first 1024 ports blocked

Azureus did'nt work for me so i went about investigating and found out that for a normal user the first 1024 ports are blocked(all common service ports are here). I have no problem with this except that my blasted isp has blocked every port except a handful within the first 1024. how do i unblock these ports for normal user as everything works fine only for the root user.

Re: first 1024 ports blocked

well, on a linux system, unless your firewall is configured to do so, ports are not blocked to users.

it's actually standard practice to have daemons such as apache or lighttpd running as an underprivelidged user.

as for dealing with ISP blocks. you cannot unblock them, only the ISP can. Maybe you should have read the terms of use before signing on.

Either one is irrelevant anyway, Azureus typically uses ports 6881-6889 IIRC.

Re: first 1024 ports blocked

You are wrong iphitus. Unprivileged users can not open "privileged" ports. A program like apache has to run as root, open the port and can then drop its privileges.

Unfortunately, I do not know how to work around this either.

I never realised, and I was sure I had made one while playing in python.. but I guess i musta been running a higher port.
