1. disconnect all cables
2. remove CD Rom, hard drive and floppy
3. disconnect and remove monitor and smash with sledgehammer
4. remove all memory chips and PCI cards
5. remove all keys from keyboard and replace with chicklets
6. cover entire computer with 3 layers of aluminum foil
7. dig a 15 to 20 meter whole and place computer in it.
8 fill hole with concrete and metal chaff
9 after cement is dry build a McDonalds or Starbucks on top of it
Windows is now secure!

Is there an Linux equivalent to the "format" command in DOS?
I want to clear a partition of all its data. I have looked and looked
and have not seen anything in Linux that does this for you. Is it
possible that "mkfs" does this? This command is supposed to make an
ext2 filesystem. What does it do to an already existing ext2 file
system? Does it clear all the data and then "remake" the file system?
If not how does one "format" a Linux partition? Thanks.

You use a fs specific program like mke2fs (mkfs is just a wrapper
application).
It does not really clear the partition of data, though. If you want
to clear out a partition for some reason, then you can do this ...
dd if=/dev/zero of=/dev/sda1 bs=512
... for instance and with SCSI drives (sd*).
In any case make sure whatever you pass to dd is right -- make sure
thrice as if not, then you can in deep s*** pretty quick 8-)
You can use mkswap, too but then you'd have to change the partition
type first.

Interesting disussion. Let me describe my situation and ask for advice. My
Linux machine is LAN'ed to 3+ others, at least one of which can be running
Windows and unused at any time. It seems to me that by far the simplest
solution would be to grab the Windows screen over the LAN, put it up as an X
window, and send mouse clicks and keystrokes back. Presto, winapps running at
native speed in full native mode on a linux box. If all this runs on top of
Samba, I could have transparent access to files and printers as well.
This is beyond my programming abilities, but it is not obvious to me that it
is a fundamentally stupid or impractical idea,. Of course, I could simply put
one of the Windows boxes on my desk, but
a) There is too much crap on my desk already, and
b) I need to be able to cut and paste from one app/os to another.
Does anyone see that this could be implemented in 300 lines of tcl? Has
somebody already done it? Is the whole idea idiotic?

Subject: Making Getty work with the serial port COM1
Date: Fri, 30 Mar 2001 16:34:24 -0800
Hi,
I'm trying to get getty to work with the serial port COM1. I have read
through the HOWTO for serial port terminal and I understand the various
steps in there to configure your serial port using setserial, configure
getty using /etc/gettydefs. However I can't get this to work. My setup is a
simple PC (e-machine 633) running RH 6.2 with COM1 connected using a null
modem cable to a laptop running Win 2000 and hyperterminal looking at COM1.
I can say ls ~ > /dev/ttyS0 and the listing of my home directory shows up on
the hyperterminal, but I can't get getty to start on COM1. When I try to
start getty, it waits for a couple of seconds and then just terminates my
telnet session to the linux box.
I tried mgetty, but it just sits there and does not seem to do anything.
I am under the impression that I should be able to ask getty to start with
/dev/ttyS0 and if I hit enter on my hyperterminal session I should get a
login prompt. Is that how this is supposed to work? Any other references I
should check to get this working?
Thanks much!

This seems rather cumbersome in that you mean I would have to use fdisk and
change the device ID to Linux swap or 82 and then use mkswap on it? Then
change the ID back to Linux Native or 83?

Oh, come on! Saying something over and over again doesn't make it true.
ALL versions of Windows are far less secure than *ANY* version of Unix/Linux/etc.

I would recommend not compiling from the source, but rather using
binary RPM files to install it. I run Redhat 7.0, and had some
problems when I tried to install QT and then KDE from the source tar.gz
packages. Anyway, the complete instructions and rpm files are at
http://www.kde.org/announcements/announce-2.1.1.html
I've found that RPMs are generally a better solution. They are smaller
than source packages, take far less time to install, and are easy to
install/uninstall. Anyway, good luck!

Although I don't provide a lot of depth on any one

/boot/System.map is a representation of the defalut kernel symbol table
When the kernel or modules query symbol information for debugging, the files
looked for are:
/boot/System.map-<version-code>
/boot/System.map
I have several kernel versions, and System.map is good for only one version.
/boot/System.map-2.2.13
/boot/System.map-2.2.17
/boot/System.map-2.2.17-20
/boot/System.map-2.4.0
/boot/System.map-2.4.2
This keeps the various kernels and their modules happy.
Modules for the kernels are stored in the respective directories under
/lib/modules
/lib/modules/2.2.13
/lib/modules/2.2.17
/lib/modules/2.2.17-20
/lib/modules/2.2.18
/lib/modules/2.4.0
/lib/modules/2.4.2
Note: that kernel version 2.2.18 has no specified /System.map-2.2.18
represented, therefore
symbols for debugging will come from /boot/System.map. All kernels boot OK
without the
System.map files, but the presence is invaluable for debugging code.
Hope this helps!

? Not quite... ReiserFS keeps a filesystem log ("journal") and it goes
sort of like this:
0. Write to log, "I am going to write file X"
1. Write file X
2. Remove log entry written in step 0
Filesystem integrity is preserved in almost all cases. If a crash
occurs during step 0, bad log entries are removed on the next mount. If
a crash occurs during step 1, on the next mount, the driver checks the
log and writes file X if it hasn't been written yet. (Note that this
also catches what happens if a crash occurs during step 2!)
Not to mention that it keeps directory entries in a B-tree for efficient
handling of directories that contain a *lot* of files. This also makes
the operation of tools like "find" very quick.

That's another feature. ReiserFS does something called "tail packing"
on files, which AFAIK involves moving files around on disk so that the
B-tree is balanced, making for more efficient operation. Since LILO
must know the exact positions of all the sectors where the kernel image
and the loading map reside. If ReiserFS shuffles /boot/vmlinuz or
/boot/map around like that, LILO will not be able to find the kernel on
the next boot!
You can work around this by making a ReiserFS /boot partition and
*always* mounting it with the "notail" option. Recent versions of LILO
can grok this. Note that you really want to make a /boot partition if
you do this; putting "notail" on / or /usr or /home could cause
performance degradation.
