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

[Andrej Antonov]

good day!

files /etc/ppp/firewall-* (various scripts) --- use command: iptables ...

but MUST use command: iptables -w ...

utility iptables (without option -w) -- may exit with error if other
parallel script is running.


additional info (for implement):

keyword ``-w`` may not present in not-modern linux-distributives.

as solution -- may be need use wrap-function [iptables_wrap] in
scripts -- like in this example:

if iptables -w -nL >/dev/null 2>&1
then
  iptables_wrap () {
    iptables -w "$@"
  }
else
  iptables_wrap () {
    iptables "$@"
  }
fi




thanks!
