[Cialug] Rogue triggering reboot!

[L. V. Lammert]

This SEEMS to indicate that a packet received on a public IF that has no
open ports triggered a reboot:

Oct 14 17:31:36 <machine> kernel: IPv4: martian source 206.197.251.9 from 60.24.136.201, on dev br3
Oct 14 17:31:36 <machine> kernel: ll header: 00000000: 00 e0 81 cd 21 b1 00 b0 c2 88 54 1c 08 00        ....!.....T...
Oct 14 17:31:44 <machine> systemd[1]: Received SIGINT.
<reboot in process>

OpenSuSE 42.1, .. host and five VMs.

This server has been rebooting at random times, .. I finally got into
BIOS and set BMC to reboot instead of shutdown (so it doesn't just go to
sleep, but it still is frustrating.

Any thoughts on troubleshooting?

	TIA!
