Version 7.5.x im Pool
Verifiziert am 12.10.2018: Im Pool und auf den Shell-Servern steht sage ebenfalls zur Verfügung. Jeder Nutzer kann einfach einen lokalen Server starten:
user@shell:~$ sage ┌────────────────────────────────────────────────────────────────────┐ │ SageMath version 7.5.1, Release Date: 2017-01-15 │ │ Type "notebook()" for the browser-based notebook interface. │ │ Type "help()" for help. │ └────────────────────────────────────────────────────────────────────┘ sage: notebook( port=12002 ) The notebook files are stored in: sage_notebook.sagenb Please choose a new password for the Sage Notebook 'admin' user. Do _not_ choose a stupid password, since anybody who could guess your password and connect to your machine could access or delete your files. NOTE: Only the hash of the password you type is stored by Sage. You can change your password by typing notebook(reset=True). Enter new password: Retype new password: Please login to the notebook with the username 'admin' and the above password. User admin created with the password you specified. ********************************************************************** ┌──────────────────────────────────────────────────┐ │ │ │ Open your web browser to http://localhost:12002 │ │ │ └──────────────────────────────────────────────────┘
At this point your default browser will open this url. Terminate the notebook session with Ctrl-C and exit sage with quit.
The port=12002 parameter is only relevant on shared sytems to keep concurrent notebooks apart, choose an arbitrary five-digit portnumber. Otherwise the default (port=8080) is fine.
