Getting Started

In order to allow Tech Stack support team access your server, you’ll need to do some homework and take a few steps.

Public IP address for your server

We will need to have a public IP address or fully qualified domain name for your server to use, so please arrange for this if you haven’t done so already.

We will be reaching you from one of the servers that resolves back to techstack.ie domain name.

Confirm your server is backed up

This isn’t a requirement for our setup arrangement to become active, but perhaps is one of the first few steps you should be taking when putting any server online. Please make sure you have regular backups arranged for your server.

Again, if you don’t have this at the moment, we’ll be glad to assist with automating basic local (alternative disk/NFS mount) or remote (Amazon Glacier/S3 or any remote Linux server that you have access to) backups for your server.

Create a user for Tech Stack support

Please create a user called “techstack” on your server. It should be a standard user which we’ll access via SSH public key. When creating password, please use a secure combination of mixed case letters and digits. Use the https://pwpush.com service to share a password.

Secure Shell access

SSH access port

We use Secure Shell protocol (SSH) for securely accessing remote servers. By default it uses TCP port 22, but your server probably has it changed for better security (if it hasn’t, we’ll help you change this among the first tasks we do on your server).

Privileged user (root)

We usually provide your technical team with two SSH public keys, one for a privileged (root) access and another one for a regular user access.

Once you receive the public key for a privileged user, please add it to the authorized_keys file of the root user on your server.

If your security does not allow remote root access via SSH (not the best of the security practices, let’s face it), next best thing would be to provide our team with a password and sudo access to become root.

Non-privileged user (regular)

This is a key for non-privileged access. Just add this public SSH key to the authorized_keys file for the “techstack” user you should have created for our team by now.
