I don't know if this is the place to put this link, but I've been using it for years and it is very handy. Ever been stuck trying to figure out which port number goes with which service? Sure, everyone knows that Telnet uses port 23, DNS uses port 53 and HTTP uses port 80...but what uses ports 13, 14149, and 27999? Wouldn't it be great to find a site that lists all of the port numbers and is easy to use, too (please don't say "iana"...they are the official site, but they drive me nuts)?

I thought I'd share this one in the hopes that some of you will find it handy. Cheers:

LOL - There's me thinking: "Now when did I miss this?"

Then I looked at the post date...



Good work Trip - I used this list a lot in the early days when I was first getting into security - especially useful to differentiate between the 'background noise' and the active scans when skimming through FW logs!

 

Zeb - when you say early days, are you referring to the 1940's?

 

Very useful link, thank you very much!

 

Hi, I'm just curious about the quote of the day port, 17. I never ever come across it. Can someone shed some light on this? What it is used for and what application it may use it and why I may use it?
cheers

^^ Bit of an old question to dig up but:

The Quote Of The Day (QOTD) service is an Internet protocol defined in RFC 865. It is intended for testing and measurement purposes.

A host may connect to a server that supports the QOTD protocol, on either TCP or UDP port 17. The server then returns a short arbitrary message. This was traditionally a random selection from a list of notable quotes.

The QOTD service is rarely enabled, and is in any case often firewalled to avoid 'pingpong' attacks.[1]

Current testing and measurement of IP networks is more commonly done with ping and traceroute.
