You get two guesses.


#29 of 74 by mcnally on Sun Jan 14 08:05:51 2001:

so where's your mail file kept, then, walter?


#30 of 74 by mdw on Sun Jan 14 09:19:20 2001:

Try
        !man getmailfilename mailfmt
        !cat /etc/mailfmt
I hope to update sshd with a version of openssh sometime soon.


#31 of 74 by ea on Sun Jan 14 15:05:11 2001:

So to fix the problem in ssh, just add a line to my .profile that says
setenv MAIL=/var/spool/mail/e/a/ea

or is there something else that I need to do?


#32 of 74 by remmers on Sun Jan 14 18:58:22 2001:

Since your login shell is .csh, you should put the line

        setenv MAIL /var/spool/mail/e/a/ea

in your .login file (note: no "=" character in the command).


#33 of 74 by lk on Sun Jan 14 18:58:43 2001:

That line should go in your .login (as csh is your login shell).
Those with sh/ksh variants should do:

        MAIL=/var/spool/mail/x/y/xyz
        export MAIL

Where xyz is their login ID.


#34 of 74 by lk on Sun Jan 14 18:59:54 2001:

Wups, remmers slipped in, but that's a good thing as I didn't look
closely enough to notice the extraneous "=".


#35 of 74 by ea on Sun Jan 14 20:29:03 2001:

Thanks John.  #32 seems to have fixed the problem.


#36 of 74 by i on Mon Jan 15 05:36:54 2001:

/var/spool/mail/i/z/i


#37 of 74 by ryan on Fri Jan 19 15:53:44 2001:

This response has been erased.



#38 of 74 by cmcgee on Thu Jan 25 13:05:49 2001:

I"ve had trouble dialing in for the past few days.  Last night I tried 5 phone
numbers, starting with 3000, and made two tries on each number.  


#39 of 74 by krj on Sun Jan 28 19:34:17 2001:

!df says the /bbs partition is 100% full.


#40 of 74 by gracel on Sun Jan 28 20:13:41 2001:

Just now, dial-=in connects but gives no response.


#41 of 74 by i on Mon Jan 29 00:15:40 2001:

Like #40, and about the same time this afternoon.  Trying another line
(-3554 ?) got me in okay, -3000 worked okay just now...

If I run the mesg command right now, it gives the error

    Unable to find your tty (ttyte) in utmp file



#44 of 74 by krj on Mon Jan 29 16:29:44 2001:

Another user in party had a similar message on the same tty (ttyte).
A scan of party should uncover the info which was dumped into party
at that time.


#45 of 74 by krj on Mon Jan 29 20:31:42 2001:

More complaints in party about ttyte.


#46 of 74 by aruba on Wed Jan 31 16:48:26 2001:

I notice Picospan and Backtalk sometimes disagree on which items are "new"
and which have "new responses".  For instance, when I join the DIY
conference in Picospan, I see:
/------------------------------------------\
| 7 newresponse items and 4 brandnew items |
\------------------------------------------/
and when I join it in Backtalk I see
/------------------------------------------------------\
| Diy has 31 items: 11 brand new, 0 with new responses |
\------------------------------------------------------/


#47 of 74 by janc on Thu Feb 1 04:56:40 2001:

Looked into that a bit.  Copied over Mark's .fixit.cf file.  I see the two
different messages too.  The items that the disagreement is about are all
ones that were marked "unseen" when Mark joined in October of 1998 and have
since had new responses posted to them, making them "new" items.  Doing
"read brandnew" shows 4 items, while "read newresp" shows 7.  However the
seven "newresponse" items, when you read them, show item text and all
responses - it doesn't think any part of it is old.  They sure act like
brandnew items.  I can't figure out why Picospan thinks 7 of these are
newresponse items.

My diagnosis:  Picospan bug.


#48 of 74 by krj on Thu Feb 1 06:19:25 2001:

The ttyte bug bit again tonight; Leslie was on that tty and could not
send me tels. 


#49 of 74 by aruba on Thu Feb 1 12:23:14 2001:

Re #47: Weird.  THanks for the diagnosis.


#50 of 74 by mdw on Thu Feb 1 15:20:56 2001:

An "unseen" item is treated as an item that is up to date (so "read new"
won't show you ancient crud), but for which you haven't seen any
responses (so if someone else responds to it, you'll see what happened
before in that item.)  Since it was previously "up to date", it's not
"brandnew", so a response to it makes it a "newresponse" item.  Since
you haven't seen any responses in it, it's going to look very much like
a "brandnew" item - it's the same logic in any case, so I can't imagine
why you'd want it to look different.  I suppose I could have invented a
3rd category, "newunseen", and perhaps even put more logic into the item
range processing so you could say things like "read new except
newunseen", but that seems a bit like overkill.  (Then again, hmmm....)

There's a balance here between being too complicated or too simple.
What I think is more important is the behavior for "d new" (or when you
join a conference) - the "X newresponse and Y brandnew" message.  That
should give you a notion of how busy this conference is, and what sort
of activity is going on.  Counting "newunseen" items as "newresponse" is
I think more fair than counting them as "brandnew".  That the
consequence of this is that "read newresponse" shows an item that looks
and acts much like a "brandnew" item is, I think, a reasonable tradeoff
for consistency's sake.

So, um, no, I don't agree this is a "bug" in PicoSpan, it's doing what
it was designed to do, and there are reasons why the design was so.  You
could argue that the design is faulty, and that "unseen" items ought to
in general be treated differently, and you'd not be alone.  Thing is, I
don't know of any graceful way to allow people to "catch up", and I'm
convinced I'd be catching flak no matter what solution I picked.


