I only have an @home connection and 1) Even though the servers I've seen look benign, what if they had an exploit, which would open up your system, and really make it exploitable... 2) Why do you want the extra bandwidth being used by these people, unless you have bandwidth to burn? > I'm wondering where all these crackers are finding my IP from. 3) The IP is probably found by people that understand what bridge group IP ranges or PPP pools are available for DSL or dialup connections. This isn't that hard, since many ISP's use host names that usually have ppp, dialup, 33k, 56k, dsl, or some other indicator. Once that is found, they usually scan that subnet for holes, because, unlike many people on this list (there's probably a couple black hatters, though ;), they have way too much time on their hands :-) HTH Jon > > David > Software Engineer - NetManage > Work email: david.daugherty@netmanage.com > Home email: doc@wcug.wwu.edu > ICQ 21106703 > Washington State Resident > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
