SI makes available to Técnico community a Unix shell service.
This shell runs on the Sigma server, at sigma.tecnico.ulisboa.pt, accessible through applications with SSH protocol.
Users authenticate to Sigma with the Técnico ID and can run on it:
- projects;
- scientific calculation work;
- programs of research, experimentation and/or simulation;
- native Unix applications.
Sigma (16 GB RAM) bases its storage on the AFS service.
Who has access to the sigma server?
All users with Técnico ID can have access to the sigma server through the domain sigma.tecnico.ulisboa.pt, using as login credentials the respective username and password associated to the Técnico ID, since there is no need for an explicit user registration process.
In order to have access to the sigma server it is necessary to activate the “shell Unix” service in the DSI self-service page.
