<h1>Using an SSH agent to avoid typing your password</h1>
|
|
|
|
<!-- Somebody better at it should put a nice introductory paragraph here -->
|
|
<h3>Do not use this tutorial until you <a href="http://sdf.org/?tutorials/SSH-SDF#public_key">make a unix account accessible via public key authentication following this tutorial</a>.</h3>
|
|
|
|
<p>Not only is typing your passphrase once convenient, you can <a href="http://xkcd.com/936/">make your password very complicated and only ever type an easy to remember passphrase to access all your accounts</a>.</p>

At any time, you can type<br/><br/>
|
|
<code>
|
|
ssh-agent /bin/ksh<br/>
|
|
ssh-add $HOME/private_key.rsa<br/>
|
|
</code>
|
|
<br/>
|
|
(you can replace <code>/bin/ksh</code> by your favorite shell). Any command issued from then on that uses <code>ssh</code> to interact with a server that hosts your public key (e.g. <code>ssh, sshfs, rsync</code>) will not require a password e.g.
|
|
<br/><br/>
|
|
<code>
|
|
home_pc$ ssh-agent /bin/ksh<br/>
|
|
home_pc$ ssh-add $HOME/public_key.rsa<br/>
|
|
Enter passphrase for /home/user/public_key.rsa:<br/>
|
|
Identity added: /home/user/public_key.rsa (/home/user/public_key.rsa)<br/>
|
|
home_pc$ ssh miku.freeshell.org<br/>
|
|
miku$

</code>
|

<br/><br/>
|
|
run at login (e.g. via $HOME/.xinitrc or as a "Startup Application in Gnome/KDE"). You should get a popup asking for your passphrase.

You may have to change your openssh formatted private key to PuTTY's .ppk format via <a href="http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html">PuTTYgen</a>.
