Αντικείμενο: [DNG] Sysvinit script doesn't trigger on boot
Hi,

I made a script to load rules for an nft firewall.
It's executable, runs from the command line
with start/stop/status options.

But it doesn't start during system boot.

I created symlinks with update-rc.d
and links appear in the rc*.d directories
where * is 2,3,4,5.

For example:

$ ls /etc/rc2.d | grep firewall     
S02firewall


Also, I couldn't find evidence in any log files.
There was no /var/log/firewall, nothing in /var/boot.

TIA for any suggestions.

Here is the script:

$ cat /etc/init.d/firewall

#! /bin/sh
### BEGIN INIT INFO
# Provides:          firewall
# Required-Start:    
# Required-Stop:    
# Should-Start:      
# Should-Stop:       
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: Initialize firewall
# Description:       Start nft firewall settings for desktop
#                    Applies to first wifi device
### END INIT INFO


PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH

. /lib/lsb/init-functions

do_start () {
    #WLAN=`cat /proc/net/wireless | perl -ne '/(\w+):/ && print $1'` 
    # above isn't available until wifi device is associated
    WLAN=`iwconfig | perl -ne '/(wlan\d)/ and print $1'`
    export WLAN
    log_action_msg "Starting firewall on wifi device $WLAN"
    perl -pe 's/WLAN/$ENV{WLAN}/' /etc/nft-firewall > /etc/nft-firewall-wifi
    nft -f /etc/nft-firewall-wifi
}


case "$1" in
  start)
    do_start
    ;;
  stop)
    log_action_msg "Stopping firewall"
    nft flush ruleset
    ;;
  status)
    log_action_msg "Showing firewall ruleset"
    log_action_msg "# start ruleset"
    nft list ruleset
    log_action_msg "# end ruleset"
    ;;
  *)
    echo "Usage: $0 start|stop|status" >&2
    exit 3
    ;;
esac
