What uses port 8080?

Answer 1

Port 8080 is an alternative to the port 80 used by http and web services.

History:

The internet was largely born on UNIX-based systems and servers. UNIX enforces the notion of the first 1023 "privileged ports" which can only be opened by services running with so-called "root", or administrative, privileges. Historically, this meant that only authorized system administrators were able to establish and operate a web server on port 80 since this was within the first 1023-port privileged region. Therefore, when non-administrators wished to run their own web servers on machines which might already have a server running on port 80, or when they were not authorized to run services below port 1024, port 8080 was often chosen as a convenient place to host a secondary or alternate web server.

Answer 2

It is an unassigned port. Some known uses of TCP 8020 include "Intuit Entitlement Service and Discovery" (Quickbooks), as the default port for Gateway to Cisco PAM communication, and the Aloha Point of Sale (AlohaPOS) upload to HotSchedules.com. Many others use it as an alternate HTTP port in much the same way 8080 is used.

Answer 3

Port 8080 is a common alternative to port 80. Port 80 is used for HTTP / web servers such as Apache or Microsoft IIS so port 8080 is often used the same way.

Port 8080 is also frequently used for proxy servers which are servers that fetch and cache content for the client computers that are configured to use that server.
