50 slipped in.


#53 of 219 by gelinas on Thu Dec 30 03:14:42 2004:

The directory /usr/ucb does not exist.  It's now /usr/bin/tset .

Telnet does not authenticate nor encrypt the session.  So yes, you should
be worried about it; worried enough to switch to ssh. :)  

And change your password the first time you use ssh.


#54 of 219 by gelinas on Thu Dec 30 03:17:57 2004:

No, we aren't going to do anything with /usr/ucb.  It's not really possible
to figure out which programs were in that directory.  Better to get used to
not having it.

FWIW, I have /suidbin, /usr/local/sbin, /usr/local/bin, /bin and /usr/bin
on my path.


#55 of 219 by albaugh on Thu Dec 30 04:19:39 2004:

I edited .profile to use bin and the message went away.


#56 of 219 by keesan on Thu Dec 30 05:41:38 2004:

Rather than everyone having to edit .profile, .cshrc, etc., can a syumlink
be made from /usr/ucb to /usr/bin that works for everyone?  When I first set
up my grex account the newuser program set up something that involved tset
to set my terminal.  Many users will have no idea how to alter .profile.

#58 of 219 by blaise on Thu Dec 30 14:39:11 2004:

There's also the consideration that not everything that was in /usr/ucb
is necessarily now in a single directory.  I could easily see some
things that were in /usr/ucb on SunOS being in /usr/local/bin on OpenBSD.


#59 of 219 by gull on Thu Dec 30 16:08:38 2004:

Re resp:41: Are you running a 2.6 kernel, by any chance?  If so, try
this as root:

sysctl -w net.ipv4.tcp_default_win_scale=0

This turns off TCP window scaling.  It's on by default in 2.6.8 and
later, and some routers and operating systems don't handle it properly.
OpenBSD is one that's be identified by the Linux kernel developers as
problematic.  (The reaction by OpenBSD developers, judging from the list
posts I've seen, seems to be "Linux 2.6 is unstable and you shouldn't be
running it."  So don't hold your breath waiting for a fix.)

If adjusting that sysctl solves your problem, add this to
/etc/sysctl.conf or the equivalent in your distribution:
net.ipv4.tcp_default_win_scale=0

#60 of 219 by keesan on Thu Dec 30 16:49:16 2004:

I have ucb in two places:  .login  path includes /usr/ucb and .cshrc has an
alias for tset that includes the path /usr/ucb/tset.  Would it work to just
delete the /usr/ucb from both files (if .login is run before .cshrc then the
path should include /usr/bin already).

#62 of 219 by keesan on Thu Dec 30 17:20:55 2004:

I don't want to run tset in either place but that seems to be how newuser set
things up.  So I guess the scripts should substitute /usr/bin for /usr/ucb
in .cshrc and simply delete /usr/ucb in .login.

(#54 is the answer to #50's question, which was repeated in #56.  It's nice
to see that the subsequent responses echoed #54. :)


#66 of 219 by blaise on Thu Dec 30 22:04:03 2004:

(Er, #54 is an answer to #51, not #50.  #56 was a repeat of #51, so the
rest of your response stands.)

Thanks, Jim!


#69 of 219 by janc on Fri Dec 31 00:44:20 2004:

I ran a script that updated .login and .profile files, but only if they
were pretty close to the original distributed versions.  People who have
modified theirs much will have to fix them themselves.

There are two changes that need to be made to tset commands.  First the
path has changed from /usr/ucb/bin to /usr/bin.  Second, if you are
using the following syntax

    tset -m something  -m something  $TERM

It should be changed to

    tset -m something  -m something

That is, delete the '$TERM' thing.

I did this to nearly everyone's .login and .profile files, but my script
was conservative about not modifying things that had already been
modified.

I want to avoid as much as possible putting in symlinks for things like
this.  They would have to be there forever, they'd have to be recreated
everytime the system is upgraded.  I'd rather have the few people who
the script missed fix things once instead doing it over and over again
for the rest of my life.

It is useless and harmless to have /usr/ucb in your path.  I also don't
recommend putting /suidbin in your path.  Since that is non-standard, we
always have symlinks to anything you need there.


#70 of 219 by mfp on Fri Dec 31 00:53:48 2004:

Thanks, Jan!


#71 of 219 by twenex on Fri Dec 31 03:09:04 2004:

Re: #60. That worked a treat, thanks very much.

