Grex Helpers Item 138: Grex System Problems - Winter 2004/2005 [linked]
Entered by i on Wed Dec 22 09:08:13 UTC 2004:

This item is for system problems.  If something on Grex isn't working 
right (line noise on a modem, weird behavior from a program, etc.), 
this is the place to announce it.  Except for security holes.  If you 
find a hole in system security, mail information about it to "staff".

Nethack doesn't work.  I get an error:

No write permission to lock perm!

I think I fixed it, jep; let us know here.

Backtalk bounced an attempt to post in coop.  gave the following error 
message:

"Oops! The authors of Backtalk are deeply sorry to confess that our 
program has failed to operate correctly. This is due to an error in 
Backtalk itself, or in one of Backtalk's script files, or in the 
configuration of the system. It is probably not due to anything you 
might have done. The page below contains an error message and a 
detailed dump of the state Backtalk was in when the error occurred. 
This may be useful to anyone trying to fix the problem.

All this information has been logged, but it may still be helpful for 
you to report this error and the circumstances under which it occurred 
to the system administrators. 

Thanks for your assistance in getting the bugs out of this 
conferencing system. We sincerely and humbly beg your forgiveness.

I re-entered the post and it took the second time...

Had to edit my .cshrc to point to where global.cshrc is now located, 
/usr/local/etc instead of /usr/local/lib


#5 of 870 by aruba on Wed Dec 29 07:47:18 2004:

Ah, thanks for those locations, Scott.  I have now done the same.
Maybe someone should symlink them to /usr/local/lib (where they used to be).


#6 of 870 by richard on Wed Dec 29 08:08:30 2004:

when I telnet in, it says "user not authenticated, using plain text"????


#7 of 870 by i on Wed Dec 29 12:22:12 2004:

Looks like i've got a 0-bit disk quota on /tmp, which is killing mail
programs.

nharmon@grex ~ > mnet
ssh: connect to host m-net.arbornet.org port 22: No route to host

I've tried it with other hostnames, same problem. I think my membership is
still current too. :P


#10 of 870 by gelinas on Wed Dec 29 13:48:08 2004:

Check which ssh you are using Nathan; there may be more than one, and you
may be using the wrong one.

I noted that my path included /usr/ucb , which does not exist, and did not
inlcude /bin , which has stty, among other things.


#11 of 870 by dpc on Wed Dec 29 14:09:27 2004:

I was able to read my mail without any problems.  Hoewwever,
when I quit mail by typing q, here is what I got:

SHELL environment variable is wrong!!!
try this:               "define" "shell" "/bin/sh"

I haven't tried this because I don't know 
if I should.

Also, my backspace key no longer deletes characters.  Instead,
I get a stream of ^H.

Finally, at the lower left hand corner of each screen of text,
I see "byte abcd".  This vanishes when I go on to the next screen.

These are *really small* problems.  Congrats to janc and others
for the successful transfer to NextGrex!


#12 of 870 by dpc on Wed Dec 29 14:18:53 2004:

Ahaa--the "byte abcd" replaces the reverse-video --Moerre--
that used to appear on my screen.


#13 of 870 by blaise on Wed Dec 29 15:29:17 2004:

Backtalk is continuing to give the 
"ERROR: index_new_resp called with response number 218103807 
executing "post_resp" on line 113 of pistachio/response.bt"
message, but is posting the response anyway.


#14 of 870 by davel on Wed Dec 29 15:37:17 2004:

gracel & kingjon report being unable to read their mail because of a quota
exceeded on /tmp.  I'm not sure "huge" is a good description, and as most
of it is recently-arrived spam I don't see how it's avoidable.  Shouldn't
the quota on /tmp be big enough to allow reading mail?

Grace also is experiencing the problem with her backspace being set to ^?
instead of ^H.  Are we going to have to fix this in one of the setup files?
And she also sees the
        SHELL environment variable is wrong!!!
        try this:               "define" "shell" "/bin/sh"
message.  FWIW, her shell is /usr/local/bin/bbs; I suspect that this is
the problem.  IIRC, on old Grex the shell for people who wanted to come up
in bbs was something that set up the user's environment correctly and then
exec'd bbs, wasn't it?  She has a .profile which sets PATH and PAGER (which
also is not working) and does stty, but it's not getting executed.

I'll fix her up (by changing her shell), assuming I can - I'm assuming that
the program to do that will work.  But I suspect that a lot of people will
be affected.  (There are almost 600 entries in /etc/passwd with
/usr/local/bin/bbs as the shell.)


#15 of 870 by remmers on Wed Dec 29 15:44:00 2004:

I think Dan Cross just fixed the shell problem with bbs.

#17 of 870 by eprom on Wed Dec 29 16:08:16 2004:

Is anyone else having problems with there .procmail filter? Do I need to
change something in my .forward? 


#18 of 870 by nharmon on Wed Dec 29 16:10:40 2004:

When opening pine,  get the following:

     [Folder vulnerable - directory /var/mail must have 1777 protection]


But I don't know why it needs to be globably writable. :/

BTW, my previous ssh problem, I was using /usr/bin/ssh. /usr/local/bin/ssh
works better. Strange.


#19 of 870 by keesan on Wed Dec 29 16:18:52 2004:

I just reported the same problems as in 17 and 18 in coop.  And I am not
getting ANY mail including two I sent myself just a few minutes ago, one of
which should have gone to /dev/null.  I will try turning off procmail.


