    Question open ports on my mac os x ...

    Hi

    I scanned my ports from 0 to 10000 and the result was this :

    Open Port: 80 http, www-http, www
    Open Port: 1033
    Open Port: 6700
    Open Port: 6701

    So I also scanned my http web server (hosted on a Linux cpu), the result was the same. (so I suppose it's the same for the most of UNIX like OS)

    My question is :
    why are 1033,6700 and 6701 ports made for ?
    why are they opened ?

    I tried to open a connection with them (without using any protocol, manually), it returned nothing.

    Thank you tell me more about them,
    Pierre.

    Hmmm...

    Do you have them hooked up to a router?

    The web site is behind a router, I think.
    My iMac, him, is connected through an Alcatel SpeedTouch USB modem (ADSL connection), so the having itself an IP, I suppose it is a kind of router.

    So I will answer yes. I think I'm behind a router (in both cases).

    Do you think is because of it ?

    PS: thank you for answering so quickly I was really surprised.

    I think so.

    I seemed to remember seing these numbers when my computer was behind a router. I believe at least the two 6000 range numbers are from the router. I can't remember where the 1033 comes from, are you running any Office v.X? That has a server that starts up with the computer and allows microsoft access to your computer. I can't remember if that is the port or not. Anyways, you probably have nothing to worry about. There is a web site out there that gives you the definitions for all of the ports but I can't remember what it is. I know, because I asked this question awhile back myself. Do a search here on the term "ports" and see what pops up. There should be at least one thread that can give you the link to the ports page.

    Good Luck,
    SA

    Port 1033 is netinfod on OS X. You probably shouldn't see port 1033 open on a Linux box.

    I haven't seen 670x open on my machine. To see what program is listening on a port, use lsof. For port 6700, type this in Terminal:

    sudo lsof -i :6700

    Type your password when asked. Look for a line with 'LISTEN' in it, that shows the program listening on that port.

    Thank you very much

    So I found what they are (6700 & 6701) :
    it's caracho server ports.

    I forgot I was running it.

    But what I don't understand it is why my web server (on a, very exactly : "Cobalt Linux release 6.0 (Shinkansen-Decaf) Kernel 2.2.16C28_III on an i586") has 1033 & 6700 & 6701 ports opened ... ??

    well, the server is hosting a lot of other web sites. It's a virtual server. Maybe what is happening is that somebody is connected behind the same router with a mac running carraxo server.
    I tried to open a carraxo connection with the server address but it didn't work ...

    well.
    So I'm very sorry about the 6700 & 6701 ports, I could have guessed it but thank you very much about the lsof command and the 1033 description.
    But can you tell me if it a problem ? I mean : can it be a secury problem to get it opened ? can somebody try something through there ?


    thank you,
    Pierre.
