Duckids
Talapas uses UO Identity Access Management system, Microsoft Active Directory, for authentication which requires all users to have a valid UO Duckid.
...
Do not repeatedly attempt to log in when you’re getting error messages. As with other uses of your DuckID at UO, if you generate a large number of login failures, all DuckID access (including things like e-mail) will be locked University-wide. Similarly, be aware of automated processes like cron jobs that might trigger this situation without your notice.
Blocked ports
Note that inbound access to the new cluster is only allowed for SSH and Open OnDemand. All other ports are blocked.Once you’re on the VPN, you can access any one of the cluster login nodes:
login1.talapas.uoregon.edulogin2.talapas.uoregon.edulogin3.talapas.uoregon.edulogin4.talapas.uoregon.edu
Load balancer
If you can’t use the VPN, you can also connect to the login loadbalancer at login.talapas.uoregon.edu
The new cluster has 4 login nodes. A load balancer is used to redirect SSH connections to different login nodes to spread the load. The load balancers choice of login node is “sticky” in that repeated connections from your IP address will go to the same login node - as long as there has been some activity within the last 24 hours.
