Thanks for the note, anyway I'll need to wait a bit since this site is down last three days. >> 3) gnome-terminal slowness. Yes, I know gnome-terminal is slow.

Could you be so kind and point me into the direction of the right API to get the temperatures from drives and CPU/chipset? Also if possible API to get all appropriate SMART disk attributes? So far I've been just quickly going thorough various marketing related docs about "self-healing", but when I get to the real sensors details, it more looks like draft of future implementation: http://www.opensolaris.org/os/project/sensors/ But I'm just Solaris newbie so perhaps I don't look into the right space... Thanks! Karel