Hmm. If Linux 2.6 is "unstable", maybe I should try installing OpenBSD and
seeing what "stability" is like (I presume at least one recent version of
their system rates "stable" in their eyes). Personally, I think if WindowsXP
were so "unstable" as to require a one-line change in one config file to work
with an obscure OS's obscure network communication program, Open Source UNIX
wouldn't stand a chance in hell.


#72 of 219 by gelinas on Fri Dec 31 03:12:48 2004:

I don't understand that last sentence, twenex.  What does a simple config
change have to do with stability?


#73 of 219 by twenex on Fri Dec 31 03:24:28 2004:

I don't know, but the OpenBSD folks seem to think it has something to do with
it; see above.


#74 of 219 by gelinas on Fri Dec 31 03:29:19 2004:

Uhh, no.  The OpenBSD folks think Linux kernel 2.6 is unstable, therefore,
they are not going to put any effort into making OpenBSD work with it.
The change in config to make Linux work with OpenBSD doesn't affect linux's
stability one or another.


#75 of 219 by twenex on Fri Dec 31 03:33:31 2004:

Ah; I see. For a minute I thought *they* thought the two were connected.
Anyway, the point still stands that stability (or the lack of it) is in the
eye of the beholder. This Gentoo box is running gentoo-dev-sources, the
development version of the tweaked Gentoo kernel, without problems so far
after four weeks of use (touch wood).

Grex panicked.  So I cycled the power.


#78 of 219 by mfp on Sat Jan 1 06:27:26 2005:

THANKS<J OE!


#79 of 219 by twenex on Sat Jan 1 16:55:08 2005:

What was the cause of the panic?

(And they say Linux 2.6 is unstable. Apart from panics that result from
incorrectly specified boot parameters or an incorrectly built new kernel,
I've not seen one in years.


#80 of 219 by gelinas on Sun Jan 2 04:04:34 2005:

I don't know.


#81 of 219 by nharmon on Sun Jan 2 13:42:25 2005:

Please realize that Grex is using OpenBSD. OpenBSD is not intended to be
highly stable, although it tends to be. Nowhere in OpenBSD's stated goals will
you find the word "stable" :). OpenBSD emphasizes "portability,
standardization, correctness, proactive security and integrated cryptography"
(openbsd.org).


#82 of 219 by twenex on Sun Jan 2 14:07:51 2005:

That's as may be, however I find it rather laughable that the OpenBSD people,
(many if not all of whom, to be fair, have bad reputations in the personality
department) whinge about the instability of Linux 2.6 when that just happened
to their favourite system! (In fact the attitude of many BSD people in general
towards all things Linux seems stinky and hypocritical: "You use the GPL! You 
can't keep your source code secret even if you want to, neh neh neh neh neh! 
(Just don't mention that we use GCC too, ok?)"!) Rather like an article I saw
on Linux Today a few months back, where the author was saying that he liked
Macs, but didn't much like Mac-lovers. Maybe the Apple and BSD cultures are
compatible.

Have I ever mentioned that hypocrisy annoys me?


#83 of 219 by twenex on Sun Jan 2 14:15:18 2005:

"Correctness" to me would imply "stability", among other things. Why write
neat code if it borks?


#84 of 219 by naftee on Sun Jan 2 19:37:36 2005:

Write us some beat code that norks, twenex.


#85 of 219 by gelinas on Mon Jan 3 00:25:28 2005:

The file-table filled up, so no more files could be opened.  I had to cycle
the power to log on.


#86 of 219 by charcat on Mon Jan 3 02:52:34 2005:

Just now I couldn't use backtalk, I switched to dial up and got in but things
are hanging severly.


#87 of 219 by keesan on Mon Jan 3 04:06:14 2005:

I am dialed in and bbs (picospan) works fine.  Charcat I got your mails.


#88 of 219 by gelinas on Mon Jan 3 04:52:39 2005:

We have turned off the delivery of mail while we move the spool files out of
/var and onto a different partition.

You will see a variety of error messages, because many things use /var for
temporary space, until we get this problem resolved.  For example, vi saves
files to /var/tmp/vi.recover to allow the recovery of changes made but not
yet committed should the something crash while a user is editting a file.  So
users of vi will see a message like

        Error: Recovery file: No space left on device
        Modifications not recoverable if the session fails

when they begin to edit a file.  For now, ignore the error reports and go on
with what you were doing.


#89 of 219 by gelinas on Mon Jan 3 05:38:48 2005:

STeve freed up some space in /var, so we've turned mail on again.  Some time
later today (i.e., after sunrise, 3 January 2005), we'll take grex down while
we move the mail spool files to a different partition.


