Sorry for bothering all. I have started working in dtn since one week now. I am unable to configure it to create multiple nodes. I tried making different config files and starting them separately in same machine, but only the first one is started. The ones after that says api port not initialized. I changed api_port in config file, but all configs still tries to use port 4550.
