On the supercomputer side, there are no particular restrictions on access to SSH (TCP protocol port 22).
However, your institution's security policy may restrict this, so contacting your network administrator may resolve the issue.
Please note that the supercomputer's login method is limited to SSH public key authentication, and password authentication is not supported.
If you have forgotten both, please get in touch with Supercomputing Services of ICT Support Center.
If you have forgotten your password and you have the "大型計算機システム利用承認書(Approval Notice)," please use the User Portal You can reset your password from.
If you are unable to reset it yourself, don't hesitate to get in touch with us.
Please get in touch with the Supercomputing Services of ICT Support Center.
