Grex System Problems - Fall 2015/Winter 2016
| 
Dec 31 16:42 UTC 2015 |
This item is for system problems. If something on Grex isn't working
right (weird behavior from a program, etc.), this is the place to
announce it. Except for security holes. If you find a hole in system
security, mail information about it directly to "staff".

My browser is telling me grex is unsafe. I told it that slynne and zulu
are gone but it insisted that I proceed with caution.

Oh. We need to renew the certificate, probably.

Hi there.
It seems that grex is still using OpenBSD 5.0. That's
too old.
It would be nice to have latest OpenBSD running on
grex, maybe the next 5.9 version.

What exactly are the criteria for "too old?" Seems to be working perfectly
fine...

We've talked about this repeatedly for the last several years. Our goal
is to migrate to FreeBSD. That requires more time than staff currently
have to devote. So we are in a holding pattern and leaving what works
alone. Just updating OpenBSD to a newer version would require more
staff time than we have right now (local applications would likely need
updating). If we were to do anything we'd rather put that time toward
FreeBSD.

Ok. No problem here. Moving to FreeBSD is also
acceptable, because of simpler incremental binary
upgrades.
As long as the system is running just fine, I think
it doesnt matter how old the os.
Maybe it would be simpler to stick to the old Unix
"if it isn't broken, don't fix it"

The thing is, OpenBSD sucks and actually is kind of broken.
The system panics every now and again because of it.

Grex was inaccessible for at least a day or so (or so it seemed)
due to a UPS failure causing the server Grex exists on to reboot
and then die. This lead to the dreaded "no route to host"
message when trying to connect. The issue should be fixed now.
Thank you, Tony!

Grex was up and down a couple times starting with last Friday and into
Sunday evening. Both times it was the bug in the OpenBSD system that
caused it although it is not clear if anyone has found a way to make it
happen sooner. The load average was over 150 on Saturday before I lost
my connection. It was not clear what was causing that sort of load and
top showed a lot of 0% cpu processes.
Thanks to Tony for coming to the rescue on these issues several
times this weekend!

Grex went comatose again this afternoon/evening. Thanks to Tony for
the reboot!

Is a reboot like a smelling salt?

What happened was we lost our network connection for a while, so Grex
itself was still alive, but a reboot got it connected again after the
box that was handling the network was rebooted.

(not dead yet, just *very* busy!)
Can someone set up the reverse DNS for grex? Right now it's just the dynamic
address that SBC is handing out. Probably seems kinda nit picky, but it really
helps in e.g. IRC to see @grex.org (or @cyberspace.org, or whatever) when a
user connects.
I can set it up if staff doesn't have time and would like help.

I think we are going to have to wait for Tony to check in. Now that grex is
a virtual machine, reverse DNS may not make sense.

Reverse DNS would be a good idea.

Okay, we had another network issue and OpenBSD decided to check out of
consciousness for a while. Tony shocked it back to life again. Thank
you, Tony!

I would like to thank whoever installed Maxima on this machine. I can't
install any math software on my work computer and grex has just saved the day!

Thanks for letting us know you use it! I think I installed that a while
back. There are several such applications on Grex, including Octave,
Maxima, FreeMat, and R. I'm glad it worked for you.
An incomplete list of installed softare on Grex is available at:

Unfortunately, it's not possible to get reverse DNS for grex. :( I tried
to do it, but AT&T has a silly limitation where they will only give
reverse DNS for a single domain name. Since it's hosted here, and I have
my own stuff on my network, tonster.com trumps grex.org and
arbornet.org. :) Thus, no reverse DNS. At least, no reverse DNS that
makes any real sense.
In other news, I just finally managed to get the SSL certificate
replaced. No more warnings about how dangerous grex.org is, though I'm
still not convinced that's a good thing. :)
