This response is made by sshing from my machine to oldGrex and then from
oldGrex to Grex. So it passes over the old, flakey DSL twice. It is, as
should be expected, quite slow. A good way to learn patience. :)

As if we have not had enough practice with patience in the past couple of
months! Telnet is not bad now.

Are there plans to move the dialin lines to the colo site, or will they
be dropped when the lease expires on the Pumpkin?

I'll be faxing the information to transfer the lines to the telephone company
later today. I am sorry that this has taken so long. :(

From one who is "spoiled" by SiteScope in the workplace: Is there enough
spare grex hardware lying around to construct a "monitor" box whose sole
purpose would be to monitor grex and when it detects something irregular (such
as no response within a reasonable period) to notify whomever it would be
willing to be so notified?

My arrow keys still do not work in fronttalk with my 84-key keyboard (or
probably with the 101-key keyboard either). Yes it said Fronttalk (it
scrolled by too quickly to read anything else) when I typed ft and I do not
have a scroll buffer in linux except in vga and I am using mda.

I see robocop is running now. Or was running. Things just speeded up.

When scribbling a recent response that wasn't very interesting:
Respond, pass, forget, quit? scribble 23
Segmentation fault
grex%
I've got "limit coredumpsize 0" set in my .tcshrc, so no core file
(not that anyone would have time to track it down..) Is there a
problem with the perms on the censored log, perhaps?

Grex ssh worked last night but this morning: remote host failed or
refused to allocate a pseudo tty. (A bunch more lines and then a
blinking cursor).

Now I could ssh and login but then 'unable to find your tty (ttyr4) in utmp
file. Things seem to be working okay anyway.

Lynx is working, ridiculously fast! I keep overshooting. But ftp (for
members) is not working with lynx.

I don't find it too surprising that ftp doesn't work within lynx; lynx isn't
linked to the necessary wrapper.

When I ssh here 'unable to find your tty in utmp' again but it works.
Ftp has not been working in the browsers for a while now and I hope it can
be fixed soon so that I will not have to exit lynx to use ftp once I find the
directory I am interested in getting a file from - last night it was a modem
upgrade file from usr that I could not access on my own slower connection (it
took so long that lynx on my computer started to look for www.usr.com.edu).
I can ftp between my computer and grex now.

I mention this because I don't know whether something was done since the last
mention (but if it was, it didn't work):
I just got
mesg: Unable to find your tty (ttyq6) in utmp file
when logging in.

Sindi slipped in, with probably the same problem (with mesg).

Just as another data point, I'm still receiving the type of error when
ssh'ing into grex that is described in resp:614 and others, above. Here
is the oddly formatted text that is written to the screen when this happens:
<pasted>
Server refused to allocate pty
Warning: no access to tty (Bad file descriptor).
Thus no job control in
this shell.
stty: mesg: I/O stream 2 improperly redirected
not a terminal
stty: not
a terminal
tset: standard error: Inappropriate ioctl for device
stty: not a terminal
mesg: I/O stream 2 improperly redirected
watch: Could not identify your terminal
</paste>
Note: this error doesn't always happen but when it does it seems
impossible to ssh at all.
I would appreciate any explanation as to why this occurs, still. On the
old Grex server, this would happen a lot and everytime someone asked,
we'd get the pat explanation that "just wait until next Grex; all these
problems will go away."
Thank you for your attention to this matter, volunteers.

I thought he mentioned it somewhere above, but perhaps folks missed it:
OpenBSD doesn't write information to the utmp file as quickly as it could.
So things that look at utmp, like mesg, during login sometimes fail. So
Jan added a one-second retry to mesg. Sometimes, even that one second isn't
enough.
Personally, I've taken to running the mesg command from my .login by hand when
I see that message, figuring that by the time I can enter commands by hand
utmp has been updated.
On oldGrex, the "failure to allocate pty" error was caused by the telnet
queue. NewGrex doesn't have the telnet queue, so we didn't expect to have
the "failure to allocate pty" error. However, sometimes no ptys are
available, with the result reported in #621 above and elsewhere.
Right now, we don't know why ptys aren't available. We have tried increasing
the number. We've not stopped investigating the problem.

This would be a really low priority item compared to all of the rest,
but is there any chance of upping the time limit you are given to
authenticate before ssh times out? The old grex used to be quite
generous in this regard, now I find that if I start ssh and switch
to another window I often run into the limit before switching back.

Any progress on moving over the modems? We know at least one grexer with no
other way to reach his mail, and he assumes it is now full of spam and
bouncing all his real mail.

Well, let's see . . . Three modems (one a spare) are now at Provide.Net.
One is attached to grex. The other needs a different cable, because there
wasn't enough space for two DB25-DB9 adapters on grex's serial ports.
I borrowed a telephone cord from the Provide.Net people, to connect that modem
to the telco. (Amazingly, it hasn't been called yet. :)
I think we need to turn on the tty for the connected modem. I also think it
is on tty00. Unless I guessed wrong, in which case it is on tty01. I don't
know yet if turning it on will require a reboot. Whether it does or no, I'm
going to turn on both at the same time.
Before my next visit to Provide.Net, I need to get:
two 25-foot telephone cords
A DB9-DB9 serial cable, preferrably male-female.
The last could be replaced by a DB9F-DB25M serial cable.
BTW, a serial-to-USB adapter at Radio Shack was $41.xx, just a little more
than a new, external USB modem.