#90 of 219 by kalbaugh on Mon Jan 3 15:24:50 2005:

What happened to all my files?!!!


#91 of 219 by albaugh on Mon Jan 3 15:48:58 2005:

My files have returned just as mysteriously as they disappeared, and my mail
has been restored too.  :-)


#92 of 219 by gull on Mon Jan 3 20:08:19 2005:

Re resp:82: I agree with you for the most part...however, a system
hitting its maximum open file limit falls more into the
'misconfiguration' category than the 'stability' category.  You have to
remember that very, very few systems these days have the number of users
logging on simultaneously that Grex does.  It's not surprising that the
default, shipping configuration of OpenBSD needs a little tweaking. 
Most OpenBSD systems are used as network firewalls or the like.


#93 of 219 by twenex on Mon Jan 3 20:09:44 2005:

Fair enough.


#94 of 219 by steve on Mon Jan 3 23:13:04 2005:

  User mail files now live in their own partition, meaning that we have
lots of space for them now.  We're at about 14% utilitzation at the moment.
There are still more things to do with mail but I think things are going
ok now.

Also removed about 24,000 entries in the mail spool that were some form
of mail bombing.


#95 of 219 by twenex on Mon Jan 3 23:29:23 2005:

Like, yay. Thanks!

#97 of 219 by janc on Tue Jan 4 02:44:53 2005:

I had allocated a disk partition for mail (/var/mail) but I had left it
commented out in /etc/fstab (because normally during development we don't want
to mount the production mail directory).  I forgot to uncomment it, so the
separate partition was never mounted and the mail, instead, all ended up on
the /var disk partition, which was never intended to be big enough to hold
it.  Oops.

Thanks to the staffers who figured this out and copied things into the
proper mail partition.

Grex shouldn't be hitting it's maximum open file limit.  When I built Grex's
kernel, I just took the default size and doubled it.  Obviously this didn't
do the job.  I need to review what limits exist and how they are configured
to fine tune this.  Ideally things should be set up so that no one user can
consume all the system's resources.


#98 of 219 by janc on Tue Jan 4 04:08:28 2005:

By the way, Grex's web pages (including backtalk) are now accessible with teh
"https" protocol.

So you can run backtalk at "https://www.grex.org/cgi-bin/backtalk"

We don't have a real certificate (those cost more money than Grex can
afford), so it's just a crappy self-issued certificate.  However, you should
be able to tell your browser to accept it and not have to worry about it.
Even with the crappy certificate you'll be improving the security of your
connection to Grex substantially.  (With the old "http" protocol you password
was sent over the net in the clear with each connection.)  I recommend this
for all users.


#99 of 219 by aruba on Tue Jan 4 16:40:11 2005:

I'll be sending out paper receipts to people who donated to Grex last year
and would like a receipt for tax purposes.  So if you'd like a receipt for
your donations, let me know.


#100 of 219 by tsty on Wed Jan 5 00:02:29 2005:

thank janc and the others who made this new system and made the transition
so smooth. stunning!   applause!! applause!!


#101 of 219 by jep on Wed Jan 5 03:30:08 2005:

re resp:98: I notice I get a constant stream of pop-ups:

   Security Information
   This page contains both secure and nonsecure
   items.

   Do you want to display the nonsecure items?

Is this because the Backtalk buttons are accessible only via "http"?

I'd really like a fix if possible.

Thanks!


#102 of 219 by janc on Wed Jan 5 04:18:13 2005:

Hmmm...interesting.  I haven't looked at the code, but yes, very likely the
buttons are being fetched from a plain http URL.  However, the buttons are
not in a directory where authentication is required either, so your password
is not being sent in the http requests for the buttons.  So why in the world
would we want to encrypt those requests?  There's nothing secret about
backtalk buttons.  Encrypting them just adds extra overhead on Grex and on
your browser.  So I can't think of any sensible reason to encrypt button
requests except to make your silly browser happy.  (By the way, what silly
browser is that anyway?)  I should probably do it to make silly browser's
happy.  Sigh.


#103 of 219 by mooncat on Wed Jan 5 15:39:29 2005:

It's happened to me a couple times, I'm using Internet Exploder... er, 
Explorer. ;) Not my fault, it's the only thing work offers and 
downloads are not allowed.


#104 of 219 by twenex on Wed Jan 5 15:43:48 2005:

I prefer the term "Exploiter", though the way things are going we might get
a bit less exploitation soon.


#105 of 219 by blaise on Wed Jan 5 17:13:56 2005:

Personally, I prefer "Insecure Explorer".


