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
