it has nothing to do with linux.  you can run term on almost any
machine you want.  this case can only be exploited if the person
running term allows it.  also, term has no concept of '.rhosts',
and runs entirely as user level code.

again, it has nothing to do with linux.  this isn't a problem
with term, but a problem with the 'security' you put in the
firewall's router.  i can write (but i wouldn't, i have the
code somewhere already) a program to do exactly this thing,
and do it better than term does.  (actually, it's hard to set
up term to do the above.  it runs over serial lines, generally)

if your system gets broken into 'via' term, then term wasn't
needed to break in.

It can be simpler than this. If you look at the man page for
term clients, you'll see that they have a -t option which
allows you to select alternate term sockets, i.e.

trsh -t 1

will connect via .term/socket1 instead of the default
.term/socket.

Now how do you make term itself use an alternate socket?
The man page doesn't say but it is actually the last argument
to term. I.e. to start term using .term/socket1, do

term 1

On the other hand Olaf's suggestion avoids the embarrassment
of accidentally uploading files to another persons machine by
forgetting the -t option.....

UNIX means much more than /unix. Linux does not. Thus your statement is

And unfortunately its neither the first time nor will it be the last time this
has happened. But it is a distribution of linux problem not a linux issue -
and nobody has every claimed the distributions are GPL - much is BSD, or
assorted author copyrights.

As some may have discovered, there is a flaw in the December 1993 
InfoMagic Linux CD involving links between the sunsite and tsx-11
archive images on the CD.  I called InfoMagic about this and had 
my call returned by Kim at InfoMagic this morning who said that they
are aware of the problem and are already shipping replacements out
to those who ordered the CD.  If you've ordered one of these you 
might want to call and verify your shipping address with them.

Just wanted to post this to let everyone know and commend the 
folks at InfoMagic for their excellent "customer-first" attitude!

Of course you best use a Z8530 (SCC)-based board instead of either
the Baycom 'solution' or a TNC.  It costs less than a TNC and provides
better and easier control by the software.

I realize I may not have been sufficiently clear. The disks are foratted

They have bad sectors and that is not a problem for DOS. It is a problem

If you mean highest quality output, use TeX and the newsletr macros,
supplemented with your own macros as needed. This assumes you don't
mind programming.

If instead you mean quick and dirty wysiwyg output, use andrew's EZ
multimedia editor (ftp sunsite.unc.edu:/pub/Linux/X11/andrew for v 6.1
or ftp tsx-11.mit.edu:/pub/linux/packages/TeX/Milieu for essential
parts of an old 5.1 version).

Subject: More help with SLIP/DIP please ?
Date: 21 Jan 1994 16:31:12 GMT

Thanks for the suggestion on the SLIP/DIP problem.
I'm still not there though.  A couple of specific
questions.  Why didn't my SLIP server tell me its
IP address, like I see in examples?
Why did I get further by by typing:
"remote" followed by the IP address it gave for
my address this session ( as suggested by 
someone) ?

Now I get to:

        elvex>slip

        Entering SLIP mode.
        Your IP address is 129.105.9.83.  MTU is 1500 bytes
        Header compression will match your system.

        [ Back to LOCAL mode. ]
        DIP> local 129.105.9.83
        DIP> remote 129.105.9.83
        DIP> mtu 1500
        DIP> mode SLIP

As always suggestions and help greatly appreciated.

In what way is it worse to let user A run term than to let user A log
in at all?   In either case, (a) A has access to the machine at the
user level, and (b) A can let B have access to the machine at the user
level.  I would prefer to rephrase your summary as follows:

   Letting users log in is great.  But sysadmins of machines who let
   users log in should understand that this is another vulnerability
   that they're going to have to deal with.

Ben,

I have no intention to subjecting my users (mostly students - you know
the kind that stare at the screen for multiple hours at a time. ;-) The 14"
mono monitors suck! I'm trying to find something inbetween the 14" and
the big 19" and 21" greyscales (at $1000 apiece).

OK, now help me out. Where did you see these *GOOD* greyscale monitors?
That $150-200 price tag is in the range I'm looking for. What size were they?
In fact I'd like to drop in high resolution 17" color monitors. I can't justify
the cost though. I'll ask again:

Does anyone know of a SVGA compatible 16"-19" greyscale monitor (new) that
cost less than $400 or so?

Subject: How to be a dial-up SLIP/PPP *server*
Date: Fri, 21 Jan 1994 20:49:50 GMT


Hi All...

Here's what I'd like to do (ideally): User X calls up my Linux box, and
logs into his personal account that has a custom shell.  Then user X
enters a command like "SLIP" or "PPP" which causes invokes all the
appropriate programs to turn his connection into a SLIP or PPP connection.
When the user is finished he/she simply hangs up the connection.

So, is this feasible?  I want people to issue the command from within
their account for billing/tracking reasons.  Is this a problem or do I
have to set up special SLIP accounts for people?  Anyone doing something
similar and care to share some info?

Is there a SLIP FAQ?  (I suspect there is and will look for it right now) 
Any and all advice greatly appreciated!

Subject: Advice on multi-serial cards wanted...
Date: Fri, 21 Jan 1994 20:58:33 GMT

I currently have an STB 4-port serial card installed.  It is an excellent
card and I highly recommend it.  Now we are about to add more modems to
our BBS.  

I know I can add another STB card for a total of 8 ports, but I don't think
you can then add a third STB later - or can you?  See, we may have to have
more than 8 modems before long.

If I *can* have 3 or 4 STB's in the same box then that's fine (I like them
a lot).  If not, can anyone recommend a good 8 port card that will
co-exist with the STB that I already have?

Along these lines... my current STB card is set up so that each port uses
a different IRQ.  If I were to place all 4 ports on the same IRQ, will
this degrade performance at all?  Is it feasible to have 3-4 STB's with
each *card* set to a unique IRQ (I know I have 4 IRQ's available).  What
would the performance be like?

My users generally connect at 38K, do a lot of telnetting/ftping/etc. 
It's highly unlikely that all 8-12 lines would be downloading files, but
it is a possibility.  I need each port to be capable of 38K, have full
modem control, etc.

Thanks in advance for any and all suggestions.  I'll summarize if desired.