#106 of 219 by albaugh on Wed Jan 5 17:50:54 2005:

> the way things are going we might get a bit less exploitation soon

Something developing on the MS front?


#107 of 219 by twenex on Wed Jan 5 17:55:08 2005:

No, but Firefox is picking up momentum. A US university (for example) (was
it Princeton?) - just sent an email to all its staff and students urging them
to drop IE for Firefox, because IE is so insecure.


#108 of 219 by jep on Wed Jan 5 18:21:36 2005:

I was using IE from home.  Sorry to ask for a fix to such a stupid 
problem (and yes, it *is* a stupid problem).  Does Firefox handle it 
better?

I won't be using https as long as I have to keep clicking on pop-ups in 
order to use it.


#109 of 219 by twenex on Wed Jan 5 18:25:20 2005:

Firefox can block popups, but that might disable the secure login itself in
this case. The only other fix I can think of is to email the webmaster and
ask him politely to write better code!


#110 of 219 by blaise on Wed Jan 5 18:32:02 2005:

That's not a popup in the usual sense of the word; it's a browser dialog
window.  IIRC, Firefox does not complain about mixed secure and insecure
items on a page; if I am wrong then it has a "never complain about this"
checkbox on the dialog.


#111 of 219 by twenex on Wed Jan 5 18:33:49 2005:

Oh, those. duh. Jim's solution sounds like a winner, though.


#112 of 219 by tod on Wed Jan 5 18:50:18 2005:

ANy of you ever delete the certificate authority roots out of your browsers
and start from scratch?  


#113 of 219 by gull on Wed Jan 5 19:53:39 2005:

Nope.  Why, you don't trust Versign? ;)

#115 of 219 by other on Wed Jan 5 20:43:09 2005:

MSIE has pretty configurable security settings.  I'd try looking for
ones that might be applicable here. Depending on how much you rely on
your brain and how much on your browser for secure surfing (you're far
better off with the latter), you might just want to switch the
applicable setting off.


#116 of 219 by jep on Wed Jan 5 21:14:11 2005:

re resp:115: that possibility had not occurred to me.  I did this:

Tools > Internet Options > Security > Internet > Custom Level
Under "Miscellaneous" there is a setting "Display Mixed Content" which 
is set by default to "Prompt"
I set it to "Enable" and that removed the problem.

Thanks!


#117 of 219 by nharmon on Wed Jan 5 21:14:55 2005:

Re #114
Is a cert from a company really necessary? And the cheapest I've found from
a source I trust (which is either verisign, geotrust, or thawte) is $149/year
(thawte.com).

IMHO, Grex's own certs are plenty fine for what it uses them for.


#118 of 219 by gull on Wed Jan 5 21:24:51 2005:

I agree.  I told Firefox to accept Grex's certificate permanently, so I
wouldn't be nagged about it every time.  I don't see what benefit a
trust path to an entity that's trusted by default (which is what you're
paying for) would have, here.

#120 of 219 by petercon on Thu Jan 6 15:41:00 2005:

Some people may have more problems in their scripts now that we've 
moved away from a SysV UNIX to a BSD UNIX - the "usr/ucb" directory in 
a SunOS sytem is where BSD UNIX commands were put in Suns SysV OS.  
Something like the move from Korn shell scripts to bash.  Shell scripts 
using Sun's SysV commands may not work the same in BSD (or be missing 
entirely) so be aware.  

Also, there are more differences in the directory structure and the 
whole environment and deamon setup that may affect scripts written in a 
SysV system.  Better test your scripts before trusting them.

What's going on eith Mozilla/Netscape? The article doesn't mention Netscape
as an alternative, though I've gotten the sense it is now related in some
fashion to Mozilla. 


#129 of 219 by gull on Thu Jan 6 17:05:15 2005:

Mozilla and Firefox are based on the same rendering engine.  I'm not
sure about Netscape; I think it forked off a couple years ago, but I
could be wrong.


#130 of 219 by twenex on Thu Jan 6 17:10:16 2005:

Mozilla began as an open source fork of Netscape; Firefox began as a
webbrowsing alternative to Mozilla, which is an Internet user's kitchen sink.


#131 of 219 by rcurl on Thu Jan 6 17:15:35 2005:

The "About Netscape" under Netscape 7.1 says

"Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4) Gecko/20030624
Netscape/7.1"

and

"Copyright 2000-2003 Netscape Communications Corporation. Portions of this
code are copyrighted by Contributors to the Mozilla codebase under the
Mozilla Public License and Netscape Public License."

