Sadržaj init-b-out-ba paketa¶

root@router-wan-sa-1:/# ipkg files init-b-out-ba

Package init-b-out-ba (0.0.3-1) is installed on root and has the following files:
/etc/init.d
/etc/init.d/init-b-out-ba

Karakteristike init-b-out-ba skripte¶

init-b-out-ba skripta radi sljedeće:

1. ako firmware tek inicijaliziran vrši auto recovery proceduru
2. mount-a /mnt/1 shfs, ako su shfs varijable setovane
3. pokreće mrežnu init skriptu /mnt/1/etc/init.d/init-b-out-ba, ako postoji
   • uobičajeno, mrežna init skripta kopira u /tmp/
     • firewall - <hostname>.fw
     • router.sh - inicijalizacija route-a
   • još jednom restartuje wan konekciju
     • za bihnet: restartuje freezone, koja opet refreshira i glavnu wan-bihnet konekciju

Podešenja /etc/hotplug.d/iface¶

Ovo su skripte koje se pokreću prilikom podizanja wan interfejsa

hotplug.d/iface firewall¶

/etc/hotplug.d/iface/09-firewall

. /etc/functions.sh

config_cb() {
if [ "$1" == "system" ] ; then
  SECTION=$2
fi
}

config_load system
config_get HOSTNAME $SECTION hostname
COMMAND=/tmp/${HOSTNAME}.fw

[ "$ACTION" = "ifup" -a "$INTERFACE" = "wan" ] && {
        [ -x $COMMAND ]  && {
                $COMMAND 2>&1
        } &
}

hotplug.d/iface routes¶

router.sh se pokreće svaki put nakon ifup wan-a

/etc/hotplug.d/iface/10-routes¹

COMMAND=/tmp/routes.sh
[ -x $COMMAND ]  && 
{
   $COMMAND 2>&1
} &

return 0

routes.sh¶

Kao najbitnije, routes.sh setuje freezone route

/mnt/1/routes.sh

#!/bin/sh

IP_WAN=`ifconfig ppp0 | grep -o  "inet addr:\(.*\) P-t-P" | sed -e "s/inet addr://" | sed -e "s/ P-t-P//" | sed -e "s/ //g"`
echo ipwan=$IP_WAN

add_route() {

local net=$1
local via=$2
local dev=$3

echo $net, $dev

# if you say:
# ip route add 195.222.33.151 dev ppp0
# then ip route show  =>
#                          195.222.33.151 dev ppp0  scope link

if [ "$via" == "link" ]
then 
  ROUTE_EXISTS=`ip route show  | grep -c "$net dev $dev.*link"`
else
 ROUTE_EXISTS=`ip route show  | grep -c "$net via $via dev $dev"`
fi

#echo net=$net, via=$via, dev=$dev,  exists=$ROUTE_EXISTS

if [ "$ROUTE_EXISTS" == "0" ] 
then
  if [ "$via" == "link" ]
  then
     echo ip route add $net dev $dev
     ip route add $net dev $dev
  else
     echo ip route add $net via $via dev $dev
     ip route add $net via $via dev $dev
  fi
fi

}

¹ originalna openwrt image sadrži 10-routes skriptu koja čita, flash/uci varijable, kako se sa tim podešenjima nisam snašao napravio sam router routes.sh koja se pokreće
