🦑👥 Add, remove and grant sudo rights to Arch Linux users:

1) How to add, remove and grant sudo rights to users on Arch Linux
Make sure you have installed the sudo package by running the following commands as root:

# pacman -Syu
# pacman -S sudo

2) The first command will sync the repositories and update your Arch Linux system to the latest version available.
The second command will install sudo if not already installed.

🦑Then create a new user and add sudo rights to it.

1) / Create a sudo user on Arch Linux.
Run the following command to create a new user, for example undercode:

# useradd --create-home undercode
2) Set a password for the new user:

# passwd undercode
3) We have created a new user named undercode.

We haven't given the user sudo rights yet.

4) You can check if a user is a sudo user or not using the command:

# sudo -lU undercode
Output example:

5) User undercode is not allowed to run sudo on archlinux.
Yes, the user is not yet allowed to perform administrative tasks.

Let's go ahead and give it sudo rights.

To add a regular user to the sudoers list, simply add him to the wheel group.

6) For those of you curious, wheel is a special group on some Unix-like operating systems.

All members to this group are allowed to perform administrative tasks.

The Wheel group is similar to the sudo group on Debian based systems.

We can add users to the sudoers list in two ways.

7) 4The first way is to use the usermod command.

1.1. Add users to the sudoers list using the usermod command on Arch Linux
To add a user to the sudoers list on Arch Linux, run:

# usermod -aG wheel undercode
or

# usermod --append --groups wheel undercode

The above command will add a user named undercode to the "wheel" group.

As mentioned, members of the wheel group can perform administrative tasks using the sudo command.

Then edit the / etc / sudoers file with the command:

# visudo
Find and uncomment the following line (just remove the # at the beginning of the line):

%wheel ALL=(ALL) ALL
Press ESC and type: wq to save the file and exit.

You can also add the user to the sudo group:

# usermod -aG sudo undercode
Edit the / etc / sudoers file:
# visudo
Uncomment the following line:

%sudo ALL=(ALL) ALL
Save the file and exit.

We have added the user undercode to the sudoers list.

Now go to section “1.3. Let's check if the user has sudo access on Arch Linux ”and check if the user has sudo rights.

🦑 Allow Connection from Outside Local Network to your linux :

Setting up the MOSQUITTO MQTT Server in Ubuntu 18.04 is actually not hard, but the steps are important.

Step 1: Install Mosquitto Software

sudo apt-add-repository ppa:mosquitto-dev/mosquitto-ppa
sudo apt-get update
sudo apt-get install mosquitto

Step 2: Open Port 1883 and start firewall

sudo ufw allow 1883 
sudo ufw enable

Step 3: Verify Mosquitto is not already running

pgrep mosquitto
[Note, if any number shows, that is the PID of an already running Mosquitto. You can just kill it. Also, you can try: sudo service mosquitto stop]

Step 4: Start Mosquitto with verbose option

mosquitto -v
[Note: This starts Mosquitto without using any config file. It echos connection and status information to the screen. Easiest for quick debugging.]

Step 5: Check connectivity using local host

Go to your client machine (in my case a Windows 10 laptop) and run the MQTT client, connecting to the local address of the Linux Mosquitto server (in my case 192.168.0.144). You should be able to connect. In fact, you can do this step before you even open the firewall, since this is all on the local network, the firewall rules are irrelevant at this point. Until next step which is...

Step 6: Check Connectivity using web tool

use either: www.yougetsignal.com/tools/open-ports/ or https://canyouseeme.org/

[NOTE: You will not get an OPEN state UNLESS THE MOSQUITTO BROKER IS RUNNING]

Step 7: If Port Shows Closed When coming In from Internet (ie not localhost)

Here's where I got tripped up. In my case, I have a Verizon Modem that ALSO has a firewall (because it has a router). I have my own wireless router, a tp-link Archer C1200, that I have plugged into the Fios Modem/Router. I started by putting the port forwarding in the tp-link. But that firewall comes after the Fios firewall so I needed to go to the first wall and do the port forward there.

And this is the second thing that is tricky. All of the online how-to's said I should forward port 1883 to the local IP address of my Linux Server, which in my case was 192.168.0.144. But that was not correct in my case. The Archer C1200 was actually the device that I needed to forward to -- it handled the correct distribution from there. It had an address of 192.168.0.152 assigned to it from the Verizon router. I still have both forwardings in place (ie the Fios and the tp-link) and my guess is that I need them both.

🦑Just a important tip:
Many programming languages ​​support string manipulation using regular expressions :

For example, a powerful regular expression engine is built in Perl. The concept of regular expressions was first popularized by tools in Unix (such as sed and grep). Regular expressions are usually abbreviated as "regex". The singular includes regexp and regex, and the plural includes regexps, regexes, and regexen.

Front-end development, will inevitably encounter label needs to match the needs of simple needs, not just two angle brackets wrap a label name Well, the next meal operation, /<[\w]+>.*<\/[\w]+>/gand perfectly matched <div>xx</div>and so on, the demand for complete ...

Etc., first glance, it does currently can match a variety of labels, but it also can match similar <div>xx</p>content. This means that we need to keep the content in the two angle brackets the same.

Regular grouping back-reference grouping ()

The so-called grouping is to put the content to be matched in brackets (). The content in parentheses can be regarded as a whole sub-expression


/<([\w]+)>.*<\/([\w]+)>/g
Back reference \N

Regular expressions also provide a mechanism for referencing previous matching groups. Sometimes, we may find a submatch, which will reappear next.

var reg = /<([\w]+)>.*<\/\1>/
