Как проверить

Как проверить

Если что–то будет идти совсем не так, упадет ядро :) или блокируется весь трафик!

Работу демона netams можно проверить через просмотр состояния сервиса data–source:

netamsctl show ds

Data–source type NETGRAPH source netams::9 loop 0 average 0 mcsec

Perf: average skew delay 0 mcsec, PPS: 0, BPS: 0

IP tree: 7 nodes [12] + 4 dlinks [1024] + 4 unodes [24] = 4276 bytes

Flows: 0/0 act/inact entries (0 bytes), 3 flows sent

HASH: size=65536, 0 flows hashed, 0 nodes used, max chain= 0

FIFO: 0/2 used/ready messages, each 108, total 216 bytes

ds_netgraph data messages: 3

netams: mode=2, pkt_rx=201, pkt_tx=169

flows: active(now)=3, queued(now)=0, blocked(total)=0, total=4

Работа модуля ядра видна через ngctl:

ngctl msg netams: info

Rec'd response «info» (1) from «[3bb]:":

Args: { packets/in=254 packets/out=202 mode=2 debug=1 active_flows=3 total_flows=9 default_policy=2 }

При включенной отладке модуля (через ngctl msg netams: debug 1) на консоли и в dmesg видно много подобных строк:
