Hi:

I'm just speculating here (I'm not an expert on Irix internals), but the
following default permissions in Irix 5.3 look a bit dangerous to me:

crw-rw-rw-    1 root     sys       10, 56 Sep 11  1995 /dev/gfx
crw-rw-rw-    2 root     sys        0, 30 Sep 11  1995 /dev/keybd
crw-rw-rw-    2 root     sys        0, 31 Sep 11  1995 /dev/mouse

Does this mean that anybody can read/write to the graphics display, the
keyboard and the mouse?

Best regards.
