re #474:
> we've been dealing with network problems since last summer
the recent problems seem qualitatively different than the ongoing outages
that were occurring previously.
re #470:
> maybe grex would be better off back on the old server for the time being.
That would take a major amount of work to move back to the old server
and then another major amount of work when the new server was judged
to be ready for prime time. Worse, one might complete all that work
only to find that the source of the problem lay elsewhere, as seems to
be the current prevailing opinion among staff.

#474...gelinas, what mcnally said...the problems have clearly gotten worse,
much worse, since the switch to the new server. I understand the work that
would be involved in going back to the old server, but how else can the new
server's role in the current problems be conclusively proven?

Regarding the particular variety of intermittent screen freezing (if there
are different kinds) that we have been observing recently, when I'm logged
onto Grex and my screen happens to be frozen, are all the other screens of
other logged on Grex users also frozen <<at that moment>>, or at any given
time are some Grex screens frozen and some not frozen?

Please have some patience, folks. Please. There are multiple
reasons for the problems Grex is having and staff is as anxious to
get them under control as everyone else.
It's my undertanding the machine is moving to co-lo this weekend, if
at all possible. Some of the lag will be helped when robocop is up
and working and Jan is working on that. And the setting are still
being fine-tuned but doing so under the current lag makes that all
the more difficult. Staff is not ignoring Grex right now, really,
they're not. Let's try to be supportive - especially now, when they
have so much to do.
I suppose we could go to our DSL folks and insist it's their fault
and consider not paying the bill, but first we'd have to be sure
it's their problem, entirely. I'd rather we simply work on a
solution and get Grex working right.

In other news, there appears to have been no mail all of
yesterday afternoon, evening and last night.

The problem before was frequent sudden freezeups for mayb 30 seconds while
telnetted. Right now (I am dialed in) things are okay for a minute or so then
I will type something and wait 5 sec for half a line to appear, then after
5 sec another chunk appears A 5-10 character string will appear, then in 5
sec a few more characters, and then suddenly it all works okay again. This
is entirely different from before. Is there some way to hook up any other
grex-type setup to the same DSL modem and phone line to see if the problem
carries over? (An httpd server? Telnetd server? Do I have the terms
right?). At this point nobody would be terribly inconvenienced (more than
currently) if grex were off the air for an hour or two to do such a test.
Can some other computer (say a laptop) be plugged into the serial port via
a serial cable to see if it can telnet to grex? Or work as a dumb terminal?
(I even had this working on my little linux setup once, both ways).

If not all screens are frozen at the same time, then would it be possible
for an online user whose screen is <<not>> frozen to run a Unix script
that would unfreeze the screen of another online user whose screen <<is>>
frozen?

We will move the machine tomorrow, which should, we hope, solve this problem.

Grex is working relatively okay at the moment (the usual telnet lag) but no
incoming mail.

Would staff please check out www.badcaps. net to see if the freezeup problem
is related to bad capacitors? It can Many companies have been putting in
defective caps since 2000. Smptom is 'random and frequent freezes, or freezes
under heavy board activity'. We revived one dead board by replacing 6 cheap
caps. Flaky power supply could cause similar problems - measure voltage.
Measure cpu temperature (we have a remote thermometer). Jim fixed two such
boards and is free this weekend. What manufacturer and model board? What
brand are the large capacitors neqar the power supply (probably four in a
row).

Grex has been moved, to judge by the new IP address, and seems much happier.
Thanks, staff!

The problems with Grex are not related to bad capacitors. The story of
them has been blown completely out of proportion compared with what has
actually been experienced. Motherboards with weird looking capacitors
are most often the fault of poorly made units, and not the dreaded
improperly built type that do exist, but not in the amounts reported.
Thanks to the staff people who moved Grex. Certainly an order of
magnatude faster, if not more than that.

Joe moved Grex during a blizzard to keep the rest of us connected
and happy.
Thank you, Joe.

Wow, on time even! The board we just fixed had several bulging capacitors
out of 10. Jim replaced 6. The bulging ones tested okay, one that looked
okay was completely shorted. You cannot tell just by looking at caps.
Obviously grex is much happier at this new address. I still get the usual
telnet lag but it can nearly keep up with my typing now. About a 2 sec
wait for the cursor to move down one line. Well, maybe it is half as fast
as my typing.

I don't think the telnet lag is any worse than it was last year so the problem
that was plaguing us at the pumpkin seems to be fixed. I am using a 56K modem
(which tends to connect at 33K or at most 39K) and dialins are generally alot
faster. Joe, many thanks for your work on this.
