Update Manager

Lightweight SSH-based update manager for Linux systems.

Features

Check for updates across multiple hosts
SSH-based (no agents)
Simple host inventory
No external dependencies

Installation

git clone cd update-manager chmod +x update-manager.sh ./update-manager.sh install

This will:

Install the tool in /opt/update-manager
Create global command: update-manager
Create config files if missing

Configuration

Edit hosts:

nano /opt/update-manager/hosts.conf

Format:

name ip ssh_user

Example:

server1 192.168.1.10 user server2 192.168.1.20 user

SSH (required)

Passwordless SSH must be configured.

ssh-keygen -t ed25519 ssh-copy-id user@192.168.1.10

Repeat for all hosts.

Test:

ssh user@192.168.1.10

Should work without password.

Usage

update-manager check

Output

server1 🔴 2 updates server2 🟢 up-to-date server3 ❌ connection failed

Config

/etc/update-manager.conf

Default:

HOSTS_FILE="/opt/update-manager/hosts.conf" SSH_OPTIONS="-o BatchMode=yes -o ConnectTimeout=5"

Notes

hosts.conf and update-manager.conf are local files (not in Git)
.example files are templates
Existing config is not overwritten on reinstall

Roadmap

update command
parallel execution
scheduled checks
logging integration

Philosophy

Keep it simple.

No agents
No dependencies
Just SSH
