[RP-PPPoE] bug-report: scripts /etc/ppp/firewall-* (error iptables invoke)

[Andrej Antonov]

good day again! :)

may be next hack is better:



if iptables -w -nL >/dev/null 2>&1
then
  iptables_wrap () {
    iptables -w "$@"
  }
else
  iptables_wrap () {
    flock -x /run/iptables.lock iptables "$@"
  }
  touch /run/iptables.lock
fi



thanks!
