    Hi!

    Just did a port scan from network utilities. And there are a few I'm not sure whats doing. I've used the Well known TCP and UDP ports used by Apple devices as a reference.

    These are my open ports:
    Code:
    [COLOR="Red"]	 Open TCP Port: 	983[/COLOR]
    	 Open TCP Port: 	993    		imaps
    [COLOR="red"]	 Open TCP Port: 	1017[/COLOR]
    [COLOR="red"]	 Open TCP Port: 	1021   		exp1[/COLOR]
    	 Open TCP Port: 	17500
    Anyone got an idea of whats using them? Thanks!

    Did you try Google?
    17500 seems to be dropbox. 993 is IMAP, email it would seem.
    Not sure about the others but I'm sure Google can find them.

    Yes I tried google, googling it is way easier than posting a forum post. :)

    I was after the red ones, even though I did not specify that.

    RE: /etc/services...

    Hi,

    The file "/etc/services" lists the ports/protocols that your computer may be using via configuration in various plists.

    Regards,
    Switon

    I forgot to post. I could not find useful information.
    I would look into switon's hint about /etc/services
