screenstat - Show gateway screening statistics
The screenstat command displays statistics about kernel gateway screening. The display is sent to the standard output.
The format of the screenstat report is as follows:
total packets screened: 16754
total accepted: 15149
total rejected: 12
because buffer was full: 0
because user was out of sync: 0
because too old: 1592 total dropped: 1592
The total packets screened count shows how many packets have been received for forwarding. The accepted and rejected counts show how many packets were forwarded or dropped based on instructions from a user-level process. The total dropped count shows how many packets were dropped for other reasons: lack of space in the kernel buffer, errors by a user process, or packets that were queued for too long. If the counts do not add up, some packets are currently queued in the kernel.
