Dropbear is a Linksys WRT54GL wifi router running OpenWrt.

Overview

Dropbear is a Linksys WRT54GL wifi router running OpenWrt. The hardware is pretty slow (200 MHz processor) and the on-board storage is only about 20 megabytes, so it's pretty limited in terms of baked-in capabilities. There is also no USB port or expansion slot.

Some of these shortcomings can be overcome through hardware hacking - soldering an external USB port to the board inside, for example, to use external USB storage - but I did not need these modifications for my purposes.

Plus, Widy is the same cost, easier, battery-powered, pocket-sized, and takes USB. What's not to like about Widy?

Listing Installed Packages

Create a temporary script:

vi /tmp/listuserpackages.sh

with the following contents:

#!/bin/ash
echo >&2 User-installed packages are the following:
sed -ne '/^Package:[[:blank:]]*/ {
	s///
	h
}
/user installed/ {
	g
	p
}' /usr/lib/opkg/status

This will print the name of all packages installed:

This OpenWrt wiki page on the WRT 54GL was very useful: https://wiki.openwrt.org/toh/linksys/wrt54g

side note:

This discussion on Github seems to indicate there is a netdata package available via opkg: https://github.com/firehol/netdata/issues/385

However, this was not the case using opkg 0.1.8 on Barrier Breaker. Then again, this OpenWrt/opkg is a couple of years old now.

The packages released for FireHOL provide a Chaos Calmer version, and instructions for pre-Chaos versions of OpenWrt have disappeared: https://github.com/firehol/packages/releases/tag/2017-10-14-1440

This page gives instructions on how to install the .ipk file: https://firehol.org/installing/openwrt/
