I can buy Win95 boxes not quite knowing how to do TCP, but
45dbcfcd == 205.207.219.69 == a Solaris 2.5.1 + patches box, and
83dbcfcd == 205.207.219.131 == a Linux 2.0.17 box.

Mar 11 13:28:32 neon kernel: TCPv4 bad checksum from 45dbcfcd:0016 to 39dccfcd:0
490, len=232/232/252
Mar 11 13:29:25 neon kernel: TCPv4 bad checksum from 45dbcfcd:0016 to 39dccfcd:0

Mar 11 12:44:10 neon kernel: TCPv4 bad checksum from 45dbcfcd:0016 to 39dccfcd:0

Is this really because there are checksum bugs in Solaris and Linux?
