Partial suspension of the upgrade of the Ubuntu (Linux) servers of the Zengaku Computer System

Ubuntu (Linux) on the Zengaku Computer System was scheduled to be upgraded from 20.04 LTS to 24.04 LTS.
Linux on terminals was upgraded to 24.04 as planned, but Linux on servers (icho01, icho02, kiri) was upgraded to 22.04 because the system became unstable when upgraded to 24.04 LTS.
We are currently investigating the cause of the system instability and the possibility of future upgrades.

Attention on use of Dropbox etc. on the Zengaku Computer System

Users can install and use online storage client software such as Dropbox. It is useful, but there are some points that you should be careful. Please use it at your own risk.

  1. Be careful for the capacity difference between the online storage and your home area of the Zengaku Computer System. When data on online storage are synchronized with your home area of the Zengaku Computer System, the usage may reach the upper limit without noticing it, and causes trouble such as losing your files.
  2. For the reason described above, we recommend that you do not use it synchronously on the Zengaku Computer System but only upload and download through a browser. If you want to synchronize, please set the online storage client software carefully so that there is no problem. Especially make sure of folders to be synchronized.
  3. ACCC will not deal with troubles related to online storage client software installed individually. Please use it at your own risk.

On Measure against Account Abuse

Recently, yet more news articles report damage caused by phishing or account hijack. In fact, also here in our university, we receive reports about such damage caused by account abuse. We’d like our users to be very careful about managing accounts.

As an emergency action against incidents such as supposedly abnormal transmission of mail messages, we may temporally lock user’s account without notifying the owner of the account. Under such circumstances, we will interview the user for more information.
