But it is also possible to run on ordinary computers (e.g. OpenWrt can be run on CPE routers, residential gateways, smartphones (e.g. OpenWrt can be configured using the command-line interface of BusyBox ash, or the web interface LuCI.
Install tcpdump dd wrt install#
It comprises a set of about 2000 software packages, installed and uninstalled via the opkg package management system.
