As far as I remember: startx is a script that calls xinit. xinit
fires up the X server which reads its config file (e.g. XF86Config);
then it runs some commands read from .xinitrc, the main one being firing
up a window manager with something like "exec fvwm2". fvwm2 will read
its
config file, e.g. .fvwm2rc or perhaps .xinitrc is symlinked to
say xinitrc.fvwm2. Anyways the main point is that the commands for
firing up fvwm2 can be placed in .xinitrc.
About the "can't open display" error: Before running any X program,
including fvwm2, the DISPLAY environment variable should be set, e.g.
"export DISPLAY=:0.0" or "export DISPLAY=hostname:0.0" where hostname
is the host hame of your Linux machine.

Compiling in the "Magic Sys Rq" option to the kernel might help. Then

A good place to learn..hm.. Linuxnewbie.org has some of the How-To's in
'newbie' format.
Installation on my system was a snap: I'm using Mandrake 6.1 (not upgrading to
7.0 until I get a bigger hard disk. I did have to do some reading so I could
figure out how to configure sound into the kernal, but using xconfig was a
breeze.
It was such a snap to install, and has been so stable, that I eliminated my
dependance on Microsoft on my production machine. I have Star Office 5.1b, so I
can write reports and do spreadsheets. The only machine in the house now with
Windows ( we have four--my production, my wife's production, a kids machine
with JumpStart products requiring windows, and the router) is the kids machine.
If you are looking for ease of installation, I recommend either Caldera Open
Linux, or Linux-Mandrake (warning: Linux-Mandrake is for pentium class machines
or better). I haven't installed Corel, but I have heard it is great too..

Subject: How to control this very powerful and simple attack?
Date: Sun, 27 Feb 2000 13:15:04 GMT
Hello all.
A friend of mine sent a mail to me. It said something like "Hey, I've
been said that this line is able to make any unix system crash:
echo "\$0&\$0" > _ ; chmod +x _ ; ./_ "
I tried to make sense of what that line was supposed to do, and I realised
that it would create recursively hundreds, thousands of shells in seconds.
I tried it, and, yes, it did it.... In less than half a minute, my linux
box was trying to handle a load of 106, and the memory was going down and
down...
I know that there are ways in other unixes to control how many processes a
user can launch, or something like that, but I haven't seen anything like that
in the linux kernel, nor anywhere else. I tried using the "ulimit" bash command
but to no effect.
Is there any effective way to control this, either proactively (limiting users
somehow) or reactively (trying to kill all those thousands of processes once
launched) in linux? I tried to use the killall command, but without success.
After several tries, the only two ways I found to stop it were:
- Reboot the machine. Not too good when several user's are using its services
- Rename the offending executable file. Not easy it you don't know which file
it is.....

Thanks for the response.
Did a secure on the executable with chmod +s. Xcdroast starts as nonuser now,
but there's a new error that happens down the road. When I start to read tracks
as a nonser, I get the message:
Some error occurred!!!
open: permission denied
Ever seen this before? I thought it might have to do with the user
accessibility of the directory used to store the image files, but all users
have access to this directory.
Any suggestions?

No, since I think that doesn't give one control over what actually
gets written. I am not sure but I think the DOS debug facility includes
commands that let you do a binary write of a file to any specified
place on the disk, including the boot sector.

This may be a little beyond what you want to do, but to avoid all the hassles,
a very very easy to get what you want would be to just load your whole drive up
with Linux (that is always best anyway, hehe) then load a nifty little proggie
called vmware (can be found at http://www.vmware.com). This will allow you to
mound a specific partition/directory and format it to your liking. eg. FAT16,
FAT32, NTFS... and load a Virtual Machine within your Linux load. And multiple
ones at that. The newest beta version actually allows you to load Windows
2000! I have mine loaded this way with no glitches at all (so far).
You will need a large harddisk drive of course (which I don't have) but I use a
6.5GB drive with a 1GB virtual session for Win98SE and another for WinNT4.0 If
you want all them running at the same time , have plenty of memory too. This
is usually unnecessary but if you are a control freak like myself and like to
stress your pc to the max, go ahead!
What is the best part, is that it uses SMB to mount the file system and files
are easily accessible between all the OS's ... You cannot do that with a dual
boot. Plus, you can keep doing , what you are doing while your Win9x/NT is
booting in the background, or just suspend it when you need to get rid of it.
:-)
Last note, if you plan on Win32 type games , and want to squeese every bit of
performance from them, then this is not an alternative and you just wasted your
time reading this thread! hehe. Although they do work, I primarily use this
setup for software that has not yet been ported to the Linux side ... Yet...
eg. Quicken, Access (my work forces this on me) and various other little MS
only apps. Even making a bootable win9x floppy, that sort of thing.
FYI. my computer specs are as follows:
Asus P2B-LS Motherboard
P2-400
320MB ECC SDRAM
Seagate 6.5 GB 7200RPM HDD
3DFX Voodoo3 3000 AGP
all running on Mandrake Linux 7.0 ... this also works nicely on RedHat 6.1 and
Caldera 2.3
..other stuff is irrelevant to this subject matter...

Sounds like something is wrong with your eth0.
Do "/sbin/ifconfig" as root, you should see something like this:
eth0 Link encap:Ethernet HWaddr 00:00:6E:31:7D:D3
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2284 errors:0 dropped:0 overruns:0 frame:0
TX packets:1139 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:10 Base address:0x320
If you do not see anything then your eth0 device is not working. Check the
driver you are using. You can use linuxconfig to set-up the driver. I think
you have to reboot when you change the card driver. When booting watch the
messages when it says "Bringing up eth0" if it fails try another driver. Most
cards are in someway NE2000 compatible, check the cards manual.
Good luck,
Robert
