From 21:55 to 23:08 on August 27, 2020, there was a failure
in the mail server of the Zengaku Computer System, and it
may have been impossible to send or receive e-mails during
this time.
That was resolved, now.
We apologize for any inconvenience this may cause
to our users.
Operation of some satellite rooms was changed on August 26 .
Details are below. It will be updated as needed.
Availability of Satellite Rooms
The use of zengaku PC terminals in the Academic Computing and Communications Center’s Satelite room will resume on Wednesday, August 26.
Currently available details are as follows.
・Opening time : 09:00 – 15:00
・Consider the following
– Ventilation
– Disinfecting the keyboard and mouse
– Maintaining social distance between users
– Full-time supervisor is always available.
This operation will continue at the Academic Computing and Communications Center’s Satelite room from October onwards.
We will secure access on the terminals for “Data Science” (Required course for first-year students starting in the fall semester) students (for not have a computer at home) .
Due to the online class period, the number of users using the remote desktop service is increasing.
This service is not designed to be used for online classes.
If about 30 users connect to the service at the same time, the following may occur
・The server load will increase.
・Sign-in failure.
(The above picture is an error screen.)
To avoid errors, please consider the following.
Verify that the required software is available outside of the Remote Desktop Service.
Some of the licensed software contracted by the University of Tsukuba can be installed on students’ personal computers.
In this case, please switch to working on your own PC instead of connecting to Remote Desktop Service.
The software that can be used on the personal computer is as follows
Microsoft Office
Trend Micro anti-virus software
SPSS
Mathematica
ArcGIS
The satellite rooms will be locked down for a while to prevent the coronavirus.
From Apr. 24, 2020 (Fri), we will block outgoing TCP port 25 from the Windows
remote desktop of the Zengaku Computer System to improve security. Currently,
most of this communication is for unauthorized access, and this block has
almost no effect on the operating system or applications.
Starting October 1, 2018, we will be introducing a process for forced-terminating continuously running programs from the Linux (Ubuntu) server of the Zengaku Computer System. It is programs running for more than two weeks (i.e. consuming more than two weeks CPU time) that this process forced-terminates.
