Looks like the fairwitnesses of those conferences have established userlists,
and y'all aren't on them.  (FWIW, neither am I.)

The limiting files, /bbs/{confname}/ulist, are world-readable.

Nobody is forcing you to come here.  Feel free to leve at anytime, and
never darken our doorstep again.

Feel free to leve at anytime,

especially Now and Forever.


#290 of 405 by pfv on Sat May 15 12:10:53 2004:

Umm... How many times do you now have to type your password, to satisfy
login? It's been fighting for two days and only seems to let me on with
telnet after it prints a "badlogin.html" message, (ssh fails long before
that).


#291 of 405 by scott on Sat May 15 12:20:02 2004:

The backtalk2 conf userlist is people who were staff back then, for the
original Backtalk testing.  Guess that ought to be fixed.

Re: #290. I regret to announce I can't corroborate this problem, except once,
when it *might* have been my typying that caused the problem anyway.


#294 of 405 by gelinas on Sat May 15 14:10:43 2004:

pfv, when that happens to me, it usually means that one (or more) of the keys
on my keyboard is sticking.


#295 of 405 by gull on Sun May 16 01:30:04 2004:

I've seen it happen when something was wrong with Grex that was causing
Backtalk's login routine to time out.


#296 of 405 by tsty on Sun May 16 01:54:08 2004:

third time through,.... damn disconnects!


#297 of 405 by drew on Mon May 17 20:28:02 2004:

Why does SSH keep dropping my connection? Once in a while is tolerable but
this is getting out of hand!


#298 of 405 by krj on Mon May 17 21:37:42 2004:

Telnet connections are pausing frequently enough that Grex is only
marginally useful.  The party log should show lots of complaints.


#299 of 405 by mcnally on Mon May 17 21:50:03 2004:

  It is a serious problem, and probably deserves to be top priority as
  soon as a staff person has time.


#300 of 405 by gelinas on Mon May 17 22:31:18 2004:

(I think we are waiting the delivery of a DSL modem.)


#301 of 405 by keesan on Tue May 18 00:30:22 2004:

I was unable to telnet in.  I have been telnetting because the dialin
connection keeps freezing up for 1-2 minutes, and it is quicker to untelnet
and telnet back than to dial again.  


#302 of 405 by albaugh on Tue May 18 03:40:25 2004:

If the problem is definitely the DSL modem, and it's just a matter of waiting
until the replacement arrives, then I will hold my tongue and try to be
patient...


#303 of 405 by tsty on Tue May 18 04:13:28 2004:

glad the problem has been identified and conrrectins are on the way.


#304 of 405 by charcat on Tue May 18 04:39:41 2004:

Thanks for the information gelinas, I was wondering also.

Net connection down. But shouldn't the idle zapper have zapped some of
those idlers? 


#306 of 405 by kip on Wed May 19 18:19:43 2004:

Haven't worked with the idle zapper yet, not sure, would think so.

DSL back up.  I'll be trying out the replacement DSL modem after work today


#307 of 405 by twenex on Wed May 19 19:19:01 2004:

Patience? What patience? ;-P


#308 of 405 by kip on Wed May 19 23:26:45 2004:

On the DSL news front, I tried out the new modem, but it remained in IDSL
mode and wouldn't connect to our SDSL connection.  I'm taking it home and will
reread the manual to see what I missed.

Also, our old DSL modem managed to lock up starting about 1:00am EDT today,
I didn't get a chance to run down to the Pumpkin until about 2:00pm to kick
it.  Amusingly, the stats for the old modem from 2:15pm to 7:00pm, when I
disconnected it to try the new modem, were perfect with no errors what so ever.

Did anyone happen to notice if they had lag between 2:15pm and 7:00pm today?
I'm still talking to our ISP in case it turns out to be the line.  :)


#309 of 405 by mcnally on Thu May 20 00:28:35 2004:

  If the new DSL modem isn't linking to the provider's DSLAM it's probably
  because you need information about what settings to use;  hopefully the
  provider can provide them if they haven't already done so.

  I'm not sure what information you have about the connection already but
  DSL comes in a pretty wide range of flavors, including different line
  codings, different protocols, different authentication specifications,
  etc..  It's not realistic to just plug in a DSL modem and expect it to
  work without knowing more about your provider's setup.  

  Most probably you already knew all that, but I mention it just in case
  you didn't.  DSL is unfortunately not as "plug and play" as many other
  networking technologies.


