How to access your server anywhere without SSH.

Use cases

You want to have temporary access of your server from a remote location
You don't want to authorize a key to connect via ssh

OK now lets get into the process.

Prerequisites

root access
A Linux machine with ports 3023, 3024, 3025, and 443 open
A registered domain name
An SSH client like OpenSSH.
2FA App

Download and installing Teleport

visit Teleport website

Click getting started, and select the community edition

Select acconding your platform, for me its Ubuntu 18.04 LTS, so I select the Linux 64-bit DEB version 8.0

Now login to your server via ssh, and download teleport using wget by running wget https://get.gravitational.com/teleport_8.0.0_amd64.deb

Install the deb package by sudo apt install ./teleport_8.0.0_amd64.deb

Configure your domain for SSL certificate

sudo teleport configure --acme --acme-email=your-email@example.com --cluster-name=tele.example.com -o /etc/teleport.yaml

Note if you already have reverse proxy servers running at port `443` you needed to edit it and change the port (/etc/teleport.yaml) [Included at last step].

Now start the teleport sudo systemctl start teleport.service
Add user with

tctl users add teleport-admin --roles=editor,access --logins=root,ubuntu,ec2-user

It will give you a url to access the teleport
Follow the steps in the webpage to activate

For users with port address being used by other process

Open the config file in /etc/teleport.yaml
Go to the line where

web_listen_addr: 0.0.0.0:443
public_addr: tele.example.com:443

Change the port address there
reload teleport service by sudo systemctl restart teleport.service

How to run or host WordPress with Caddy2 server

Magesh Babu — Mon, 05 Jul 2021 14:41:23 +0000

PHP Version       : 8.0
WordPress version : 5.7.2
Caddy version     : v2.4.3

Installing Dependencies

To install WordPress, you must required to have PHP and MySQL or mariaDB

Installing PHP

This is for Ubuntu/Debian Distro.

sudo apt update
sudo apt install php php-cli php-fpm php-json php-common php-mysql php-zip php-gd php-mbstring php-curl php-xml php-pear php-bcmath
If the above command returns package not found or similar error do this step else go to next step, then you need to add the PPA, you can add them by sudo add-apt-repository ppa:ondrej/php;sudo apt update and now repeat the above step
Now remove the apache2 server which is installed when installing PHP, by sudo apt purge apache2*
Check the PHP Version by running php -v

Installing MYSQL Database

If you don't have MYSQL installed refer this blog by digitalocean

Downloading Wordpress

Navigate to the required directory, where do you want to save wordpress. here I use /home/illuminate/php_sites
Download the latest Wordpress by wget https://wordpress.org/latest.tar.gz
extract the tar file by tar -xzvf latest.tar.gz
Delete the tar file after extraction completed
go to the wordpress/ by cd wordpress

Creating DB for Wordpress

If you have successfully installed mysql, create a seperate user and db for wordpress
Login to mysql by mysql -u adminusername -p and now Enter the password
replace the databasename with the database name you want.

CREATE DATABASE databasename;
use databasename;
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'@'localhost';
flush privileges;

After the above steps successful, exit the mysql by pressing ctrl+d

Editing the Caddyfile

Now add the entry to serve Wordpress

example.com {
    root * /home/illuminate/php_sites/wordpress
    php_fastcgi unix//run/php/php8.0-fpm.sock
    file_server
    encode gzip

    @disallowed {
        path /xmlrpc.php
        path *.sql
        path /wp-content/uploads/*.php
    }

    rewrite @disallowed '/index.php'
}

Now reload the caddy server.
and its done.

Configuring Wordpress

When you visit the domain configured in caddyfile, it will ask to configure if not configured.
Enter the database credentials as we created.
If it fails to write wp-config.php file, then copy the configuration from web
create a wp-config.php file inside the directory where wp-content, wp-admin, wp-content are present, for me its /home/illuminate/php_sites/wordpress
paste the contents copied into the file, save and begin the installation.

How to Sign Commits in Git for Fish Shell

Magesh Babu — Mon, 28 Dec 2020 21:04:08 +0000

Hi there 👋!

Prerequisite:

GPG Installed
Git Installed

Fish Shell

Generating GPG Key

gpg --full-gen-key

After generation of your GPG Key, run gpg --list-secret-keys --keyid-format LONG to list your GPG Keys

Now Copy The ID like this

Tell Git about your signing Key, make sure that you have configured git name and email

git config --global user.signingkey ED267DF4249ACCC3

git config --global gpg.program (which gpg)

git config --global commit.gpgsign true

Here ED267DF4249ACCC3 is my GPG key ID, replace it with yours.

Now set The value of GPG_TTY value.

set -gx GPG_TTY (tty)

Add the above line to your config.fish file which is located in $HOME/.config/fish/config.fish
Now let us test if our GPG works by running

echo "hello" | gpg --clearsign

If it prompts password for using your GPG key (if any) and generates a sign like above, then your GPG Sign is configured successfully to sign commits
To sign a commit git commit -S -m "your message"

-You can check for Sign by running git log --show-signature -1

To get verified, you must add your GPG Key to your github account.
Export the GPG Public by running gpg --armor --export ED267DF4249ACCC3 remember to replace ED267DF4249ACCC3
with your own.

Visit GitHub, login and click your profile icon, select settings

In the user settings sidebar, click SSH and GPG keys.

Select SSH And GPG Keys
Click the add GPG key button

Paste the GPG that we have copied.
Click the add GPG Key button.
Now your commits that are signed with it are shown as verified in GitHub 😃
