Re: allowing ordinary users to open privileged ports

      Has anyone in the list successfully tried allowing ordinary
users to open privileged (< 1024) ports? We have a solaris 8 on sparc
machine running an (java) application that normally uses ports > 1024;
however a client requested the application to use privileged ports
instead.



Could you keep the app running on it's existing high numbered
port and have a process redirect traffic to it from the low
numbered port?  rinetd listening on port 800, redirecting to
port 8888 for example.  Could do the same thing with tcp
stack games depending on what you have available too, or on
a firewall/etc that's in front of it.
