    DDos Attack

    Hi,

    This is not really a Ubuntu question, but I need some good advice. And this is a good place to start.

    I have a webpage set ut at one.com
    Now they have blocked my access to all of one.com because they say that there has been a DDos attack from my IP address.

    Any suggestions on how to search my computers for the source of this attack? I now that this is not intentionally...

    Some more information: It seems like it is one.com that blocks and register as an attack because of to many FTP uploads. Any suggestions on how to log FTP connections from my IP?
