The /a partition was full, preventing users whose home directories are
located on it from responding in bbs, saving their mail, and doing anything
else requiring writing data to the disk.  I identified the major disk 
hogs and did some cleaning up, giving us a bit of breathing room.


#189 of 237 by i on Sun Aug 31 20:11:21 2003:

[Loud cheer for the Grexasaurus from the /a users]


#190 of 237 by rcurl on Sun Aug 31 22:58:37 2003:

I've had no trouble ftp-ing with the client Fetch over TCP/IP.

re 177 polytarphs account got spalttered?


#192 of 237 by davel on Thu Sep 4 12:49:10 2003:

/a was full a few minutes ago.  It's now got a little space, hopefully
enough to let me enter this response without crashing something.


#193 of 237 by asddsa on Sun Sep 7 20:38:56 2003:

Like your brain?


#194 of 237 by keesan on Tue Sep 9 21:53:55 2003:

A friend with an email account at mymailbox.com reports that every mail he
gets from grex (but not my ISP), including my account and jdeigert, arrives
in 4-7 copies.  What might be causing this?  Other people don't tell me they
get multiple copies of mail from me.


#195 of 237 by keesan on Tue Sep 9 22:17:26 2003:

myrealbox.com not mymailbox.com


#196 of 237 by gelinas on Wed Sep 10 01:59:49 2003:

He should look at the full headers of the copies, to compare the lines that
begin "Received:"  The ones at the bottom should be the same in every copy,
but then there will be some that have different time-stamps.  Those lines will
show where the transfer is failing.

Most likely, a machine passes it on, but then does not get the acknowledgement
of receipt, so it re-queues the message, to try again later.  The machine that
received, but did not acknowledge, the message delivers it.  Result: the
message is duplicated when delivery is attempted later.


#197 of 237 by asddsa on Wed Sep 10 13:14:31 2003:

No wonder sendmail uses so much CPU all the time.


#198 of 237 by russ on Thu Sep 11 00:33:41 2003:

Very oddly, when ssh'ing to Grex I only *sometimes* get the message
that Grex is lying about the size of its private key.  Is there any
mechanism I could use to confirm the key and rule out funny business?


#199 of 237 by jaklumen on Thu Sep 11 01:34:54 2003:

I'm not sure what it is, but I had some problems with Backtalk... I 
had to put my password in several times at a few points to get in and 
through the bbs.


#200 of 237 by jep on Thu Sep 11 01:41:03 2003:

Yes, I'm getting the same problem.  I just gave up on Backtalk after
encountering it several times.  If I exited from all of my IE windows,
then started one up again and logged into Grex, I could read about 3 items
before getting it again.



#201 of 237 by gull on Thu Sep 11 02:26:31 2003:

I've noticed that happens a lot when Grex's CPU load is very high.  I
suspect something is timing out.

#203 of 237 by malymi on Fri Sep 12 00:56:55 2003:

re 184:  i would suggest using kermit or x/y/z-modem across your tcp
connection, but that appears reserved for dial-up users (foolishly so
imo).


#204 of 237 by newjp2 on Fri Sep 12 02:35:27 2003:

A response when Jamie begs the Grexers for some loving:

Would a kind Grexer with the rootkey please reset the password for jp2?  To
authenticate me, please call the number shown in !f jp2.

Thank you, <hug>

#206 of 237 by davel on Fri Sep 12 12:18:46 2003:

Try reading (or running, if you're telnetted in) /usr/local/bin/sz, & you'll
see.


#207 of 237 by scott on Fri Sep 12 12:40:47 2003:

Send mail to staff@cyberspace.org, Jamie.


#208 of 237 by mynxcat on Fri Sep 12 13:43:32 2003:

Aww, Jamie hugs are the best. Jamie, try emailing staff with the request.


#209 of 237 by gull on Fri Sep 12 14:12:34 2003:

Traditionally none of those protocols have worked well over telnet
because telnet is not transparent, and often not 8-bit clean.  ssh is,
if you disable the escape character with "-e none".


#210 of 237 by katie on Fri Sep 12 18:35:43 2003:

What does it mean when only certain people who try to email me get
"permanent fatal error" messages? 


#211 of 237 by gull on Fri Sep 12 19:41:46 2003:

Are they getting error messages with bible quotes in them?


#212 of 237 by lynne on Fri Sep 12 20:43:38 2003:

That you're a femme fatale?  :)


#213 of 237 by albaugh on Fri Sep 12 22:21:38 2003:

When I have seen those bounces, it was usually due to a temporary connection
problem, "temporary" being variable...


