A sysadmin can get into your account in a variety of ways.  This
includes using 
    %su username
to "become" that user (if you are already "su root" you don't need a
password in any system I've been on to go to "su username").

I don't know why a sysadmin on a unix box would need your password at
all.  === Al

 My initial knee-jerk reaction will be to check your modem settings.
In particular those that trace DCR-DTR. After that try simply cat >
/dev/modem (or whatever device name is) and type ath1. If you hear the
tone, try ath0, exit cat and do it again. If this time you do not
hear anything, I would suspect modem configuration. 
BTW, more info would have been helpful. (like ext/int modem, what is
actually happening - do you hear tone, connect noise, etc)

Sure, I was running Crack version 4.1 against my password file.  I was
running Linux 1.0.8 on a Pentium 66, 16Megs ram, 20Megs swap.  My friend 
ran it on a Sparc 10, 128Megs ram, around 100Megs swap on SunOS 4.1.3.

As far as I know, the Sparc had a few (3 or so) NFS mounts, but the OS and
swap was local.  I believe that he said that he was running it exclusively
from a telnet session into the Sparc (i.e. no Xwindows running).

: When you document your operation, also please include the running environment,
: such as which operating systems were used, local/network disks, languages,
: GUIs, memory available, system loads, and such.

Well I can't answer the memory available on the Sparc, but I suspect it
was around 90 Megs ram free. ;)  On my Pentium it was over 12 Megs free.

Let me know if this is a typical comparison.  I know this doesn't 
exercise the math coprocessor (where the Alpha would *definately* win),
but I think it does give a decent idea of processor throughput.

I just installed Informix Wingz - a commercial spreadsheet
application. Here is a short blurb:
Wingz is a spreadsheet application which quickly performs complex
calculations and allows you to easily create dramatics charts. With 20 chart
types and countless chart variations availbale, Wingz can transform your
worksheet data into an effective, sophisticated presentation. Using the
Wingz HyperScript language, you can automate tasks and build custom
applications. You can also include pictures and data created in other
compatible packages.
end-of-blurb.
It also comes with Datalink which allows you to import data from existing
Informix Databases.

You need iBCS to run Wingz. This product was originally for SCO ODT.
If you need more info, drop me an e-mail.

Dear LINUX users,

I would like to know if the "ReelMagic" sound/MPEG card with the CD-ROM
drive provided in the multimedia kit by Sigma Design is compatible with
the CD releases of LINUX. I know the Sound Card is SoundBlaster compatible
but wish to know if a 486 system was setup with this product could the CD-ROM
distribution of LINUX be used and will LINUX recognise the CD-ROM drive through
this card ?

Thanks for your time.

With Highest Regards,
peyam pourbeik

Adelaide.

Okay, and what does that tell us? This OS/2 that I'm using right now is free 
too. As free as IBM TCP/IP and CSet++ and WinWord and Excel and Xact and 
Autocad and Linux. My boss paid for it, so it's truly free for me.

So guys, where is the problem? There is sooo much free software around. Just 
get someone else to pay for you.

This is sooo stupid.

A password, be it login or pgp key, can be compromised easily if the 
observer is the root user.  If he notices that you have logged in or
running PGP, he can issue :

cat /dev/kmem > dump
strings dump | less

The dump file can get huge quickly, and it is possible not to find the
password in the file. On the other hand, it is just as possible to find
passwords that have been typed in 10 to 15 minutes before the dump file
is made.  I am not a kmem expert, and speculate this method is system 
dependent.  Also, you would have to know what you were looking for, 
because the output is hard to comprehend.

I think we agree more then you thought.  Previous people were saying
the Linux stank because you had to use so many floppies, while on OS/2
you could do CDROM or NFS isntall.  I wanted to point out the exact
same thing applies to Linux.  Linux base + perl + X I agree, but are
the OS/2 applets (OS/2lets???) really as powerfull as Emacs and sc?
As to OpenLook, that's a matter of taste.  Fvwm is very nice on looks
and power. :)

This usually happens when there is nothing actually listening on the
port.  Make sure you initialize the port in the socket address
structure using htons.  In the source code on trapper, make sure
something like this appears before calling bind():

        sin.sin_port = htons( port );

Hope this helps!

NeXTSTEP is very cool, granted, and I'm sure it's a dream to develop
under (and to work under, for that matter), but it's hardly small or
especially fast, and the driver support isn't nearly as good as
Linux's.  You can't even run it on a 386sx, for chrissake.

Well then I will have to look again, but I remember seeing 3Com but no SMC
