[LOGic] More on remote operation

Dan, TNX for solving a mystery for me. Since I had Verizon FIOS installed
with a wireless router to the computer, I periodically need to reboot in
order to re-establish a connection. 

At least I now know that my observation was correct and that I am not alone
in the solution. What I do not understand is why?

As i have mentioned i have had many PC's (Windows OS) running for long
periods of time , long periods of time i mean > 6 months , a couple for much
longer than a year with no reboots. I must mention that the OS's were Win 2K
Pro and XP Pro , the one area that i have had trouble with is when they run
with wireless Ethernet cards , in this case you either have to reboot often
or do a repair of the connection. I assume if you are running remotely that
more than likely you are not running wireless.... although i can see where
that could happen , if that is the case there are ways to reset the wireless
Ethernet connection pragmatically. I do not believe i have ever had a
situation where I had to do a "cold" reboot to re-establish connections to
peripherals in the kind that would be used for a remote site. I will admit
that there have been times when i have "warm" rebooted just because i
thought i should , you know it seems fashionable to do it etc.... even  when
i was running a cluster under Linux i did the same thing , why , i don't
know ....

I think that with the modern Windows OS's you can do it , (meaning W2K Pro
and XP Pro) , i don't think i would get near Vista with remote stuff ,
although that is just a feeling , since i have no experience with Vista and
MS is pushing Windows 7 so hard as a replacement i feel that Vista is the
Windows ME of late.

There are also many ways to do a soft/warm reboot remotely that i wouldn't
hesitate to do that either , although on a remote machine i would limit the
amount of non-essential (to remote operation) software that was installed ,
put a good HARDWARE firewall in front of it and remote desktop (on a non
standard port) into your machine and you have total control , i do it every
day between work->work , home->work and work->home machines.

i am sure i missed some of your points/questions with my rambling , if so
ask me again and i will give you my experiences....

Dan:

Do you ever need to warm/cold boot the PC's (and peripherals), even if
momentarily, to break a lockup, reestablish network connections, etc., etc.?
Does coldboot actually remove power from the secondaries of the power
supply?

I'm not trying to give you a hard time here, I'm just trying to explore how
much "exercise" PC's running 24x7 (especially remote PC's) require. And am
not so much exporing fire risk (altho that's always worth some study) as I
am just lockups, debugging, and other voodoo associated with networking.

work I have 18 or so PC's in the lab that pretty much run 24/7 and all
through the plant there are probably 4-500 machines always on and we have
never had a fire.... the biggest problem we have is with the few pc's that
do get shut off , the hard drives do not like to sit not spinning for very
long...

It's true that I've never seen anything like it in any "run-in" computer
I've used over the past 25 years. Maybe I should reconsider...

smells, but never actually catch fire. I know such things can happen... but
most of the fires I have heard about are to do with laptops and their
batteries. Perhaps you are being overly cautious. A smoke detector coupled
to a breaker might be a solution... such things must exist.

Fortunately, I was in the house and smelled the smoke before the fire
spread. It's made me a bit nervous about leaving town with a computer
running. Of course, a fire could happen anytime the computer is running, but
it seems to me that the risk would be reduced if it were only running when I
was using it.

period of time means that when you wake them up their OS patches, virus
signatures and such are out of date. Modern computers can be configured to
go into a very low state of activity after a prolonged period of activity. I
would also strongly recommend a UPS for your computer and router.

The real question is that of the best way to turn on the computer. Does
anyone on the reflector have any recommendations based upon actual
experience with the commercially available circuit boards that will do this?
I hate to go away and leave everything running for a week or two at a time
with no one at home.