So, is Netscape 7.1 the same as Mozilla 5.0?


#132 of 219 by remmers on Thu Jan 6 19:24:33 2005:

Someone correct me if I'm wrong, but I think that the latest Netscape
and Mozilla use the same "rendering engine" (Gecko) -- meaning that
web pages will look the same in both browsers -- but differ in other
details such as the user interface (menus, toolbars, etc.).


#133 of 219 by juicy on Thu Jan 6 19:44:51 2005:

after Netscape 4, the entire codebase was thrown out, and they started from
scratch.  The project was handed to a semi-independent, non-profit (I think)
organisation, the Mozilla Foundation, and the source opened.  Mozilla was
released as a development version, starting w/ version .1 (or, before that,
Milestones counting up to I think 18); every so often, especially quality
Mozilla releases have been forked as official Netscape releases, starting with
NS 6.0.

At some point in the last several years, it was decided that instead of
offering the entire kitchen sink at once, users should be able to just get
the parts they want and build their own sink at home, so now there are the
Moz Firefox (browser), Thunderbird (e-mail), Sunbird (calendar), and Lightning
(calendar/address book synchro, I think) projects; you can also still get the
entire package at once.  You can read more about Mozilla at
http://www.mozilla.org/about/ ; there's probably a link to a page about the
history of the Mozilla project around there somewhere, although I don't see
it.

It seems to be case sensitive. Try http://www.omegahat.org/RCurl/
I suppose, eventually, everyone here will be a Package...

For users of "mail", here is something I discovered is different about the
mail program on nextgrex:

R [message list]                reply to message sender(s).
r [message list]                reply to message sender(s) and all recipients.

Use of just lower case "r" annoyingly adds you (the recipient) to the reply
distribution.  Use capital R instead.


#139 of 219 by naftee on Thu Jan 13 05:12:54 2005:

re 137 Yeah, whoops.  Silly me for thinking all URLs were not case-sensitive.


#140 of 219 by juicy on Thu Jan 13 06:02:53 2005:

nope, just the domain.


#141 of 219 by gelinas on Fri Jan 21 23:56:54 2005:

Grex will be unavailable from 12:00 to approximately 15:00 tomorrow, 
22 January 2005, while it is moved from the Pumpkin to provide.net.

The old machine will move back to its old IP address, but logins (and mail)
will be disabled; it is moving back to provide DNS service for our domain
until our domain registration is updated.

#143 of 219 by keesan on Sat Jan 22 04:39:14 2005:

Does this mean grex will be available via the website using the old machine?


#144 of 219 by gelinas on Sat Jan 22 05:04:52 2005:

I don't quite see how you reached that conclusion, but no: www.cyberspace is
an alias for grex.cyberspace, and so will move along with grex.  I mentioned
logins because _some_people will probably try to connect by IP address
instead of domain name.


#145 of 219 by keesan on Sat Jan 22 05:18:02 2005:

Why is it not possible to hook up the old grex to the same ISP connection and
DSL modem to check if the problem is in the computer or in something else
(such as the DSL modem or the connection to the ISP)?  Would this interfere
with using it as a DNS server?  And why do we need a DNS server if grex is
not working?


#146 of 219 by gelinas on Sat Jan 22 06:20:55 2005:

oldGrex _is_ on the same connection as the current grex.  I log into it
regularly.  However, since I'm the only user, there is not much going on.
There are other machines on the network as well, which other staff members
use regularly.  They have mentioned seeing similar behaviour there.

We need a DNS server so that people can find our machine by its name.  This
is one of the functions of the main machine.  However, DNS "bootstraps" from
an IP address.  Right now, that IP address is 216.93.104.34.  Until I can get
the new IP address registered, and so get the 'bootstrap' fixed, we have to
keep a DNS server running on the old address.


#147 of 219 by keesan on Sat Jan 22 11:54:50 2005:

Similar or ientical behavior?  Could we have two different problems at once?
The old problem was 2 minute freezes every few minutes.  This is 10 sec
freezes every couple seconds.  The old problem occurred during telnet, not
dialup.  What is the motehrboard maker and model?  Please email
keesan@freeshell.org


#148 of 219 by gelinas on Sat Jan 22 21:11:35 2005:

ASUS, and I looked at the capacitors; they are fine.

Grex is now in the new location.

It will take a bit longer to get the dial-ins re-directed.


