Ethernet OverView (ethov)

ethov is a simple Bash-based tool for providing an overview of network interfaces in Linux. It provides detailed information about physical and virtual network interfaces, including the interface's speed, link status, card name, and additional details such as IP address, MAC address, MTU, and supported speeds.

Features:

• Physical Interface Info: Shows detailed information about network interfaces, including card name, MAC address, MTU, IP address, and available speeds.
• Virtual Interfaces (Bridges / Bonds): Provides detailed information on virtual interfaces, including the member interfaces and their speeds.
• Link Status: Displays the current link status (Up/Down) with a color-coded dot icon (🟢/🔴).
• Speed Information: Displays available speeds for interfaces and determines the speed for active members of bonds and bridges.
• Color-Coded Output: Different network speeds are color-coded for easy identification.

📋 Requirements

For ethov to work correctly, the following tools must be installed and available in your system:

Command	Package Name	Purpose
lshw	lshw	Retrieves hardware information (e.g., card name)
ethtool	ethtool	Gathers interface speed, link status, etc.
ip	iproute2 (usually preinstalled)	Gets IP addresses and interface info
awk	gawk or mawk (usually preinstalled)	Text processing
grep	grep (usually preinstalled)	Pattern matching
cat, ls	coreutils	Basic shell utilities

✅ On most Debian/Ubuntu/Proxmox systems, only lshw and ethtool might need to be installed manually.

Get the script localy:

1. Clone the repository to your local machine:

   git clone https://github.com/Micinek/ethov.git
   cd ethov
   

2. Make the script executable:

   chmod +x ethov.sh
   

3. Run the script:

   ./ethov.sh
   

Running the script localy:

Simply run the script to see an overview of all network interfaces on your system:

./ethov.sh

Running the script directly from GithubRepo:

Simply run the script to see an overview of all network interfaces on your system:

bash <(curl -s https://raw.githubusercontent.com/Micinek/ethov/refs/heads/main/ethov.sh)

The script will display information for each network interface, including:

• MAC Address
• MTU
• IP Address (IPv4)
• Link Status (Up/Down)
• Speed
• Supported Speeds for physical interfaces
• Member interfaces for bridges and bonds
