As you said, a zombie process is already dead. It takes up no room in
the process table and can essentially be ignored. This process entry
will eventually be removed by init

Dear Dowe,
Nope, my laserjet toner cartridge is fine; just replaced it this past
January, in fact ... and, since I "share" this printer i.e., when I'm
not using my Linux pc, I disconnect it, and then re-connect it to my
Windows pc ..., I know that it's printing "just fine", thru my Windows
O/S. However, thanks for the idea!
Sincerely,

Strange problem with esd though: my sound comes out way too fast, like in

Complain to whoever your distributor is, or recompile passwd correctly
yourself. If the utility does not do what it is documented to do, then
it or its documentation is bugged. Either way, a correction is

I guess it makes sense for programs that use graphics libs to stick the
runtime libs with the other ones. For example if I have a shared lib for
GTK/TK/Athena or whatever and I install a program that uses it, then it
doesn't have to install it's own version. (though w/ GTK it probably should
since different versions don't play nice) Or, fonts, if a program has it's own
fonts, but they could be used elsewhere, why not put them with the rest of the
fonts...

I am installing Red Hat 6.2 and need to buy a laser printer. Does anyone
have any suggestions as to what printer I should get? The Red Hat
compatibility list suggest many possibilities, but I am looking for an
inexpensive printer that is easy to install and is known to work with
6.2
Thanks for any help

Subject: Problems installing Linux on SGI 320
Date: Mon, 10 Apr 2000 14:35:01 GMT
Hi all,
I'm trying to install RedHat Linux 6.0 on my SGI 320
but I can't go more than the 2nd floppy. I'm following
the istructions indicated in www.linux.sgi.com.
Here is the configuration of my 320:
CPU single PIII 500 Mhz
RAM 256 MB
HD SCSI 9.1 GB (the 1st partition is a NTFS,
the 2nd is a FAT)
SCSI Qlogic 1080
PROM 1.0006
- FLOPPY BUILDING
Downloading of rh60.initrd.img and rh60.rescue.img,
and renaming them in initrd.img and rescue.img. After
that downloading of the remnant files.
-> Floppy1 (format -FAT- and copying arclx.exe and larc.exe)
-> Floppy2 C:> rawrite
C:> enter disk image source: initrd.img
C:> enter target diskette drive: A
C:> Please enter a formatted diskette .....
C:>
-> Floppy3 C:> rawrite
C:> enter disk image source: rescue.img
C:> enter target diskette drive: A
C:> Please enter a formatted diskette .....
Controller has failed
C:>
-> Floppy4 (format -FAT- and copying f4jul28.tgz)
- LINUX INSTALLATION
1. creation of two boot settings (one with arclx.exe and one
with larc.exe); I tried both of them.
OSLoader: arclx.exe (or larc.exe)
OSLoadFilename: /la2210.vw
OSLoadPartition: Floppy1
SystemPartition: Disk Partition no longer present
OSLoad Options: root:/dev/fd0 load_ramdisk=1
I tried also with
OSLoad Options: root:/dev/fd0 load_ramdisk=1 init=1
but without positive results.
2. Insert Floppy 1
3. Start System
The system starts to work and begins to load the first
floppy: everything is recognized (USB keyboard and
mouse, ql1080, Disk, etc.). In the final part of
the list that appears (black page with the
penguin Tux in the upper-left corner) there are these
messages:
Partition Check:

press ENTER
<I insert the floppy 2 and press ENTER>
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 2000 blocks [2 disks] into ram disk... done disk #1
Please insert disk #2 and press ENTER
<which second floppy???? I tried to insert the other disks (one
for each attempt) but the result is always the same>
Loading disk #2... done.
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 52k freed
Warning: unable to open an initial console.
Kernel panic: No init found. Try passing init=option to kernel.
<at this point I have to reset the SGI 320 because I can't
go on>
Who can help me? Thx in advance.

I suggest you just generate new ssh keys. (Well, and re-install everything
from scratch. Minor details.... ;-) ) Telnet is inherently insecure.
Suppose that you start using telnet. Anybody on a system between the one
you use to log in and your Linux box can then snoop your password. That's
bad, even if you think your system only accepts connections from a
specific IP address. You might have goofed on the configuration, or the
password might be usable in another way (say, if FTP is running).
As to restricting access to specific addresses, there are several tools
that will help you do this, including:
- TCP Wrappers. Used in conjunction with inetd, TCP Wrappers lets you
restrict access to specific services to machines that meet specified
criteria. This is why I said in a previous post that removing inetd
might not be such a great thing to do. TCP Wrappers is standard on most
Linux distributions.
- xinetd. xinetd is a replacement for the combination of inetd and TCP
Wrappers. IMHO, it's better for a host with two or more network
interfaces, because it lets you bind services to one interface but not
another. So if you only need to log on from systems on your local
network, for instance, you can bind ssh or telnet to the local
interface, and your system just plain won't respond to login requests
from outside sources, even if they spoof their IP addresses.
- ipchains. You can use ipchains to set up a packet filter firewall to
block access to certain ports (like ssh or telnet ports) from all but
specified IP addresses. The firewall site to which I referred you
earlier (http://linux-firewall-tools.com/linux/) has a tool that will
generate an ipchains-based firewall script to your specifications.
Personally, I recommend using ipchains AND either xinetd or inetd with TCP
Wrappers. That way, if a security bug exists in one package, you're
protected by the other. Also remember that most of these tools work partly
or completely on IP addresses (and sometimes hostnames), which can be
spoofed, so you shouldn't assume that you're safe from attack just because
you've blocked services. If a service is running, you're vulnerable.
(xinetd can be better in this respect if you can bind a service to an
internal network's network interface only.)

/proc is a "virtual" filesystem. It represents information on your system.
For instance, /proc/interrupts lists the IRQs in use, and /proc/pci lists
information on PCI devices. Most of these files have 0 length because the
system generates the information dynamically, so it'd be misleading to
give them sizes. /proc/kcore is a representation of your computer's memory
(I bet you have 256MB of RAM, right?).

I don't know. Mine are dated correctly. Is your system clock correct?

Which you have to do if you want to install/deinstall any software
on a PC/Mac. Sort of an inherent assumption when using a PC/Mac.

You do have a point. Assuming that it's well known that Win9x and Macs
are are _PERSONAL_ computers and never should be used in multi-user
settings, it would be unfair to blame the OS for not being what it never
claimed to be.

What did you have in mind? Off the top of my head, I know
about:
Python
Modula-3
Scheme
Lisp
BASIC
Smalltalk
Java
Ada
Logo
Tcl
C
Objective-C
Eifel
Haskell
COBOL
Logo
APL
Rebol
bash
Perl
Awk
[and many, many more]
I've only used about half of those, but the last time I looked
the rest are available for Linux. Some of those languages are
available in several different implimentations.

Really? You go to MS own page to get the word on low TCO? You don't
