I would run out of numbers before I ran out of ways to interpret the meaning of ports in the Anarchy forum...

A port is basically the entrance to your computer from the outside world. Think of it as a door. A socket from a program opens up a port, (an example is apache opens up port 80 because that's the http port), and then other programs can connect to the computer trough port 80 once it's opened and something is listning. So the basic definition is a door into your computer. A port scanner will tell you what doors are open on the computer you are scanning.

Well Mac-10Daddy, while you telnet to each of the 65000+ TCP ports in DOS, we'll keep using port scanners...

Wtf is MDOS? is it like DDOS? or maybe the retard is thinking of MSDOS... anyways enough flaming. Think of ports as gateways, doorways, openings, or um ports on your computer that allow people to access the information on it, whether its in the form of a webserver, telnet server, mail server, or other things of the sort. Ports on your computer only to be opened if your acting as a server and for direct connections. Firewalls work by not allowing TCP conections to these ports, although they are still open...
The best way to close open ports is to shut down the service thats keeping them open such as NetBEUI that keeps 137 138 139 open I believe. How people acn do NBTstat look ups on you and all that. If you wanna learn more read about TCP/IP as you can cause that what the nets based on. Theirs shitloads that I could go into about ports but I dont wanna take the time. (If Im wrong about anything feel free to correct me).

lol
how old is this topic?
anyway. heh. MDOS is l33t! heh
does this mean that guy cant tell the difference between an OS and a port scanner, sad...
anyway, a port is where ships go.
think of your comp as a body of water, people are boats, and ports are places in which they can dock or enter it. Sometimes u need harbor passes like user names or passwords or bohemian slave girls. Sometimes the harbor cant be entered because its blocked off for the day(firewall). And maybe its just there because a program has to open a port to make a connection with another port. i.e. internet explorer to a website, and theres nothing u can do after u access the port. Basically like the port is there so 2 merchants can trade privately back and forth [Thumb]

ph33r my analogy.

lmfao

MsDos = lame not port scanners

Where the fuck do you come off saying Port Scanners are lame? It is one of the fastest if not the fastest way to see if there is any ports open.

MsDos at least the commands I know would be about the SLOWEST and least effective method of scanning for ports on a range let alone a single IP address..

Hm...just to note a few things that haven't been made clear enough:

1. There are two types of ports: TCP and UDP. TCP create three-way-handshake connections, UDP just receives packets.
2. I thought there were 32676 ports, not 65000+? Possibly I am wrong - 32676 is the limit on an int, but a unsigned int (this is for C datatypes) would run up to 65000+.
3. You should close all the ports you can on your computer.
4. You don't just "open" ports. You have to assign a program (known to the unix world as a daemon!) to listen to the port.

Now for some Mac-10Daddy bashing:
You are a worthless shit. Why the fuck do you contaminate these boards with your worthless comments. I can't believe I just gave up 1x10^-8375 cents worth of bandwidth and time to download and read the HTML that comprised your message. It's your kind that disgusts me. Get the fuck off this board you worthless turd. Go find an ugly girl to finger, or better yet, your dog.

What a worthless shit.

Scallion Corrections:

An int may consist of 2 bytes in 16-bit operating systems. But the int has 4 bytes on 32-bit systems. Output sizeof(int) on your machine to verify my words.

Yes, there are most DEFINATELY 65536 ports. 0-65535. Port 0 is reserved for a randomly selected available port by the system. In the TCP/IP protocol there is 2 bytes reserved for the port specs. So naturally they'll use it to its full potential.
