Well, that or change how screen works.  We're going to have to do something
like that for the terminal server, though, so making some changes to how the
ptys get used is more likely.  

Probably we'll have some inner telnet limit so that we can just open up all
the ptys, and have that other telnet limit handle incoming telnet sessions.

I do not want my number of sessions limited.  Earlier today Steve (srw) 
sent me a telegram because i was taking up 3 ttys.  here's the breakdown 
of what each tty was doing:
1: I was installing a program, which is huge, and is taking several 
hours, i guess i could have run it in the background, but it was too late 
to start over when i realized that.
2: I was having a very important conversation in party (not just "idleing")
3: the last tty was non-existant but the `users` list showed i was taking 
up a tty.  I think i twas left over when my telnet windwo closed with a 
general protection fault.  Anyway, I ran `ps -x` and i didn't see any 
processes for this tty.  EVENTUALLY (after 30 min) it left, but i didn't 
know how to kill it.  Usually sending a telegram to a "zombie" login 
kills it, but it didn't work this time

But until grex gets a better processor, a lot more ram, and a T3 
connection, we will have to deal with slowness, and do the best we can.
Perhaps a note in the MOTD for a few days notifying users to "take 
responsibility for themselves" with htis matter, and make sure that they 
are not hogging pty's if there are over 72 people on Grex.  (or however 
many people)

If you start something in forground, and suddenly wish it were in background,
do ^Z to suspend it, and "bg" to throw it in background.

Jan -> yes, I am aware of that.  But I was using Makefile, and I needed to 
catch all the messages that the compiling gave me.  It was too late
to re-direct the output into a logfile.  If i was in party, reading the 
text of users talking it would be very hard to get the messages from the 
compiler.

I have quite a bit of sympathy for Ryan's cause in this case. I have also 
wanted to compile big things from time to time. Often there simply is no
non-busy time. Weekends are the best bet, but sometimes you just can't wait
that long. Grex is pretty busy almost all the time.

One of Ryan's ptys really was unused, as he claimed. I just hadn't spotted
that when I sent him that "tel". I have sent mail to numerous users who are
found using multiple ptys when the system is full, asking them to consider
limiting themselves, but with the understanding that there is no rule 
(at least today) against it.

Pretty much anybody can compile programs and place them on their own account.
Couple notes:
  - we don't recommend that you run programs out of other people's
    directories.  Various nasty things could be done to your account.
  - compiling puts a lot of load on Grex.  Try to be efficient.
  - compiling your own versions of telnet, ftp, etc, won't help you get
    access to services restricted to members.  Those restrictions are built
    way way further down inside the kernal of the system.

Yup, see item 95 in this conference, for a discussion of exactly this.
(By the way, it should have given you 5 minutes from the warning to when it
closed your second session.  It only closes down multiple sessinos when there
are 64 or more people logged in to Grex.)

I totally gree that people sometimes need to be limited to their sessions on
Grex.  Especially when I am waiting in the que for 20 minutes just to check
my mail at 1am in the morning  ;p  Though I know that I am not a prime example
of good with two logins (jiffer and stpaulgl)  [though ?I usually only use
the stpaulgl login wheni knowI am ftping or trying to do
