The OpenBSD toolbox for network debugging just got better.
In a recent
thread
on tech@ titled pfctl show fragment info,
Alexander Bluhm (bluhm@)
posted a patch to enable packet reassembly statistics in
pfctl(8).
Several other developers joined in,
and Claudio Jeker (claudio@) suggested that
systat(8)
should too be enhanced to display packet reassembly data in
pf(4) related views.
This suggestion was well received, and the resulting code has now been committed,

Framgent count and statistics are stored in struct pf_status. From there pfctl(8) and systat(1) collect and show them. Note that pfctl -s info needs the -v switch to show fragments. As fragment reassembly has its own mutex, also grab this in pf ipctl(2) and sysctl(2) code. input claudio@; OK henning@
and will be available in -current snapshots.
If you know you occasionally or even frequently need to see fragment reassembly statistics, you will appreciate this improvement to the two crucial tools pfctl(8) and systat(8).
