Dear AO
Anyone have some interest in ports and their functions you might want to look at .this
Thanks! \/IP3R, that is going to be a HUGE HELP! Awesome!
Someone previously posted this and I put it in a txt file
what about the last 535 ports? (as there are 65535) are they in the list to?

Very handy, thanks for sharing.
This can also be found on any *nix box by doing a 'cat /etc/services'
Thanks for the link. I will definitely be bookmarking that for future reference.
From what I can see the owner of that site tries to update the list periodically. It may prove helpful in the future if you have weird activity on some port to visit this site and see what it might be.
I like the fact that he not only enumerates the ports and what services run on them, but he talks about the common applications that may use it and the potential problems associated with it. It is much more informative than simply associating a service name with a port number.
Great Information!
That's a great help thanks.
then there is always the source to go to, and one that is constantly updated as ports change:
http://www.iana.org/assignments/port-numbers
I know it's a bit different than the one that was originally posted, but I use the IANA reference for just about all of my port look ups now.
mark_boyle2002, your version could be/become outdated (is it not the list I have posted several months ago?). Go directly to the source: here

edit: sorry Lv4, I have just discovered my link is redundant. We must have posted nearly at the same time.
ICMP ports...wtf? :)Quote:
ICMP ports and code types, uncompressed
hehe, no problem. We were only a minute apart from posting :)
I used to surf the RFA's for this, but those things become outdated pretty fast too. I figure the IANA, since they are the ones that assign the port numbers in the first place, are probably the resource to use.
\/IP3R Awsome link I have been wanting to look for a site that had all the ports on it but couldn't find one till now. I have been also wanting to learn what they do, and that site is so helpful.
>Thanks again!
Just a word of advise to all of the newbies.
Although this list is a fantastic reference tool, I would advise against taking the registered port listing for gospel if you are using it to determine what applications are listening on your own machine.
Just because a machine is listening on port 22, doesnt always mean that the daemon opening it is the sshd....
Nowdays you can basically choose what port you want an application to listen on, including trojans. What if someone compromises you FTP server, disabled the FTPd, installing a trojan, and making it listen on port 21. At a glance, the owner wouldnt think twice about having port 21 open on his FTP Server, right?
If you would like to see what applications are opening ports on your machine, I would be using tools such as fport or active port for Windoze systems, or performing a netstat -anf for *nix machines.