#310 of 405 by achu on Thu May 20 00:32:09 2004:

in ancient china, communications took a different route.

everyone knows about the chinese pea shooters that young boys like to wield.

but where did this enwielding custom come from?

it came from a sort of training.  in ancient days, the land of china was
covered by vast networks of bamboo connecting post offices in cities towns
and villages to other post offices in other ctvs.  messages would be
transported pneumatically by blowing strongly into one endexpress mail was
also sucked.  the people learned how to do this by first practicing with pea
shooters.

#314 of 405 by mcnally on Thu May 20 18:05:13 2004:

  Admittedly, even after most of a year working for a DSL provider
  I haven't mastered a good deal of the lingo (the telco side being
  perhaps even worse than the computer side for having its own 
  vocabulary) but at least as I have usually heard them used, "ADSL"
  vs "SDSL" shouldn't matter.  The "A" and the "S" stand for 
  "asymmetric" and "symmetric" and refer basically to the upload and
  download speeds.  Those aren't generally things that need to be set
  up in the customer's modem, they're more usually limited by the 
  provider at the DSLAM.

  I won't know the specifics for your DSL provider but it's possible
  I can still provide advice on the DSL issue.  Don't hesitate to ask
  if you need assistance..


#315 of 405 by twenex on Thu May 20 18:08:58 2004:

Re: #314. Yeah; people who complain about computers being hard to use wuold
be totally lost in the telephone world if what i've seen of it is anything
to go by. As a self-confessed geek, the stories in Levy's HACKERS about theMIT
Hackers who engaged in phreaking struck me as really nerdy. Yes, I can smell
the irony right here. It's burning my butt.


#316 of 405 by mcnally on Thu May 20 18:40:19 2004:

  re #314:  My mistake -- I thought in the other item you'd said "ADSL", 
  not "IDSL"..


#317 of 405 by twenex on Thu May 20 18:42:48 2004:

So, what's "IDSL"?


#318 of 405 by scott on Thu May 20 20:49:15 2004:

"Intermittent Digital Subscriber Line".  Strangely unpopular, though.


#319 of 405 by twenex on Thu May 20 20:51:30 2004:

I see. Thanks. Maybe the "intermittent" has to do with unpopularity. maybe
peple think it's Redmond Quality h/w.


#320 of 405 by kip on Thu May 20 21:38:50 2004:

Sorry, the day job has been pretty full today and I still have a class to
teach tonight, so I haven't made much headway.

IDSL stands for ISDN Digital Subscriber Line and is usually used where ADSL
and SDSL can't reach due to the excessive distances from the Central Office.

The issue appears to be that I'll have to replace the firmware in the DSL
modem to deal with SDSL or RFC1483, as it is currently set to deal with
IDSL/Frame Relay/RFC1490.

Anyway, I'll be looking into tonight after class.


#321 of 405 by kip on Thu May 20 21:41:29 2004:

Plus the silly manufacturer really writes their stuff like you'll always have
a Windows PC laying around to install all sorts of nasty software on it just
to do things like TFTP.  We've got a perfectly good OpenBSD box to do that
with instead.  :)

Re resp:315: I recently had to deal with an SBC employee who needed some
specific information about our phone system at work.  He kept using
telco lingo that I didn't understand, and when I'd say "I don't know
what that is" he'd just repeat the same thing over again.  He was
totally incapable of communicating with anyone who wasn't familiar with
the jargon.

We've been trying to switch our phone system from KMC to SBC, but for
some reason they want a bunch of highly technical information that we
don't know and have never had to provide before.

#335 of 405 by keesan on Mon May 24 22:22:02 2004:

Time to change the motd?


#336 of 405 by gelinas on Tue May 25 00:56:03 2004:

We usually leave notices up about a week, so no, I don't think it's time to
change the motd.


#337 of 405 by davel on Tue May 25 21:18:34 2004:

That's good, since some people don't log in even weekly.  But an item that
says something like

> Grex was off the DSL at 7:00pm EDT for a few minutes to try out a different
> DSL modem.  The test was unsuccessful.  Staff is looking into it further. 

without specifying a date then becomes very confusing.  Was this before or
after the May 19 loss which was also in the motd?

I admit that I'd rather have staff working on the problem than writing motd
notices, though.


#338 of 405 by keesan on Wed May 26 16:59:26 2004:

The motd is now one week old and the Wednesday referred to is last Wednesday.
I have not had any problems for the past few days on grex.


#339 of 405 by albaugh on Wed May 26 21:18:51 2004:

Yep, if motd authors could remember, it wouldn't be a bad idea to prefix each
item with the date the item was added, e.g.:

5/19: Grex was off the DSL at 7:00pm EDT for a few minutes...


#340 of 405 by wlevak on Mon May 31 04:35:00 2004:

IT appears to be down again


#341 of 405 by wlevak on Mon May 31 05:26:18 2004:

It's working normally now.  Did someone fix it, or did it do it by itself?


