Questions

• How do I log in to the system?

Talk about logging in to remote system - connecting to a head node by logging in from your computer

Need these pieces of info to log in:

• connection type: ssh
• where you log in: hostname, port number
• authentication: username, password

Give software options + sample commands for Windows, Linux, Mac (putty or terminal)

On our system

To use CHTC’s high throughput compute system, you will log in to one of our submit servers, using one of the following two hostnames:

• submit-3.chtc.wisc.edu
• submit-5.chtc.wisc.edu

Your username and password will be your campus NetId and password, unless you are an off-campus collaborator and have been provided with a different username.

Firewalls

Note that our submit servers have a firewall to stop off-campus connections. If you are not connected to a campus network, you will need to use the campus VPN to make it appear that you are on campus so you can connect to the submit servers.

Exercise

Log in to the CHTC submit server where you have your account.

Key Points

• To log in, you will need an account name and password, and the name of the login computer.
