how to bind a <1024 port number with a non root users
Hello. I was wondering if anyone knows the way to setup a non root account to permit binding ports less than 1024? I.E. I have set up a Lotus Domino Server 6.0.1 trial version on a Compaq Proliant ML370, running Redhat - my favorite - Linux 9.0. It seems that when I run the "server" program for LD - Lotus Domino - on the console I see an error message about, pop3, imap, httpd, services not able to bind to their well known ports, for one of two reasons: 1) port already in use, or 2) permission denied. After examining the ports that are in a listening state, I see that none of the mentioned services are running, which means that the LD server cannot bind these programs on their well known ports, because the user account starting the LD server is a non root account. Also when I use "chkconfig --list | grep ....." for instance httpd, I see that this service is off in all run levels. So I know the ports are not active and that this is simply a case of inadequate permissions.
So what I'm looking for is a way to allow an arbitrary non root account to bind to these ports. I remember reading about this and being able to do it, I just can't remember where or what book I read about this in. Any help will be greatly appreciated!!!! Thanks.....
