Why can't I ssh into an MSI machine?

For security, MSI requires most Unix logins to pass through login.msi.umn.edu and NX sessions through nx.msi.umn.edu. Please follow the remote access documentation for commands to access one of these servers before attempting connection to your desired destination. 

If you are experiencing continued difficulty in connecting to the servers, contact MSI Support (help@msi.umn.edu) and provide as much detail as possible, including: your IP address, the machine you are connecting to, the software used for the connection, the error message, and your MSI username. 

Please note that MSI schedules a monthly maintenance window every first Wednesday of the month; if you check the status page you can see if a given system is currently available.
