You know, you run the risk of drowning when you panic. ;) Thanks for the
work and for the update, mcnally

Thanks, slynne ! If only you had a home directory on /c , like all the
sensible people. Really, people should follow my example.

If there is anyone who wants to volunteer to have their home directory
relocated to /c, you can e-mail me privately and I will move it. There's
no need to create a new account to get a homedir on the other drive.
I hope to balance things out so that there's not much advantage (or more
appropriately, so there's no *dis*advantage) either way.

If anyone who gets re-located wants to e-mail me, I'll personally send them
back an e-mail welcoming them to /c and congratulating them on their choice.

Perhaps you could award volunteers with an extra 100K disk space if not enough
people volunteer.

In addition to getting downloads via modem (14.4K) of about 350-450 CPS for
the past few days, 484-0513, I have been getting frequent disconnects (three
in about ten minutes). It is not the phone line or modem, they work fine
elsewhere. I finally gave up and telnetted.

Just curious, why do you dial into Grex when you can telnet instead?

Perhaps the telnet is via dialup to ISP and thus sluggish

Re resp:64: She dislikes the lag caused by dialing in to an ISP and then
telnetting.

Correct on 65 and 67. We have 'free' service via WCC (Jim takes a course
there every year and gets connection for a year) which is erratic, disconnects
us after 62 minutes (or sometimes 10 minutes, no idea why), sometimes
downloads at 0 bytes/sec and frequently at 500 bytes/sec. Grex is now more
predictable. 484-0512 seems to work perfectly (it downloaded at a speed
approaching 2K/sec) but 0513 has been disconnecting me frequently, and
downloads this past few days have been at 350-450 bytes/sec (variable
throughout the same short download). So leave the first line alone and look
for noise or a bad modem on the second line. Someone else reported earlier
that the first phone line was too noisy to dial from another part of Ann Arbor
but I think that got fixed.

Re #68. WCC connection hangs up at times because it is a part of Michnet.
Michnet connections are not always open-ended. You get a token which gives
you a certain amount of connect time. That amount of connect time is
dependent on the number of connections at the time. To tell how much time
you get telnet to timeleft.dialin.mich.net
The differences in download speeds is also dependent on how many people are
connected in via WCC. WCC has a limited bandwidth and often throttles it back
to allow some usage to everyone. I have a real bitch of a time with it when
I am trying to get a lab ready for a new class. The only time I can really
get good through-put is during hours that I (technically) am not supposed to
be on campus. It is a balancing act on whether I work odd times of night,
when I really shouldn't be there or I work more hours than budgeted to get
the job done. Once I get a couple more servers and can do my image flashes
while off the backbone I will be a happy camper.

This week (past few days, anyway), I have been getting speeds ranging from
0 to 500 bytes/sec on a 56K modem, after it claims to have connected at 28.8,
49,333, or 19,200. I can't dial in directly to grex because neither of the
modems has been answering for at least two days (here or from antoher
address). Right now I have been typing a whole line before I see any
characters on teh screen, then a few appear, sometimes half a line. Is this
a WCC problem this week? It has happened frequently the past month or two.
Once in a while I can get a download as fast at 2.4K (not right now, with a
19,200 connection). Why is WCC so overcrowded in the summer?

I just measured 0-100 bytes/sec, average 40, in the past few minutes.
(It is behaving a bit better now, I can type and see things within 2 seconds
right now). Have the recent storms messed up the phone lines or knocked out
a computer at WCC ,or the grex modems?

Just got disonnected (after telnetting to the site that told me I had
unlimited time) and dialied in again and was connected at 16,800- a new
record. I cannot see anything until a few lines after typing it.
Sometimes 15 sec later.

I am not currently working regularly, taking most of the summer off. So I
don't know much of what is currently going on. I do know that they are doing
a lot of updates and reconfigs for the fall semester. The banner system and
other parts of the network are being taken down frequently, especially from
Friday afternoon through Saturday to Sunday afternoon/evening. Starting
Monday I will be working 40-48 hours a week for the next three weeks for
special "Train-the-Trainer" courses so may hear more. I do know that we do
have a lot of beginning computer classes that run through Spring/Summer
semesters.
Michnet is also getting rid of some of their modem banks with the
corresponding usage problems.

Things are much better Saturday morning (50,666 connection, no lag). I will
be prepared for poor connections on weekends. I hope someone can check out
the grex phonelines and modems soon.