#342 of 405 by keesan on Mon May 31 16:35:01 2004:

I am getting frozen connections again, when telnetting from grex to elsewhere.


#343 of 405 by mcnally on Tue Jun 1 07:38:58 2004:

#344 of 405 by twenex on Tue Jun 1 15:07:23 2004:

An update on progress (or lack thereof) with the replacement dsl modem might
be nice. It's starting to get worse again.


#345 of 405 by rcurl on Tue Jun 1 17:40:24 2004:

Just got dumped from my telnet connection. Viva dialins....


#346 of 405 by gull on Tue Jun 1 19:42:45 2004:

Seems to have been down since this morning...at least, the two times I've
tried to SSH in, it's timed out.

How's the new modem coming?

It's back!!!


#350 of 405 by richard on Wed Jun 2 17:35:37 2004:

Last night for a period of time grex's url's were pointed elsewhere.
www.cyberspace.org brought up a search engine.  www.grex.org brought up a
different search engine.  In the past when grex went off the 'net, you
would get a "page not found" or some other error.  If somebody at grex's
isp changed its urls to pointers to point elsewhere, does that indicate
more than just a hardware problem?  


#351 of 405 by aruba on Wed Jun 2 19:03:50 2004:

That sounds very weird, Richard.  Are you sure your browser isn't infected
with adware?  Sometimes adware will redirect your browserto where it wants
to go.  What browser are you using, and what search engine did you get?


#352 of 405 by twenex on Wed Jun 2 19:08:04 2004:

That sounds like the most plausible explanation to me, too.


#353 of 405 by scott on Wed Jun 2 20:54:28 2004:

That or a localized DNS problem.  A couple weeks ago I absolutely could not
get a connection to a well-established website for a couple days.  Couldn't
even send mail; it would bounce.


#354 of 405 by richard on Thu Jun 3 03:22:35 2004:

well I did have some evilware that snuck in and installed itself on my hard
drive. But thats a side effect of doing a lot of websurfing.  A lot of those
pop up ads on ad driven sites come loaded with hidden downloads.  But I've
never had that particular issue at other times when grex was off the web. 
Its an annoying bad habit of my computer that its supposed to notify me if
anything is being downloaded, but things still get by it and install
themselves anyway from time to time


#355 of 405 by aruba on Thu Jun 3 04:09:55 2004:

My roommate had the same thing happen to him recently.  He had to boot up in
safe mode and delete some files, before they had a chance to run. 
spyware.com was helpful.


#356 of 405 by bru on Thu Jun 3 14:53:29 2004:

My ISP is now checking mail, and they have blocked 4 mails perportedly from
Microsoft about critical security upgrades that they say have virus attached.
Is that normal?


#357 of 405 by gelinas on Thu Jun 3 15:12:51 2004:

Roughly speaking, yes, it is normal, bru.


#358 of 405 by gregb on Thu Jun 3 15:16:13 2004:

No it's not.  If there are security updates, you'll receive them via IE,
either through Auto Notification or by clicking Update Windows in the
Tools menu.


#359 of 405 by mcnally on Thu Jun 3 16:19:28 2004:

  Conflicting answers above can be explained as a confusion between:
  "yes, it's normal to block them", and "no, it's not normal to receive them."


#360 of 405 by tpryan on Thu Jun 3 16:30:26 2004:

        Normal to get them?  Well, I was getting them on a regular
basis, until Earthlink learned they used less resources to block 
the virus attached.
        Using Update Windows is the better method for finding about
security updates.

#362 of 405 by gelinas on Thu Jun 3 18:30:26 2004:

Right; Microsoft does not distribute its security updates by e-mail.
Several viruses DO distribute themselves by e-mail by masquerading as
Microsoft security updates.

So blocking them is normal, and receiving them is normal.  Even applying
them is also normal.  However, applying them is not desirable.

I've been getting denials of access by both ssh (login refused) and telnet

is up, and the DSL line is up.

WTF is going on here?


#366 of 405 by russ on Thu Jun 3 23:33:11 2004:

Grex is closing my ssh connections after barely a minute or two
of time on-line.  No messages given.

Re: 354
> But thats a side effect of doing a lot of websurfing.

Not really.  I surf all the time, and have no problem.  I just don't use
Internet Explorer.  I tend to prefer Mozilla 1.6, unless the website
requires a broken HTML and/or CSS parser, such as one would find in IE.


#370 of 405 by gull on Mon Jun 7 15:15:17 2004:

I like Firefox, which is really just Mozilla without all the non-browser
stuff.  I haven't run into a website in a long time that I had to resort
to IE for, except for Windows Update.


