Linux denies permission on socket bind using boost asio

Question

I'm having a problem binding a socket and I get permision denied when running the program as a user. this line of code generates an error.

_acceptor = new boost::asio::ip::tcp::acceptor(io, boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), serverPort)); the error is

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> >'

what(): bind: Permission denied

However, if I run as root it works fine. I've tried disabling apparmor and firewall with

sudo service apparmor stop
sudo ufw disable

but I still have the problem. Am I missing something that could deny permision? I'd really like to figure this out as I don't like running my IDE and an unproven program as root.

I'm running xubuntu 13.10 with all updates installed.

On unix systems, the first 1024 port are restricted to the root user only so if serverPort < 1024 you should try something > 1024