#51 of 74 by bdh3 on Fri Feb 2 05:43:22 2001:

No, mdw, I think you did it correctly as did janc.
I think Backtalk just breaks it out differently?  Picospan is telling
you there are 7 new responses to 7 items that you didn't ever read after
you joined and 4 new items since you joined.  Backtalk is saying there
are 11 items that you haven't read ( 7 posted before you joined and 4
posted since the last time you read).  

I think mdw has actually put quite a bit of ('human engineering')
thought into how people actually can usefully use picospan - something
that is extremely rare for a programmer to do (consider Micro$oft Word
for example).  'janc' has done a far better job than most as well
(although I wish there was a way to show the poster's login on item list
so I can easily click the box to forget all of that horrible 'bdh's
posts...)


#52 of 74 by bdh3 on Fri Feb 2 05:53:26 2001:

(For example of shitty coding, consider programs (such as WORD(thless))
that have a 'fonts' option.  How typically they display a list of font
names (only sometimes if you click on one displaying what they look
like) like I really am a typesetter and know the exact name of the font
I want to use (Personally, I really was and know far more about fonts
than I care to, but I am not your average (l)user).  How better the
interface would be if the 'fonts' listed a chart of pictures of the
various fonts, allowed you to click on one, and then a scroll bar to
select the available size (fixed or dynamic).  The average 'joe user'
doesn't need to know the 'technical name' of the font he wants to use,
nor really cares.)


#53 of 74 by eeyore on Fri Feb 2 06:00:34 2001:

I just dialed in, and got the message
"unable to find your tty (ttyte) in utmp file"

In fact, I got it twice.  Is this a major thing?


#54 of 74 by bdh3 on Fri Feb 2 07:24:08 2001:

eeyore    ttyte    216.93.104.37    Fri Feb  2 01:06 - 01:06  (00:00)
eeyore    ttyte    216.93.104.37    Fri Feb  2 00:58 - 01:06  (00:07)

It is rather odd. Perhaps a file system ran out of space and the utmp
(or wtmp) files are 'insane' and this error message is returning the
wrong string (or defaults due to nonexistant string) for the actual
error?


#55 of 74 by cmcgee on Fri Feb 2 08:45:39 2001:

I got that message several times this week too. But it did't seem to affect
my use of pine or bbs so I did't worry about it.


#56 of 74 by mooncat on Fri Feb 2 14:55:42 2001:

(actually, in the version of Word I use the individual fonts are all 
listed in their font so you can see what they look like.)


#57 of 74 by ashke on Fri Feb 2 15:53:07 2001:

(I agree with Mooncat, they started doing that on later versions of
Office/Word 97, and it's standard with Word 2000)


#58 of 74 by krj on Sun Feb 4 22:07:10 2001:

There are approximately 25 users on the system, but there's a telnet 
queue.  That doesn't seem right.


#59 of 74 by carson on Tue Feb 6 02:58:26 2001:

puzzled?  !tel xxxxx
tel: Panic - Unable to find your tty (ttyq5) in /etc/utmp
!                                                          


(say, is this unusual?)



#60 of 74 by i on Tue Feb 6 12:53:47 2001:

Got hangups on -3000 and -5041 dialing in just now.  (-3554 worked.)
The modems played a few second, then *click* - no "CONNECT...", no
"Welcome to Grex...".


#61 of 74 by janc on Thu Feb 8 01:26:37 2001:

Basically, the ttyte thing and the tel thing are signs that the utmp file
is messed up.  Some energetic staff member should fix it.  I'm not energetic.


#62 of 74 by pfv on Sat Feb 17 18:01:31 2001:

some dumb sunovabitch has managed to totally fill /a - please to clean this
up? My partfile is now trashed.


#63 of 74 by gull on Thu Feb 22 04:26:30 2001:

I'm getting "Authorization Failed" messages from Backtalk.


#64 of 74 by ea on Thu Feb 22 04:30:37 2001:

I'm also getting "Authorization Failed" from Backtalk.  Glad to know it's not
just me.


#65 of 74 by wh on Sun Feb 25 15:12:56 2001:

Bad participation file.  /a problem?


#66 of 74 by gull on Sun Feb 25 20:03:54 2001:

/a filled up yesterday.


#67 of 74 by krj on Wed Mar 7 02:55:34 2001:

There is a login queue, but there are under 40 users logged in.  
This seems to have happened to me several times today.  ??


#68 of 74 by eeyore on Wed Mar 7 03:25:29 2001:

I got a long queue, but it went from 22 to 21 to 10 to 2 to on.  In rather
rapid succession.  I thought that was a little odd...


#69 of 74 by katie on Wed Mar 7 04:35:00 2001:

Really bad lag right now.


#70 of 74 by krj on Sun Mar 18 18:17:47 2001:

resp:58, resp:67 :: today it's 35 users on Grex and a queue of 9.
This isn't the way the system is supposed to work: it's like putting up 
a unnecessary FULL sign.  


#71 of 74 by goose on Sun Mar 18 18:37:16 2001:

I've noticed this problem too.


#72 of 74 by scott on Sun Mar 18 19:44:53 2001:

It's something staff can fix when it occurs, but only Marcus would know the
long-term problem/solution.


#73 of 74 by mdw on Mon Mar 19 05:40:20 2001:

Could be a denial-of-service attack, I suppose.  The queue does
serialize actually opening a pty, so if several requests come in "at
once", the extra people could end up in the queue even though there are
apparently empty slots.


#74 of 74 by carson on Tue Mar 20 15:18:20 2001:

(net connections have been choppy and stuttered over the past few hours.
dunno if it's just Grex or if it's actually this end of the net.)
