1. Remarks

• About software
  Depending on the license, available software may be different from satellite terminals.See Software Information for datails.
• Old client may not work
  From Mac OS please use connection on Web browser or something.
• Automatical log-out after 2 hours
  In order to avoid occupation by a small number of users, for Windows desktop and Linux desktop, it automatically signs out / logs out after 2 hours from the time connection started. As it compulsorily signs out / logs out even during operation, please keep it in mind.
• Regular restart of remote desktop servers
  In order to operate the system stably, the servers for using the Windows desktop are regularly restarted. Restarts occur every day at 6:00 and 6:30, with staggered timing for each server. If the user is signed in at this point, it will not be restarted. Also, because the restart timing is different for each server, the user is not affected by the restart even when the user newly logs in.
• Regarding being judged as being in another country even though you are in Japan
  The database that manages the relationship between IP addresses and countries used by the firewall installed at the University of Tsukuba is used to determine whether your connection is to Japan or not.
  When the organization to which the IP address is assigned changes, this database is also updated, but it may not be reflected immediately. As a result, judgments may be incorrect.
  The University of Tsukuba is unable to correct this database. We appreciate your understanding and cooperation.

3. Using Linux Desktop on the Zengaku Computer System

This section describes the instructions for using Linux desktop from Windows. To use Linux desktop from mac OS or Linux, use similar software intended for each OS.

3-1. VNC Vewer

VNC connections to the Linux server can only be made from IPs that are determined to be from Japan.

[Connecting]

1. Download a VNC Viewer suitable for your environment from http://www.realvnc.com/download/viewer/

   When you disconnect, the last screen will be displayed as thumbnail on the VNC Viewer, but be aware that the session is not stored.
   

4. Using UNIX shell on the Zengaku Computer System (SSH Access)

SSH connections to the Linux server require public key authentication from outside our university.

[Connecting]

Using an SSH client, connect to either of

icho01.u.tsukuba.ac.jp:22
icho02.u.tsukuba.ac.jp:22
kiri.u.tsukuba.ac.jp:22

If you are from off-campus, you need to use VPN Service or log in with public-key authentication.

When logging in for the first time, possibly a confirmation message as to whether to trust the server is displayed since the host key of the server is not cached. In that case, check the fingerprint of the key displayed in the message and the fingerprint below to make sure if you are connected to the correct server.

Fingerprint:
Only icho01 is available at this time.
