Message-ID: <CAEFFt-HjzQSM1AjzJPGwhd_Jcd7HAuQske2kPK=dFtHGP-XLUg@mail.gmail.com>

Happily running on the following computing nodes:
lov[1-6], low1, ari, Foxconn, GPU[3-14].

Athena runs some KVM guest so traditionally MATLAB was not available
there (MATLAB licensing server is adverse to virtual network
interfaces).

GPU1 is still down due to hardware problems. I am hoping to get around
fixing this week. I would like to upgrade NVidia driver and CUDA on
GPU2 before installing MATLAB. This is the only GPU node which still
has CUDA 9.1

Just a heads up. Bunch of virtual machines are down due to the fact
that the host is down. I suspect CS CMU facilities guys powered off
machines when they were replacing dead UPS batteries (which I
requested). I am working on resolving this issue.

This is covered during the orientation

/opt/rh/rh-git218/root/bin
root at lov6$ ./git --version
git version 2.18.1


The stock Red Hat git version is much older so we prefer to use the
one which comes from Scientific Computing repos. Path in your shell
configuration file need to be updated accordingly.

That version of git is pulled as a dependency for some package. That
is a stock Red Hat git version. If you look in /opt/rh you will see
another version older than 2.18 which is in itself pretty old also
compared to what people use these days. I am CC-ing again
users at autonlab.org as I think many people might be confused with this.
I hope you are not going to refer to me as a git for doing it :-)

Dear Autonians,

I am very excited to announce that Luke Sciulli whom many of us have met
already,
will be joining our team as a Senior Research Analyst/Manager on Oct 21.

He will contribute his energy and experience as a combat medic who have
been both delivering
and receiving trauma care in the field.

Luke will share the office with Trish.

Please join me in welcoming him to the Lab!

Cheers,
Artur

We had everything what's needed to properly celebrate the Auton Lab 26th

Hi All,


Thanks for coming to the picnic yesterday. Here's the list of vendors for your reference.


The food vendor is Taiwanese Bistro Cafe 33 (http://twcafe33.com/) and the cake is La Marquise from La Gourmandine (https://lagourmandinebakery.com/cakes-tartes-new/)

Thanks to everyone who participated, but special thanks go to Jessie and Nick and all others who helped prepare yet another successful picnic!
We had everything what's needed to properly celebrate the Auton Lab 26th Birthday, including even classy coffee :)

For your records, a picture of our extraordinarily trendy cake:

You are mixing swig from the base with python from miniconda3. I just
upgraded miniconda3/python to 3.7.4 on GPU8 and I installed for you
swig-3.2.1

root at gpu8$ pwd
/opt/miniconda3/bin
root at gpu8$ ./swig -version

SWIG Version 3.0.12

Compiled with x86_64-conda_cos6-linux-gnu-c++ [x86_64-conda_cos6-linux-gnu]

Dear Autonians,

This has been obvious to us for quite a while, but is nice to know we are
not alone in knowing that Maria is a (Rising) Star.

She was invited to present at the appropriately titled workshop promoting
the excellent work done by young women researchers in computer science,
computer engineering and electrical engineering:
https://publish.illinois.edu/rising-stars/

Way to go Maria!

Cheers,
Artur

PS We had some Auton Stars participating in these prestigious annual events
in the past, including Reihaneh Rabbany and Ina Fiterau, and I know we have
more in the pipeline :)

Message-ID: <CAEFFt-FfFLs9i=RK0eTdSdDK9xsQ4-JRpqGKUs6S-Fok8dW68w@mail.gmail.com>

Hi,

TLS handshake between the computing nodes and LDAP server is broken. I
noticed this a few hours after regular 6 months upgrade of our network
servers running OpenBSD. At this point I am not sure if the handshake
is broken due to expired SSL certificates (generated five years ago)
or some problems with libcrypto. We use cashing on our computing nodes
so if you have logged into them before your credentials are cached and
this will not affect you. However Gogs (git.int.autonlab.org) will not
let you log in.

