> I'm using DCCP in Linux 2.6.14. Does anybody know  why I always get error 103 (ECONNABORTED) "Software caused connection abort" when connecting to the remote server?

Are you using the loopback interface?
Is it the case that the server sends data and then closes the connection?

Try tcpdump and see if the connection actually happens, i.e. are packets
transmitted and ACKed?  Also, does it work sometimes [connection established]?

Try this patch if you have the above symptoms:

and let me know if it's any better.
