polybar-interface-switch

This polybar module shows the IP address of a specific network interface. Also allows you to change the selected interface with right-click and copy the IP address to the clipboard with left-click. It's very useful in CTF games when you have to constantly copy your IP address for a reverse shell.

Usage

• Left Click: Copy the IPv4 address of the previously selected network interface.
• Right Click: Launch Rofi menu to select a new network interface.

Dependencies

• iproute2: To list the available network interfaces and their associated IP addresses.

 # If for an incredible reason you don't have this indispensable network tool installed
 $ apt install iproute2 -y

• xclip: To copy the IP address to clipboard.

 # Install xclip from apt
 $ apt install xclip -y

Setup

• Make sure to go through the config variables in interface_switch.sh, copy_ip.sh and show_ip.sh. They should be pointing to their corresponding configuration files.

# interface_switch.sh
SDIR="$HOME/.config/polybar/scripts"
CONFIG_FILE="$SDIR/interface.conf"    # Store the selected network interface
STYLES_FILE="$SDIR/interface.rasi"    # Styles for rofi menu

# copy_ip.sh
CONFIG_FILE="$HOME/.config/polybar/scripts/interface.conf"

# show_ip.sh
CONFIG_FILE="$HOME/.config/polybar/scripts/interface.conf"

• Add the following code in your polybar config.

[module/interface_switch]
type = custom/script

format-background = ${color.alt-bg}
format-foreground = ${color.green}
format-padding = 2

interval = 90
exec = ~/.config/polybar/scripts/show_ip.sh
click-left = ~/.config/polybar/scripts/copy_ip.sh &
click-right = ~/.config/polybar/scripts/interface_switch.sh &