#20 of 870 by keesan on Wed Dec 29 16:24:02 2004:

My mail is no longer in /var/spool/mail/k/e/keesan (which I had set up
.procmailrc to point at) but in /var/mail/keesan.  I have edited .procmailrc
and sent myself another test mail.


#21 of 870 by keesan on Wed Dec 29 16:32:59 2004:

Changing to /var/mail/keesan did not fix my problem of not getting any of my
test mails.  I had to turn off procmail by putting # in front of the line in
.forward.  Procmail is still in /usr/local/bin as it should be.  I get mail
now but most of it will be spam.  


#22 of 870 by keesan on Wed Dec 29 16:36:45 2004:

My first spam just arrived, now that I have no filter.  Can the inbox limit
be temporarily increased until procmail can be made to work again?  50 spams
a day won't leave me room for any mail.  


#23 of 870 by gull on Wed Dec 29 16:42:59 2004:

I got the following crash dump from Backtalk when I tried to post a
response in the "diy" conference.  The response was posted anyway.

#24 of 870 by janc on Wed Dec 29 16:56:52 2004:

The backtalk crashs and the weird "response not posted" message from fronttalk
are the same problem.  They have to do with byte-order problems in the sum
files for the conferences.  Old and new Grex stored binary files with opposite
byte orders.  So when we copied over the sum files from the Sun, they arrived
all backwards.  Theoretically both Picospan and Backtalk are supposed to be
able to detect the backwardness of the sum files and compensate for that. 
Looks like Picospan is succeeding but Backtalk is slightly confused.

Easiest fix is to regenerate the sum files.  You can just delete them.
Picospan will complain about missing sum files until someone does a "fix sum"
command in the conference to regenerate it.  Backtalk automaticaly regenerates
them if they are missing.

#26 of 870 by janc on Wed Dec 29 17:23:16 2004:

I removed all the old sum files, and had backtalk regenerate most of them.
I think I probably missed regenerating some.

If you see a conference where Picospan complains about there being no sum
file, there are two fixes.  Either a fairwitness can say "set summary" in
Picospan, or any user can join the conference with Fronttalk or Backtalk.

Picospan will still work without a summary file - it'll just be slower.


#27 of 870 by keesan on Wed Dec 29 17:35:59 2004:

While trying to get procmail to work (now it lets through ALL my mails) I
attempted to logout and then login as a different user and logout got me a
NO CARRIER with no opportunity to login again.  I had to redial.


#28 of 870 by blaise on Wed Dec 29 17:37:05 2004:

Just "|/usr/local/bin/procmail" without the quotes works fine; I don't
know whether the quotes would be needed if you added a parameter.


#29 of 870 by keesan on Wed Dec 29 17:43:16 2004:

I just emailed myself from a non-grex account (after making sure keesan was
no longer on my white list) with subject line 'viagra cialis meds', all three
of which words are in my subject filters, and the mail went to my inbox.  I
have the double quotes - should I remove them?  It is acting as if procmail
is not there.  I changed both .forward and the MAIL line in .procmailrc and
these are both globally readable.  I also got another spam not from me in the
inbox.  My filter, when working, gets about 95% of spams.  Would one of you
experts mind trying out a very simple procmail setup to see if it works for
you?  


#30 of 870 by janc on Wed Dec 29 17:55:39 2004:

Yes, new Grex will hang up on logout.  I think this is hard to change.


#31 of 870 by blaise on Wed Dec 29 18:01:43 2004:

I have my filter working.  (I copied yours, commented out everything
except the first and last conditions, and changed them to something
simple I could work with.  My filter puts anything from my spamcop
account into a folder named Mail/spamcop [in Maildir format], and
forwards anything else to my spamcop account.)

MAIL=/var/mail/blaise
LOGFILE=$HOME/Mail/from
VERBOSE=off

:0
* ^From:.*jtrigg.*@spamcop.net
$HOME/Mail/spamcop/

:0
!jtrigg+cyber@spamcop.net


#32 of 870 by keesan on Wed Dec 29 18:45:35 2004:

I just got one REAL spam (not the ones I was making up and sending from
myself) sent to /dev/null.  So it appears to be working.  I don't know why
mails from keesan@ are going into my inbox no matter what the subject line.


#33 of 870 by keesan on Wed Dec 29 18:46:32 2004:

Jan, why won't the new grex allow logging out and in again?


#34 of 870 by blaise on Wed Dec 29 19:12:44 2004:

Sindi, mails from *@grex are whitelisted before cialis is blacklisted. 
(The grex whitelist is in the middle of the blacklists.)

#36 of 870 by keesan on Wed Dec 29 19:38:35 2004:

I just removed from my white list 'org edu grex keesan' as From's and procmail
just caught a spam that I sent to myself.  But I still cannot view my log file
(/mail/from) from within Pine.  I can view it with less so it is not a problem
but it may be symptomatic of something not being set up right.  I could view
the first time but ever since it has been blank.  I now have a choice of 1
or 2 in 'from', both blank.


#37 of 870 by blaise on Wed Dec 29 20:05:23 2004:

It's possible that the new version of pine is more picky about mbox
format (which the procmail log isn't but is similar to).


#38 of 870 by janc on Wed Dec 29 21:26:13 2004:

Old Grex was modified not to hang up.  It used to confuse a lot of
people who were used to the standard behavior.  It would probably be
possible to figure out how to modify new Grex to do that, but I think
it'd be a lot of work.

Fronttalk directly executes backtalk when used on Grex.


#39 of 870 by glenda on Wed Dec 29 21:56:45 2004:

When I log in I get a message that I have mail, when I go into elm it says
I have 0 messages.
