"Could not find a suitable free port" as normal user

[Daan]

Hello

I'm trying to get DC++ working in Linux. (DC++ is a peer-to-peer file sharing thing.) I have installed linuxdcpp, and I can connect to a hub, but I do not get any search results. In Windows DC++ works just fine. And I use the same settings! These are: Firewall with manual port forwarding for the incoming connections (hub/UPnP override not allowed) and Direct connection for outgoing.

Now, when I start linuxdcpp as normal user from a terminal it says

daan@schmauck:~$ linuxdcpp
Loading: Hash database
Loading: Shared Files
Loading: Download Queue
StartSocket (tcp): Caught "Could not find a suitable free port"
StartSocket (udp): Caught "Could not find a suitable free port"

However, when I run linuxdcpp as root, I do not get the "Could not find a suitable free port" error and I can search.

How do I get to use DC++ as normal user?

OK, just in case anyone wants to know: I fixed the problem by using a port higher than 1024. On Linux, you need special privileges to use ports lower than 1024.
