Howto: SSH access without password
See this howto to get access to your shell (over SSL) without a password. This howto generates a certificate which is imported at both local and remote profile.

Howto: SSH login without password
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]
SSH Tunneling on XP
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:
- Click Start, and then click Control Panel.
- If you are in Classic view, click Switch to Category View under Control Panel in the left pane.
- Double-click Printers and Other Hardware, and then click Next.
- Under See Also in the left pane, click Add Hardware,and then click Next.
- Click Yes, I have already connected the hardware, and then click Next.
- At the bottom of the list, click Add a new hardware device, and then click Next.
- Click Install the hardware that I manually select from a list, and then click Next.
- Click Network adapters, and then click Next.
- In the Manufacturer box, click Microsoft.
- In the Network Adapter box, click Microsoft Loopback Adapter, and then clickNext.
- 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
- Open Start, Control Panel, Add Hardware.
- Click Next on the introduction dialog box.
- Select ‘Yes, I have already connected the hardware’ and click Next.
- Scroll to the bottom of the list of hardware, select ‘Add a new hardware device’, then click Next.
- Select ‘Install the hardware that I manually select from a list (Advanced)’, then click Next.
- Select ‘Network adapters’, then click Next.
- Select ‘Microsoft’ as the manufacturer, select ‘Microsoft Loopback Adapter’ as the adapter, then click Next.
- Click Next to confim the installation.
- Click Finish to complete the installation.
- Open Start, Control Panel, Network Connections.
- Select the newly created connection (should be named ‘Local Area Connection N’, where N is its order number).
- Right click on the selected connection and choose Properties from the menu.
- Confirm that ‘Microsoft Loopback Adapter’ (or ‘Microsoft Loopback Adapter #N’) is displayed in the ‘Connect Using:’ field. If it isn’t, return to step 2 and retry properties for another adapter.
- Uncheck (disable) everything except ‘Internet Protocol (TCP/IP)’.
- Select ‘Internet Protocol (TCP/IP)’, then click Properties to open ‘Internet Protocol (TCP/IP) Properties’.
- Select ‘Use the following IP address:’ and fill in the ‘IP address:’ and ‘Subnet mask:’ fields (e.g. 10.10.10.10, 255.255.255.0).
- Click Advanced to open ‘Advanced TCP/IP Settings’.
- Switch to WINS and select ‘Disable NetBIOS over TCP/IP’.
- Click OK to close ‘Advanced TCP/IP Settings’.
- Click OK to close the ‘Internet Protocol (TCP/IP) Properties’.
- Optionally (on XP only) uncheck (disable) ‘Notify me when this connection has limited or no conectivity’ to remove the connection warning icon from the system notification area.
- Click OK to close the connection properties.
