rozpojování PPTP tunelu

[dvcompt]

ahoj všem, prosím o radu,
použivám PPTP propojení k ISP z důvodu získání veřejky na routeru.
Bohužel se mě stává, že spoj se každý den rozpojí a interface PPTP není nahozený.
mohli byste mě poradit jak to obejít a kontrolovat to, tak aby v případě rozpojení
se to znovu spojilo.

děkuji všem za radu.

vypis syslog v dobe vypadku.

netmask   255.255.255.0
network   172.20.3.0
gateway   172.20.3.1

jako strasne jednoduchy reseni by bylo proste dat do cronu

Kód: [Vybrat]

*/5 * * * * /cesta/ke/skriptu
tzn, skript, co jen restartuje ty dva subsystemy, to by melo bohate stacit .. ten by si kazdych 5 minut overil, zdali funguje to spojeni .. obsah toho skriptu je jednoduchy, prose:

Kód: [Vybrat]

#!/bin/bash

restart_ppp0_nic="nejakej prikaz";
restart_pptp_service="nejakej_jinej_prikaz";

if ! { overeni, ze funguje to pptp }; than #### if NOT aka "!"
    $restart_ppp0_nic;
    p_exit=$?;
    $restart_pptp_service;
    s_exit=$?;
    exit $(($p_exit+$s_exit));
fi

exit 0;
ty prikazy si vyzkousj .. zavisi to linux od linuxu (unix od unixu), nemam ubu, ale prikaz service tam je pokud se nemylim, tzn neco jako

Kód: [Vybrat]

ifdown ppp0
ifup ppp0
service pptp restart
je to lehke, proste si zkus kteryma prikazama se to zabehu otoci a ty si dej do toho skriptu v tom cronu
