I want the kernel to choose an available port for me. On the other hand, I want to indicate which local IP to use, since I'm running a few nics. I've tried combing through the maze of socket I'm using latest debian relese and i need to do some port forwarding, but i dont know how.I have 2 stream sources coming to my server on the same udp port from 2 diferent ip-s 192.168.1.2:1003 via udp to 192.168.1.4 (server) 192.168.1.3:1003 via udp to 192.168.1 I would like to test UDP connectivity with iperf3 but do not know how to start it in UDP server mode. iperf3 -s only opens a TCP socket: root@srv ~# lsof -i -P | grep iperf3 iperf3 I have to capture all the UDP packets sent from host A to any UDP port of host B. The following, if run on host B, doesn't work.

If you want to use webrtc, you will have to implement webrtc on your server – Samir Das Apr 9 '15 at 7:27 2018/11/30 So I can use this netcat command to check if a UDP port is open: $ nc -vz -u 10.1.0.100 53 Connection to 10.1.0.100 53 port [udp/domain] succeeded! Unlike TCP, UDP is connectionless (fire and forget). So at a high level does anyone know how netcat knows the Bit2Me is the leading Spanish company in buying / selling of Bitcoins.

Thus, the Compact Blocks scheme in Bitcoin Core is critical to performance. Because the Compact Block design was being done simultaneously with the work on FIBRE, the cmpctblock message format was designed to ensure it fits neatly into a UDP-FEC-based relay mechanism.

As far the common Bitcoin P2P protocol goes UDP is not an especially good fit for most operations that it performs. Bitcoin needs to reliably send messages far larger than an IP packet, like transactions and blocks. Although the internet is "reliable" packet loss rates of 1-3% are common. See full list on en.bitcoin.it UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data. When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. Because you want reliability. The unreliability of UDP would add yet another layer of complexity to the system.
