nu am stiut ce sa ii fac,am tot incercat sa modific si etc,dar kkt

script  2

#5 * * * * if ! ping -c 1 -n 193.231.100.2  > /dev/null ; then /etc/init.d/dial start ; logger ADSL connection restarted ; fi

asta nu prea e script dar ma rog,tot nu a mers

script 3.

asta l-a facut cineva pentru mine,dar tot nu merge si nu ne-am dat seama de ce

root@time:~# cat autorecon.sh

  case $PASS in

  exit -$PASS
}

if [ -e $TIMER ]; then
  if [ $(date +%s) -lt $(sed -n "1p" $TIMER) ]; then
    PASS=$(sed -n "2p" $TIMER)
    rm $TIMER
  else
    rm $TIMER
  fi
fi

script 4 

asta este scriptul de dial pe care il folosesc cand dau /etc/init.d/dial start
sa se reconecteze dupa ce pica

root@time:~# cat /etc/init.d/dial