#149 of 219 by naftee on Sun Jan 23 02:17:26 2005:

gelinas, why don't you refer ms. keesan to a text on networking, and save
yourself some time and energy?  I hate to see you stressing out.


#150 of 219 by gull on Sun Jan 23 22:36:34 2005:

Everything is nice and fast now.  Good work.

I was a little confused yesterday when I connected via dialin and got
something like this after logging in:

This is _NOT_ Grex.  Use the domain name, not the IP address.

Dialin Users
NO CARRIER


#151 of 219 by keesan on Sun Jan 23 23:23:34 2005:

Ssh connection is nearly instant.  Telnet not working, but it worked this
morning, very slowly.


#152 of 219 by naftee on Mon Jan 24 02:16:49 2005:

Just re-booted.


#153 of 219 by keesan on Mon Jan 24 04:10:15 2005:

Telnet and pine are working again but I have not received any mail for a few
hours except something from grex.  I would have expected 10 spams in this
period.


#154 of 219 by gelinas on Tue Jan 25 18:44:56 2005:

Grex panicked and did not reboot itself Monday evening.  


#155 of 219 by gelinas on Tue Jan 25 18:49:00 2005:

I think I fixed the terminal server to connect to the new machine last night,
so dial-in should be working again.

I also think I fixed the web proxy to accept requests from the new machine.


#156 of 219 by scholar on Tue Jan 25 19:30:32 2005:

Thanks, Joe!


#157 of 219 by keesan on Wed Jan 26 03:15:25 2005:

What does 'grex panicked' mean in more technical terms?  Is this some odd
hardware problem or a response to something done to the software?  


#158 of 219 by janc on Wed Jan 26 03:43:53 2005:

Software.


#159 of 219 by keesan on Wed Jan 26 03:46:23 2005:

I get a kernel panic when I tell it there is more memory than actual, or to
put root on some nonexistent device.  Did you do something equally clever?


#160 of 219 by janc on Wed Jan 26 03:58:20 2005:

I installed a slightly newer version of backtalk and fronttalk.  Backtalk has
suffered quite a few internal reorganizations aimed it making various things
I want to do in the future easier to do.  There's always a risk of introducing
new bugs when I do this, but that's life.  The major bug fix in Backtalk is
to the date parsing.  "read since" type commands should work much better.

Fronttalk has had more noticable changes.  First, it now has command line
editting (via a package known to Unix geeks as "readline") similar to what
you see in tcsh and other modern shells.  That means you can use the arrow
key to move back into the command you are typing and edit it, or use the up
arrow key to move back in the command history and reissue previous commands.

The "read since" command was working badly.  It should now work much better.
The date syntax understood by Backtalk isn't exactly the same as Picospan or
Yapp - it actually accepts a much wider range of date syntaxes.  Doing
"help date" in Fronttalk will tell you more than any sane person wants to
know about Fronttalk date formats.  Backtalk now implements the Picospan
"date" and "cdate" commands, but they are pretty useless, so don't worry
about it.

Control-Z generally should work better now in Fronttalk - things should
work smoothly when you suspend/restart the program.  Actually, part of this
was a BSD portability fix in Gate, so it may fix sometime problems for
Picospan users too.

I would encourage regular users of "bbs" (Picospan) to try out Fronttalk.
You run Fronttalk with the "ft" command.  The plan is that Fronttalk will
eventually replace Picospan on Grex.  Trying it out now to make sure it
behaves well for you would be wise.


#161 of 219 by janc on Wed Jan 26 03:59:57 2005:

Re 159:  No, this is probably an OpenBSD bug.  There is a theory that it is
due to using soft updates, a feature that may not be fully mature in OpenBSD
version 3.5.  We don't actually know what caused the last crash though. 
Things are being tried.


#162 of 219 by twenex on Wed Jan 26 12:07:23 2005:

A kernel panic is the UNIX version of a Windows "Blue Screen of Death" -
except that the last time it happened every day was probably in 1971 or so.
For the record, Windows isn't the worst - IBM's ill-fated TimeSharing System,
TSS, took over 10 minutes to boot up, but mean time to failure was less than
that. D'Oh!


#163 of 219 by keesan on Wed Jan 26 13:55:10 2005:

I am trying out fronttalk now and when I hit the left arrow I get [D and a
beep.  Am I supposed to be able to back up?  The up arrow give me [A and a
beep.  I have an 84-key keyboard and am using linux.  Down arrow [B.  Right
arrow [C.  Backspace works as expected.  


