| === LCD and Fans ===
| |
|
| |
| The 'lcd' program is available in source code form from the SG20 group area on groups.yahoo.com. I compiled it and hacked in settings for the SG20 (it was written for an SG30) and installed it, now I get proper readings on the lcd display and I can control the fans! THANKS Hans-Michael and Eric!
| |
| It uses the lm-sensors and smartmonctl packages.
| |
|
| |
| I added a Fahrenheit option to the command line, see /etc/default/lcd
| |
| Source code is in /usr/src/lcd-2.2.1/
| |
|
| |
| The '''lm-sensors''' package adds the ability to read the system sensors. The standard Ubuntu 2.6 kernel + lm-sensors will give you output like this:

| |
| SBr Temp: +24.8°C (high = +141°C, hyst = +54°C)
| |
|
| |
| The '''smartmontools''' package talks to the hard disk drives, and
| |
| can get the drive temperature if the drive has a sensor. I have two
| |
| drives, the Toshiba drive does not have any sensor but the newer Fujitsu drive does.
| |
|
| |
| I added code that will show the current ip addresses.
| |
|
| |
| I added code to allow running a firewall script (on and off) from the front panel button, Now that I have switched to using shorewall I will have to change this.
