I usually use one of the following to check temperature of Linux-based computers:
$ cat /proc/acpi/thermal_zone/THM/temperature $ acpi -V $ sensors
However, on the current system I am using (Debian derived distro) the first one doesn't exist and the second does not show the temperature. The third one only worked after convincing the server admin to install lm_sensors. Is there another way to check in the event that for whatever reason a server admin would deny my request to install lm_sensors? From where does lm_sensors get the temp?
