[Note: This problem may exist in more than one Red Hat distribution (I picked raw Hide since it's the latest) and in more than one 'ncurses'] When logging in from any IRIX system to a Red Hat linux system, $term is set by default to 'iris-ansi-net' which doesn't exist in your terminfo database (although it _does_ exist in /etc/termcap as an alias for iris-ansi.) This results in all curses based program complaining about an unrecognized terminal and "using dumb terminal settings". A quick workaround is to create a link from iris-ansi-net to iris-ansi (which already exists in the distribution). Please add this in your next fix to ncurses/ncurses3 or whatever. Thanks!

this will be fixed in the next release (6.1).
