Multiport | Multiport is a port scanning utility designed in Python

I am working in a program that autosaves MIDI messages as they are played, and everything is working really well when using a single input port. I want to extend to use 2 or 3 simultaneous ports (the app is aimed at VST piano players, and some use the piano as one MIDI device, and the sustain pedal as a second device in another USB slot). I was able to get it to work using two separate input ports, and then using 2 iter_pending() loops. The basic code is something like this:

Have set up fail2ban service on CentOS 8 by this tutorial: https://www.cyberciti.biz/faq/how-to-protect-ssh-with-fail2ban-on-centos-8/.

I have set up settings similiarly according to tutorial above like this:

I am looking to a way to leverage null coalescing feature that exists in other language for my script but I can't seem to wrap my expression to accept the first non null value from an expression and a variable in a one line .

Context

I need to check the list of specific inbound open ports from my azure network security group but there are two sources where ports can be defined (all port in one rule [22,80,etc} or one port per rule [rule1=22 , rule2=80 etc])

To make this simple :

I have two variables and they store list of ports in a vertically (Array).how I get the values doesn't matter

• $nsg_port_a (ports found on multiport rules)
• $nsg_port_b (ports found on all single port based rules)

All:

I'm attempting to configure nginx to reverse proxy requests from (192.168.0.2:12345) the same Internal Host Address that it's listening from (192.168.0.2:443) on separate ports using the listen and proxy_bind directives.

I posted a question similar to this and tried to implement what the answer for this question said: How to access Kubernetes container environment variables from Next.js application?

However, when I still call my environment variables doing process.env.USERNAME, I'm still getting undefined back... Am I doing something wrong in my deployment file? Here is a copy of my deployment.yaml:

In a time series dataset, what would be a good way to group sets of rows such that they have a unique identifier in a new column? For instance (in a very abridged manner), taking this:

Recently, my manager installed fail2ban on our ubuntu 10.04 email server to ban ip addresses that failed to authenticate to our email server. As we monitor the system, we don't see the IPs that continually try to authenticate on our system banned by fail2ban. What are we doing wrong? Below are the conf files:
