This howto shows how to generate a certificate to achieve ssh login without password:

Step 1:

jsmith@local-host$ [Note: You are on local-host here]

jsmith@local-host$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jsmith/.ssh/id_rsa):[Enter key]
Enter passphrase (empty for no passphrase): [Press enter key]
Enter same passphrase again: [Pess enter key]
Your identification has been saved in /home/jsmith/.ssh/id_rsa.
Your public key has been saved in /home/jsmith/.ssh/id_rsa.pub.
The key fingerprint is:
33:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 jsmith@local-host

Step 2:

jsmith@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host
jsmith@remote-host's password:
Now try logging into the machine, with "ssh 'remote-host'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

Step 3:

jsmith@local-host$ ssh remote-host
Last login: Sun Nov 16 17:22:33 2008 from 192.168.1.2
[Note: SSH did not ask for password.]

jsmith@remote-host$ [Note: You are on remote-host here]
  




	

Bitvise Tunnelier is an excellent tool for SSH Tunneling and Terminal access over SSH. Tunnelier supplies a secure SSL connection to a SSH enabled system.

I personally use tunnelier to access my resources (shares, sites, proxy) at home fromout a secure tunnel which is setup to a SSH enabled machine. Tunnelier offers client-to-server forwarding which enables portmapping from your local machine to the remote machine.

For portmapping purposes i used the Microsoft Loopback Adapter with a specific (for me applicable) ip-address 1.2.3.4 .

Here’s a quick how to to get this solution working, download links are listed inside the how to.

1. Installing the Microsoft Loopback Adapter:

To manually install the Microsoft Loopback adapter in Windows XP, follow these steps:

1. Click Start, and then click Control Panel.
2. If you are in Classic view, click Switch to Category View under Control Panel in the left pane.
3. Double-click Printers and Other Hardware, and then click Next.
4. Under See Also in the left pane, click Add Hardware,and then click Next.
5. Click Yes, I have already connected the hardware, and then click Next.
6. At the bottom of the list, click Add a new hardware device, and then click Next.
7. Click Install the hardware that I manually select from a list, and then click Next.
8. Click Network adapters, and then click Next.
9. In the Manufacturer box, click Microsoft.
10. In the Network Adapter box, click Microsoft Loopback Adapter, and then clickNext.
11. Click Finish.

After the adapter is installed successfully, you can manually configure its options, as with any other adapter. If the TCP/IP properties are configured to use DHCP, the adapter will eventually use an autonet address (169.254.x.x/16) because the adapter is not actually connected to any physical media.

Note By default, TCP/IP properties are configured to use DHCP.

2. Configure the Microsoft Loopback Adapter for usage with Tunnelier
