After creating your account, you can log in to TSUBAME as described in this page.
Using TSUBAME2 requires you to log in to the machine with Secure Shell (SSH), which is a method to connect to remote serves securely. Here's the necessary information to do so:
|User name||Your TSUBAME account name|
|Password||Your TSUBAME account password|
|Authentication method||Password or public key. Only public key is allowed when accessing from outside the campus network.|
Note that on TSUBAME1, password login was allowed even from outside the university network, but it is now disabled. Use the public key login instead as described below.
1. Installing SSH Clients
Windows user need to install SSH client software unless already done. Popular free clients include:
Any other software compatible with OpenSSH can be used. Cygwinのインストール方法はこちら。
Standard Mac and Linux machines have OpenSSH installed by default. You can check your machine by firing up a command shell and typing "ssh". You would get a response like below with minor differences if installed:
If not installed, see the operation manual for your machine to find how to install OpenSSH.
Next, make sure the network from your local machine to TSUBAME is reachable as follows. Command "e;ping"e; is what you should for this purpose and available on most computers.
If you see messages like "host is not found", "request is timed out", or no message at all, your machine to TSUBAME is not likely to be network reachable. If that's the case, then:
Connect to the login node using the SSH client. On Mac/Linux, use the OpenSSH command from a terminal window as follows:
Windows clients can be used similarly with the information listed above, including your account name, remote host name, and your password.
Note that this method is only available for the case connecting from the university network; see below othersie.
This is necessary only when accessing from outside the university network, although it works and is more secure even when you use TSUBAME solely at the Tokyo Tech campuses.
Fore security reasons, accessing TSUBAME2 from outside the campus network requires the SSH authentication method based on public key cryptography, for which you need to create a pair of keys and to upload one of the pair to TSUBAME. Here's how:
Your public key is now uploaded and configured on TSUBAME. Putty and TerTerm users would need to configure your clients to use the private key to do authentication when accessing the login machine. Mac and Linux users should not need extra configurations.
At this stage, if everything is correctly configured, you should be able to log in to TSUBAME with the key pair even from outside the campus network. You must type your key password if necessary. If logging in fails, something is not set correctly; see below for troubleshooting.
When you have a problem to access TSUBAME, please check your network connectivity as described above.