#164 of 219 by mooncat on Wed Jan 26 14:57:35 2005:

Not sure if this is just me or not, but instead of seeing apostrophes 
in responses I keep seeing:  &apos;

In case it matters, I'm using Internet Explorer.


#165 of 219 by slynne on Wed Jan 26 15:12:48 2005:

I am seeing the same thing. I am also using backtalk with IE browser. 


#166 of 219 by slynne on Wed Jan 26 15:13:21 2005:

Oops wrong item. 


#167 of 219 by mooncat on Wed Jan 26 16:34:25 2005:

(Yeah, I noticed that too. ;) )


#168 of 219 by remmers on Wed Jan 26 16:44:58 2005:

Re #164, #165: Can you point to some specific items where the &apos;
problem occurs?


#169 of 219 by janc on Wed Jan 26 16:48:33 2005:

resp:163 (keesan):

  I would guess that your termcaps are set wrong.  Do your arrow keys work
  in anything else?

resp:164: (mooncat)

  IE doesn't do &apos; ?  Yuck.  I guess I should take that out.


#170 of 219 by janc on Wed Jan 26 16:50:11 2005:

Backtalk changes lots of symbols into responses into other things, like <
becomes &lt; and & becomes &amp;.  The browsers change them back.  The new
backtalk also changes ' into &apos;.  Evidently IE does not change it back.


#171 of 219 by janc on Wed Jan 26 17:14:22 2005:

OK, I've fixed Backtalk to turn quotes into &#39; which IE apparantly does
understand.


#172 of 219 by remmers on Wed Jan 26 17:18:22 2005:

Right - I suspected it was IE lameness.  Seems to me I had a problem once
with IE not recognizing '&apos;' despite every other modern browser doing
so.


#173 of 219 by janc on Wed Jan 26 17:19:36 2005:

To state the obvious, IE is not a modern browser.


#174 of 219 by remmers on Wed Jan 26 17:20:29 2005:

Yeah - scratch the word 'other' from my response #172.


#175 of 219 by keesan on Wed Jan 26 18:05:49 2005:

My left arrow acts the same on my 101-key keyboard - BOTH left arrows.
Terminal type is vt100.  I am telnetted from linux.  Perhaps I should choose
linux instead.


#176 of 219 by tod on Wed Jan 26 18:15:28 2005:

Have you tried vt52 or vt102 or vt220?


#177 of 219 by jep on Wed Jan 26 18:33:19 2005:

The problem with the &apos; characters is fixed.  Thanks, Jan!  
Unfortunately I am limited to IE at work.  As IE was one of the first 
browsers with the capability to display XML, I am surprised it doesn't 
handle the &apos; character entity.  I wonder why it doesn't?


#178 of 219 by mooncat on Wed Jan 26 19:33:11 2005:

All better now! Thanks!!


#179 of 219 by keesan on Wed Jan 26 19:49:45 2005:

I think VT320 is the same as VT200 or VT102 with more features.  


#180 of 219 by naftee on Wed Jan 26 19:53:49 2005:

re 173 How so ?


#181 of 219 by janc on Wed Jan 26 20:39:50 2005:

Sindi:  In the old days "vt100" refered to an actual terminal you could put
on your desk rather than a protocol.  People would use these extremely dumb
computers to connect to servers, and what codes were sent to the server when
they hit and arrow key were different depending on what make and model of
terminal you had.  A DEC VT100 would send different codes than an IBM 3101
(I miss my trusty IBM 3101 - that thing could really hold a desk down).

Whatever software you use to connect to Grex (or under Unix, the terminal
window it runs in) pretends to be one or another of these fine old historical
monsters.  Usually either VT100 if the programmers were lazy, or a much
extended version of VT100 called ANSI if they were more ambitious.  So the
codes sent depend on the software on your computer, not on the actual keyboard
you are using.  You mention Linux.  Are you running xwindows?  If so, you
probably want 'xterm'.  If not, I guess probably 'ansi'.

However, I could be wrong about this.  Maybe your TERM setting is fine.  If
the arrow keys work for you in lynx, it is probably right.

Fronttalk doesn't actually do any of this logic itself.  It uses a library
module called "readline" that is also used by many of the shells on Grex, like
tcsh.  It would be very odd if your arrow keys worked in any of those, but
not in Fronttalk.

One thing just barely worth checking:  Type "display readline" in fronttalk.
It should say that readline is turned on and mention "Gnu" (since we are using
the Gnu readline library).


