Thats my big question, as i wrote this is the situation:

- On port 3600 UDP is a program that sends information
- I want to listen to this information

Quote:

root@chieftec:/home/wolfgang# lsof -i | grep -i UDP
hdeam 807 root 4u IPv4 4277 0t0 UDP *:3600
ldeam 2125 wolfgang 3u IPv4 35397 0t0 UDP *:39563

"hdeam" sends information....

ldeam is a program that gets information from hdeam - and I want to get information, too!

In this case I think i need just a client?!

But with urrClient I don't know how to listen because I don't want to send to the socket, just read from it.

So I really don't know if I need a server and a client or just a client for this. Whats the schematic of such a connection?
- Do I have to start a own server on another port than 3600, connect through another socket to UDP 3600 and tell the server to establish a connection to my own server?
OR
- Do I just have to connect to UDP 3600 Port with a client and listen? (If yes - I tried but in UrrClient for example is no method for listening..)
