+== ssh configuration ==
+
+You can add the following lines to `~/.ssh/config` on your local machine:
+{{{
+#!sh
+Host gp greenplanet gplogin1.ps.uci.edu gplogin2.ps.uci.edu
+  HostName gplogin1.ps.uci.edu
+  User YOURGREENPLANETUSERNAME
+  HostKeyAlias gplogin1.ps.uci.edu
+  HostbasedAuthentication no
+}}}
+and replace `YOURGREENPLANETUSERNAME` by your greenplanet username.
+
+Once this is done, you can ssh green planet by simply doing:
+
+{{{
+#!sh
+ssh gp
+}}}
+
 == Password-less ssh ==
 
+Once you have the account, you can setup a public key authentification in order to avoid having to input your password for each run. 
+You need to have a SSH public/private key pair. If you already have one, you can skip their creation described below. If you do not, you can create a SSH public/private key pair by typing the following command and following the prompts (no passphrase necessary):
+{{{
+#!sh
+$your_localhost% ssh-keygen -t rsa
+Generating public/private rsa key pair.
+Enter file in which to save the key (/Users/username/.ssh/id_rsa):RETURN
+Enter passphrase (empty for no passphrase):RETURN
+Enter same passphrase again:RETURN
+Your identification has been saved in /Users/username/.ssh/id_rsa.
+Your public key has been saved in /Users/username/.ssh/id_rsa.pub.
+}}}
 
+Two files were created: your private key `/Users/username/.ssh/id_rsa`, and the public key `/Users/username/.ssh/id_rsa.pub`. The private key is read-only and only for you, it is used to decrypt all correspondence encrypted with the public key. The contents of the public key need to be copied to `~/.ssh/authorized_keys` on your greenplanet account:
+
+{{{
+#!sh
+$your_localhost%scp ~/.ssh/id_rsa.pub username@your_remotehost:~
+}}}
+
+Now on '''Greenplanet''', copy the content of id_rsa.pub:
+
+{{{
+#!sh
+$your_remotehost%cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
+$your_remotehost%rm ~/id_rsa.pub
+}}}