I am working on q fix right now.

Hi John,

Did you receive my email this morning? LDAP server is down due to the
broken TLS handshake. I am trying to fix it. At his point I am not
sure if this happen due to expired SSL certificates or broken
libcrypto after I did regular upgrade of our OpenBSD machines. I have
the LDAP backup server but it is upgraded as well as I didn't realize
until much later in the day that upgrades breaks TLS.

Credentials are cached on computing nodes. They must have logged into
our infrastructure recently and the computing nodes didn't bother to
authenticate them against LDAP. My guess that this would be true for
most people who regularly use comp nodes. In your case server asked
LDAP and the connection was dropped. Either this is the first time you
are logging into a specific computing node or your previous loggins
are no longer cashed.

Hi Autonians,

The problem with LDAP appears to be more serious than I originally
anticipated. I have regenerated SSL certificates and TLS handshake
still fails. I am working with developers upstream to see why is this
happening. I don't want to enact nuclear option and allow your
password to be transferred in clear text between LDAP server and
computing nodes. I would much rather "downgrade" installation if
needed than take that path.

Thanks for your patience.

Ok. I have a solution for this. Namely I was at least smart enough not
to upgrade all 10 OpenBSD servers to 6.6. I left one :-) running 6.5.
It was not LDAP backup server which I also upgraded yesterday but one
of new mighty backup firewalls machines which was idling. I have fully
functional LDAP server running on it. I tested only one computing node
with new setup (lov1) and works like a charm. You will now have to
wait 2-3h until I globally push changes. I want to make sure I don't
screw up anything else before this goes into production.

Cheers,
Predrag

The changes I pushed onto the server appears to work like a charm and
LDAP is up and running. I tested it. Before anyone cries foul I would
like to warn you. Some of you have tried pretty hard to log into our
gateways. John I am thinking of you :-)


There were 62 failed login attempts since the last successful login.

That have probably ban (temporary) the IP address from which you were
trying as it was understood by the intrusion detection system as a
brute force attack. I will not start manually deleting IP addresses
from the firewall jails until tomorrow morning. Based on the severity
of the offense your IP should be OK by then. If you still can't log
into the system please send me the IP address (if it is fixed) of the
machine you have been trying from.

Finally this incident could not end up without  ritual sacrifice.
Computer Gods have requested and we have brought the lifeless body of
our legacy shell gateway lop1.autonlab.org  which have perished during
the debugging process.  If you need to access the DMZ zone from shell
gateways (Jarod I am thinking of you) please ping me. Available shell
gateways are:

bash.autonlab.org
lop2.autonlab.org

libcrypto is not fixed yet upstream and NREC as well Auton Sys LDAP
servers are for now running 6.5 version of OpenBSD.

Best,
Predrag

Fixed! I forgot to update LDAP configuration files yesterday on Gogs
and a few other places after switching to a new LDAP server. Fixing it
right now. FYI the real upstream fix for 6.6 release is coming up.

Subject: lop1 shell gateway resurrected
Message-ID: <CAEFFt-ET=XB4wP7LOnQBq9FpNZ8iFyNpUTPUb+qUT8-XDxSUGA@mail.gmail.com>

Dear Autonians,

In spite of my original assessment I was able to resurrect our third
gateway lop1.autonlab.org

ECDSA key fingerprint is SHA256:pvrXGlYOcrBOtI5b7xt4sItRkIbqRMhJ+qLRlTrgIts.
ECDSA key fingerprint is MD5:a4:16:e5:14:ce:a1:c4:7f:74:fc:28:bd:f9:81:85:69.


This is good news only for lab members who have legacy accounts (home
directory on /zfsauton). Newer account holders (home directory on
zfsauton2 or zfsauton3) are not able to use this gateway.

Best,
Predrag

P.S. Our LDAP server still runs OpenBSD 6.5 and I will not be
upgrading to 6.6 until upstreams developers and I are 100% that things
work as expected.
