Hi,
don't blame me for asking such a question in the LKML, but i already asked it in other linux-newsgroups. i haven't got any real answer yet.
my problem is, that i want an application to listen on a priviledged port (e.g. port 80) and to run as a "normal" unpriviledged user (e.g. wwwrun). Well - how? The application is not a C/C++-application, so i cannot ask the author (myself) to implement a mechanism to switch the userid (e.g. like apache does it).
So is there any machanism to bind that permission (to listen on a priviledged tcp-port) to a specific user or a specific process?
The application is written in Java. Of course Java could implement userid-switching, but the linux could also have an ACL for that. So please don't answer with "go and ask Sun for that feature". I already considered that.
Thx Sven
