But the security of the 'mainframe' *is* compromised! You've just
given a intruder one of the the most valuable tools he/she could ask
for, unrestricted user level access to your 'mainframe'. They may not
have root right away, but we all know that there are tons of holes on
machines just waiting to be exploited once you're on the machine.

>If a cracker can spoof the system via

Not true. By running term, you've created a completely trusted channel
between your Linux system and the 'mainframe'. The 'mainframe' trusts
your Linux system to protect it from 'bad people' on the Linux end. If
I can break into the Linux system somehow, I have a very good chance
of exploiting that trusted channel to get onto the 'mainframe'. Even
if it's a very secure 'mainframe'.

BTW, this works in the other direction as well. Your Linux system is
counting on the 'mainframe' to protect it from attacks from other
users on the 'mainframe'.

Like I said before, term is a great tool. But sysadmins of machines
whose users run term, should understand that this is another
vulnerability that they're going to have to deal with. I think it's a
risk that can be managed by educating and then trusting your users,
but obviously different sites have different tolerances to this kind
of risk.

Subject: Intel Ethernet Express - need advice on checking it
Date: Fri, 21 Jan 1994 19:22:04 GMT

Can someone fill in a couple of gaps in the HOWTOs for me? I have a machine
with an Intel Ethernet Express in it. I got the alpha driver for this animal,
and rebuilt a 99pl14 kernel to use it - i think i did it right, it got compiled
and included in the library. So now, I start trying to install NET-2. It doesn
work, of course, never gets past "ifconfig eth0". What bothers me is that I have no
idea if Linux is *finding* the board at all. is there *anything* i have 
to do apart from comoiling support in the kernel? no configuration? no telling it what 
interrupts to use and all that? there are cryptic comments in the Ethernet HOWTO about
passing things in with lilo, but i dont follow that. where does such info go?

sorry to appear dumbo, but the HOWTOs are so good that they forget a few small
conceptual matters...

is there a generic tool for testing if Ethernet cards are alive? *without*all the net stuff.

This can be done very easily with even an 8088 and one of the NOS packages for
DOS.  JNOS would work very well.  It has SLIP support built in, so you could
link the two machines easily.  JNOS even has _good_ documentation on how to do
this!

In the recent "dream machine" thread several posters suggested
Pentium.  However, the most rececnt Hardware-HOWTO doesn't make
any reference to this processor.

So what's the scoop?  Will Linux run on Pentium or not?  Does
anyone have any experience based recommendations?  I've just
been told by my management to put it a requistion for a new
computer and must choose between Gateway 486/66 and P5.

        Initially I felt that ctrl-alt-del sort of violated the
idea that  root should be the only person to reboot the machine.
This was after using Linux for about four days (read: getting it 
installed, working and finding all the boot & login scripts - I
was feeling like God).

        Some experience now makes me think that ctrl-alt-del 
working is OK, since I've had to resort to it a few time while 
getting  a piece of software that likes to lock the console to
work.

Once again I will be hosting an X-For-Intel-Based-Unix BOF at the X
Technical Conference.  The session will be this monday afternoon.  Come
join us.  XFree86 will, of course, be a hot topic.  But there will also
be representatives from some of our peers on the commercial side of the
house, including NCR, MetroLink, and X Inside, that I know of.  Hopefully
some SCO, Novell, QIS, and other folks will be there as well.

Last year we had a grand old time, discussing lots of interesting topics.
Hopefully we will do the same this year.  Expect at least one major
bombshell.  Come one, come all.

I'll be in town for the conference from Sunday afternoon until Wednesday
or Thursday (depends when I can get a flight out; work calls...).  Hope
to see you there.

A question has come up re. which shell(s) should be the focus of the book.

Subject: HELP!  Added DAT drive to system and can't access
Date: Sat, 22 Jan 1994 02:56:27 GMT



Hello everyone,

I've just installed a WangTek DAT drive to my system and am having
problems having Linux recognize it.  On bootup, the kernel and
controller card recognizes the drive, however, when using /dev/rmt0
as well as /dev/nrmt0 with tar (tar {c,t}vf /dev/<n>rmt0) gives no
success: it reports that there's no such device.

