it's called xrdp and it says unknown protocol version specified. connection refused.

Still sounds unlikely. The batch job may have something to do with it but it might just be loading the machine in such a way that it's enough to cause a flaky hardware problem to reset the machine.

I expect it's something like that, but this machine's been rock solid for years.

Maybe you're running out of memory or something? IDK, leave it to Ford to ask a question and then answer it a few minutes later by himself.... LOL

well, it used to be that when I wanted to know something unixy, I'd ask here, because that's all there way. was.
Now it's habit, but I later remember to ask the google.

Asking the Google is definitely a good thing. :)

maybe its just the cpu fan that is bad or s.th. else, and once the box gets loaded it crashes.

scp shouldn't pin the box.

Well, the other day I noticed that the ubuntu CD boots up with an option to run memtest86+ or whatever it's called.
so I ran that on the machine and in 10 seconds it came up with a memory error. Yay.
So I shuffled chips around and it went away. Not very inspiring.
But I tried the copy again and it didn't reboot the machine so maybe I'm onto something.

So for all your x86 people out there.
Just curious... Memory comes in sticks of many megs.
but the machine as far as I know still has a good old 386 like mode where it's got that 640K and 1meg thing going on.
I imagine the new OSes don't use that at all, but does the processor map the first bit of memory into that weirdness?
As in: they don't actually put 640K on the motherboard do they?

Ford,actualy you're talking about the 8086 mode; its still some lines of assembler for the bios to switch to real mode, which actualy is there since the 386 cpu.

486 introduced microcode and integrated numeric coprocessing unit.

so, since 486 its a risc in the inside programmable like a cisc from the outside.

(I hope nite*, you don't accuse me again to write in non-english ;)

dothebart has it right. When the cpu is running in real mode, it treats the first 640 KB (which Bill Gates told us would be enough for anybody) is what's accessible without resorting to any weird bank switching tricks. Modern operating systems only use real mode for the first stage boot loader (LILO, GRUB, NTLDR, whatever) and then switch to 32-bit or 64-bit protected mode immediately, at which point the whole machine becomes a flat memory space.

You know, at one point I knew all that, it came back as you said it, but it's been so long, I forgot.

You know, I'm a frikkin idiot.

A couple of weeks ago I was having problems with vmware making my machine reboot. I blamed vmware.
a few days ago I started having a problem where doing an scp caused the machine to reboot.
Only took me 3 days to connect the dots. Duh. DUUUUUUUUUUUH.

Still don't know what's wrong with the machine, but I swapped out more memory chips (any other suggestions?) and I await a reboot.

Just a  few general things:

Heat build up...clean the dust out of your heat sink(s). Make sure the thermal paste hasn't dried up.

Power supplies go bad quite often.  Check that the voltage levels are staying in spec. 

Make sure you have an adequately sized power supply. 

Loose cables, makes sure everything is seated properly. 

If there is a button battery on the MB, check that out too. 

I once had a USB hub that caused reboots due to a loose power connecter on the hub.

I've had problems with older peripherals on new systems.  Like an ancient 2x cd drive on  a dual core system.  ( I never throw things away).

well this morning I foudn it had rebooted again ,so I swapped some more memory chips and have been beating on it all day, so far no problems.
I'll await tomorrow morning and see if it stays up all night.
IF not I'll start trying your suggestions.

I have a lot of old stuff hooked up to this machine, but I use it all, so I don't really wanna get rid of itl.

Argh
Well. I tried to fix it and now it doesn't boot.
It gets 3 seconds past grub and reboots.
I replaced memory and power supply, reseated everything, and now it's worse.
Sounds like time for new motherboard.
The only cards in the machine are video (agp) and network card, can't really do without those...

Isn't an AGP card a little modern for you?

Well, I've been needing a new server motherboard/processor for a while now.
Something speedy enough but budget. Like no more than $200 including processor, RAM, motherboard, and cpu fan. If you come up with anything good let me know.
Every time I look I read something bad about what I am about to get and am frozen with indecision...

I think it all sucks.
There seems to be less and less of fewer and fewer things.
Certainly there's lots of motheboards, but not as many as there used to be.
Same thing with chips.
Anyway, I copped out and went with a combo package. $60 got me a sempron 3000 with motherboard.
It's got video and ethernet on it, and 2 184 pin slots for memory.
There's 240 pin 200 pin and 184 pin memory now.
No idea what the others are like, but gone are the days of lots of slots.
In soviet america you buy 1 chip with all the memory you want. You want 2 gig, you buy a 2 gig chip.
http://www.newegg.com/Product/Product.aspx?Item=N82E16813135060
It's even got a serial port on it.
But it's not fast or modern, but it's cheap and has plugs for my non SATA hard drives.

So out of sheer boredom, I've been playing with the dying machine.
I've noticed 2 more things.
I can boot into the bios and it works just fine.
It will boot to grub and then as soon as it changes video mode to show the ubuntu slash screen it reboots.
Sometimes it reboots quickly and somtimes it waits a few seconds. During that wait, the power button doesn't work, which to me means some part of the motherboard shutdown, but wait long enough and it will reboot.
So it's starting to sound like either the video card (which I don't have a spare to replace with) or heat. I took the heatsink off and put more goop on, and blew air over the fan (oh my the grey dustcloud that came out of doing that) but no change.
Any more thoughts?
