iproute2mac

CLI wrapper for basic network utilities on Mac OS X inspired with iproute2 on Linux systems - ip command.

Provided functionality is limited and command output is not fully compatible with iproute2.

Goal of this project is to make basic network configuration/debug tasks on Mac OS X easy for admins who already use Linux systems.

For advanced usage use netstat, ifconfig, ndp, arp, route and networksetup directly.

Installation

A) Using Homebrew:

# [Optional] Install Homebrew first - see http://brew.sh for more options
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Install iproute2mac
$ brew install iproute2mac

B) Manual installation:

$ curl --remote-name -L https://github.com/brona/iproute2mac/raw/master/src/ip.py
$ chmod +x ip.py
$ mv ip.py /usr/local/bin/ip

Supported commands / Example usage

Goal of this utility is to provide compatible CLI with iproute2, supporting same command shortcuts and user experience.
