Important Notice

SSH Server

There are three servers that you can log in with SSH from off-campus and use OS X environment. The host names are as follows.

Preparation

Only public key authentication can be used to log in. Create a pair of public key and private key in advance on the computer that you wish to connect. The compatible public keys are RSA1(1024bit or higher), RSA2(20148bit or higher), DSA and ECDSA.

Next, Save the public key as a file with the appropriate name ($HOME/.ssh/authorized_keys) in the ECCS home directory. You can also upload the public key from Upload your SSH key for SSH server in the Secure Web Server

Connection

Connect to the SSH host server mentioned above using an appropriate SSH client. For example, if you are going to connect to ssh0-01.ecc.u-tokyo.ac.jo using SSH with a Linux or Mac OS X terminal software, enter the following.

 ssh ECCS username@ssh0-01.ecc.u-tokyo.ac.jp

Please refer to the manual on the SSH client for how to specify usernames and host names.

When you connect to the server for the first time, the fingerprint of the public key on the server will be displayed. Please make sure that this fingerprint matches with one of fingerprints in the link destination.

Please select a server with the least users as many users will tend to use it at the same time.

How to Check Your Home Directory in the Windows Environment

Only the home directory in the Mac environment will be available at login. Type in the following commands when you check the home directory (files) in the Windows environment.

 Windows_mount .sh

The home directory in the Windows environment will be mounted under "~/mnt" with read/write permissions. This function allows the users to exchange files between the Mac environment and the Windows environment without using the WebDAV server.
