R host requests machine to get a license message - r

When I run my R script I get this message:
20141118161918 INFO: 'snx1app011:40001' host requests to '10.61.24.59' machine to get a license
Have you see that and do you know what it means?
Thank you,

Maxscale: maxctrl error when admin_ssl parameters are set in maxscale.cnf

System:
Maxscale 2.5.9
Ubuntu 20.04
In order to access the Web AdminGUI my maxsclale.cnf file looks like this:
[maxscale]
threads=auto
admin_host=0.0.0.0
admin_secure_gui=1
admin_auth=1
admin_enabled=1
admin_gui=1
admin_ssl_key=/etc/ssl/certs/maxscale-key.pem
admin_ssl_cert=/etc/ssl/certs/maxscale-cert.pem
admin_ssl_ca_cert=/etc/ssl/certs/ca-certificates.crt
[...all other configuration..]
With this configuration I can access the Web-AdminGUI on port 8989 from the internal ip address (not 127.0.0.1) by browser.
The SSL key/certs are self-signed .
BUT
When using the command line like:
maxctrl list servers
I get the following error:
Error: Error: socket hang up
When I remove or comment out the lines with the admin_ssl_XXX parameters and restart maxscale, command line works again, but of course the Web-AdminGUI does not.
I tried with various SSL certificate creations (also the one that is listed on the mariadb.com-Website
https://mariadb.com/docs/security/encryption/in-transit/create-self-signed-certificates-keys-openssl/#create-self-signed-certificates-keys-openssl),
the issue remains.
No errors in the maxscale.log whatsoever.
What is the best way to debug this issue?
Or do you have by any chance the right answer at hand?
YOUR help is greatly appreciated!

You should use maxctrl --secure to encrypt the connections used by it.
Since you are using self-signed certificates, you have to also specify the CA certificate with --tls-ca-cert=/etc/ssl/certs/ca-certificates.crt if it's not installed in the system certificate store.
In addition, you probably need to use --tls-verify-server-cert=false to disable any warnings about self-signed certificates.

Hiveserver2: could not start ThriftHttpCliService

I'm attempting to enable SSL on hiveserver2.
I can run in the default binary mode fine. http mode works no problem. As soon as I enable SSL through hive-site.xml, i'm faced with the following error.
ERROR [Thread-28] thrift.ThriftCLIService: Error starting HiveServer2: could not start ThriftHttpCLIService
java.net.BindException: Address already in use
There is nothing using any of the ports, prior to starting hiveserver2. Checked with netstat -tupln
Ports i've configured in hive-site.xml are
hive.server2.webui.port 11002
hive.server2.thrift.http.port 11001
hive.server2.thrift.port 11000
and invoking hiveserver2 via the service /opt/hive/bin/hive --service hiveserver2 &
O/S ubuntu (on kubernetes)
Hive version 3.0.0
Any help greatly appreciate. Google search for problems with ThriftHTTPCliService came up short.
For anyone that come across this post.
I upgraded to Hive 3.1.0, along with the metastore schema.
This fixed the issue, although unsure as to the underlying cause.

MPI A process or daemon was unable to complete a TCP connection

Open MPI: 4.0.1a
HostFile:
34bb0519eAAA
a2935f150BBB
I am in machine 34bb0519eAAA. And I could use ssh a2935f150BBB to connect a2935f150BBB successfully. And also ssh 34bb0519eAAA In machine a2935f150BBB to connect 34bb0519eAAA successfully .
But when I mpiexec command . I get error message
****Warning: Permanently added '[XX.XX.XX.XX]:XX' (a2935f150BBB'IP address) to the list of known hosts.**
----------------------**--------------------------------------
A process or daemon was unable to complete a TCP connection
to another process:
Local host: a2935f150BBB
Remote host: 34bb0519eAAA
This is usually caused by a firewall on the remote host. Please
check that any firewall (e.g., iptables) has been disabled and
ORTE was unable to reliably start one or more daemons.
This usually is caused by:
* not finding the required libraries and/or binaries on
one or more nodes. Please check your PATH and LD_LIBRARY_PATH
settings, or configure OMPI with --enable-orterun-prefix-by-default
* lack of authority to execute on one or more specified nodes.
Please verify your allocation and authorities.
* the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base).
Please check with your sys admin to determine the correct location to use.
* compilation of the orted with dynamic libraries when static are required
(e.g., on Cray). Please check your configure cmd line and consider using
one of the contrib/platform definitions for your system type.
* an inability to create a connection back to mpirun due to a
lack of common network interfaces and/or no route found between
them. Please check network connectivity (including firewalls
and network routing requirements).
I am very confused that.Because I run ssh to each other successfully . How could fail that.
Here is ssh connection
ssh a2935f150BBB

Unable to reach Sentry log server: EOF occurred in violation of protocol

I'm having trouble with setting up Sentry server in HTTPS mode. Every now and then, reasonably often while seemingly random, this error message gets written by Raven (Sentry client) into log files:
Unable to reach Sentry log server: <urlopen error [Errno 8] _ssl.c:504: EOF occurred in violation of protocol> (url: https://$(valid_server)/)
Web UI works fine. Vast majority of the messages from Raven are received fine and Sentry processes them into usable output. However, due to these errors, something gets lost from time to time.
I have tried to figure this one out, but dead ends seem to follow another. Basically it seems a lot like this:
Python Requests requests.exceptions.SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
But when testing my Sentry server with similar s_client query using TLS 1.2, it leads to a valid session unlike with the example there.
It's also not about this, since SNI isn't used:
python-requests 2.0.0 - [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
I'm not able to reproduce the error coherently. Raven's tests are passed and nothing is acutely wrong, until an error pops up in the log.
My set up is: Raven 4.2.1 in Python 2.7.5, Nginx 1.6.0 as reverse proxy handling HTTPS, and finally Sentry 6.4.4 with default Gunicorn 0.17.4. Nginx configs are pretty much similar to official documentation (http://sentry.readthedocs.org/en/latest/quickstart/nginx.html) with a few alterations due to HTTPS.
I ran into the same issue and got it fixed by installing the following dependencies:
On Ubuntu:
sudo aptitude install libffi-dev
And then via pip:
pip install pyopenssl ndg-httpsclient pyasn1
The problem seems to be that Python 2.X doesn't support SNI (which is needed for TLS) out of the box as explained here.

Arch Linux on VirtualBox network problems

I've installed ArchLinux with VB on MacOS. I have network problems, I cannot resolve addresses. When trying pacman -S htop for example I get the following error :
:: Retrieving packages from extra...
error: failed retrieving file 'htop-1.0-1-x86_64.pkg.tar.xz' from mir1.archlinux.fr : Could not resolve host: mir1.archlinux.fr; Name or service not known
warning: failed to retrieve some files from extra
error: failed to commit transaction (download library error)
Errors occurred, no packages were upgraded.
If I ping mir1.archlinux.fr I get a response. I'm running Network in Nat Mode.
PS: If I run In Bridge Mode I have no problems.
Can someone help me fixing this problem?
Nevermind... disabling ipv6 fixed the problem.!
Check your /etc/resolve.conf or even change for opendns/google DNS.
Then check any domain like:
dig http://stackoverflow.com
finally:
pacman -Syu
