Enabling Encryption for Interactive Jobs

Enabling Encryption for Interactive Jobs

Dear Users,

During this week, we will enable encryption for interactive jobs. This step is essential to enhance the security of data transmission and communication within the MetaCentrum computing environment.

For you as users, this update brings two practical changes that we would like to bring to your attention:

1. Kerberos Ticket Verification upon Login

The system will now strictly require a valid Kerberos ticket.

• If you do not have a valid Kerberos ticket at the moment the interactive job starts, the system will prompt you to renew it (enter password / kinit) when you attempt to connect to the job.

• If your ticket is valid, the login process will proceed as usual without further interaction.

2. Connection Time Limit (Timeout)

We are introducing a security time limit for starting your work.

• Once the interactive job starts on the cluster (a compute node is allocated), you have 3 hours to start interacting with the job.

• If you do not connect to the running job within 3 hours, it will be automatically cancelled.

These measures help us maintain a secure and efficiently utilized infrastructure. Thank you for your understanding.

In case of any issues, please contact user support.

The MetaCentrum Team
