TCP port checker (TCP port tester) is an online TCP client that checks TCP server connectivity and accessibility from the Internet. It can be used to check an arbitrary tcp port on a remote server. TCP port checker attempts to establish a TCP connection. If connection is successful you should be able to see it in the server logs.
The short answer: TCP is a transport-layer protocol, and HTTP is an application-layer protocol that runs over TCP. Keep reading for the long answer. To understand the difference (and a lot of other networking topics), you need to understand the i Applications running across networks can use any port they are configured to use. You need to clarify the source and destination of the rules to add context in order to understand this further, as TCP/UDP port 7 could literally be anything (SMTP, HTTP, HTTPS, etc) if the server has been configured that way. Port is an identifier which is capable to identify a socket. In case of the TCP, a port is a 16 bit integer, but there are other protocols as well (for example, on unix sockets, a "port" is essentially a string). The main problem is the following: if an incoming packet arrives, the kernel can identify its socket by its destination port number.

Web servers typically bind to the TCP port 80, which is what the http protocol uses by default, and then will wait and listen for connections from remote devices. Once a device is connected, it

NOTE: Although TCP 22 is not one of the ports the UniFi Network Controller operates on by default, it is worth mentioning in this article since it is the port used when UniFi devices or the controller is accessed via SSH. Jul 20, 2020 · Service names and port numbers are used to distinguish between different services that run over transport protocols such as TCP, UDP, DCCP, and SCTP. Service names are assigned on a first-come, first-served process, as documented in [ RFC6335 ].
