    Hi
    
    I received approximately 100 of these within the space of 30 minutes or so from numerous different IP addresses and on my /29 block (2/3 machines and also the broadcast/and network addresses). Now I've had a few shall we say erm, "funnies" going on on this one machine lately with problems when it's rebooted which seem to be fixed by a kernel rebuild, but that could be a hardware problem. however it could be more indicative of an attack maybe even a successful one.
    
    Aug 18 10:46:14 thunder snort: [1:483:2] ICMP PING CyberKit 2.2 Windows [Classification: Misc activity] [Priority: 3]: {ICMP} 80.253.133.136 -> xx.xx.xx.120/123/125/127
    
    120/127 are the end of my 8 IP block, 125 is the machine with the funnies, and 123 is a windows 98 vmware session that I've only just finished installing windows in.
    
    it's always those same IP's and never any of the others.
    
    my question is, what can i do to see whether my box has been compromised (a rebuild's not much a problem as i was going to do it anyway :P) and if could any of you "1337" (i use that term loosely) help me.
    
    regards
