I can't run Pine because (I think) Grex is unable to find my terminal in the
utmp file. What does that mean?

Caveat re resp:678 - Fronttalk is beta, so expect some rough edges if
you use it. However, Jan's been putting a lot of work into it recently
and it's getting to be in good shape. There's an item in the Garage
conference to discuss Fronttalk bugs and features (item:garage,5).

Telnet and ssh both work for me. I want to get some cat3 telephone cable. I
have cat5, but I don't think that will work for telephone.
Of course, I could put two jacks on each end of the cat5, instead of one, and
use one cable for both modems. :)

CAT5 will work fine. It's just more expensive. CAT3 and CAT5 both have
four twisted pairs (eight conductors), incidentally -- CAT5 just allows
for more bandwidth.
In either case it's just a matter of crimping the right connectors on
the ends (or attaching the right jacks, as the case may be). For best
noise rejection, don't "split pairs" -- use two wires from the cable
that are twisted around each other for the phone line. Only the two
center conductors of a phone connector actually do anything, on a
single-line phone, and in fact you'll find a lot of commercial phone
cords only have two wires.
So, for a single-line phone, the connector would look like this:
--AA-- (Where - is empty, and A are wires from one pair of the cable.)
For a two-line phone, it would look like this:
-BAAB- (Where A is from one pair, and B is from another.)
Incidentally, the two wires that are used on a phone connector
correspond with the two unused positions on a 10baseT ethernet
connector. I suspect this is to help protect ethernet equipment from
damage when some clueless person accidentally plugs a phone line into it.

Hmm. I just found this website that probably explains it in a less
confusing way than I just did:

ummmmmmmmmmmmmmmmm, ethernet wiring, iirc, is *not* wired correctly
for telephone use. oh, wait, that is incorrect since polarity
no longer matters to the modern phone newtwork.
this applies to 4-conductor cable.
gull's #686 is correct for phones, single-pair and two-pair.

It's true that ethernet wiring isn't quite the same as phone wiring, but
the cable itself is fine -- the difference is in how the ends are
attached. You're going to have to change the ends anyway, unless your
phone stuff has RJ-45 jacks on it. (Which isn't unheard of, mind you,
but it's rare.)
There are still some things out there that care about polarity, though
you're unlikely to run into them. I found out the hard way this week
that polarity matters a lot to DID lines. Ended up making a custom
cable for a new fax modem because the jack at work was wired backwards,
to compensate for some old equipment that was also wired backwards. DID
lines are their own special nastiness, though; take everything about how
phone signalling normally works and stand it on its head, and you have a
good idea how a DID line is set up.

having no luck at dialing in on the new number I listened in while
dialing and heard the recording "you must dial a 1 and the area code"
does this meen the call is now long distance for us western washtenaw
users? If so I'm upset. It basicaly makes my other computer and my
mother's useless. Why couldn't we keep and ann arbor phone?

Leslie/arabella's .login file doesn't run when she logs in. This broke
with the migration to the new machine. The commands in the file
all seem to run fine if she types "source .login"
I can't figure out what's different between her setup and mine; my .login
has always run as expected.

How many hours a month do you normally dial in to grex from those two
computers? Access-4-free offers ten free hours/month internet access from
which you could telnet ($5 signup fee). And I ran across one long distance
phone company which was under 3 cents/minute within MI. I had no idea Ypsi
was a long distance call from Chelsea.

Is ypsi at least local for some towns that Ann Arbor is not, east of ypsi?
Steve, do you have a dsl line at your usual computer and if so, does this mean
you cannot also dial in to the isp from other locations?
I suspect another friend in Chelsea is going to drop her grex membership if
she has to pay for an ISP to reach her mail here. If the old number is
forwarding, is that original number still a local call from Chelsea? That
would at least give people 90 days of free calls while they found another way
to access mail.
I still cannot dial in to grex. Worked right after the modems were
reinstalled but not since then.

Just wondering if some protection was different somewhere in the
paths. Making the .login executable might be worth the trouble.
I have a very dim memory, of the hash mark "#" as the
first char on the first line of a script, in some cases,
for some shells, also making a difference *on the second line*.
I can't find any corroboration but it's worth a try.

I'm having a problem in that when I log in on occasion, it treats all items
in Winter like a brand new item. Is this due to rebooting or what, and how
can I fix it? Or more importantly, how much of a bribe to get a staff member
to fix it for me?

If there are enough members who need local access to grex, we might be
able to justify the expense of having some sort of call forwarding from
Ann Arbor.
