Get the source for rlogind and modify it, e.g., pass the remote
user as $REMOTEUSER in the environment. (This is already true for
SGI IRIX 4.0). You may also need to modify login as it usually destroys
the environment. It is not too difficult, provided you can get
the source to a login/rlogind.c similar to yours.

(chiming in to cause trouble)

Sure.  Circa 1985-86, Hanscom AFB, Bedford, MA.  I stopped by a local officer's
cube to check a terminal (the harebrained AF types always managed to hit the
"terminal reset" key and blow their baud rates out of the water), and while I
was there a secretary described a problem she was having with her PC.  She was
following the directions concerning backup of her DOS floppies (making copies 
and stashing the masters somewhere), but every time she closed up shop for the
night, shut down the machine, and went home the copy went bad, and was unboot-
able the next day.

I asked her to start up the machine so I could observe the behaviour, and she
promptly opened a regulation 6' high steel double-door case, then reached in 
and popped her DOS copy diskette off a small magnet on the door.

Can't recall the secretary's name, but yes, "it happened to me."

Hanscom was rife with really weird people.  One of our operators was once told
to check some unknown tapes to see if they contained any data.  We became a 
little suspicious when he managed to test ~100 tapes in 10 minutes, so we 
asked him to describe his method.  He held up one tape (from pile "A") and
another (from pile "B"--the "contains data" pile) and said "see, this one 
(from pile "B") is heavier, so it has data on it."

Oy.

I have the following relatively simple problem: I manage a bunch of
workstations that belong to the Computer Science Dept. at a small
college.  For various reasons it's convenient for these machines to
get their password database served (via NIS) from a machine that
belongs to the IS department, and which has a super-set of the users
that should have access to the CS dept.'s machines.  Home directories
are served from a CS server, so anybody who has an account on the
IS machine could log in, but unless they are valid CS users won't
have a home directory.

Now what I'd like to do it prevent people without home directories
from loggin in entirely.  A couple of simple hacks come to mind...
i.e. have .cshrc and .login files in the root that log people off
immediately if they're not root, but none of them seem particularly
secure.  Anybody know of a good way of doing this?

Depending on where IDLE field is coming from, it might not be wise to do
this.  If, for example, IDLE is coming from the results of a "w" command
(I'm on a sun), it reports the idle time of the "terminal".  It is possible
for the terminal to be idle, but processes started from that terminal that
are not interactive to be active.  Its always wise to kill any children 
before the parent if possible.

I do agree. In my CS school we use around 150+ X terminals on a single  
ethernet segment mostly for edit/compile/run/debug cycles. The servers are  
4 MIPS RC3330 with 128 Mb RAM.
Everything is really running smooth except we have do double up (maybe  
more) the number of mbufs in the kernel (3330 are said to be workstations,  
not servers, and some kernel config had to be modified).

The network load is really correct (anyway not more than a quater of the  
bandwidth) except when booting simultaneously all the X Terminals after a  
power failure. This completly stopped the network from operating. We had  
to do an orderly start up of the terminals 8 by 8.

Motif is really eating up most of our servers memory. A program like xrn  
may gobble up to 2.5 Mb of memory. 4Mb SIMMS are now cheap, buy memory !!!  
The limiting factor is *really* memory.

I do think that in *OUR* environment a single R3330 way be used  
simultaneously by 30-40 X Terminals with really correct response time.

Games and many animations tools should be restricted. They really lock up  
the machine, filling mbufs, ethernet bandwidth and slowing down everyone.

We are waiting for two Milleniums (R4000 SC) machines with 256 Mb RAM, and  
hope each will serve around 80-100 X Terminals.

I am trying to apply the fix to libc.so.*.*.* so that it will use the
DNS resolver routines to do hostname/address lookups via the Domain
Name Service.  I am able to use DNS after the fix but I can't start
OpenWindows.  It keeps giving me an error message saying something

the hosts file but the hosts file does not seem to be used for anything
after the DNS fix (everything uses DNS).  This puzzles me because
the other guys around here who have performed this fix have not had
this trouble with localhost.
    The main difference between the machines is that the one with
the problem is using olwm (OpenLook) and the others are using mwm
(Motif).  They are all using SunOS 4.1.1.  Does anyone have any ideas
as to what is going wrong or what I should take a look at to fix the
problem?

Does there exist any "good" configuration management software out there.  I
know about RCS/CVS and SCCS.  What I'm looking for is something that can run
on all unix platforms.  I am not concerned about concurrent access to elements
of the libraries, so CVS is at no real advantage for that reason to me.

I would like:

  Runs on all Unix platforms.  In particular we have SGI's, RS-6000's, and
  Sun 4's.

  I don't want software that is dependent on particular versions of system
  routines, like GNU diff, etc.

  I'd like something that supports the concept of a named library, so one
  does not have to be in the parent directory of the library (as in SCCS)
  or fake it by means of soft links.

Any comments and suggestions on a configuration management system that you
like is much appreciated.

I have this problem with my Dallas Fax v32bis modem as well.
I believe tip is sending a carriage return (or some other)
character to the modem as soon as it sees the carrier detect.
With my modem (and all other Hayes-compat. modems I've ever used),
this causes the modem to abort the dial/connect.

With my old 1200bps modem, this didn't happen -- I think because
it didn't show carrier detect until it also said "CONNECT".  My
new 14.4Kbps modem shows carrier whenever it sees one, rather than
waiting until handshaking is done.

I have no idea how to fix this with tip.  It's annoying, however.

What are these "sr" and "ss" fields?  I don't see these in the
man page for "tip" or for "remote" under SunOS 4.1.2.

I didn't seem to get any errors by adding them, but nor did they
help any.

As presented in a previous post: would a cron-job of anyone on the system
modifiying files in any way (by just reading a file you modify the
directory, remember?) not interfere with the dump going on?
Don`t tell me there's only one job at a time forked-off by cron. It's not.
And what about at and batch?

This person would probably use script which does shutdown before dump, 
wouldn't he?

   Can you provide information about when and where this happened? Did you
   personally observe this? I'd like to find out if this has more than urban
   legend status...

A similar thing did happen to a man who worked for a related department to
mine.  This was back when PCs were just starting to arrive on campus.  He
said that he had just taken a third box of disks over to a secretary who
had been having problems with her floppy disks going bad on her.  He had
originally set up her computer for her, left a box of 10 disks with her,
and firmly impressed on her that the disks were vulnerable to magnetic
fields and that she should not leave them on top of the monitor, computer,
under her phone, etc.  She called up the next day and complained that the
box of disks he had left her was "bad" and they didn't work.  This was
during an era when such occurances were unusual but not unheard of, so he
mailed her a second box of disks through campus mail.  When she called
again to complain that the box of disks was bad, he got suspiscious, and
started asking questions about how they were bad.  She said, "They work fine
once, and then go bad."  He asked her if she was doing any of the things
that he had told her not to, and she said, "Oh, no, I take very good care
of them, and keep them away from the machinery.  When I am not using them,
I tack them on my corkboard."

CompUSA (SoftWarehouse, or who ever they are today) has 3M and Sony

For me $15 a piece is low enough for the extra peace of mind.

  I once did something somewhat similar. At work I had a PS/2 model 60 (Oooh!)
with an external 5 1/4 drive. I put my phone on it to free up space until
someone mentioned that whatever disk was in the drive would get zapped when
the phone rang. I moved the phone.
