SANS Internet Storm Center: port 4567
Notes:
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. 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/delivery 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. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.

Sinatra.rb applications use port 4567 by default.
I wish I could understand what this all means, pensiioners (not all) have only a vague idea how things work - so I can't tell how well you have done because I can't understand a word!! Sorry.
I can't understand any of this, I also am a pensioner and have no idea of what to do about this. I just use my computer normally but this is frightening me
This is typical and too complicated to understand. just do it if it is my interest
Username? password? dont @bother me cagain.
I do not understand any of this and as I use bullgaurd I thought I was cleared / covered from any Hackers
I have no idea how to fix this, a uncomplicated guide would help.
Wow.... All these comments are so pointless... THERE IS NOTHING TO BE FIXED ONLY IN CASE THAT PORT IS USED AS A BACKDOOR...Otherwise if you have a specific application that uses that port, there is nothing to worry about :/
Nothing to fix? Maybe not if you know what the hell it's all talking about. Reference to this has come up in Computeractive, so I looked at this site and don't understand any of it - don't even understand about the 'port'. It's like so many information sites - fine if you're a techie anyway. Come down to earth you boffins.
Ray, it is sometimes hard to address all audiences, that is why we have forums, you can ask questions and get more personal assistance.
Ports are communication channels, i.e. when two computers communicate on the internet, they send and receive information through "ports". Different programs/games/viruses are known to use different such "ports", and we have an extensive database that lists them all. Generally, if you don't know what's using a "port", you should try to find out, run anti-malware programs, etc. You are always welcome to sign up for our forums and ask if you need assistance. |
