I rewrote it quickly to C [1] (and changed the embedded binary to be aarch64).

Unfortunately it fails on calling bind() on my device, so probalby Android doesn't ship with that kenrel module by default :(. So no freedom for my $40 phone.

Putting it out here, maybe somebody else will have better luck.

There’s SELinux, everything is mounted nosuid, barely anything runs as root except init. I doubt it.

I’ve poked around on my phone and it didn’t work:

    File "/data/data/com.termux/files/home/a.py", line 5, in c
      a=s.socket(38,5,0); # ...
    File "/data/data/com.termux/files/usr/lib/python3.13/socket.py", line 233, in __init__
      _socket.socket.__init__(self, family, type, proto, fileno)
      ~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  PermissionError: [Errno 13] Permission denied

Android is smarter than setuid + system partitions aren't writable.
