  1. Where is the login node for Koa located?

    Use an SSH client to connect to the login node, koa.its.hawaii.edu

  2. I have an account and a SSH client, but don't know what to do next.  Can you help me? 

    Please take a look at the following video on how to connect to Mana using an SSH client

  3. How do I access the Open onDemand interface for Mana?

    Users of Mana can access our Open onDemand instance by navigating their browser to either https://koa,its.hawaii.edu


  4. I haven't connected to Mana in over 120 days.  I attempted to log in today but it keeps telling me my password is wrong.  Why can't I connect to Mana?

    Mana has an automatic account locking policy that if a user has not connected within the past 120 days, the account will be locked.  If you are sure your username and password are correct, then please contact us at UH-HPC-Help@lists.hawaii.edu so that we can check to see if your account is locked and if so, unlock you so that you can connect to Mana once again.


  5. How do I reset my credentials for Mana?

    Mana utilizes your UH credentials, so if you have forgotten your UH account password, you will need to follow the instructions outlined in the following link to reset your password. http://www.hawaii.edu/askus/574 
    Please be aware that this will change your password for all services that utilize your UH credentials.

  6. When I try to log in using SSH, my connection hangs and does not provide me with a password prompt.  Why am I unable to connect to Mana?

    A common reason for this is failing to log in multiple times in a row, within a very short time frame.  Multiple failures from the same IP address look like someone trying to guess a user password, so an automatic process is triggered which will band the offending IP for a period of time (a few hours).  While users can wait for the ban to be automatically cleared, they can also have the ban lifted by contacting us at UH-HPC-Help@lists.hawaii.edu and asking us to check to see if you are banned and if so, to unban you.  In some rare cases, the inability to connect to Mana can be due to a network issue, if this is determined to be the case, we can work with you and the networking group within ITS to try and resolve the problem.
