sdtcon is preconfigured to tunnel VNC, RDP, HTTP, HTTPS, SSH and Telnet services. The user may modify the pre-canned services and specify new custom services using arbitrary port numbers and clients. sdtcon also provides a client for tunneling UDP services over SSH.
User Datagram Protocol or Universal Datagram Protocol: Connection: Transmission Control Protocol is a connection-oriented protocol. User Datagram Protocol is a connectionless protocol. Function: As a message makes its way across the internet from one computer to another. This is connection based. UDP is also a protocol used in message transport 本項ではTCPやUDPにおけるポート番号の一覧を示す。. コンピュータネットワークにおいて、インターネット・プロトコル・スイートのトランスポート層にあたるTransmission Control Protocol (TCP) やUser Datagram Protocol (UDP) では、他のプロトコル同様、ホスト間通信のエンドポイントを指定する際に数字の The Secure Shell protocol (SSH) 2 is widely used for purposes including secure remote administration, file transfer using SFTP and SCP, and encrypted tunneling of TCP connections. Because it is based on TCP, SSH suffers similar problems as are motivating the HTTP protocol to transition its transport to UDP-based QUIC [QUIC]. Question about tunneling UDP over SSH is a matter of tunneling UDP over TCP. There are special tools like udptunnel. Update: Just found a simple way tunneling (UDP private port) via SSH on virtually a bare shell (nc + ssh) without any external dependencies.
The SSH protocol does not include anything for UDP forwarding. So you need to run some program at the SSH server side which will send the UDP packets for you, and receive sent ones. I don't know the SNMP details, but for simple cases you can simply start netcat or socat with an exec channel, sending the packets with by standard input/standard
TCP and UDP - linkedin.com So there are situations where UDP being connectionless can even do things like transfer files. However, gosh, 95, 98% of everything that happens on the internet is TCP.

Jan 23, 2018 · In the green filter field, enter the below pattern to filter the traffic by the selected UDP socket port: udp.port == 7077. Send messages from the client- to the server socket to capture traffic. To view the payload of a UDP packet, expand the Data node and click on the [Length: ..] item.
Online TCP UDP port finder - adminsub.net Mar 30, 2016 Port 22 and Relation with SSH Protocol – POFTUT TCP Port 22 or UDP Port 22. Port 22 generally referred to as the TCP port 22. But there is also a transmission protocol named UDP which has different behavior than TCP. SSH needs reliable connection which is provided only by TCP protocol so UDP port 22 is not a popular port. Change SSH Port In the Server. By default, SSH runs on TCP port 22. Test connection to udp Port using telnet command Jul 21, 2016
