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.