#371 of 405 by twenex on Mon Jun 7 15:29:23 2004:

Agreement.


#372 of 405 by gregb on Mon Jun 7 16:10:02 2004:

I'll second that agreement.


#373 of 405 by wlevak on Thu Jun 10 05:19:29 2004:

It's down again.


#374 of 405 by gull on Thu Jun 10 14:52:44 2004:

So the new modem didn't fix things?  Or was it never installed?


#375 of 405 by gregb on Thu Jun 10 15:41:17 2004:

It died on me while I was posting a reply.  Consequently, I lost the reply.


#376 of 405 by wlevak on Fri Jun 11 21:03:59 2004:

Down again.   "who" list a number of sessions that don't have normal ip's.
Should those be there?


#377 of 405 by wlevak on Fri Jun 11 21:24:37 2004:

I just did "finger" on all those strange ip's.  Except for newuser, they are
users whose sessions have been idle for many days.  Perhaps someone with
administrative authority should log them out?


#378 of 405 by davel on Fri Jun 11 22:03:16 2004:

Yes, it is down.  I also notice the long idle times - is the zapper dead?

#383 of 405 by mcnally on Wed Jun 16 17:37:08 2004:

A small amount of space has been freed up on /a but utilization is near 100%.
Staff, please help!


#384 of 405 by gelinas on Wed Jun 16 18:01:35 2004:

I freed up another five percent.  More later, when I have more time.


#385 of 405 by mcnally on Wed Jun 16 18:22:59 2004:

  Thank you.


#386 of 405 by gelinas on Wed Jun 16 19:29:09 2004:

And it looks like someone else freed up a bit more space.


#387 of 405 by pgreen on Wed Jun 16 20:57:24 2004:

You're welcome!


#388 of 405 by drew on Fri Jun 18 00:17:24 2004:

/a is at 100% again.


#389 of 405 by wlevak on Fri Jun 25 04:25:30 2004:

The last 3 times I dialed in I did not get a connection on the first try. 
The responding modem gave either a constant tone(not searching for the
matching protocol) or no tone at all.  It sounds like you have a defective
modem.

Lynx is very slow tonight.  It took 3 minutes just to get to this point to
enter this response.


#391 of 405 by wlevak on Sat Jul 17 05:59:29 2004:

It went back to "normal" at about 12:45.  Did somebody do something to the
system?


#392 of 405 by rcurl on Thu Jul 22 05:20:25 2004:

Looks like some vandal is at it again - 110 newresponse items, and items
'activated' but with no response. 




#393 of 405 by mary on Thu Jul 22 11:49:14 2004:

I think Tod went through and scribbled all of his responses.
He does this on a regular basis.  I've adopted a policy of
filtering him so I never see his comments to begin with.
Filtering is my way of dealing with twits.  I prefer it to
public whining. ;-)


#394 of 405 by rcurl on Thu Jul 22 13:02:00 2004:

I think it would be better to have a system-wide solution, rather than having
to do it person-by-person. 


#395 of 405 by gull on Thu Jul 22 13:57:37 2004:

I'd rather that staff work on something more vital, like NextGrex.  If
that project still exists, anyway.


#396 of 405 by rcurl on Thu Jul 22 15:09:49 2004:

LIttle things are being "worked on" all the time - add scribble-window
to the list. 


#397 of 405 by gelinas on Thu Jul 22 19:51:58 2004:

"scribble-window"?  What would it do?


#398 of 405 by gelinas on Thu Jul 22 22:39:22 2004:

(Never mind; I got the answer in a more current item.)


#399 of 405 by wlevak on Sat Aug 14 22:53:38 2004:

What happened?  I was not able to get on Friday night or Saturday morning.
The modem would answer and connect, and then disconnect.


#400 of 405 by wlevak on Thu Sep 9 22:51:54 2004:

GREX seems to be messed up again.   Very long time to get login prompt and
then Lynx doesn't find any outside links.


#401 of 405 by wlevak on Sun Sep 12 04:11:43 2004:

So why does it still take forever to get a login prompt?


#402 of 405 by tod on Sun Sep 12 22:41:58 2004:

DITTO!


#403 of 405 by wlevak on Mon Oct 4 03:19:46 2004:

The DSL line is obviously down again.


#404 of 405 by gelinas on Mon Oct 4 11:17:15 2004:

And was just power-cycled.


#405 of 405 by wlevak on Wed Oct 6 04:41:48 2004:

The system is very flakey tonight.  It took three tries to dial in.  The
connection was then dropped after a few minutes.  It took two more tries to
get on again.  The response time was also very erratic, sometimes responding
immediately, and then frequently taking 20-30 seconds.
