    do you really know what you are talking about? then it is some issue i never heard of.
    1. agent: do you mean ssh-agent? just configure correctly to avoid man-in-the-middle attacks.

    2. proxy: you are running a proxy server that can be accessed anonymously from the web. either setup your proxy or firewall to only allow connections from your local machines.

    I could think limited to a few ports !
    even if i misunderstood the whole point, just block the ports on your firewall?!?

    SuSE (www.suse.com) made a very nice "Personal Firewall" script that should work with any distribution with minor modifications and can offer you firewall-functionality even though you are connected directly to the net.

    (it only works with 2.2 kernel as far as i know...)
