Hi all!
FreeBSD 6.2-release.
I'm having trouble with arp:
arp: unknown hardware address format (0x4500)
and
arp: unknown hardware address format (0x4242)
these messages fall on the console in a plenty.
I do tcpdump -exn "arp[0]=0x45 and arp[1]=0":
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on xl0, link-type EN10MB (Ethernet), capture size 68 bytes

In the arp-table of my network there is not MAC-address 00:02:55:53:46:13.
Where is it address from?
How does it influence on safety?
How to solve this problem? Thanks
