 To accommodate users logging in from other locations a new access portal, ''hpc-portal.uark.edu'', is available for any user holding an active AHPCC account.  This service, upon successful login, registers the source IP address of user's client machine and adds that IP to the list of allowed IP's allowed to pass network traffic to the AHPCC login nodes.  To use the service ssh into port 2022 of hpc-portal.uark.edu.
