Thanks moon-buddy. I thought there was a way to turn off authentication so you wouldn't get prompted or need to supply login credentials.
My bigger problem is that after a start dsmadmc it times out after about 10-15 minutes with no warning. When I try to enter a command after this time period I get a funky TCP error (see example below). Below I entered a 'q proc' command and get a good response. After waiting about 15 mins I entered the command again and get the error. I must re-enter dsmadmc and log in all over again.
