Grex Helpers Item 113: Grex System Problems Item [linked]
Entered by i on Tue Sep 24 23:27:36 UTC 2002:

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".

248 responses total.

fag.

You say that like it's a bad thing.

(finally. someone gets it.)


#4 of 248 by keesan on Wed Sep 25 11:52:28 2002:

The instructions for using fall bbs scrolled by without me hitting the space
bar.  Might be hard for beginners to read them.  Is this normal?


#5 of 248 by bhelliom on Wed Sep 25 14:06:45 2002:

Define 'normal'.

You know... will her friends shun her and strangers giver her dirty looks for
it, or is she still an ordinary, productive member of society?

:)


#8 of 248 by jmsaul on Wed Sep 25 17:37:06 2002:

How can you be a productive member of society without a scrollback buffer?


#9 of 248 by tsty on Wed Sep 25 19:59:41 2002:

flash memory?


#10 of 248 by other on Wed Sep 25 20:52:07 2002:

Ahh, the subtle secrets of life revealed.  Thanks, Joe! (resp:8)


#11 of 248 by drew on Thu Sep 26 22:08:46 2002:

A quick question: Exactly what extra output is provided by the -d (debug)
option of the bbs command, and is it sent to stdout or stderr?

Perhaps it can fulfill a role that I am thinking of requesting a modification
for.


#12 of 248 by ea on Fri Sep 27 23:37:50 2002:

I don't know that this is necessarily a problem, but I was rather
startled this evening when logging into Grex (using backtalk), and
discovering that the default light yellow had been replaced by a light
green.  Has Jan installed a new version of backtalk?

(it's an interesting change. I don't have an opinion as to whether it's
good or bad)


#13 of 248 by janc on Sat Sep 28 04:13:33 2002:

It's an accident, I think.  I thought I had fixed that when I installed the
new backtalk, but it doesn't seem to be fixed.  Not sure what happened.
Need to go back and re-yellow it.


#14 of 248 by janc on Sat Sep 28 04:15:26 2002:

OK, should be yellow again.


#15 of 248 by danr on Sat Sep 28 18:52:50 2002:

I liked the green better.


#16 of 248 by janc on Sat Sep 28 20:46:43 2002:

When I finish debugging the next release you can have it better - user
definable colors.


#17 of 248 by drew on Sun Sep 29 05:32:12 2002:

    Apparently, the -d option sends nothing to stderr.

    Could an option be added to Picospan, off by default but that can
be turned on, that would send out to stderr (not stdout) something like:

        ("%s  %d  %d\n", confname, item, response) ?


#18 of 248 by mcnally on Sun Sep 29 08:49:50 2002:

  You could set your isep/rsep values to begin with some virtually-
  guaranteed-not-to-occur-normally string to make them easy to pick
  out and pipe virtually everything through a script which would kick
  out the line to stderr whenever one was encountered.

  I thought we didn't have a modifiable copy of picospan here on Grex,
  so requests to add even something as quick and easy as that might go
  unfulfilled.


#19 of 248 by aruba on Sun Sep 29 15:34:02 2002:

What Mike said is what I do.  I wouldn't hold your breath waiting for
Picospan to change, Drew.  What is it you want to do?


#20 of 248 by drew on Mon Sep 30 19:16:06 2002:

Most times I read bbs by logging in and routing all output to a file via

        bbs <bbsin.fil >newresp.grx

then either sz or ftp the file to my machine, depending on how I'm connected.
Of late, some of these reads have been taking a while, and it would be nice
to have a running report of the progress so there's something else besides
inert screen. And since stdout is being routed to the file, it stands to
reason that the progress data should goto stderr.

(Teeing the output of course is not practical - would increase the run time
too much.)


#21 of 248 by keesan on Mon Sep 30 21:02:48 2002:

Lynx does not seem to be working, either to my ISP or to UMICH.edu.


#22 of 248 by aruba on Tue Oct 1 01:36:02 2002:

Drew - why don't you write a little C program to propcees the output from
bbs, write it out to stdout, and write a message to stderr now and then to
report progress.  You could do it with AWK, too, but C might run faster.
Then your command would be something like:
/----------------------------------------\
| bbs <bbsin.fil | myfilter >newresp.grx |
\----------------------------------------/

What's a startfile?
> lynx www.cyberspace.org

Alert!: Unable to connect to remote host.


Looking up www.cyberspace.org first
Looking up 216.93.104.35
Making HTTP connection to 216.93.104.35

lynx: Can't access startfile http://www.cyberspace.org/


#24 of 248 by keesan on Wed Oct 2 12:57:32 2002:

Lynx has been flaky again since last night.  Sometimes it cannot access the
'startfile' (the name of the file that you type in when you start lynx) and
sometimes it can do so, but then it will not access any links to that page.
I have managed to go into lynx and, when it is misbehaving less, type g (go
to) and then the URL, and it goes to that site but then not any links to it.
I got a message at one point (when it would not even do that) that there were
server problems.  So I guess grex will just have to be patient.

Try mnet.  From Ann Arbor dial 661-1234 (?), for login type mnet, password
Enter, then next time it wants login type newuser and fill in the form and
pick a password.  Mnet has a very fast running lynx.


#25 of 248 by gull on Wed Oct 2 15:46:51 2002:

Sounds like maybe the proxy is acting up again.


#26 of 248 by scott on Wed Oct 2 20:14:45 2002:

Web stuff should be working now - dang sent some emails about his problem
fixes for the proxy server.


#27 of 248 by keesan on Wed Oct 2 22:34:52 2002:

It works just fine today.  Grex is also lots lots faster than all week.


#28 of 248 by gelinas on Thu Oct 3 22:54:32 2002:

There seems to be a problem with the telnet queue, so I've sent a message to
staff.  SSH can't get a pseudo-tty, and there were (last I checked) 34 remote
users and 15 waiting in the queue.


#29 of 248 by jmsaul on Thu Oct 3 23:09:08 2002:

I was just going to ask about that.  The queue went down awful fast, too; over
a minute or so:

Waiting for a free port (? for help)
...23
...21
...20
...19
...18
...15
...10
...9
...6
...1


#30 of 248 by remmers on Fri Oct 4 01:08:26 2002:

I noticed the same behavior a few days ago -- can't log in with SSH,
and a big queue that goes down to nothing very fast.  Not many people
were logged in, so there shouldn't have been a queue at all.

Tried again a few hours later and the problem had gone away.


#31 of 248 by jmsaul on Fri Oct 4 01:33:34 2002:

Same here.


#32 of 248 by gelinas on Fri Oct 4 03:59:14 2002:

Joe, John, if you don't know of it, you may find

        fixwait -L

interesting.  It shows that the queue may still be there even though it
gets processed pretty quickly.


#33 of 248 by jazz on Fri Oct 4 13:20:26 2002:

        It really is what (I presume) they were thinking, not just a high
wait queue ... look at the 'fixwait -l' output below:
