Thanks for all the input. I was gifted a NeXT machine which is really nice
but the screen is going dim ( a common problem with them apparently )and is
only B & W. It works so well on a motorola 68040 & 16mb ram that I thought
Linux on a 486 might work as well and give me a color screen and better
printer support. But then when I researched everything points to pretty
heavy hardware. Oh well.
It sounds like Afterstep might be my best option but I'll need more ram and
maybe a bigger HD. I have a Digital 486/50 with 16mb and either 200mb or
500mb hd, I'll have to fire it up and check.

For non-interactive use, cron as an example, you expect people to use
PATH=/usr/local/bin /whatever/path/perl-program-with-#!/usr/bin/env-perl?

Oh, I'm polite and willing alright, enough to keep a machine running with MS

initrd is "initial ramdisk" and contains the applicable modules for
booting from a scsi device in your case. If you haven't already, you need
to make a new initrd for the new kernel on the scsi machine.
Read "man initrd" for more info.
You didn't mention what distro, but you may want to check if mkinitrd is
on your system. It makes creating a new initrd simple. Somehting like:
mkinitrd /boot/initrd-2.4.1.img 2.4.1
Then edit lilo.conf to point to the initrd: "initrd=/boot/initrd-2.4.1.img"
in the appropriate "image" section should do the trick.
"man mkinitrd" for more info if its installed.

I use Redhat 6.2. For some reason I don't have in.ftpd:
# pwd
/usr/sbin
# ls in.*d
in.fingerd in.ntalkd in.rlogind in.talkd in.tftpd
in.identd in.rexecd in.rshd in.telnetd
What caused this during installation? I don't recall selecting it to be NOT installed.
Which CD contains in.ftpd? I wonder if I'm missing other important utilities.
Thanks for help.

Try to manually configure it with "ifconfig". If this fails then
the hardware isn't being seen. Use "kudzu" program to detect hardware,
but this is supposed to be run at every boot. Still I don't think it
can hurt to run it manually.
If the ifconfig solved your problem, then reboot and try this:
After you system comes up, as root type:
/etc/rc.d/init.d/network restart
In RH6.2 (which I have, and ran into a similar problem), the brain-dead
network script *deliberately* ignores all but the primary network
connection if invoked with "start". It will do a full network setup
only when invoked with "restart".
If this solves your problem, you need to hack the network script.
Hope this helps!

Dear all
Server of my friend(RedHat 6.2) was attacked by some kind of
rootkits(attack by wu-ftp BOF). It change many things. One of changing is
copy new script to command netstat and ps . My friend try to delete that
script but he can't. Because that scripts have copy inode from other file .
How do hacker do? And How to delete that script file ?
Thanks

Look in the mtrr code, if you need to know more about it.
You can give a proc entry any (apparent) size you like.

Try "chattr -i /path/to/filename" then delete it.
But once the system has been "Cracked" it is highly recommended to do a
format and reinstall. That is the only way to be sure that you don't
miss a back door somewhere. Then secure the system before putting it on
line again.

In theory there should be none. But both 'bigger' browsers (Netscape,
Internet Explorer) have crappy implementations, so the secure sand box is
weakened against perfomance and functionallity. But Java is safer then
JavaScript.

But it must be run from the new HDD.
using the new kernel_image (even though it is just a copy)
LILO uses the physical address of those files, so if you copy a
file it is no longer at the same (physical) location.

No automagical way.
The table exists, and was made with different CHS settings then the
one you're using now. You cannot safely change it, unless you know
*exactly* what you're doing.

Hehe, but M$-Word is ok, I've written my whole PhD-Thesis in Word. No
offense to you, but Word is not that bad. Especially if you have EndNote,
so the endnotes for references really work nifty.

If you use LyX (graphical WYSIWIG frontend for LaTeX), the learning
curve isn't that steep. My recommendation: Try LyX, and then switch to
LaTex (if you want).

Hi,
I would suspect you chose a 'workstation' installation as this leaves
out the ftp server.
On my machine if I ask rpm to specify which package contains
/usr/sbin/in.ftpd I get..
[root@weasel /root]# rpm -qf /usr/sbin/in.ftpd
wu-ftpd-2.6.1-6
If you install this package from your CD with rpm then you will fix it.