Here are the vital stats:
        Running latest Slackware (pl14)
        Adaptec 1520A SCSI Controller
        Quantum PD1050S hard drive on SCSI ID 0
        WangTek 6130HS DAT Drive on SCSI ID 2

I've read through the SCSI-HOWTO doc and true enough, /dev/<n>rmt0
has major number 9 and minor numbers 0 and 128, respectiviely, as well
as being a character device... so that looks correct there.  I've even
tried making a new generic scsi device entry:
        mknod /dev/scsi[0-6] c 21 [0-6]
with no luck either.

Can anyone give me a hand here?
Thanks,

I wasn't trying to imply term was the only way these problems could be
created, but term makes it easier for users to set such things up, often
unwittingly.  This is where it is a possible security problem, because the
users may not have the knowledge to set such a thing up without term, or
may not think through the consequences of what they do.  I didn't mean to
imply that term added any new security problems were none existed before.
But just because it doesn't doesn't mean it should be ignored as not being
a possible security problem for an especially security conscious network,
such as one behind a firewall.

SLACKWARE 1.1.1 (Linux 0.99.14 ) ON CD-ROM - ONLY $9.95

I have crated a CD-ROM that contains Slackware 1.1.1 (Linux 0.99.14 ).
Slackware was FTPed from ftp.cdrom.com only 5 days ago. You can install
Linux directly from the CD-ROM. I installed Linux on my system in less
then a hour.

The cost of the CD is only $9.95. ( Yes its $9.95 ). There is a reason
for the low price,  I do not have a interest in making huge profit out of
free software that so many people spend all there time working on it.If
you cant afford to pay this amount  E-Mail me and I will send you a
free CD.

Installing Slackware ( Linux ) is very very easy, I have included few
pages of instruction for new users to Unix. If you still need any help
on installing you can call or E-Mail me.

Order taking, shipping, customer support and all other logistical problems
have been taken over by Christina and I am out of it ( Thank god :-) ) .
If you would like to place an order please call Christina at 1-800-363-2083
(FAX 1-416-922-5597 ) or E-Mail Christina at christina@jana.com.

Summery : This CD contains Slackware 1.1.1, that can be directly installed
from the CD. Also this CD contains .ZIP'ed versions of all the Slackware
disks so you can put this on your BBS. The rest of the space is filled
with MS-DOS and Windows files (About 400 Meg ) Allmost all of them are new
files with file.bbs ready.. If your local BBS does not have Linux on-line
get them this CD.

Cost :
U$9.95 Per CD
U$4.95 Resale ( Min 25 Disks ), U$3.95 for 50 Disks.
U$3.95 for any Linux user groups/schools (Min 25 Disks), U$2.95 for 50 CD's.

Shipping : Shipping will began this weekend and all orders will be shipped
the same day we get the orders. Shipping charges are $4.95 Canada $5.95 US
and $9.95 World.

Payments : VISA and Master Card, Cheque.

Note : If your are a subscriber for the Jana CD's you will get this disk
as part of your subscription, so do not order this disk. If you have any
questions, change of address or address verification problems please E-Mail

Reply-To: J.Cancela.bra0118@oasis.icl.co.uk

I'm afraid *THERE IS* a USL based UNIX with Chorus microkernel
out there in the market. ICL plc has developed a
massively-parallel SPARC based system running an implementation
of SVR4.2 with Chorus microkernel. This was part of an EC funded
research project. This system can go up to 127 CPUs and deliver
around 5000 tps in its largest configuration, and it's 






         specialized in running RDBMS backends.
         
         Besides that particular instance, SVR4 roadmap's next big step is 
         to introduce Chorus microkernel. Limited resources, priorities and 
         the recent handover to Novell's hands don't allow for a quick move 
         in this direction. Other major vendors have already announce their 
         intentions to move their UNIX variants to microkernel 
         architectures. Multiprocessing hardware definitely gets a huge 
         benefit out of it! 
         
         I definitely believe you shouldn't underestimate this trend in the 
         UNIX architecture...
