Is there a way I can remap the port a protocol uses with the Terminal in OS X? I'm trying to use FTP at a place where I think that useage of the usual FTP port is blocked. So I'd like to remap the port of FTP to the Internet port (80?) so I can use FTP here.

not really...and you certainly can't use port 80.
but what you can use is a port above...1024 i think. those are unmapped ports. at the very least...ports above 3000 are unmapped.
i think what you do is put a colon after the ip address, and then the port number

Ok, so let's say I'm behind a firewall that I have not control over, like at the library.
Would I do a port scan to see which ports are open and then use one of those as the remapped port?
Also, where do I add the colon after the IP? In Terminal or in a browser?

it doesn't matter if you're doing it from the terminal or a browser...it'll look like this; 127.0.0.1:3000
but now comes the time that i ask what exactly you're doing. because if you're doing this from a library, then something tells me you're doing something you shouldn't be doing...

I'm just trying to download a file from a site. The file is not accessible through a browser so I have to use FTP. Yes, I'm at the library and they block FTP access ports.

Have you asked them to unblock the ports? Its bad enough when they block SSH and stuff let alone FTP!

//wow, mac users that actually know something about their computers, amazing.

Yeah well, they won't block nothing. A "security loophole" the guy called it when I asked him.
Is there anyway around this "loophole" that I can execute using the lovely Terminal?

Port scan is in progress...

Anyone have a solution?

- tell them to fix their supposed 'Internet Access'
- Use a program or web service that can access the FTP site via HTTP? (i think they exist?)

it's been a little while since my 1337 haxor days...what did port scan turn up?
