- 29 Apr. 2021 - ALICE User Survey 2021 closed: The ALICE User Survey 2021 is closed. We have received responses from 76 users. We are thrilled to have this many contributions. Thank you very much for participating in the survey. We will go through all the answers now and share results from the survey here on the wiki with you.
- 29 Mar. 2021 - ALICE User Survey 2021 out: The ALICE User Survey 2021 is online. All users should have received a link and password. If you are a user and you have not received a link, please contact the ALICE Helpdesk. We hope that you take the time to fill it out and help us improve ALICE: We are looking forward to your responses.
- 29 Mar. 2021 - MATLAB 2020b available: We have updated MATLAB to version 2020b and changed the license server configuration so that ALICE can now make use of the MATLAB campus license. If you still need version 2019b, please contact the ALICE Helpdesk.
- 12 Feb. 2021 (Update 22 Feb. 2021) - SSH Connection Stability: If you recently started experiencing that your ssh connection is breaking up after a few minutes of being idle, please check the settings below for you ssh configuration for ALICE. If this does not solve the issue, please contact the ALICE Helpdesk.
- for Linux, MacOS, Windows using OpenSSH command line connection: Make sure you use "ServerAliveInterval 60" and "ServerAliveCountMax 3" to your ssh config settings.
- MobaXterm: Go to Settings -> SSH -> SSH settings and enable "SSH keepalive"
- PuTTY: Go to Settings -> Connection -> Set a non-0 value in "Settings between keepalives" (e.g., 60)
