Finally masscan working for termux without connect to wlan.

[anasfanani]

I spent 2 days search how to run masscan with termux only with LTE network, because limitation of rmnet_data, I try to create dummy interface ethX, virtual eth pair to network namespace, deal with iptables route, etc really make frustation, only can run masscan with success while connected as client to AP.

Recently I discovered to install docker in termux https://gist.github.com/oofnikj/e79aef095cd08756f7f26ed244355d62 , because manual way is too complicated, I want easy way instead, go to https://github.com/egandro/docker-qemu-arm and follow instruction to install.

Login to alpine linux and install masscan and libpcap-dev with:

apk update
apk add masscan
apk add libpcap-dev

Result:
