+# How to  - SSH for GRICAD
+How to configure your SSH environment for friendly access to GRICAD in 6 steps.
+
+## Step 1 - Generate yours ssh keys
+If you don't already have SSH keys, create one with a nice password :
+
+```
+# ssh-keygen
+```
+
+## Step 2 - ssh-agent configuration
+To avoid having to enter your ssh password all the time, we will use the ssh-agent service.  
+Try :
+```
+# ssh-add
+```
+If an error occurs, add this lines in your .bash_profile and restart your session :
+```
+pgrep ssh-agent >/dev/null || ssh-agent -s > ~/.ssh_agent
+. ~/.ssh_agent
+ssh-add -l >/dev/null || ssh-add
+```
+
+## Step 3 - Allow your access to the bastions
+The password requested is your PERSEUS password.
+\<login\> is your PERSEUS  login
+```
+# ssh-copy-id <login>@rotule.imag.fr
+```
+and
+```
+# ssh-copy-id <login>@trinity.ujf-grenoble.fr
+```
+To verify, these two commands must now work :
+```
+# ssh <login>@rotule.imag.fr hostname
+# ssh <login>@trinity.ujf-grenoble.fr hostname
+```
+
+## Step 4 - Configuring access through bastions
+Modify (or create if it doesn't exist) your **.ssh/config** file, with :
+```
+ForwardAgent yes
+
+Host *.ciment
+  User <login>
+  ProxyCommand ssh -q <login>@access-rr-ciment.imag.fr "nc -w 60 `basename %h .ciment` %p"
+  LocalForward 8888 f-dahu:<your uid>
+  LocalForward 6006 f-dahu:<your uid + 10000>
+```
+Where :
+  - \<login\> is your PERSEUS login
+  - \<your uid\> is your uid on rotule or trinity
+  - \<your uid + 10000\> is your uid + 10000  (if uid=6500, that makes 16500)
+
+  To get your uid, try : `# ssh <your login>@rotule.imag.fr id -u`
+
+## Step 5 - Drink a coffee 
+You've earned it, but courage, it's almost over !
+
+## Step 6 - Allow your access to the frontal
+As before, the password requested is your PERSEUS password.
+```
+# ssh-copy-id f-dahu.ciment
+```
+**Fine !** Normalement, on peut maintenant accéder directement à la frontale - de manière sécurisée et simple, - sans ressaisir 18 fois son mot de passe :-)  
+**To check :**
+```
+# ssh f-dahu.ciment hostname
+f-dahu
+```
+If that doesn't work, drink another coffee and check your steps...
