That is unfortunately only too true, as recent events will attest.
And it's a pity.

I have told everyone to send me important mail at sdf. But I can still use
grex to access sdf, when grex is working.

Please put a date on the motd. 'Grex was down much of today' is outdated.
Can motd messages be written to automatically expire?

Sindi, there was a current date at the top of the message when I
logged the down message and the date was further updated when I
logged the "the back up" message a few hours later.
It should be fairly easy to write up a script that can be run by
grex itself at boot time or out of cron every so often which would
update the status and update the time stamp.
The script could also log a warning to the effect that any status
who's last update date was more than X hours may imply that grex
is down. If the system was up but /etc/nologin existed, the status
message would include the text of /etc/nologin. Status could
otherwise be manually updated as now by staff working on the problem,
and the system would automatically overridden that when it rebooted.

I did not see any date when I ssh'ed to grex and read the motd, or when I just
typed !motd now and read it again. Or did you not mean the motd displays a
date? I suggested that instead of writing 'today' you write 'today, Dec. 20'
Or 'Tuesday, Dec. 20'.

I knew I should have finished my morning coffee before conferencing
this morning (today, December 19 JST)
My brain substituted hvcn status page where you mentioned motd in
#260. Sorry.

Re resp:258: How things have changed. Once upon a time my Grex email
was more reliable than any of my college or ISP accounts. That was back
before we switched to OpenBSD, though, which has proved to be
considerably less stable than SunOS. That kind of surprises me, since
I've run FreeBSD servers for a long time without many problems.

Quite possibly. It's still surprising, because they share a lot of code
(in both directions.) I haven't used OpenBSD for much except
stand-alone firewalls, though, so I have little personal experience with it.

Maybe that's why OpenBSD is ranked so secure. I defy anyone to break into a
system that's off.

I have a USB to IDE controller I use to break into systems that are "off".

Gull, unless you are referring to something else, the only email
unreliability problem I recall since the upgrade was caused by human
error, not any kind of system problem.
If you are talking about other instabilities, most of those are our
own fault, having procrastinated on upgrading from 3.5 to 3.8,
excepting the possible memory or motherboard problem staff are still
tracking down.

Mail sent to grex via an earthlink account is bouncing because they got tired
of retrying. Mail sent via this same account is being 'DENIED' by some other
place to which I can send mail from grex. SMTP error. Freeshell was
blacklisted for a while last week. I am really grateful that I can send mail
from grex to anywhere, but why is incoming mail timing out?

Just today, when I first used this account. Just now I tried sending to grex
from earthlink/mindspring, wcc, and one other account. The first two mails
arrived immediately and the last one is not here yet. I first looked up the
popmail server name. It is not returned yet either.
What bothers me is that mail sent via earthlink was 'denied' by someone else
I was sending to. Grex mail gets through all the time unless we are on the
RBL blacklist, which has not happened recently.

I probably sent the third mail wrong. Another attempt came immediately.
Grex must have been busy with a lot of ingoing or outgoing spam at around 3:29
this afternoon.