#214 of 237 by newjp2 on Fri Sep 12 23:22:38 2003:

I emailed the staff on like, Aug 29.


#215 of 237 by gelinas on Sat Sep 13 02:58:12 2003:

(It looks like /var/spool/mail is a bit full.)

#218 of 237 by mynxcat on Sat Sep 13 23:39:10 2003:

I thought you left?


#219 of 237 by dah on Sat Sep 13 23:53:35 2003:

I THOUGHT YOU WERE A WOMAN


#220 of 237 by janc on Sun Sep 14 02:04:24 2003:

I've never seen /var/spool/mail full before, so I had to improvise.  I
found some files I could safely delete or move to temporarily make some
space.  Valerie started a reap, which should end up deleteing half the
accounts on Grex (it's been a long time since we ran a reap) and making
plenty of space everywhere.

The shortage of space on /d was pretty much just one user.


#221 of 237 by jlamb on Sun Sep 14 02:25:52 2003:

resp:218   That's another problem i have.


#222 of 237 by asddsa on Mon Sep 15 15:39:05 2003:

re 220 You should run reaps more often. Or buy more hard drives.


#223 of 237 by gull on Tue Sep 16 14:37:39 2003:

Grex should consider upgrading its ancient version of Pine.  Versions
earlier than 4.57 have a remotely exploitable security hole.


#224 of 237 by oval on Tue Sep 16 14:44:58 2003:

and use nano instead of pico.



#225 of 237 by remmers on Tue Sep 16 15:50:43 2003:

Haven't struggled with it myself, but my impression is that updating
Pine is non-trivial on our ancient OS.

Installing "nano" shouldn't be a big deal.  I'll look at it when I
get time, unless some other staffer beats me to it.


#226 of 237 by goose on Tue Sep 16 17:55:58 2003:

Use elm. It's the best.


#227 of 237 by asddsa on Tue Sep 16 22:01:14 2003:

Why not use !mail ?


#228 of 237 by dah on Tue Sep 16 22:16:08 2003:

Yeah, why not?


#229 of 237 by rcurl on Thu Nov 20 07:29:05 2003:

I have been a supporter of Grex in the past by having several small
non-profit organizations with which I have been associated join Grex and
use it at least as their website and board mail reflector. The latter,
however, has become untenable because of spam. There is nearly ten times
more spam being distributed to the boards than board correspondence. Is
there any hope of soon having access to a filter here for spam? I will
probably move an organization off Grex (and thereby cancel membership)
unless there is some recourse against this avalanche of junk e-mail.



#230 of 237 by gull on Thu Nov 20 15:07:30 2003:

It may not get better elsewhere.  My Grex account is actually on the low end
as far as the amount of spam I get.  My ameritech.net account gets over 50
spams a day, and has since before I started using it!  My work account gets
about 100 a day, about 90% of which is caught by a statistical filter.

I agree that Grex needs better spam filtering, but I want the ability to
turn it off if I choose to.  I've had too many bad experiences with mail
disappearing because of spam filters -- no bounce message or anything, just
disappearing into the ether with no warning.


#231 of 237 by gelinas on Thu Nov 20 16:25:05 2003:

(NB: This is the System Problems item from Summer, 2003, not Fall, 2004, so
it doesn't have quite the audience the item in the current agora would get.)


#232 of 237 by rcurl on Thu Nov 20 16:37:30 2003:

(I don't think Fall 2004 will have much audience - yet - either.......but
thanks for the poke in the ribs 8^})


#233 of 237 by rcurl on Fri Nov 21 16:18:06 2003:

Could Grex use the Spamhaus Block List (SBL) to block spam? See
http://www.spamhaus.org/sbl/howtouse.html


#234 of 237 by jhudson on Tue Nov 25 15:33:34 2003:

We will have to put a kludge in it as cyberspace.org sometimes ends
up on various spamblock lists. Might be worth considering though.


#235 of 237 by rcurl on Sat Dec 6 14:12:09 2003:

I'm telnetting in from Madeira Beach FL. I cannot connect to Grex directly
as I get a "not responding" response, but I have telnetted into CAEN, and
then telnetted over from there. Why won't Grex respond directly? 



#236 of 237 by jhudson on Mon Dec 8 20:17:34 2003:

Grex is responding very slowly. I'm not surprised you are having 
trouble.


#237 of 237 by albaugh on Mon Dec 8 20:27:59 2003:

In fact the problems are so bad that this report got stored in *old* agora!
