I KNOW THIS IS LONG, BUT PLEAE HELP I'll describe this best I can... Running RH 7.3 as OS. It is running squid to proxy requests from private network out to the net. It works great however, here is the weird part. If the box running squid "sits still" (don't move mouse/touch keys) for about 2 minutes, the monitor shuts off. Ok thought it was a Power management thing, but don't have anything enabled, no it's not a screen saver. When this happens, net access through squid goes out for everyone. If I touch the mouse to turn back on the monitor, nothing happens. But if I touch the keyboard, the monitor turns back on, and everyone can get to the net through squid again! When monitor is out, can still telnet/ssh into the box. Freakin weird!!! It's been bugging me to the point where I don't sleep PLEASE HELP!!!!!
Okay, sounds like evil power management, /etc/rc.d/init.d/apmd stop and see if it makes it through the next few minutes, if so, use the GUI configurator to stop running apmd at all...
Dammit! Nope! Thanks though. Any one else wanna take a crack
shut down apmd, still after 2 minutes, black screen. What's really weird is that I have the same exact setup on another machine. Literally exact same hardware and modules, and it doesn't do this
Check through /var/log/messages and /var/log/syslog (if you have a syslog), to see if something is calling a suspend of some sort, and if so, what is it? Disable power management in the BIOS of the machine, this problem may not be coming from software, it might be hardware (I know, this is where the "it didn't act like that in windows" argument comes in, but windows may have overridden disk and monitor suspend and Linux hasn't.)
Those are the best forensic start points. If Linux did it, it got logged, If the machine did it, BIOS should be able to turn it off.
