 The first task you **absolutely** need to do when you receive your password is to change it. This is due to you receiving your password via email. If the password is not changed in 1 day, your user access will be revoked, and the process needs to be restarted.
+[[https://forms.gle/dB6uCc4gBngEeUdY6|Here is a form that you can use to apply for access to the cluster.]]
+**It is very important that you change the password as soon as you get access to the cluster.**
+The password can be changed by logging into a machine you have access to using SSH.
+The command to update your password is `passwd`. You will first be prompted for your current password, and then the new password.
 ===== Access the cluster =====
-The machines provided as part of the cluster are on a private network, meaning that in order to access them, you need to be logged on to the [[https://en.wikipedia.org/wiki/Virtual_private_network|VPN]].
+The machines provided as part of the cluster are on a network that is not accessible from the wider internet, meaning that in order to access them, you need to be logged on to the [[https://en.wikipedia.org/wiki/Virtual_private_network|VPN]].
-The VPN is hosted at ''vpn.ru.is'', and to log onto it you need to use your sleep.ru.is login credentials.
-The VPN is differently accessible depending on the OS you are running.
+Please use a VPN client such as Cisco AnyConnect to log into the RU VPN __vpn.ru.is__. Then use the following log-in credentials:
-The correct way to use your username to log into the VPN, assuming a user called ''aardvark'', is to use ''aardvark@sleep.ru.is'' as the username, and the password normally.
-==== Windows ====
+**Username: username@sleep.ru.is**
-The Sleep Revolution VPN can be accessed with any vpn client that is compatible with cisco's anyconnect.
-An example of this is [[https://openconnect.github.io/openconnect-gui/|Openconnect]]. Alternatively, there is the cisco anyconnect client, which is however proprietary.
+Password: your newly set password
-==== Ubuntu ====
-Similarly to windows, [[https://openconnect.github.io/openconnect-gui/|Openconnect]] can be used to connect to the VPN, both with a command-line-tool and a graphical user interface.
+More detail on the VPN can be found [[cluster:usage_tips:vpn|here]].
-==== MACos ====
 ===== JupyterHub =====
+Jupyterhub is a platform that allows multiple users to access computational resources using a graphical user interface. To access the JupyterHub, follow the steps in the [[cluster:usage_tips:jupyter|Jupyter]] article.
+In order to access the JupyterHub, first open a terminal window on your computer and type:
+<code>
+ssh yourusersame@dunwich.sleep.ru.is
+</code>
+Then open a browser and access the page [[https://dunwich.sleep.ru.is/jupyter/
+]]
-Jupyterhub is a platform that allows multiple users to access computational resources using a graphical user interface. To access the Jupyterhub on salamander for example, you have to tunnel port 8000 on salamander to port 8000 on your local machine. This is possible on linux by running the command ''ssh YOU@salamander.sleep.ru.is -L 8000:130.208.209.2:8000''. On windows, the program [[https://mobaxterm.mobatek.net/|MobaXterm]] can be used to create this tunnel.

 ===== Security incidents =====
 In case of any security incident, it is very important that you escalate the issue directly with both the [[cluster:cluster_management_team|CMT]] and your organization's contact with the [[cluster:cluster_management_team|CMT]].
