTP
  • Host Name/Address: localhost
  • Host Type: Automatic detect
  • User name: your username
  • Password: we recommend you leave this field blank and enter your system password when prompted.
  • Account: leave blank
  • Comment: any additional notes you would like to make about the setup (for your personal reference only).
    
    On the Advanced tab
  • Check the Passive tranfers box
  
  
• To use Netscape to transfer files (download ONLY):
  • In the Location field type in the URL ftp://username@localhost:21/
    where username is your username.
  
  

• To use ftp from the DOS prompt:

  • U:\> ftp localhost

2.2.2.4 Reading POP mail from my home Windows workstation using SSH

To securely read your mail from a POP server, use SSH port forwarding to establish a secure POP session.

To establish a secure session to the CS Department POP server (pop.cs.wisc.edu):

1. Configure SSH (SecureCRT) port forwarding using the following configuration:
   • local port=110
   • remote hostname=pop.cs.wisc.edu
   • remote port=21
2. establish an SSH session to route66.cs.wisc.edu
3. Configure your POP mail client to use localhost instead of pop.cs.wisc.edu as the POP server.
   In Eudora, this is done in the Tools  | Options  | Checking Mail menu, setting POP ACCOUNT to username@localhost.
   (username is your login name).

To establish a secure session to a CS Department POP server other than pop.cs.wisc.edu:

1. Configure SSH (SecureCRT) port forwarding using the following configuration:
   • local port=110
   • remote hostname= remote.cs.wisc.edu
   • remote port=21
   remote.cs.wisc.edu is the hostname of as the POP server.
   In Eudora, this is done in the Tools  | Options  | Checking Mail menu, setting POP ACCOUNT to username@localhost.
   (username is your login name).
