PC-Anywhere |
Old verson of pcAnywhere uses port 22/udp (no relation to ssh and port 22/tcp).
The real pcAnywhere port is 5632. The value 0x0016 (hex) is 22 decimal; the value of 0x1600 (hex) is 5632 decimal. Some say that pcAnywhere had a byte-swapping bug that led to its incorrect use of port 22. |

Secure Shell - most common use is command line access, secure replacement of Telnet. Could also be used as an encrypted tunnel for secure communication of virtually any service.
Some trojans also use this port: InCommand, Shaft, Skun |

TCP ports use the Transmission Control Protocol. TCP is one of the main protocols in
TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery.
