 ## Prerequisites{#before}
 
 Generate a public/private key pair by following [Generating Key Pair and Registering Public Key](/login/pubkey), and register the public key via [the User Portal](https://web.kudpc.kyoto-u.ac.jp/portal/). 
 
 ## How to Log In{#procedure}
 1. Start 'Command Prompt' for Windows or 'Terminal' for Mac.<br>
 On Windows, you can also log in using [MobaXterm](/login/mobaxterm). MobaXterm is a handy toolbox for x11 servers, SSH clients, file transfers, etc.
 2. Connect to the login node using the ssh command.
 ```nohighlight
 $ ssh username@hostname
 ```
 3.  If a prompt of the form [username@hostname ~] is displayed, the login is successful.
 

 ### Connection Destination{#access}

 
 The host names for each system are as follows.
 
 | System Name | Host Name   | Note |

 | System B/Cloud | laurel.kudpc.kyoto-u.ac.jp | Consists of three login nodes. |
 | System C | cinnamon.kudpc.kyoto-u.ac.jp | Consists of three login nodes. |
 | System G | gardenia.kudpc.kyoto-u.ac.jp | Consists of two login nodes. |
