Hello Mehrdad,
how did you install IBR-DTN? If IBR-DTN was installed from the repositories, the daemon will start automatically. In this case a dtnd is already running on port 4550, so a second, manually started, dtnd cannot bind to it. You could check this by trying to connect to this port via telnet (or by looking at the output of "netstat -tulpen").
Otherwise you could enable the debug output of dtnd (start with -d 90) to get more information.
