Ftp keeps timing out.

psftp gets me just past the Password prompt, then it says something to the
effect of sftp-server: command not found, could not connect.


#247 of 286 by krj on Sun Sep 19 04:31:21 2004:

While using party tonight, I kept getting disconnected; eventually the 
network connection appeared to go down solidly.  I dialed in direct
to enter this.  (It takes about 79 (?) seconds to log in on a direct
dial, too.)

My telnet connections continue to be unstable, though I was able
to connect long enough to enter this...


#250 of 286 by marcvh on Sun Sep 19 18:51:02 2004:

My telnet is repeatedly being disconnected also.


#251 of 286 by mcnally on Sun Sep 19 22:03:17 2004:

  I was disconnected last night and unable to log in this morning.


#252 of 286 by xpandora on Sun Sep 19 23:21:09 2004:

I get a connection attempt to (TCP Port 6346) from 142.163.11.15 
whenever I try to log on.It also takes around 70-80 seconds for a 
prompt.


#253 of 286 by xpandora on Sun Sep 19 23:23:59 2004:

got the same connection attempt just as i hit the submit button on my 
previous post.


#254 of 286 by krj on Mon Sep 20 02:43:11 2004:

Connectivity has been exceptionally unstable for the last couple of 
hours.  Type five lines in party at mosst, and then log in again....


#255 of 286 by mcnally on Mon Sep 20 04:09:48 2004:

  re #252, 253:  That's very odd, but probably a coincidence..
  TCP port 6346 is used for the P2P file-sharing program gnutella
  and "!dig ptr 15.11.163.142.in-addr.arpa" shows the host that's
  trying to connect belongs to a Canadian ISP, sympatico.ca, probably
  a user in Newfoundland.

  > 15.11.163.142.in-addr.arpa.     86354   PTR     stj515.nf.sympatico.ca.

  I'll check my firewall logs tomorrow to see whether I'm getting the
  same behavior but I suspect I won't be.


#256 of 286 by tod on Mon Sep 20 18:10:27 2004:

These sporadic lag sessions that last more than a minute every 4 minutes SUCK.
People keep getting booted off.


#257 of 286 by keesan on Mon Sep 20 18:18:02 2004:

I got 2 minute lags three times while telnetted to another shell account and
writing a single mail, not a terribly long one.  More time down than up.
Telnetted from grex, I mean.  I can't telnet there directly from DOS, it does
not like my DOS telnet program.


#258 of 286 by aruba on Mon Sep 20 20:34:15 2004:

I got a lot of long pauses today too.


#259 of 286 by cmcgee on Tue Sep 21 01:04:43 2004:

I got lagged completely off three times today, while dialed in, and was unable
to complete a short email.

Then, just now, it took more than 3 minutes to get from the welcome screen
to the login while dialing in.


#260 of 286 by gull on Tue Sep 21 03:03:58 2004:

Grex has gotten so unreliable in the last few months that, for the first
time since I created my account nine years ago, I've given up on using
it for email.


#261 of 286 by albaugh on Tue Sep 21 04:07:36 2004:

I'll give things the 4Q to clear up...


#262 of 286 by rcurl on Tue Sep 21 05:38:23 2004:

I've nearly done the same thing myself. It is not only the spam and the
downtime, but also that there have been no upgrades on handling file sizes
and types, while the rest of the online world is bloating. 


#263 of 286 by i on Tue Sep 21 12:22:39 2004:

I just power cycled the DSL modem.  Hopefully that'll cure it for a while.


#264 of 286 by dpc on Tue Sep 21 13:18:00 2004:

What Rane said.


#265 of 286 by bru on Tue Sep 21 13:32:36 2004:

I tried dialing in today and got an error.


#266 of 286 by keesan on Tue Sep 21 16:18:50 2004:

Someone that I send an email to complained they never got it.  I sent it again
today directly, and also forwarded via another shell account.  They just wrote
back that they got the SECOND mail.  Is grex on Spamcop's blacklist again?

I got connected dialin after the usual wait.  I tend to go wash dishes.

I hope that the new Grex has a version of Pine that can handle HTML (with
lynx).  A  friend of mine using grex for email has an ISP account specifically
to forward her html emails to because she cannot figure out how to deal with
them here.  It expires in November.  


#267 of 286 by aruba on Tue Sep 21 17:16:42 2004:

Thanks, Walter, for cycling the modem.


#268 of 286 by mary on Tue Sep 21 22:34:14 2004:

I'm not sure if this was announced somewhere or not, but folks should be
aware that if they have any files in their directories they'd mind
losing, they should get them off Grex or at least have a safe backup
stored elsewhere.  The partition with user directories hasn't been
successfully backed up since sometime in 2003.  And STeve thinks this
might be our next disk to fail. 

If I got that wrong, someone with more information please set the
record straight.  


