Yes, it is a mobo problem.

I just have to connect to the old outlets and, see above no more booting.

Yes I reconfigured to have USB support for hid, kb and mouse and changed to 
the appropriate settings in XF86Config.

Kb and mouse were attached to the standard outlet of the mobo P6STMT which 
seems to be of poor quality. It gave problems before with the SIS630ET 
chipset, then the printer(whatever) mobo stopped working necessitating me to 
buy a printer card and now the kb went puff. Before that last event happened 
the machine was made the house training computer for the kids and wifes for 
which reason there is no Internet connection and no floppy drive. Therefore it 
is difficult to supply dmesg etc logs.

dmesg shows no errors whatsoever, neither the bootlog nor messages. The 
XF86config.log differs on the last line:
when trying to startx gnome-session and it crashes the last line of XF86Config 
is: (II)SIS(0):SISDisplayPowerManagementSet(0)
whereas when starting twm there is no such last line.

lsmod shows that the modules for usbhid, usbmouse and usbkb are all properly 
loaded and as I said kb and mouse work faultlessly with this USB adapter.

Re: Gnome, KDE won't Open

[Ray Olszewski]

Peter -- I don't have your first message here to refer back to, so let me 
first summarize what I believe your problem report is, in case I am 
misinterpreting, or misremembering, something of consequence.

When your system used a PS/2 keyboard and PS/2 mouse, you were able to 
startx and xdm/gdm into gnome (or KDE) with no problem.

You switched to a USB keyboard and mouse, and now the system cannot startx, 
or xdm/gdm, into either Gnome or KDE. In both cases, the system 
spontaneously reboots during the load process. You can, however, startx 
into twm, and axdm and gdm themselves work properly.

With that summary, and the details you offer below, I have a few thoughts.

1. Are you using a powered USB hub or unpowered connections? (More 
generally, what do you mean by "I bought an USB adopter"?) If the second, 
might this be a power supply problem? Possibly Gnome uses a video mode that 
demands more of some voltage than your P/S can provide when it is also 
powering USB devices. Possibly starting its power management detects or 
triggers some marginal problem. I admit this is fishing, but over the 
years, most of my experiences witrh spontaneous reboots ended up being 
traced back to power supplies that delivered too little peak power.

2. You report the last message you see before the reboot, and it involves 
DisplayPowerManagement. But a spontaneous reboot may be caused by whatever 
the system tries to do *after* that, with the reboot occurring before the 
STDERR display is updated. Do you have a way to check what a normal, 
successful startx with Gnome would report after this "last" message?

3. While I understand the difficulties in posting error messages and logs 
from a ssytem with neither a floppy drive not a LAN connection, surely you 
understand the difficulties in trying to help without them. Temporarily 
adding a floppy or a NIC to a system is about 10 minutes' work, and around 
here either device costs less that $US10. So you might consider having 
something on hand for these sorts of troubleshooting situations.

4.Have I correctly identified your mobo as the following?
         http://www.baber.com/baber/411/ecs_p6stmt.htm

If so, I note that it has onboard video. Since this mobo has already failed 
in two other respects, have you considered the possibility that some of its 
higher-res SVGA modes also have failed? (Are you using twm at 640x480 but 
Gnome at 1024x768, for example? Or even more extreme, are you using 
different X servers for the two?)

5. I'm having trouble understanding this part of your report:

 >>When I open gnome-panel or kicker from
 >> within twm causes a crash when then trying to open an application from 
those
 >> panels.

What actual application(s) do you try? What sort of "crash" occurs? (The 
system hangs? It spontaneously reboots? Something else?) What happens if 
you try to open those same apps without using the Gnome or KDE interfaces 
(for example, if you launch them from an xterm)?

6. This is a real long shot ... but your system isn't exactly overloaded 
with RAM. (What is "KRAM", BTW? Or is that K=kilo, which I suppose (hope) 
is just a typo ... surely the system has 118 MB RAM, 435 MB swap, not 118 
and 435 KB.) Might this be a memory (or swap partition) problem? What does 
"free" report about memory and swap usage just before you try to start 
Gnome or KDE? Are you able to use swap successfully in other ways?

Displaying 'ping' data with 'tcpdump' ?

[chuck gelm]

Hi, Everyone:

  I am having difficulty displaying the pattern data
inside a 'ping' packet using 'tcpdump'.

  I am sending a periodic 'broadcast' padded with 'data':
ping -f -i 3600 -p 204445204E43385120   #" DE NC8Q "

  I want to display this data on a console.  I am using
'tcpdump -i eth1 -v -X'
but this shows too much data/activity.

'tcpdump -i eth1 -v -X port 7'  displays nothing.

Perhaps something other than 'tcpdump' would be more suitable?

1. How can I display only the 'echo request' packets?
2. How can I display only the 'echo reply'   packets?

Regards, Chuck

         tcpdump icmp[icmptype]=icmp-echoreply -v -X

:-)  Thanks, Ray.

  Now I see it in the man page. :-|

I am 'playing' with some 802.11b (USA FCC Part 15) devices
and configuring them to use frequencies inside the USA Amateur
Radio assignment (USA FCC part 97).
Then I can legally use antennas other than the ones that came
with the device.  I have some 24dbi gain dish antennas and I
want to try to use passive reflectors to overcome the
limitations of 'line of sight'.

  This 'ping - tcpdump' will show that I am compling with the
'Station Identification' requirements.

Many thanks,
Chuck

Re: Gnome, KDE won't Open

[Peter]

Thanks Ray! I just solved the problem.

The bloke in the computer shop had the System Share Memory Size in the BIOS 
set to 8. When I now reset it to the original 32 everything is working again 
fine. I saw him fumbling around the BIOS, however he was so fast that I could 
not follow.

I got the idea after your hint above when I noticed that the swap memory was 
not really used after having opened in twm via xterm applications like 
abiword, gnumeric, konqueror, gkrellm simultaneously, then trying to open 
other applications I would get segmentation fault. After closing abiword, 
gnumeric, etc they could not be reopened, segmentation fault. Even rebooting 
would not completely finish and end with segmentation fault.

That should naturally read adapter.
It plugs on one end into the USB socket of the mobo and has 2 sockets on the 
other end, one for kb and one for mouse.
