.SH Syntax
.B /usr/etc/screenstat
.SH Description
.NXR "screenstat command"
.NXR "gateway screening" "showing statistics"
The

command displays statistics about
kernel gateway screening.  The display is sent to the
standard output.
.PP
The format of the 
.PN screenstat
report is as follows:
.nf
.EX 0
total packets screened: 16754
total accepted: 15149
total rejected: 12
packets dropped:
        because buffer was full:        0
        because user was out of sync:   0
        because too old:        1592
total dropped:  1592
.EE
.fi
The 
.PN "total packets screened"
count shows how many packets have been received
for forwarding.  The 
.PN accepted
and 
.PN rejected
counts show how many
packets were forwarded or dropped based on instructions from a user-level
process.  The 
.PN "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.
