Unusually large? number of connection attempts to MY system...

[imagenious]

In reviewing these connection attempts, I find that they all are of 3 "types"

1. "Stealth Mode connection connection attempt to UDP (my IP number)"

2. "12190 Deny TCP (their IP number) (my IP number) in via pppO"

3. "20000 Deny ICMP (their IP number) (my IP number) in via pppO"

Now, what are they "sending" and what are they "getting" - and if they are getting nothing in the way of a reply, as I suppose, how would having my password help, or would it?

Some of my port numbers being "queried" are: 2968, 2967. 1026, 1027, 1028, and 1434.

Thanks.
