The public key is like a lock, anybody can see it but only the person with the private key can unlock it. SSH secures information with the use of a private and public key. ("X11-forwarding" item must be checked in the message displayed upon successful login.The Secure SHell (SSH) protocol is used to securely access remote servers. Therefore, you can use X window application without special settings. In the left pane of the window (marked with red square), you can download/upload files via SFTP. You may see window like above if you successfully logged in. 0K元8Yn/kBee1pAuxyKwenEwXjtPxr9ZElolfVqXvbI (SHA256).wnEM30z4AxyDJ9XI/DdGr2PlNeoivFRR8v5krXHEmdU (SHA256).Valid fingerprints of the login server are listed below. This verification can be enabled by checking "Validate host identity at first connection" item in SSH tab of "Settings" -> "Configuration" menu. Note: MobaXterm skips verification of the connecting host in default. click OK to proceed.Īfter the connection, you need to input passphrase of private key. check "Use private key" and specify private key file location (both of OpenSSH style and PuTTY style private keys are accepted). click "Advanced SSH settings" tab to expand this. check "Specify username", then input RCCS user ID (three-letters ID) in the textbox. input login server name .jp into the box. You need to complete following settings in this page.ġ. Theh, Click "SSH" to create a new SSH session. Click "Session" button on top-left part of the window to create a new session. Quit MobaKeyGen (or restart MobaXterm) to go back to the MobaXterm window. Please note that the public key here is an OpenSSH type one, not the one from "Save public key" button. Please register your public key according to the instructions in. You need to register the public key before login. (NOTE: THE PRIVATE KEY FILE MUST BE KEPT SECRET!)

We, RCCS, recommend passphrase of 10 or more characters containing 4 types of characters - "lower-case", "upper-case", "number", and "symbol".Īfter setting passphrase, click "Save private key" button to save the key. You can set passphrase for private key here. (If you lost the private key, you need to generate a new key.) You can rebuild public keys via "Load" button or "Conversion" menu if you still have private key. Extract all the contents in this filed into notepad or others, and then save it! (Do not miss ssh-/ecdsa- part in the beginning!) Note: you don't need public key from "Save public key" button we need only OpenSSH format one. The public key shown as a string in this field is what we need. Once the key generation completed, the appearance of the window will change like above. Key Generation (2) - set passphrase and save keys You need to move mouse cursor around to proceed the key generation after clicking the button. Once you click the "Generate" button, the key generation will begin. This is not available on RCCS login server. In case of EdDSA, ECDSA or RSA type, you may find optional item at the position specified by "2". *Old MobaXterm Personal versions do not support SHA2 algorithms of RSA (rsa-sha2-256/512). This type is not yet available on RCCS login server. Please choose EdDSA (Ed25519) if you have no preference. You may see window like above when you invoke MobaKeyGen (SSH Key Generator).ĮdDSA (Ed25519), ECDSA (256, 384, 521 bits), and RSA 4096 bits * of keys are recommended in RCCS. If you already have PuTTY session settings (in registry?), they will be automatically loaded on left pane of the window. Launch MobaXterm and select MobaKeyGen (SSH key generator) from "Tools" menu. SSH Key Generation using MobaKeyGen Invoke Key Generator of MobaXterm The aim of this page is to explain how to login to RCSS supercomputer using MobaXterm.