#182 of 219 by remmers on Thu Jan 27 01:53:52 2005:

Re #177:  Microsoft decided to stop all development on IE a few years ago.
I guess they figured IE was so well entrenched as the leading browser that
they could rest on their laurels.  Unfortunately that left their support
for XML and CSS in an incomplete state.  Meanwhile, web standards have
been evolving and other browsers (Mozilla, Firefox, Opera) have been
keeping up, but not IE.  Web designers are not pleased with IE these
days.


#183 of 219 by keesan on Thu Jan 27 13:37:33 2005:

I have typed 'tset ansi' (which gave me the usual login messages for some
reason) and then ft and will now test arrow keys.  I still get [D.  My
terminal setting on my linux computer is 'linux'.  Then I choose vt100 at grex
(I also tried linux here with no better results).  Where do I type display
readline, at line start in fronttalk?
display readline
I just typed it and got nothing back.  I am not using X.  
Lynx and links work (offline anyway) as expected here.


#184 of 219 by naftee on Thu Jan 27 20:18:56 2005:

re 182 Oh.  Is this related to the fact that Microsoft stopped working on
their own virtual machine for Internet Explorer, and told peole to use Sun's
instead?  This being for java.

Re resp:182: That's what happens when one company dominates the market 
and manages to push everyone else out.  Innovation comes to a halt. 
 
Re resp:184: Not exactly.  They lost a lawsuit with Sun, and aren't 
allowed to distribute their VM anymore.  I don't understand the 
details, but I think it had to do with them creating an incompatible 
version of Java by "embracing and extending" Sun's API.

#189 of 219 by gelinas on Sun Jan 30 06:43:23 2005:

OK.  This time, I really think I've fixed the terminal server.  I had to
reconfigure each port, individually.

Dial-in *should* be working again.  Finally.


#190 of 219 by mary on Sun Jan 30 13:10:12 2005:

Thanks, Joe.  Must be frustrating.


#191 of 219 by keesan on Sun Jan 30 13:56:18 2005:

I tried to dial in ten minutes ago and got three lines of garbage
followed by a hangup,  so I telnetted but the load average was 89 with
ggg running 90 or more copies of the same process for the past 4 hours
(minutes?) or so. It was too slow to figure out if this is a dial-in
vandal.


#192 of 219 by janc on Mon Jan 31 19:47:42 2005:

Installed a new version of fronttalk with various bug fixes.

I don't know what's going on with keesan's arrow keys.  It does say 
"Fronttalk" when it starts up, right?  Should be version 0.9.0 now.


#193 of 219 by naftee on Mon Jan 31 21:21:15 2005:

Any chance you can install the current version on m-net ?


#194 of 219 by gelinas on Wed Feb 2 01:47:24 2005:

Grex will be getting a new telephone number for dial-in access.  We aren't
able to move the old number to the new location.


#195 of 219 by mary on Wed Feb 2 02:34:08 2005:

Bummer.


#196 of 219 by keesan on Wed Feb 2 04:04:30 2005:

One number for two lines?


#197 of 219 by janc on Wed Feb 2 05:43:13 2005:

I have no root access on M-Net, so I can't install anything there.

I did however install version 0.9.1 here.  Fixes a few more bugs.  Adds
a few more fairly obscure features.  Read Garager if you want gory details.


#198 of 219 by naftee on Wed Feb 2 18:36:03 2005:

O,ok. thanks;.!


#199 of 219 by gelinas on Wed Feb 2 22:07:13 2005:

Two lines, two numbers, in a hunt group.  So folks really only need to know
one number, just like now.


#200 of 219 by keesan on Thu Feb 3 04:45:03 2005:

A dial-in user asks what the new numbers will be.


#201 of 219 by gelinas on Thu Feb 3 04:49:46 2005:

As soon as I know, I'll spread the word.


#202 of 219 by gelinas on Thu Feb 3 20:24:21 2005:

The new telephone numbers are 734-484-0512 and 734-484-0513.  The numbers
will not answer until the modems are moved, of course.  I expect to move the
modems tomorrow.

The old number will forward to the new number for ninety days.  

Sic transit gloria mundi.

One of the modems is now connected to grex.  I think it is connected to

#210 of 219 by gelinas on Mon Feb 7 20:36:54 2005:

I installed a second modem and replaced the first modem.  I _think_ the
problem with first modem was caused by heat: the modem was lying flat on top
of the machine case.  I moved it to the top of the cabinet and set it on
edge, as had been done in the Pumpkin.

I also moved Grex's powerplug to the powerstrip the modems are plugged in to,
to lessen our 'footprint'.  It may also alleviate grounding problems between
the modems and Grex.
