Description

The remote host responded with a UDP packet whose IP ID was zero. Normally the IP ID should be set to a unique value and is used in the reconstruction of fragmented packets. Generally this behavior is only seen with systems derived from a Linux kernel, which may allow an attacker to fingerprint the target's operating system.