#269 of 286 by slynne on Wed Sep 22 02:07:08 2004:

Thanks for the reminder, Mary


#270 of 286 by tod on Wed Sep 22 17:12:06 2004:

Would someone on staff please respond to item 196 in the coop cf? Thanks!


#271 of 286 by albaugh on Wed Sep 22 18:03:45 2004:

Are there any prospects for user partition backups any time soon?


#272 of 286 by gull on Wed Sep 22 19:36:36 2004:

I think Grex's policy has always been that the user partition is not
backed up on any regular basis.  As long as I've been here there have
been warnings not to store anything too important there.

It doesn't take too long to tar up all your files and then use FTP or
SCP to copy them to your home machine.


#273 of 286 by rcurl on Wed Sep 22 19:44:56 2004:

I'd like some help in doing that. I can do it file by file, but can I just
compress and download my whole directory, and open it as needed on my
home Mac (OS X)? If so, how (e-mail me, if it convenient). 


#274 of 286 by gull on Wed Sep 22 20:01:08 2004:

I'll post it here, so that other people can benefit, too.

To get all your files into one tarball:

Change to your home directory and type 
   tar cvf mystuff.tar .

If you then want to compress it, type
   gzip mystuff.tar
and you'll end up with a file called mystuff.tar.gz.

I'm not sure what the best utility to open this on OS X would be, though
I bet you can extract it in a terminal with
   tar xvzf mystuff.tar.gz
but if you want a GUI solution, something like StuffIt may work.


#275 of 286 by gull on Wed Sep 22 20:02:05 2004:

(Incidentally, I should probably point out that there's a period on the
end of that first command line.  Don't forget it; it's there to indicate
you want everything in the current directory.)


#276 of 286 by keesan on Wed Sep 22 20:13:35 2004:

How about tar zcvf to produce .tar.gz ?
When I telnet here with Kermit it gives me some helpful hints about what is
taking so long:  The Telnet server is not sending required responses:

WILL TERMINAL-TYPE
WILL NAWS
WILL NEW-ENVIRONMENT
WILL COM-PORT-CONTROL

Does this mean there is a software problem at grex?


#277 of 286 by mcnally on Wed Sep 22 20:48:08 2004:

 re #274: 

 > Change to your home directory and type 
 >  tar cvf mystuff.tar .

 What happens when the tar command tries to add ./mystuff.tar to 
 the archive it's building in ./mystuff.tar?

 Another problem (well, not really a *problem*, but potential
 complication is that when files are extracted from the mystuff.tar
 file they'll be dumped unceremoniously into the directory where
 the tar extract command is run.  You ought to either tell the
 user to extract in a fresh directory or else back up a level before
 building the tar file, e.g.

    cd ~/..; tar cvzf /tmp/grex_homedir_$USER.tar.gz $USER

 (in most shells, anyway..)


#278 of 286 by mcnally on Wed Sep 22 20:50:54 2004:

  Also, while tar is the most convenient archive utility for most
  Unix users, PC and Mac afficionados may find zip to be more useful
  for them (Mac users can unpack zip archives using UnStuffIt; I'm
  not sure how well it handles gzipped or bzipped tar files.)


#279 of 286 by tod on Wed Sep 22 20:52:46 2004:

tar is nicer because it retains the perms info


#280 of 286 by mcnally on Wed Sep 22 21:36:49 2004:

  I agree that tar is the way to go if you're going to be extracting
  under Unix or a Unix-like system..


#281 of 286 by mcnally on Wed Sep 22 21:39:42 2004:

  Based on other investigation I doubt it's a telnet- or telnet-and-ssh-
  specific problem.  The same 79 second delay seems to affect outgoing
  SMTP connections, too, for example.

> Does this mean there is a software problem at grex?

  It's definitely a configuration problem or software error of some sort.


#282 of 286 by tod on Wed Sep 22 21:50:33 2004:

Something in inetd perhaps?


#283 of 286 by gelinas on Thu Sep 23 02:43:02 2004:

No promises, but it looks like I'll have some time on Friday to attempt
a back-up of grex.  I hope folks can stand losing it for a day during
the week.  ;/


#284 of 286 by rcurl on Thu Sep 23 06:43:52 2004:

From my reading of recent responses, there seems to be some questions, or
suggestions, inre what gull said in #274. What should I take as the
current consensus inre my ? in #273? 



#285 of 286 by gull on Thu Sep 23 13:13:00 2004:

Re resp:277: The version of tar that Grex has is smart enough not to add
the archive it's creating to itself...as long as you *don't* use the z
flag.  That's why I didn't use it as was suggested in resp:276.  I
thought about telling people to create the tar file in the /tmp
directory, but I didn't for two reasons:  There's not much room in /tmp,
and people would inevitably leave the file lying around there where
anyone can read it.  I agree with your other comments.

Re resp:284: Any of the suggestions that have been given will work. 
There's More Than One Way To Do It(tm).
