This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
Local port forwarding is the most common type of port forwarding. It is used to let a user connect from the local computer to another server, i.e. forward data securely from another client application running on the same computer as a Secure Shell (SSH) client. By using local port forwarding, firewalls that block certain web pages, can be ...
Some of the applications below may require features that are only available or compatible with specific SSH clients or servers. For example, using the SSH protocol to implement a VPN is possible, but presently only with the OpenSSH server and client implementation.
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system , a port is a logical construct that identifies a specific process or a type of network service .
PuTTY is a Win32 SSH client that supports local creation of SOCKS (dynamic) tunnels through remote SSH servers. Secure ShellFish is a SSH client for iOS and macOS that includes a SOCKS server. ShimmerCat [ 20 ] is a web server that uses SOCKS5 to simulate an internal network, allowing web developers to test their local sites without modifying ...
In particular, in multicast socket networking, an example of promiscuous traffic is when a socket configured to listen on a specific multicast address group A with a specific port P, noted A:P, receives traffic from A:P but also from another multicast source. For instance, a socket is configured to receive traffic from the multicast group ...
This helps minimise effects of jitter and bandwidth changes, while error-correction mechanisms help minimise packet loss. SRT supports end-to-end encryption with AES. [ 3 ] When performing retransmissions, SRT only attempts to retransmit packets for a limited amount of time based on the latency as configured by the application.
This port remains allocated during the whole conversation and effectively limits the number of outgoing connections from each of the client's IP addresses. If an application fails to properly close unrequired connections, a client can run out of resources and become unable to establish new TCP connections, even from other applications.
