I was analyzing at my TCPDUMP logs from yesterday and found this entry,

----------------------------
(0)root_at_myhost:/backup/net-log.d => tcpdump -r tcpdump-051701 'dst port 111 and not src host 1.1.1.1'

23:32:46.554793 h24-67-209-122.du.shawcable.net.4407 > cb202558-a.rmvll1.il.home.com.sunrpc: S 2955654859:2955654859(0) win 32120 <mss 1460,sackOK,timestamp 114022005[|tcp]> (DF)
----------------------------

I have changed my address in the tcpdump filter. Someone here is probing
someelse's machine and why did this get to my machine? Is there anything else
I need to look at in the tcpdump logs?

Thank you in advance for any help.
