iproute2mac

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

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) [Preferred] Using Homebrew:

# [Optional] Install Homebrew first, see http://brew.sh for options
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install iproute2mac
$ brew install iproute2mac

B) Manual installation from HEAD:

$ sudo mkdir /usr/local/iproute2mac
$ sudo chown -R $(whoami):admin /usr/local/iproute2mac
$ cd /usr/local/
$ git clone https://github.com/brona/iproute2mac.git
$ ln -s iproute2mac/src/ip.py /usr/local/bin/ip
$ ln -s iproute2mac/src/bridge.py /usr/local/bin/bridge

Supported commands / Example usage

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