Heh, this reminds me of an article in JIR[1] back in 1993 about a great
new data compression algorithm. Basically, you take the data, view it
as binary, throw away the 0's as containing no information, count the
1's you have left, express *that* as binary and repeat -- until you're
down to a single 1. Reportedly they were still working on the
decompression algorithm.

research journal, published at MIT. I have no idea if they're
still around.

Dear Readers,
I run Slackware 4.0 on an old 486DX machine with 16meg of ram. At the end
of the booting up messages I get the following error message:
neighbor table overflow
It does not seem to cause any problems. By the way, I am using the 2.2.9
kernel.
Does anybody know what this message means. I looked through the archives
of Usenet, but I did not find anything that gives me a clue.
Many thanks

Thanks for responding Dan, as I said, brute force experimentation... Any
ideas where I would find a restricted shell for Linux? The functionality
does not appear to be built-in. I've tried searching for it at a few
"comprehensive" linux sites, but no luck. More leads or specifics? Thanks
in advance.

Subject: Re: Is there a way to mount a samba share as a directory?
Date: Wed, 01 Sep 1999 08:31:04 GMT
I've eventually got samba working in my machine and i have now got my network drives
(on windows 98) mounted in Linux. To do this find the name of the computer which has
the drives you want to mount (i'll call it parasite). And you now have 2 options:
* Add it into the /etc/fstab file
or
* Just mount it from the command line.
OPTION 1
===========
edit the etc/fstab file (within emacs)
and add the following line:
\\\\parasite\\c \mnt\network\c smbfs user,no auto 0 0
NOTE: You must change your computer name and shared resource with \\\\parasite\\c (you
can view them by typing smbclient -L <name of computer>. You must also make sure that
your mount point (\mnt\network\c) is also made. Just create a directory for this. Then
to start the mount just type at the command prompt:
mount \mnt\network\c (or what ever your mount point is.)
OPTION 2
===========
to start a mount from the command prompt without having to change the /etc/fstab file,
type the following:
mount \\\\<computername>\\<shared resource> -t smbfs /<mount point>.
See above for more info, if you need any other help email me: [EMAIL PROTECTED]
I hope this is of help to you.

Actually this is pretty old stuff. NTFS has supported alternate data
streams since version 3.1. To play with them you could try:
C:\TEMP>echo default > file.txt
C:\TEMP>echo alternate > file.txt:alternate
C:\TEMP>dir file.txt
[M-x snip]
31.08.99 22:18 10 file.txt
1 Datei(en) 10 Bytes
676.115.968 Bytes frei
C:\TEMP>more < file.txt
default
C:\TEMP>more < file.txt:alternate
alternate
The only thing new is that MS is planning to use this for OLE structured
storage or something. A rather dumb idea if you ask me - not all the
world is using NT and this will be true for some time to come.

The stability thing won't happen as it is old stuff. OTOH the actual
implementation and integration with the rest of the system sucks badly
on NT up to version 4. For instance 'dir' won't display the true file
size but only the size of the default data stream (Explorer and File
Manager do the same). There is no way to find out whether there are
alternate streams at all (except writing your own tools using, of all
things, the backup API).
Well, MS (and others) already got security problems because developers
didn't know/care about this stuff. Basically the default data stream can
be accessed under two file names, without any stream spec (file.txt) and
with a stream spec of :$DATA (file::$DATA) which gets interesting once
things like web servers are looking at file name extensions to decide
what to do - foo.asp is different from foo.asp::$DATA to them. And to
top it off I just noticed that this special stream spec is case
sensitive but others are not - what a strange file system.

For an entirely internal to internal machine behind a firewall, I'm
inclined to agree BUT...
Of all the scanning that has happened to my box and the firewall at
work, I have seen port 23 hit with just about every instance. I have
rarely seen scans (other than whole nmap hits) that are port 1023.
My suggestion of disable all the remote abilities and get ssh put onto
that box and then only allow connection from certain address still
holds.

I wrote this whole thing out on one of these groups after I did it to a
machine at work. This is from what I did on a RedHat 6.0 box to make
the machine a logon box for people to get to their desktops at work from
but not be able to do anything on this box.
ln /bin/ksh /bin/rsh
mkdir /home/rbin
set the user up with /bin/rsh as his shell and set the home directory's
.login to have the line
PATH=/home/rbin
export $PATH
When korn shell is called via 'rsh' it becomes a restricted shell,
allowing very little. With this restricted shell, the user cannot
change directories and can only execute what you have in /home/rbin,
cannot alter his enviroments, and cannot do much of anything. Only put
the commands that this user is allowed to do there.
Word of advice, do not put things like /bin or /usr/bin in the path as
the user can get a full shell out of vi and other programs.
If you're more comfortable with bash, you may have to recompile bash as
the default bash does not have the restricted option in it.
http://mmg2.im.med.umich.edu/~kcheek/texi-docs/bash/bashref_toc.html#TOC77
That give you a starting point on the bash restricted shell. There are
similar documents for ksh, csh, etc restricted shells.
If you have more specific questions, please ask.

This may be part of your problem. I think that one controller only
should be in control. I too have a UMC motherboard which has the
original IDE/ISA primary port. However, with the installation of my
Promise EIDEMAX HD controller board the new BIOS which comes on it
over-rides the MB BIOS and gives that port all of the nice
characteristics of the Secondary IDE/ISA port on the controller board.
BTW, that board cost me about $25....a real value!

The drive size that you can utilize depends only on the new BIOS
onboard the EIDEMAX board (or equivalent). I can install up to four
128GB (yes GB!) hard drives, a master and slave on each of the primary
and secondary IDE/ISA ports.

This is probably a CD made by the hardware manufacturer containing

Hello everyone,
I face a problem during install StarOffice 5.1 on my RedHat 6.
The message come out :-
"An error occured while unpacking the file libsvx516li.so.
There is probably not enough disk space."
When this message come out, i immediately check for the space left,
it was around 180MB left.
Anyway, installation continue if i click on "Ignore" button.
But i try to run StarOffice, it just show nothing and cannot start the
program at all.
I search for the file "libsvx516li.so", it exist.
Before install, my hard drive space left is around 300MB, and i choose
"Minimum" installation.
I install from console, after the installation finish, an error
message come out :
libsvx516li.so : Bad CRC 5613fbld (Should be 23fa36b9)
I already try on different pc, but it still show the same problem.
Is it something wrong with the .tar file which i download from
StarDivision ?
Please advice.
Thanks.

I think XFree opens and uses the raw virtual console device rather than
/dev/tty7 or whatever, so that it has lower-level control of the
keyboard i.e. can set LEDs and can handle every press/release event
rather than just getting typed characters through the console vt102
interface. This is also how it keeps Alt-F1 and friends from switching
the VC out from under it (which would be bad, because a program running
on another VC wouldn't be expecting the graphics-mode state the VGA
card was in).

With VMWare, your Win95 will run on a *virtual machine*. The available
devices are also *virtual* devices and do not represent the actual
hardware in the machine, hence you cannot use the drivers you would
normally use for Win95 running natively on that machine.
Read the VMWare documentation more carefully. For example, the audio
card in VMWare is always an SB16, regardless of what hardware you have.

Ton.
