Would using ipchains / iptables work for you instead as an alternative ?

Hi undertow-dev

Is it possible to run undertow on <1024 port as root and then downgrade user to non-root one? Dropwizard (jetty in fact) framework has such feature (see #1), it just needs libsetuid.so loaded. Any alternative mechanism?

Regards
Grzegorz
