I had the same "trouble" on my Dell Dimension XPS (a midi tower) and
also now on my Dell Inspiron 3400 (a laptop).
Maybe it's a Dell thing?
On my laptop I have a minimal Debian install and I run very few daemons.

Hi Bill,
Nice to read your such a detailed reply.
I am planning to host some websites (some .orgs)
This server will connect to my home network (which includes neighbours
also...
almost 6-7 PCs) on one side and Internet using DSL on other side.
I need to provide user accounts on my server.
I know that the price I have been quoted is pretty low. I read the
manual
and came to know that that motherboard is providing all the this which
Intel CC820 has.
Well.... I will try to search some more on this front...and .......
Thanks,

I'd like some advice, as we are experiencing problems with our Dell
Poweredge 6300. It's the main fileserver, so when it dies, people
start making loud noises ...
Every two days or so, I come in early and find that odin (our server)
is not responding. Electrically, it appears to be running, but the
keyboard does not respond, the screen is blank (although switched
on) ... in short, nothing happens. I can't telnet into the machine,
and it doesn't respond to a ping.
In short, I have only one option: switch the damn thing on and off. Of
course, because of this, it takes about half an hour to run fsck before
becoming available.
Here is the output of /var/log/syslog, up to the point where the system
dies, and the first few lines when I reboot:
Mar 14 00:26:32 odin dhcpd: BOOTREQUEST from 00:dd:01:20:2d:5f via 10.0.4.253

Mar 14 09:46:48 odin kernel: Cannot find map file.
The thing I find strange is that this *always* happens at the same time:
just after midnight.
If anyone could tell me whether this is hardware-related (in which case
we can kick Dell's arse), or software (in which case, I have to delve
into the OS ... zoinks !!)
All responses welcome ... thanks in advance. :-)

Are the ^@'s really in the file? This COULD indicate a hacker who is
deleting his own traces, and at a very stupid way if I may say so?
The rest is just bogus from the startup. no need to worry about this,
just make sure (when you have time) you take a look at the Map file.

These marks are just because the syslogd wants to know it is still
alive, that is also usefull for you, because then you know when the
machine died (if it died)
I think you should take a look at the firewall config. Someone is either
trying to get out of the network, or is unprofessional hacking. You
should install a spoof protection (take a look at the IPCHAINS-HOWTO for
this. then you can also try to stay up late one nigt lol, just keep a
network connection open, and see what is happening, or (bets way to make
it impossible for hackers do do any harm in the evening hours) shut down
the network card for the outgoing connection. Then you can see if there
is a hacker from the external network who is trying to spoof you...
