traceroute ICMP packets

[lfabian () CRIC CHEMRES HU (Laszlo Fabian)]

Hello,

My Linux box has recently logged some traceroute ICMP packets. Of course,
I did not traceroute these hosts. (Packets from hosts between my
computer and the source IPs are missing as well.)

Do you have any idea what this can be?

Here are the (ipchains) logs:
(x.y.u.v is the IP address of myhost)

... (more packets from these hosts with similar delays between them)
